An Investigation of the Effect of 2T Oil Blend on Spark Ignition Engine Performance

Article Preview

Abstract:

This paper presents the results of an investigation on the effect of 2T oil blend on the performance of Spark Ignition (SI) engine. Three different types of 2T-oils; mineral oil, semi-synthetic oil and fully synthetic oil were tested according to blend ratio before the mixing process with fuel in the carburetor. In the experiment, a two-stroke single-cylinder engine was coupled to a 20 kW 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 performances and 2T-oil blended as a function of type of 2T-oils used.
