Abstract: This paper deals with the development of spark ignition engines that are designed to inject gasoline directly into the cylinder. Conventional spark ignition engine have defects such as high exhaust emission, low break thermal efficiency due to short circuiting losses and incomplete combustion which occur during idling & at part load operations conditions. The introduction of direct injection to the engine allows proper mixing of fuel & air giving complete control on combustion and emissions and thereby increasing power and efficiency. Another significant advantage of using direct fuel injection is that it is economical too as it provides a correct estimation of the quality of fuel required at proper time & provides control over combustion. Gasoline direct injection is becoming an important option to further optimize internal combustion engine.
