The authors have been undertaking theoretical and experimental studies to reduce the specific fuel consumption of diesel engines. These studies are:<BR>1) Improvement of cycle efficiency through the variation of parameters involved in the high pressure cycle related to the combustion process, and in the low pressure cycle related to the intake and exhaust process, including the turbocharger system.<BR>2) Improvement of mechanical efficiency through the reduction of friction and other losses. As a result of these studies, the “E-Series” engines were developed which have a specific fuel consumption that is 7-15% lower than that of the conventional engines.<BR>Further studies were conducted to increase the thermal efficiency of the “E-Type” engine using simulation. The results indicate the possibility of reducing the specific fuel consumption by an additional 7%.
