Using an engine simulation code (WAVE) combined with statistical experimental design and optimisation techniques, the potential of a combined Miller cycle and internal EGR heavy duty engine for future truck applications (Euro 3 and 4) has been assessed. The practical issues related to a suitable variable valve timing or actuation system and boosting strategy have been considered. It is found that, whilst internal EGR levels suitable for future European emissions legislation cycles are possible, the boost pressures needed at high load to maintain a suitable air/fuel ratio when running a valve timing strategy to give acceptable levels of in-cylinder temperature (via the Miller system) are beyond the capabilities of current technology. It is believed, however, that such a system may still be suitable for application in markets which have duty cycles less dependent upon full load operation, for example Japan and, possibly, the USA.
