Abstract

In present study, A spark ignition and a compression ignition engine with uniflow valve scavenging of the cylinder and a transfer valve in the piston crown have been described. A great disadvantage of two-stroke engines is ports which are made in the cylinder bearing surface. Under the heat which is realised during the combustion, the thermal extension of the range in proximity of the ports and other parts of the cylinder is different and so the distortion of the geometry of the cylinder liner surface force the designer to make the clearance between the piston and the cylinder liner bigger. This paper presents the critical review to study the effect of fuel injection timing and scavenging using diesel on the combustion and emission characteristics of a single cylinder, two stroke, air cooled direct injection diesel engine. It is well known that injection strategies including the injection timing and pressure play the most important role in determining engine performance, especially in scavenging emissions. However, the injection timing and pressure quantitatively affect the performance of the diesel engine.
