Abstract
In the present work, the effect of hydrogen addition on the performance of a diesel engine has been studied. A quasi-dimensional multizone combustion model to simulate a four-stroke cycle of a diesel engine fueled with hydrogen-diesel mixture is developed. It is found that the addition of (12)% by mass of hydrogen causes an increase in the maximum (pressure, zonal temperature, and rate of heat release). This is due to increase in the rate of fuel mass burning, therefore, the time required to complete the combustion is reduced. In general, the addition of (10)% of hydrogen by mass gives a maximum improvement in the power and efficiency and a maximum reduction in specific fuel consumption (60)%.
