摘要
The two stroke engine is relatively small and has higher Power to weight ratio, simplicity of operation and less cost. However these engines have high exhaust emission and low brake thermal efficiency due to short circuiting losses and incomplete combustion. To eliminate short circuiting losses, externally scavenged engine is developed in I.C.Engine laboratory. In this study, effects of externally scavenged system on performance and emissions of two stroke engine is investigated at different loads and speedsusing aluminium as piston material. Performance of externally scavenged engine is compared with crank-cased scavenged engine. Result show that brake power and brake thermal effeciency of externally scavenged engine is improved due to supply of leaner air-fuel mixture to the engine. The most oustanding result of using externally scavenged system is the significant reduction in the pollutions emitted from engine.
