Abstract One of the three major focus points of this paper is description of the technical evolution and trends in the future for petrol and diesel fuel injections systems such as carburetors, single/multi point injection and direct injection for petrol engine and indirect injection, direct injection like common roil for diesel engine.
The paper also discusses the various mechanisms that result in low or high cylinder pressure, provides a brief on the global warming phenomena as the increased use of automotives contributes to the green house gas emissions and finally a note on the issues related to automotive fuel systems. Introduction Fuel injection system, which has become a major form of fuel delivery used in automotive petrol engines, involves injection of fuel into an internal combustion engine. From the late 1980s this fuel injection system has replaced the carburetors, which was till then the most widely used in engines. Most of the fuel injection systems are designed and calibrated to handle gasoline or diesel applications specifically. The advent of the electronic fuel injection (EFI) systems has enabled the use of similar hardware for both diesel and gasoline ("Fuel injection", 2010). The EFI system uses a solenoid-operated injector to spray the atomized fuel into a 3-inch manifold near the intake valve. This technique is not being commonly employed in several vehicles or in some cases the air and fuel is directly injected. This system mainly depends on the injectors which come in various designs, cylinder pressure, fuel line pressure and other similar factors. ...
