What is the name of an engine that produces two rotations of the crankshaft from the four strokes of intake, compression, power, and exhaust?

The correct term for an engine that produces two rotations of the crankshaft from four strokes (intake, compression, power, and exhaust) is a four-stroke engine. In a four-stroke engine, each cycle requires four distinct movements (strokes) of the piston to complete one power cycle, meaning that the crankshaft rotates twice for every full combustion cycle.

This design is integral in internal combustion engines and is common in many vehicles, providing a good balance of efficiency, power, and emissions control. The structure ensures that the engine runs smoothly and efficiently, with the four distinct strokes contributing to various phases of the combustion cycle.

On the other hand, a two-stroke engine completes a power cycle in just two strokes of the piston, resulting in one crankshaft revolution. Diesel and reciprocating engines are broader terms that can encapsulate various engine types, but they don't specificize the distinct cycle pattern of intake, compression, power, and exhaust in relation to crankshaft rotation in the way that four-stroke engines do.
