Asthe name implies, a two-stroke engine is a type of internal combustion (IC) engine that produces work in two strokes (i.e., up and down moment) of the piston. The piston travels up and down once, i.e., one revolution of the crankshaft, to complete its power or thermodynamic cycle. The history of these engines dates back to 1881, when it was

In 1878, a British engineer introduced a cycle which could be completed in two strokes of piston rather than four strokes as is the case with Thefull form of the CI engine is a compression ignition engine. A CI engine is an internal combustion engine where the use of hot compressed air ignites the fuel. When air is compressed, heat is created, which is used to ignite and burn the fuel. In this engine, the suction stroke draws air in, which is then compressed during the compressionScavengingin Diesel Engines. Scavenging is the process of removing exhaust gases from the cylinder after combustion and replenishing the cylinder with fresh air. Efficient scavenging is necessary for good combustion of fuel inside the engine cylinder. The passage of scavenge air will also assist cooling of the cylinder, piston and valves.Amarine diesel engine directly coupled to the propeller shaft must be reversible. The reversing system must be capable of turning the engine in opposite direction by compressed air. The condition which must be satisfied are : 1. change in the sequence of starting air admission. 2. set the fuel pump timing to reverse running direction. bmLPLpH.
