Abstract
One of the most important components affecting performance in internal combustion engines(ICE) is the intake manifold. The present work presents an improvement of Spark Ignition (SI) engine performance by adding a swirl generator (mixer) within the inlet port. Experiments were applied on a single-cylinder, four-stroke, GREEN CUT AV3500 gasoline engine. Exhaust emissions compositions and fuel consumption are recorded. To understand the behaviour of airflow through the intake port with and without the swirl generator, a 3D model was analysed using Computing Fluid Dynamic (CFD) by ANSYS Fluent 2020 R1. Results show an enhancement of engine performance especially fuel consumption by 24%, and the concentration of CO in exhaust emissions by 67%. As well as, computationally, pressure drop improved with intake port equipped with the mixer.
