Abstract

The combustion process in an intemal combustion engine must be known in detail to find out the dependence of its operating conditions on the engines performance. This paper discusses a computer program that simulates the combustion processes of a two-stroke engine. The simulation includes modelling the heat transfers from the cylinder and crankcase, modelling the heat releases for gasoline and diesel engines, modelling the gas properties, modelling the energy balance, and modelling the flow coefficients through the ports. The performance of the two-stroke engine can be obtained from the simulation. As a case study, a two stroke MK1 engine was simulated and the simulation results the maximum indicated power is 18.3 hp at 5500 rpm and the maximum indicated mean effective pressure (IMEP) is 4.2 bar at 5000 rpm.

Abstract

A two-stroke engine is one of the commonly used energy conversion systems for transportation.The process inside the cylinder and the transport passages can be simulated with mathematical models with certain assumptions. In modeling and simulating a two-stroke engine, the flows in the passages are modeled as unsteady gas flows. The unsteady gas flows are important in a twostroke engine since they affect the intake and exhaust processes of the working fluid. The results of the simulation can be used for analyzing or tuning the intake and exhaust passages of a two-stroke engine. As an example, the program was applied for a two-stroke engine MK1.
