Likewise, if the piston moves from the top of the cylinder to the bottom, this is also called a stroke.Ĭompared to two stroke engines, four stroke engines have more components and weigh more, but are more efficient. For example, when the piston moves from the bottom of the cylinder to the top, this is called a stroke.
One stroke is defined as the maximum distance a piston moves when traveling from the top of the cylinder, to the bottom of the cylinder, or vice versa.
there is one stroke for each of the suction, compression, power, and exhaust stages. It’s called a four-stroke combustion engine because there are four strokes to one combustion cycle. Each of a four stroke engine's strokes is used for one stage of the combustion cycle i.e. Four stroke internal combustion (IC) engines have been used for over 100 years and their design has not changed significantly since this time.
