the power stroke
In a 2 stroke, every second stroke of the engine is a power stroke. In a 4 stroke, every 4th stroke of the engine is a power stroke. Knowing this, a 2 stroke has double the power as a 4, in the same cc
the power stroke is the downward stroke of the piston, how much power is created in this motion is judged in horse power.
two stroke engines have a power stroke every second revolution of the crank shaft. four strokes have a power stroke every fourth revolution of the crank shaft. that is why a 125cc two stroke has about the same power as a 250cc four stroke.
2-stroke engines produce much more power than 4-stroke.
Suction stroke, compression stroke, power stroke & exhaust stroke
The four strokes of an internal combustion engine are intake, compression, power, and exhaust. During the intake stroke, air and fuel are drawn into the combustion chamber. In the compression stroke, the mixture is compressed. The power stroke is when the compressed mixture is ignited to create power, while the exhaust stroke expels the burned gases from the chamber.
2 stroke
The exhaust stroke is the 4th stroke in a 4 cycle engine. 1st is the intake stroke, 2nd is the compression stroke, 3rd is the power stroke and the 4th is the exhaust stroke.
end of compression stroke and power stroke
The exhaust stroke is the 4th stroke in a 4 cycle engine. 1st is the intake stroke, 2nd is the compression stroke, 3rd is the power stroke and the 4th is the exhaust stroke.
The power stroke. The order is intake, compression, power and exaust. The piston moves down on intake and power but is only forced down on the power stroke
