NAME: MOBEEN AHMADREG# 16-ME-057 OBSERVATIONIn this experiment we observed that:In this experiment we observed that:1.2-Stoke diesel engine is an internal combustion engine.2.It work on the Diesel cycle.3.It consists of crankshaft, cam shaft, fuel injector, piston, intake valve, exhaust valve, fuel chamber etc.4.In 2-stroke diesel engine there are pistons that completes two separate strokes while turning the crankshaft.
i.1-Stroke: As the piston starts rising from its BDC position, it closes the transfer and the exhaust port. The air which is already there in the cylinder is compressed. At the same time with the upward movement ofthe piston, vacuum is created in the crank case. As soon as the inlet portis uncovered the fresh air is sucked in the crank case. The charging is continued until the crank case and the space in the cylinder beneath the piston in filled with the air.ii.2-Stroke: It is the power stroke; as the piston reaches TDC, the compression stroke ends. Fuel is injected at this point and the intense
