The length of the crankshaft throw is the stroke of the engine.
Both con-rod length and shape of the crankshaft affect piston stroke
the power stroke
The Crankshaft!
It refers to the throws of the crankshaft/distance the piston moves. It usually is compared to the bore of the engine. An example a 302 4"bore x 3"stroke is a short stroke motor, by comparison a 5.4L ford v8 3.552" bore x 4.165" stroke.
in my opinion a two stroke engine is a better quality engine as compared to a four stroke engine!
Why the fuel consumption is less in 4 stroke engine as compared to 2 stroke engine
A two stroke engine has half the strokes of an otto (or four stroke) engine, therefore it takes two crankshaft roatations to complete a cycle on a four stroke engine and only one revolution in a two stroke engine. There are several types of two stroke engines, the different types have to do with how the receive the air/fuel mixture, also you have two stroke diesel engines.
The four-stroke engine produces 1 power stroke for every 720 degrees of crankshaft rotation.
180 degrees per stroke.
90 degrees would be a half stroke.
one rotation
