Abstract

Diesel engines are primary source of power for the heavy duty vehicles. The advantages of diesel engines are high fuel efficiency, reliability and durability. The performance and emission characteristics of diesel engine depend on many parameters. The parameter like fuel injection pressure plays an important role. Other parameters include compression ratio, atomization of fuel, injection timing, air fuel ratio, intake temperature and pressure and also based on piston design. Fuel injection pressure plays an important role in better and a complex burn to reduce the emission. The injection timing and due to which the formation of cavity and fuel dribble also studied and a brief analysis were given.
