Open publisher page 18 citations

Abstract

Diesel engines are the 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. One of the important factors which influence the performance and emission of diesel engine is fuel injection pressure. An experimental study was performed on a light duty direct injection diesel engine at 150 bar, 200 bar and 250 bar injection pressure to study its effect on performance and emission. The injection pressure was changed by adjusting the fuel injector spring tension. The performance and emission characteristics were presented graphically and concluded that they were found better at the fuel injection pressure 200 bar for the light duty engine.
