An Investigation of the Effect of Air Filter Elements on Spark Ignition Engine Performance

Article Preview

Abstract:

This paper presents the results of an investigation on the effect of air filter elements on the performance of Spark Ignition (SI) engine. Three different types of material; paper, cotton and foam were tested as filtering element in the air filter before the mixing process with fuel in the carburettor. In the experiment, a four-stroke single-cylinder engine was coupled to a 20kW generator dynamometer to measure engine performance parameters; engine torque, engine power (B.P), brake thermal efficiency (BTE), brake specific fuel consumption (BSFC) and brake mean effective pressure (BMEP) at various engine speeds with maximum engine load. The results show correlation between engine performance and the qualities of filtered air as a function of type of air filter element/material used.
