Abstract
Continuous Variable Valve Timing System or CVVT has a duty of variation of continuous open timing of the valves. This system has been put on the intake camshaft in EF7 engine. In this article, thermodynamic analysis of variation for open selective angles of valve according to variation of engine speed and load has been investigated. Opening angles in two state of gas and gasoline fuel by selecting of best point on the basis of data results of engine test has been achieved and this article analyses of the cause of this selection from thermodynamic point of view.
