Development of Hybrid Car such as EV, HEV, PHEV, is growing fast by focusing on exhaust gas and fuel efficiency due to fossil fuel depletion and reinforce of environmental regulation following by high oil price and global warming. However, there are some risks which shrink market share because of high price and low density of Energy. This is why RE-EV is focused as a new technology that expands mileage with pure-electronic energy which increases storage space with engine generating system.

RE-EV utilizes actuating-electronic-motor while regular driving. After rack of battery, it recharges with engine power generation system. There should be examination gradually that engine and generator’s selection of storage, design, manufacture, and exam analysis to improve fuel efficiency and RE-EV is power performance. Moreover, specialized-module for RE-EV is required to promote standard engine and generator. The paper analyzes engine performance by 4 types of case studies that changes inspiratory pressure and cylinder pressure by 1,500 to 3,500rpm with ETC location and Surge tank as exam variables. This analysis is based on phenomenon of decreasing inspiratory pressure in high rev through 2 cylinder- MPI type gasoline engine analysis. As a results, engine air flow could be expand by inetia and pulsation effect, when a intake pipe is short. In case of decreasing surface of U-tube, there is no inetia and pulsation effect due to fast air circulation in high rev. It also confirmed that pulsation effect mitigates during increasing surge tank’s volume. In comparison results of engine performance, all cases show improvement of generating power and torque. Torque reaches 2500rpm to 103.6Nm which is better than standard intake system over 11Nm. Generating power showed 3500rpm to 34.4kW also over approximately 4.7kW.
