Modelling and Simulation of Methanol and Diesel Fuelled HCCI Engine for Improved Performance and Emission Characteristics

Suraj Randive, Dhananjay Thombare

Abstract: Alcohol fuels are widely used for HCCI engine. In this study, Methanol is used in single cylinder engine as a premixed fuel with diesel in different compositions. Engine performance will improve in terms of thermal efficiency and emission. Intake charge within temperature range of 1200-1400c gives good results for combustion, heat release & pressure rise rate. Intake charge temperature and engine speed are dominant parameter which affects the performance and emission of the engine. Higher thermal efficiency & lower emission can be achieved optimizing combustion duration and injection timing of both fuels which is also helpful for extending the operating range of HCCI engine.
