Summary:

1.ABSTRACTIn an effort to protect the earth's environment, emission regulations in the diesel engine field are becoming increasingly strict. One way of meeting these regulations is to atomize the fuel spray by using a fuel injection system with high-pressure injection, which activates engine combustion.With current in-line pump systems, however, it is still possible to satisfy the demand for cleaner emissions by improving the fuel spray, through measures such as reviewing high-pressure injection and initiating improvements in the nozzle. This report describes the new in-line pump system for medium duty diesel engines to meet future emission regulations.In this report, we will describe how analytical technology, such as computer simulation, was used on the pump side to make improvements for higher injection pressure. We will also describe how this technology was used on the nozzle side, to improve fuel spray characteristics with high flow velocity at the injection nozzle spray holes, and thus created a high-performance, highly reliable in-line pump system capable of meeting upcoming regulations on emissions
