Review Paper on Experimental Investigation on Different Injection Pressure and Injector Holes Number in Stationary 4-Stroke Single Cylinder Diesel Engine Performance Using Bio Diesel Oil-Diesel Blends

The consumption of diesel is 4-5 times higher than petrol in India. Due to the shortage of petroleum products and its increasing cost, efforts are on to develop alternative fuels especially, to the diesel oil for full or partial replacement. Use of bio diesel in the diesel engine without modification that time performance of the engine is decrease because biodiesel viscosity and density effect the atomization so overall performance decrease. There are various factors that influence the performance of engine such as compression ratio, atomization of fuel, fuel injection pressure, and quality of fuel etc. Fuel injection pressure and nozzle holes number play an important role in better atomization of injected fuel allows for a more complete burn and helps to reduce pollution. In present work a single cylinder 5HP diesel engine is used to investigate the performance characteristics of bio diesel oil with diesel blends. We will jointly work on different injection pressure and injector nozzle holes number for improve the performance the engine.
