| Abstract | ||||
| Today, studying the parameters that affected on the gasoline engine performance becomes very important for the popular using of this type of engines. In spite of the previous studies concerning the economic fuel consumption, some aspects still need more investigations. There are many investigations concerning the internal combustion engine performance. In previous researches the effect of valve timing on engine performance and detonation were studied. In this work, the effect of changing exhaust back pressure with variable intake valve timing on the engine performance was theoretically studied. It was found that the fuel consumption decreased and engine performance improved. The validity of the simulation technique was checked by comparing its results with those from experimental results then a good agreement was noticed. | ||||
