Dr.R.Kiruba Shankar, E.B. Priyanka, B. Saravanan.

The advent of increasing fuel consumption and stringent emission standards have driven the need to introduce new technologies and modifications that reduces fuel consumption while meeting increasingly stringent exhaust emission standards. A key objective is the potential combination of gasoline-engine specific power with diesel engine efficiency in a cost-competitive, production-feasible power train. One promising engine development route for achieving these goals is the potential application of lean burn direct injection for gasoline engines. In carburettors, the fuel is sucked due to the pressure difference caused by the incoming air. On the other hand the fuel is injected into the air for more powerful, fuel-efficient and environmentally friendly gasoline engines, developing highly efficient, Ultra Low Emission Vehicles (ULEV’s) by developing Gasoline Direct Injection (GDI) systems by controlling the mixture formation of a GDI engine under a wide range of engine operating conditions is essential to reduce smoke and particulate generation and optimize fuel economy. In this paper, a two-stroke engine is modified to work with direct gasoline injection system.
