Summary:

A very flexible choice of fuel injection characteristics can be obtained with an advanced electronic unit injector that has been developed with two electronically controlled valves. Single-cylinder engine tests have demonstrated the potential of this advanced EUI system for a heavy-duty diesel engine. Substantial increases in injection pressure can be programmed electronically at individual engine speed/load conditions, compared with a baseline EUI system, to provide much faster rates of air/fuel mixing. Simulated US and European emissions cycle results, with the optimised two-actuator EUI and EGR, show substantially improved soot particulate versus NOx results and lower BSFC compared with a baseline EUI result. A high-pressure post injection has the potential to give further soot reduction
