    Abstract: Intake port is an important part of the gasoline engine, its structure will influence the gas flow characteristics which directly affects the performance of the engine [1]. In this paper, three-dimensional CFD calculation and structural optimization were used to research the performance of gasoline engine. “Theoretical modeling of combustion characteristics and performance parameters of biodiesel in DI diesel engine with variable compression ratio” International Journal Of Energy And Environment, Volume 4, Issue 2, pp [8] Peter L. Mtui, “Performance And Emissions Modeling of Natural Gas Dual Fuelling Of Large.

    The complexity of the three-dimensional turbulent unsteady and compressible flow in internal combustion engines suggests that the experimental programme should involve the investigation of one parameter at a time and initially make use of simplified flow arrangements. A versatile test rig was built for this purpose and allows both pressure drop. Abstract. While engineering applications of the large eddy simulation (LES) technique are becoming a common reality in many branches of engineering and science, its application to engine flows has lagged behind due to the relatively more complex nature of both the flow and the geometry relevant to in Cited by:
