Abstract
Diesel engine combustion quality is based on the formation of fuel-air mixture. Enormous efforts have
made to reduce the harmful diesel engine emissions. High engine noise, Particulate matter (PM) and NOx
production are the results of improper combustion process and considered as the major constraints. The
performance and emission characteristics of diesel engines depend on many parameters. Precise control
over the fuel injection process is one of the most important factors and plays a very important role in
combustion to increase the engine performance with minimal exhaust emission. The injection system must
satisfy high pressure capability, injection pressure control, flexible timing control, and injection rate
control. The purpose of this study is to find the performance and exhaust emission of diesel engines by
implementing the combination of various high injection pressures and variable injection timings. Present
paper is concentrated towords optimization of the best combination of high pressure injection with suitable
injection timing in a diesel engine fueled with pure diesel, to reduce the emission and fuel consumption
with increased engine power.
