EN Experimental results have shown that high exhaust emissions in diesel engines can be avoided by employing special injection strategies. This is because an increased homogeneity of the fuel-air mixture created by some injection strategies has a capability to improve NOx-PM trade-off. Therefore, the mixture quality is a primary parameter that needs to be controlled in order to enhance engine power output and low exhaust emissions. In fact, the combustion strategy employing multiple injections and EGR technique tends to introduce better fuel economy as well. In the experimental work presented in this paper the combinations of pilot quantities, injection pressures and dwell periods (time lapse between Pilot Injection Timing and Main Injection Timing) have been tested on a modern V6 diesel engine. The engine utilises a common rail direct injection, is fitted with twin turbo-charged variable turbine geometry (VTG) turbochargers and is fuelled with ultra low sulphur diesel (ULSD). The overall results show that these strategies have a potential to improve exhaust emissions specifically NOx, Particulate Matter, THCs, CO emissions and fuel economy.
