The world’s rapidly dwindling petroleum supplies, their rising cost and the rapid growing of automobile have led to an intensive search for alternative fuels to replace diesel fuel. Agriculture and transport sectors consume maximum percentage of petroleum based fuels, where diesel engine happens to be the prime mover. There is a variety of alternative fuels available as renewable fuels to replace diesel. Vegetable oils and their properties being close to diesel so it may be considered as a promising alternative fuel for the diesel. The high viscosity and low volatility of these vegetable oils are the major problems when they use in diesel engines. Such type of problem can be addressed by the process of transesterification. In the present work, experiments were conducted on four stroke, single cylinder diesel engine using cotton seed oil methyl esters as fuel to study the engine performance and emission at different injection pressure. The effect of injection pressure on the performance and emission was studied at three different test pressures. Non edible cotton seed oil bio diesel was tested for their use as substitute fuels for diesel engines. The results showed a better performance at an injection pressure of 200 bar.
