The automotive industries are recently developing hybrid electric vehicle (HEV) to meet future fuel economy and emission regulation, combining two propulsion systems, mostly using an internal combustion engine and an electric motor. A HEV has the advantage of improving fuel economy and reducing exhaust gas using a high efficiency operation together with the assistance of an electric motor. Diesel engines used in the HEV are inherently more efficient compared to gasoline engines and, therefore, have a higher fuel economy. Besides it has the advantage of lower CO2 emission. A lot of research is carried out most to incorporate diesel engine technology in a HEV. Furthermore, the recent development of high pressure injection systems and turbocharger systems for diesel engines enables more reduction of emissions and improvement of fuel consumption. In this study, conventional diesel vehicle, parallel diesel HEV, and improved parallel diesel HEV are composed and optimized to compare fuel economy, performance, and emission. A one-dimensional engine analysis tool, WAVE, was used with a 2.7L diesel engine. ADVISOR, designed for rapid analysis of the performance and fuel economy of vehicle models, was used for a conventional and hybrid electric vehicle by applying output data from WAVE as the input engine data file for ADVISOR. A parallel diesel HEV shows at least 34~71% better fuel economy and improved acceleration ability than a conventional diesel vehicle. The improved diesel HEV is about 0.5~3% better fuel economy than the parallel diesel HEV. The energy loss of the parallel diesel HEV is 23~28% less than the conventional vehicle by the regeneration.
