2 stroke engine port timing diagram: The time of opening and closing of the ports with respect to the crank angle has a great impact on the performance of 2 stroke engine. The port timing diagram indicates the operating of the ports with respect to the crank angle. Below fig. a shows the port timing diagram for the 2-stroke SI engine.. This document summarizes the key differences between 2-stroke and 4-stroke diesel engines. It explains that a 2-stroke engine completes a power cycle in two strokes of the piston over one crankshaft revolution, while a 4-stroke engine requires two crankshaft revolutions to complete the power cycle. The basic parts of a diesel engine are described.
Inlet and Exhaust Manifold: These are connected to inlet and exhaust port and regulate the flow of charge and exhaust gases. Flywheel: It need smaller flywheel compare to four stroke engine because less power fluctuation. Crankcase: This is the part where crankshaft situated.The inlet port is also connected with crankcase. First charge enters into crankcase and send to combustion chamber.. 2. Two stroke cycle engine. - When the cycle is completed in one revolution of the crankshaft, it is called two stroke cycle engine CONSTRUCTION OF AN IC ENGINE I.C. engine converts the reciprocating motion of piston into rotary motion of the crankshaft by means of a connecting rod. The piston which reciprocating in the cylinder
