ANOVA analysis of hydrogen-fuelled compression ignition engine for sustainable mobility

Compression ignition engine plays a significant role in transportation because of their excellent performance and high thermal efficiency. Compression ignition engines recently received much criticism due to their harmful environmental emissions and high dependability on conventional fossil fuels. Hydrogen as fuel in CI engine can save its existence and bring back its popularity with minor modifications. It can also reduce emissions, which contribute to global warming and perform much more efficiently than diesel engines. In present work numerical investigation of the performance of the hydrogen-fuelled compression ignition engine has been done to find out the optimum compression ratio and engine load for maximum break thermal efficiency (BTHE). A range of compression ratio (CR) from 12 to 18 and engine loading from 0 to 12 kg are selected as the key parameters for ANOVA. The Quadratic model of the response surface method is considered for optimization. The optimized BTHE of hydrogen-fueled engine is observed as 29.62%, at the compression ratio of 14.2 and engine load of 10.2 kg. The optimized brake specific fuel consumption (BSFC) of hydrogen-fueled engine is observed as 0.262 kg/kW-hr, at the compression ratio of 14.2 and engine load of 5.4 kg.
