Detailed explanation-1: -Number of explosions of piston on a single cylinder, four stroke cycle engine in 100 revolutions of the crankshaft. Ans. 50 explosions.

Detailed explanation-2: -In a four-stroke cycle engine (called a four-cycle), four strokes are needed to complete the operating cycle. The four strokes are as follows: • intake stroke • compression stroke • power stroke • exhaust stroke Two strokes occur during each revolution of the crankshaft.

Detailed explanation-3: -Internal combustion engines (with rare exceptions) operate on either a 2-stroke or 4-stroke cycle. In both types, each full rotation of the crankshaft produces two strokes of the piston, one moving inwards towards the head of the cylinder, followed by a second which withdraws the piston back to its initial position.

Detailed explanation-4: -An operating cycle requires two revolutions (720°) of the crankshaft. The four-stroke cycle engine is the most common type of small engine. A four-stroke cycle engine completes five Strokes in one operating cycle, including intake, compression, ignition, power, and exhaust Strokes.

Detailed explanation-5: -Intake stroke: The piston moves downward to the bottom, this increases the volume to allow a fuel-air mixture to enter the chamber. Compression stroke: The intake valve is closed, and the piston moves up the chamber to the top.
