Abstract

In this current work, the outcome of four sets of spark timings on engine performance parameters is studied. CFD simulations are carried out on a variable compression ratio twin spark SI engine for both methanol and gasoline. Simulations were able to predict performance parameters with high accuracy. To simulate flow physics, combustion in the engine, ANSYS Fluent is employed. A parametric study of the effect of spark timing and compression ratio under methanol operation at 1600 RPM is performed. The results yield a promising strategy in deciding spark advance angle. Both methanol and gasoline show increased mean effective pressure at twin spark of 26°–28° BTDC.
