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

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.
