Trimmer for grass gasoline what gasoline pour. Obtaining a mixture

How much oil should be poured into a trimmer for grass per liter of gasoline

Gasoline braids are fairly common tools used by owners of garden and household farms for mowing grass and hay harvesting. The more common names of the tools are the terms “trimmer for grass” and “lawn mower”. The main difference is hidden in the design of the motor. the expensive segment of the devices is equipped with four.stroke models, and cheap ones. two.stroke. The last option has advantages, including a small mass, ease of use, as well as low cost.

The most important condition for the operation of two.stroke models is the preparation of the fuel mixture, based on the proportion of gasoline and oil determined by the manufacturer. The simplified engine design does not provide a separate lubrication channel, so the engine oil is added directly to the gasoline. Violation of the correct proportion leads to a significant decrease in the resource of the tool and even to its breakdown. We will figure out which composition is required for gasoline trimmers, how to prepare the mixture correctly and what it can affect.

Selection of gasoline for a trimmer for grass

For some reason, everyone prefers to choose a brand of gasoline for motorcycles at their discretion. This is an erroneous approach, because, first of all, it is necessary to carefully study the instructions where the manufacturer’s recommendations for the choice of fuel are given. But this is also not a guarantee, since unearthly fuel can be sold under different brands (which differ in many manufacturers), which are significantly different in composition. Therefore, it is necessary to focus precisely on the main characteristics in order to choose gasoline for a certain model of a trimmer for grass.

Manufacturers of benzo-tools recommend using AI-92 gasoline brand for work, but for more expensive types you will need fuel with a higher octane number-AI-95. Any brands, in the marking of which the number 90 and less appear, is not suitable for benzos, since they lead to rapid wear. The problem develops due to unscrupulous fuel manufacturers, which are sold under the guise of 92nd a completely different brand. The following situation develops:

• The passport for gasoline equipment has a recommendation for the use of gasoline with an octane number of at least 92;
• The conscientious owner goes to a gas station, where the lowest price and with a clear conscience floods such a fuel in a motorcycle;
• As a result, the service life is reduced, since often under the guise of AI-92 AI-80 and AI-76 is sold.

To avoid such a situation, you need to select one gas station, where the proven gasoline is sold (this can be determined by the reviews of regular customers). It is also important where to fill the fuel after the purchase. for this you need to use only metal containers (plastic. prohibited).

The option is preferred when it is possible to buy gasoline for a trimmer for high.cleaning herb specifically for garden equipment. Then you can be confident in its quality and protection against fakes.

Differences in gasoline engines

Gasoline engines are two.stroke and four.stroke. To understand the difference, you need to know the two nuances: firstly, that during the engine operation a number of transition processes occur, and secondly, that the tact means the movement of the piston from one extreme position to another, while the direction of movement does not have a value. The essence of the classification of engines is that the entire cycle of transition processes in one case is repeated in two tacts, in the other. over four.

The differences between 2t and 4t, which relate directly to the process of refueling, can be understood without even going into the subtleties of the main nodes. In a two.stroke engine, the supply of the fuel mixture to the cylinder, and the release of the exhaust gases occurs almost simultaneously. In this case, the fuel fog initially enters the crankcase, where the crankshaft is located. When moving down, the piston squeezes part of the mixture from this chamber to the working area through the window in the cylinder wall.

In a four.stroke engine, the combustion chamber is separated from the crankcase. The supply of fuel.air mixture occurs through the inlet valve, the release of the exhaust gases. through the graduation. Dutch control is carried out by a separate node driven by a crankshaft, while the procedure for their opening and closing is synchronized with the piston strokes. Due to the separation of the working area from the crankcase and the four.stroke order of operation, the complete combustion of the fuel and the almost complete removal of the exhaust gases from the working area before injection of the next portion of the mixture are ensured.

How lubrication systems work

Both types of engines contain a fair amount of moving elements. To increase the resource of their work, the presence of lubrication is required. Its feed on two-stroke and four-stroke engines is carried out differently and this kind of nuances are directly related to the procedure for refueling and maintenance.

The supply of lubrication in a two.stroke engine is performed along with the fuel mixture. The oil dissolved in fuel is sprayed along with gasoline in the carburetor, the formed fog enters the chamber. The configuration of the channels is organized in such a way that the route of sprayed lubrication is as long as possible and passes through the main moving nodes. At the same time, due to the special properties of the oil, most of it settles on the metal parts, and the purified fuel is transmitted to the working area of ​​the cylinder. It is thanks to these properties that oil for two.stroke engines is radically different from other types.

In a four.stroke engine, the oil in an isolated crankcase is constantly. Its level is controlled in such a way that the crankshaft neck periodically plunge into the oil bath. At the same time, a balanced ledge when rotating due to centrifugal force sprinkles oil through the internal volume, so the lubricant enters the piston cavity and onto the tarnished finger, as well as on the walls, due to which it is effectively cooled. So that the oil does not fall into the combustion chamber, an additional corrugated ring is installed on the piston, which relieves oil residues from the cylinder walls when the connecting rod moves down.

What gasoline in the Viking lawn mower

Lawn mowed “Viking” Electronic and gasoline self.propelled: reviews

The Austrian company Viking announced the first time for itself in 1981. Henry Lechner is considered to be its founder. In the small city of Kufstein, he was engaged in the creation of garden grooms. The world Viking saw the 1st lawnmand in 1984. Since 1992, the above company began to intensively develop.

The reason for this is considered to be a “Viking” connection with the company “Steal”. They were engaged in the creation of chainsaws. But since 2001, Viking can be trampled by simply not a small assortment of lawn mowers that are in great demand in the world. Today, this trademark has become a favorite for the production of garden tools.

What is the difference between lawmakers Viking?

First, it is important to note that the buyer has the opportunity to choose a lawn mower that works either on a gasoline or on an electronic engine. There are also battery models.

Their power in average ranges in the region of 4 kW. The width of the capture may vary, as well as the height of the mowing. The cutting system, usually there is a centralized.

If we consider small.sized models, then they are equipped with an eight.speed mechanism.

Herbal collectors in the set are cut quite high.quality. Their volume in the main thing is depending on the power of the lawn mower. Frames in all models are installed enhanced. The lawn mowers do not actually need to.

You can clean the blades after the lawn can easily. Wheels in devices are available with double bearings. Because of this, their service life is significantly increased.

Repair of the Viking lawn mower can be carried out exclusively in the service center.

Reviews of gasoline modification “Viking MV 248”

This gasoline gasoline “Viking” reviews has excellent. Many buyers of this model prefer due to low fuel consumption. The productivity of the device with all this is within the boundaries of the norm. The power of the designated lawn mower is 4 kW. Knife capture width. 46 cm. The height of the mowing with all this is equated 25 mm minimum.

You can adjust it with a lever. The cutting system in this case is installed centralized. The power of the device can be changed step. Viking MV 248 lawn mower knife in a standard set enters a metallic. In total, manufacturers have provided 8 different modes. For giving, this lawn mower is perfect, and on average it is able to process an area of ​​1200 kV. m.

What are they saying about the electric model ME 235?

The designated lawn mowers “Viking” reviews are more positive. This model is very ordinarly in calling. The handle is installed quite high.quality, and keeping the device is left with jewelry accuracy. This lawn mower does not actually need an overcoming.

The blades in the device are provided very sharp. With a small grass, the lawn mower cooles successfully. Of the shortcomings, it is necessary to emphasize the small power of the unit. Such a macar, it is more advisable to use it on small lawns. This modification consumes electricity within the boundaries of the norm.

The engines in the lawn mower of IM 235 break quite occasionally.

Overview of the lawn mower MV 448

This self.propelled lawn mower “Viking” in the middle of other devices is its own compactness. The cutting system in this case has a rotary.

Because of this, the lawn mower can work for a long time without interruptions. The nominal power of the designated unit is within the boundaries of 3 kW. The small mowing height is 20 mm.

The width of the capture, according to the view of many, is good and 30 cm is equated.

The maximum of the height of the mowing user is able to set 60 mm. The engine in this case the manufacturer installed asynchronous. Wheel drive has a rear type.

The deck of the Lawn mowed MV 448 is made one hundred percent of plastic, but with all this it is quite strong and the load can withstand huge. In terms of noise, this model does not differ from ordinary lawn mowers.

At a distance of 5 meters, the device MV 448 produces 50 dB. There is only one nozzle in a standard set. Knives manufacturer are installed lobe type.

Advantages of the MV 2 model

This model is valued by consumers for their highest performance. It is capable of unprinciply to work out about 3 hours. With all this, the engine does not actually overheat. This was achieved due to a good cooling system. But the disadvantages of this modification also have.

What gasoline should be poured into the Viking lawn mower and what kind of oil and in what proportion how often to change the oil. First you need to emphasize sufficiently thin knives in the kit. To regulate the height in this model comes out with great difficulty.

This is due to the fact that the lever is fixed quite firmly. It is also fundamentally not to note the overstated vibration. If you work on an uneven surface, then shaking is created enough. As a result, the pen begins to vibrate very.

Keep under control in such a situation the lawn mower of MV 2 is difficult.

Viking Lawn mowed oil change at the end of the season

oil substitution at the end of the season. Four.stroke engine according to a lightweight scheme without oil.

Viking Ma 339 gasoline gas mowers

This model is able to boast of just excellent characteristics. The power of this unit is 4 kW. A bag for collecting grass is quite voluminous. During operation, it is disconnected very quickly for cleaning.

You can adjust the height of mowing in this case. The width of the capture of knives is optimal. The cutting system in the lawn mower provides for a rotary. There is only one nozzle in a standard set. There are five modes for a choice.

You can also adjust the height of the handle in the MA 339 model.

Consumer reviews about MV 3

This Viking lawn mower is not suitable for everyone, but it still has certain advantages. First of all, consumers note convenient management.

You can adjust the speed of knife speeds quite simply using one switch. The shutdown button is in a convenient place and it’s good. Of the shortcomings, quite large dimensions of the device should be noted.

Features of refueling motorcycles

When the mixture is ready and ready for use, it must be carefully poured into the fuel tank. Since gasoline is toxic fluid, when working with it, you need to observe safety precautions. Work must be carried out in measured weather and away from third.party people. Also to pour fuel into the tank, you must use a funnel or a funnel with which you have previously diluted the mixture. In an unpleasant case, the mixture may blur, go unnoticed and inflamed when the engine is heated.

The fuel bank itself must be cleaned of external pollution and only then unscrew its cap to refuel it with ready.made fuel. After filling the combustible, the reservoir should not remain open, since insects or soil can get into the tank and clog the fuel filter. The fuel should be poured into the tank of the designated mark either less, and then in the time of operation.

When storing the container, it is necessary to close tightly with a lid. Store combustible in a cold room, outside the sun’s rays. It should be kept in your head that with prolonged storage of consistency, the oil liquefies and loses its characteristics.

Choosing oil mushrooms

For trimmers engines, it is necessary to choose oils with “2T” labeling, which are used for ICE with a volume of 50 to 200 cm and have air cooling. First of all, when buying oil, it is worth paying attention not to the price, but the protective properties of the material, since slight savings can subsequently become a real headache for the owner and, as a rule, large costs.

Two.stroke oil for lawn mower

The main factor that determines the quality of the oil for a trimmer for grass is an alkaline number. It is this component that excludes the oxidation of the rubbing parts and slows down their destruction. During operation, the oil gradually loses its alkalinity and becomes oxidized. The optimal level of acidity (pH) should not be less than 8-9 units.

The viscosity of the oil for motorcycles also has a great influence on the process of gasoline tools. This indicator determines the possibility of operating a trimmer for grass at different temperatures. For example, summer grades of lubricants thicken even with a slight drop in temperature. Due to the use of the lawn mower exclusively in the spring-autumn period, oil with summer marking will be an excellent option.

The temperature of the outbreak for a trimmer oil for grass should be more than 225C, otherwise the oil will quickly burn out, and the piston group will be subjected to intensive wear.

What to look for when choosing oil?

Modern two-stroke engines of Motokos are seasoned with a mixture of AI-92 gasoline and oil marking “2T”. The use of fuel with a higher octane number will contribute to an increase in the temperature of the flash and, as a result, burning out lubricants.

Varieties of STIHL oils

Undoubtedly, the best oil for a trimmer for grass is recommended by the manufacturer, however, the owner does not always have the opportunity to purchase precisely a “branded” lubricant. Experts recommend Shell Helix Ultra, based on PurePlus technology, which helps to improve the basic properties of lubricants.

For gasoline trimmers of the German manufacturer, STIHL must use the STIHL HP Ultra, Stihl HP, Stihl HP S oils. The budget substitute can be the products of the Vityaz company, which in its properties is the most similar to the recommended material.

Fuel consumption and on what it depends?

The fuel consumption of gasoline lawn mowers is measured in l/h, that is, the number of liters of gasoline that the engine consumes during mowing grass per hour.

This parameter depends on:

The more powerful the motor, the more fuel it consumes, because the energy of rotation of its shaft is formed as a result of combustion of gasoline and the appearance of exhaust gases that pushing the piston, which through the connecting rod turning the crankshaft of the engine.

The larger the width of the mowing, the more energy you need to produce the engine in order to effectively shake the grass. The self.propelled drive takes part of the energy manufactured by the engine for the movement of the lawn mower, which means that to maintain the same efficiency of mowing, the production of additional energy is necessary, which leads to an increase in fuel consumption.

The thicker the grass, the higher the load on the knife, which means that the more energy it is necessary to develop the engine to maintain the efficiency of mowing.

The mowing modes are of considerable importance, because in the mulching mode, as well as with untimely emptying of the grass collector, the fuel consumption increases.

Manufacturers sometimes indicate fuel consumption for a particular model, but these data are averaged, so the permissible error is ± 30%. You can more accurately determine this parameter using a field test, for which exactly 1 liter of gasoline is poured into the tank and the grass is mowed until the engine is stalled, and then this data is transferred to the necessary (l/h) format.

Periodic measurement of fuel consumption will help to track the condition of the engine and its systems, because if the consumption under the same operating conditions has increased, then the motor needs to be maintained.

How to refuel a gasoline lawn?

For refueling, pure unhealthy gasoline is used, which was stored for no more than a week in a clean container without oil residue.

It is necessary to pour fuel using a watering can or a special tip worn on the canister to avoid spilling gasoline.

After all, the spilled fuel is a serious fire hazard, and also makes an unpleasant odor and stains hands or clothes.

You can not pour a full fuel tank, because during operation the engine releases a lot of heat, some of which reaches a gas tank of the lawn mower and at least a little, but heats its contents. This leads to increased fuel evaporation and an increase in pressure inside the gas tank, which also leads to an increase in pressure inside the fuel system.

If this happens, then the fuel mixture entering the cylinder will be richer, which means that the fuel contained in it will not burn completely, but will burn out in the engine head and its silencer, which will reduce the resource of these parts.

Before pouring fuel, it is necessary to carefully read the instructions for the operation of a gasoline lawn mower, because there is the maximum level of fuel, which cannot be exceeded.

In order to fill the fuel, you need to do the following:

• stop the engine if the grass was mowed before this, then wait 5-10 minutes so that the motor and the surrounding space are cooled (if the mower is only delivered to the place of work, then this item is not required);
• clean a cloth to clean the fuel tank cover, as well as the space adjacent to it from beveled grass or dust;
• unscrew the lid and remove it to the side;
• Using a watering can or a special nozzle on the canister, pour fuel into the tank;
• put on, then wrap the lid;
• Wipe the lid, pouring neck and tank with a clean dry rag.

Refueling a two.stroke motor

Do not use pure gasoline. Be sure to dilute the oil for them. The fact is that a two.stroke engine does not have a separate oil tank and an oil dispenser. Lack of 2-stroke motor-undersized gasoline. During the operation of the engine, the smell of overheated oil is also felt. it also does not completely burn out. Also do not save in oil. With its lack, the pistons move back and forth with great friction and branding. As a result, the cylinder and the piston shaft will be faster.

Mineral oil is poured into gasoline usually in a proportion of 1: 33.5, and synthetic. in a ratio of 1: 50. The norm for semi.synthetic on average is 1: 42, although it can be adjusted.

For example, 980 ml of gasoline and 20 ml of synthetic oil are poured into a liter tank. If there is no measuring glass-9800 ml of gasoline (almost 10-liter bucket) and 200 oils (one faceted glass) will go to two 5-liter canists (one faceted glass). Overflowing oils by at least 10% will lead the engine to the construction of its parts with a layer of carbon monoxide. Power output will become ineffective, and gasoline consumption may increase.

Fueling a four.stroke engine

The complicated design of the “4-tsniki”, in addition to two additional compartments with pistons, has an oil tank. The oil dosage system (Carter) itself introduces oil in the proportion established by the manufacturer. The main thing is to check the level of oil in the system in a timely manner. If necessary. share, or better. completely replace the oil, draining its development.

Do not pour fuel and oil under the lid of the neck of the tanks. When the burned part is heated, the oil pressure in the engine system will increase sharply.

As a result, it can stall, having worked for only 2-3 minutes-until the amount of fuel and oil in tanks will decrease by at least a few percent. If the upper mark is absent, pour oils and gasoline into tanks less by 5-10%than they accommodate.

Do not skimp on the quality of gasoline or oil. Poorly peeled gasoline and the “wrong” brand will quickly clog the engine. This will lead to a forced sink of the latter. and it is good if the restoration is limited to washing, and will not go to the stage of overhaul.

Why mix oil for grass with gasoline

The two.stroke engine has a simple and, at the same time, extremely effective design:

• The piston makes a working move every second clock;
• The lubrication of the cylinder is made by oil dissolved in gasoline;
• Removing combustion products occurs due to compression, without a special mechanism.

All this led to the creation of a family of small engines that successfully adapted in household and professional equipment:

Due to the design features, it was possible to achieve the desired fuel consumption only on small engines with a power of 15. 20 liters.strength. This indicator looks especially good in the 1. 5 liter range.With. Here, the full weight and engine dimensions correspond to the consumption of gasoline.

With increasing size, the area of ​​inlet and graduation channels increases. The process of removing gases and supply of fuel deteriorates sharply. In this regard, it took a transition to a more effective system of burning a gasoline mixture, which would provide for the presence of motor service systems. Four.stroke models intercepted the palm of the championship among high power units. Their unification into multi.cylinder structures allowed the creation of special systems associated with the formation of the composition of the fuel mixture, lubrication and other things, which favorably affected the consumption of gasoline.

The lubrication of the rubbing elements of the piston and the cylinder of the two.stroke engine occurs with oil, which is in a certain proportion in the fuel. Gasoline burns, and the oil settles on the surface of the cylinder, reducing friction of the rubbing parts. Lack of lubrication leads to damage to the cylinder, up to jamming. In the case of an excess, under the influence of high temperatures, the thermally modified product in the ring grooves is deposited. Compression falls, and with it the power.

Fuel consumption

One of the most important issues that arises for the owners of the tool, because everyone wants to know what to expect.

The volume of almost all containers is approximately 500 ml. If the power of the chainsaw is 2 kW, the fuel mixture consumption will be approximately 1.2 liters per hour. Simply put, such a tool can work at a maximum speed within half an hour without a break. If the chainsaw is not so powerful, its volume will be smaller. Thus, the user can independently control the fuel consumption.

Over time, the user will learn to serve his tool without outside help. The main task will be to maintain a business unit in good working condition using high-quality fuel mixtures. When preparing flammable liquids, follow the safety rules. This will help save the tool and not harm yourself and the environment.

We deal with the choice of gasoline for the AI-92 or AI-95 lawn mower

How many people, so many opinions, which applies not only to the choice of oil for a trimmer for grass, but also gasoline. Similarly, in order not to make a mistake with the choice, it is recommended to use gasoline of the brand that the manufacturer recommends (indicated in the manual to the tool). However, not everything is so simple here, since at each gas station of the gasoline brand they are only called the same, but have a completely different composition. It is required to figure it out, and come to a single conclusion about which brand it is better to pour gasoline into a two.stroke engine for your trimmer for grass.

Manufacturers recommend using A-92 gasoline for their technique, and some models require the use of the A-95 brand that do not contain ethyl alcohol. It is not recommended to use gasoline of the AI-90 brand and below, as they will entail the rapid wear of engine parts. Buying gasoline of one brand, one cannot be 100% sure that it is true. The result is the following picture:

• The manufacturer recommends pouring fuel into a trimmer for the grass of the AI-92 brand
• The summer resident uses only gasoline of this brand, but buys it at gas stations, where the price is lower or where you have to
• This negatively affects the internal details of the motor, since at one gas station it is really high-quality AI-92 gasoline, and at the second, at best, if it is AI-80, not AI-76

As a result, the engine suffers, and after a couple of years of operation a new trimmer for the grass, it is necessary. In order not to analyze the quality of fuel or buy only expensive gasoline, it is recommended to refuel only at one gas station. At gas stations, gasoline is poured only into metal canists, not plastic.

There are manufacturers that produce special cleaned fuel for two.stroke engines. If this option is selected, then you will not need to choose the best gas station, a brand of gasoline and control its storage periods.

Conclusion on the choice of gasoline for a trimmer for grass!

In a trimmer for the grass, you need to pour gasoline of the brand that is recommended by the manufacturer. If you pour A-95 gasoline in a trimmer for grass, instead of A-92 (which is recommended by the manufacturer), then the engine will warm up faster and work unstable. It is also better to choose gasoline A-92 ECTO, which has improved characteristics in terms of environmental friendliness.

Fuel consumption and on what it depends?

The fuel consumption of gasoline lawn mowers is measured in l/h, that is, the number of liters of gasoline that the engine consumes during mowing grass per hour.

This parameter depends on:

The more powerful the motor, the more fuel it consumes, because the energy of rotation of its shaft is formed as a result of combustion of gasoline and the appearance of exhaust gases that pushing the piston, which through the connecting rod turning the crankshaft of the engine.
