An Investigation and Effect of Nozzle Parameter on Atomization

The scope of diesel engines in the last years in the vehicles area is increased due to their high efficiency and fuel economy. In present diesel engines the fuel injection systems has been designed to achieve higher injection pressure for the purpose of good atomization which ultimately results in decrease the exhaust emissions. We know that controlling combustion helps in reducing emissions. Atomization of fuel is very important part in controlling combustion inside a direct injection engine. Atomization is first occurs in the vicinity of the orifice due to turbulence and cavitation.
