Two-Stroke Cycle:

As like the four-stroke engine, the two-stroke engine must go by the similar four events: compression, intake, power, and exhaust. But a two-stroke engine needs just two strokes of the piston to complete one full cycle. Thus, it needs only one rotation of the crankshaft to finish a cycle. That means various events must occur during each stroke for all four events to be finished in two strokes, as opposed to the four-stroke engine whereas each stroke on the whole contains one event.

Within a two-stroke engine the camshaft is geared so in which it rotates at the similar speed as the crankshaft (1:1). The given section will elaborates a two-stroke, supercharged, diesel engine having intake ports and exhaust valves along with a 3.5-inch bore and 4-inch stroke with a 16:1 compression ratio, as it passes by one complete cycle. We will begin on the exhaust stroke. All the timing marks provided are generic and will vary from engine to engine.
