Computational Analysis of Flow Dynamics in a Four-Stroke Internal Combustion Engine

Abstract:

This paper presents a predictive investigation using CFD techniques focusing on the tradeoff between steady-state airflow considerations and unsteady transient pressure wave tuning of a single cylinder IC engine. An axisymmetric CFD model has been developed to initially examine the steady-state flow characteristics generated by different inlet entry radii. This has then been further developed to incorporate the unsteady, transient pressure wave effects caused by the motion of inlet valve and piston. Detailed simulation results, which are validated against experimental data provided by Group Lotus plc, are reported here and quantitative conclusions are drawn for maximising airflow in future inlet manifold design.
