摘要

Transportation and industry are two major sectors consuming diesel fuel. Now it has become a challenge for researchers to conserve fossil fuels, which are going to be depleted in near future. In this connection commitment of researchers played a key role in novel design of vehicle. The industry has already improved engine performance significantly with the new technologies and also reduced the pollutant emission levels. More recently, electronically controlled technology is being used in automobile industry as a tool to improve the phase of change. In the advanced technologies of automobile industry the cams are playing a vital role to suit for the ground conditions and fuel consumption. The combustion processes is controlled by operating opening or closing of inlet and exhaust valves. The combustion characteristics are greatly influenced with the fuel preparation process and the distribution of fuel in the engine which is, in turn, controlled by the in-cylinder fluid mechanics. Fuel injection introduces the complexity of describing the physics of vaporizing two-phase flows that vary spatially and temporally from very dense to fairly dilute. Combustion processes and turbulent fuel air mixing are responsible for emission formation. There is a need to have a thorough understanding of these processes to improve performance and reduced emissions without compromising fuel economy. In view of this, an attempt is made to study performance parameters and exhaust emissions for different speed operations.
