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.
The four-stroke engine produces 1 power stroke for every 720 degrees of crankshaft rotation.
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.
180 degrees per 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
90 degrees would be a half stroke.
In a 4-stroke engine, one complete engine cycle consists of four strokes: intake, compression, power, and exhaust. This cycle requires two full rotations of the crankshaft, which equals 720 degrees of crankshaft rotation. Each stroke corresponds to 180 degrees of crankshaft movement, collectively completing the cycle.
