Numerical analysis of the dual fuel IC engine working cycle

Abstract

Vehicle represents the part of people everyday life. However, because massive usage of IC engines, as the drive train, for which adequate replacement it was not found till today, have caused prognoses about oil disappearing. This have produced necessity to find some alternative, or more accurate other fuel for usage. One of the ways for fuel consumption reducing is application of dual fuel engines, where one part of fossil fuel will be replaced with some alternative fuel. In this paper, numerical analysis of the working cycle, for gasoline engine was conducted, by application of ANSYS software package. As the fuel it is defined the combination of gasoline and CNG, in proportions of 25% of gasoline and 75% of CNG. Results analysis was performed based on obtained cylinder pressure.
