What is the proportion of gasoline and oil in brush cutter?


The engine of brush cutter is two-stroke gasoline engine, and the general fuel mixture ratio is: FB/FC level engine oil 1:20-25, FD level engine oil 1:40-50.For example, the fuel oil ratio is 25:1, and about 40 ml of oil should be added to each litre of fuel.

Two stroke engines are highly efficient, and their crankshaft only needs to be rotated once to generate power.This simplicity requires that all systems of the engine be as simple as possible, including lubricating systems.The two-stroke engine is lubricated by a mixture of oil and gasoline.This mixture of fuel and oil can be purchased directly or mixed on its own.The following should be noted in the mix:

1. Refer to the manufacturer's recommendation to understand the ratio and grade of oil and fuel mixture.

2. Pour in the specified quantity and type of gasoline in a ventilated tank specially used for mixing.

3. Add appropriate amount of oil according to the proposal to meet the requirement of fuel oil proportion.If the fuel - oil ratio is 50:1, it is indicated that 1 ml of oil should be added to 50ml of fuel. If the fuel oil ratio is 25:1, about 40 ml of oil will be added to each litre of fuel.In addition, the manufacturer's recommended additives should be poured.

4. In the first 10 hours of the new machine, the oil mixture ratio is slightly thicker, followed by the normal ratio;The new machine is slightly thicker than the hot fuel in summer.
