One-Dimensional and Three-Dimensional Modeling of Dynamic Fluid Flows in a Four-Stroke Multi-Cylinder Spark-Ignition Engine

This project’s focus is high-performance engine design for a small displacement four-stroke, single-cylinder, spark-ignition engine. Computer models are developed to simulate the complex fluid flows found within air-restricted, high performance internal combustion engines. These simulation results are used in component design studies to optimize engine volumetric efficiency. Engine fluid flows are simulated with Ricardo Software’s WAVE 1D and VECTIS 3D engine flow modeling programs.  The work will investigate the effect of intake geometry and volume after the air-inlet restrictor on performance by optimizing volumetric efficiency.

In conjunction, exhaust geometry will be developed as the exhaust’s performance also impacts the overall volumetric efficiency. This initial research will help form a basic understanding of engine design intended to be implemented with validation testing in Summer 2011.
