In a conventional Otto cycle engine, each cylinder performs four strokes per cycle: intake, compression, power, and exhaust. This means that two revolutions of the crankshaft are required for each power stroke.
A typical Otto cycle engine functions with each cylinder undergoing four stages within a single cycle: drawing in air, compressing it, producing power, and expelling exhaust gases. Consequently, two revolutions of the crankshaft are necessary to generate one power stroke.
