Effect of Fuel Injection Rate Control on Reduction of Emissions and Fuel Consumption in a Heavy Duty DI Diesel Engine 2005-01-0907

In order to deal with upcoming and ever-more stringent diesel engine exhaust emissions limits, efficiency requirements, and after-treatment technology, further technology advancement has been required of the fuel injection system. In this research, CRS with the capability of varying the injection rate shape installed on a single cylinder and a multi-cylinder test engine, and tests were carried out. Results showed that with control of the injection rate shape, it became possible to control combustion and improve the NOx-fuel consumption and NOx-PM trade offs by offering the ability to optimize the injection rate. This leads one to believe that injection rate shape control is an essential function for future fuel injection systems.
