Engine Modeling & Simulation to Correct Operational Issues with a Lean Burn Two-Stroke Engine
This paper is divided into two parts. The first part addresses why we have a need for advanced computer modeling, which will discussthe issues facing the large bore engine and why the solutions are neither simple nor straight forward and why additional science needs to be utilized. In the second part, the paper describes how computer modeling of the air induction and exhaust system can be used to determine issues with existing components that affect combustion stability and overall engine reliability. Areas that are investigated include the intake manifold, exhaust manifold, internal air chest, ports, port timing and turbocharger match. The software model can then be used to validate design changes or optimize specific design criteria to achieve the desired result.
