The people in our society are highly depended on petroleum for their activities. The petroleum is a finite source and it produce several problems such as rising carbon dioxide level in the atmosphere. Around 75% of fuel produced is used for as an energy source for transportation, heat and electricity generation. This study was carried out to understand the effect of fuel injection pressure on the CRDI engine for the performance, combustion and emissions. This work has been done out on a four stroke, single cylinder diesel engine. The fuel injection pressure was varied from 400 bar, 500 bar and 600 bar by having the fuel injection angle as 20°bTDC. The collected data were analysed for various parameters such as brake specific fuel consumption (BSFC), brake thermal efficiency (BTE), CO, CO 2 , HC, NO x and Smoke emissions for diesel fuel. CO, HC and smoke emissions were reduced by increasing the fuel injection pressure. NO and CO 2 emissions were increasing by increasing the fuel injection pressure. This is due to injected fuel droplets find smaller as the injection pressure increase, which leads to improve atomization of the fuel. The BTE and SFC were not much varying.
