A fuel-injecting mechanism is installed on a diesel-powered engine, playing a crucial role in introducing finely atomized droplets of diesel fuel into an engine's cylinders during a combustion process. Diesel engines have traditionally employed mechanical injection pumps that produce precise volumes and pressures required for smooth diesel fuel introduction into individual cylinders through a fuel manifold or injectors. However, recent advances in engineering technology have introduced alternative approaches that enhance the efficiency of fuel introduction systems for improved overall engine performance, particularly at low temperatures when high-temperature fuel atomization is less efficient. An electric fuel pump now often takes the place of these traditional mechanical pumps in diesel engines equipped with electronic fuel injection (EFI). The use of this electronic system simplifies fuel system maintenance as electrical and electronic parts can easily be inspected or replaced without extensive disassembly, making repair work more efficient. Another development contributing to diesel engine improvement is fuel rail technology, particularly piezoelectric high-pressure injectors which are capable of precisely controlling high-pressure delivery into a small atomizing nozzles inside each injector body, thereby reducing the potential for oil smoke emission and lowering hydrocarbon emissions as the finely metered atomization takes effect.
