Spray angles strategies in a heavy-duty diesel engine with reactivity controlled compression ignition (RCCI) combustion

Mahbod Armin1 Amir Hossein Ghobadi2

Abstract :
Reactivity controlled compression ignition (RCCI) is a combustion strategy in bi-fuel vehicles that improves ignition and reduces emissions without a need for fundamental modifications in the engine design. Numerous parameters affect the performance and emission of the engine in the combustion phase of RCCI, including the injection angle. The present study attempts to investigate the performance and emission of an engine as a result of a change in the injection angle and, hence, to evaluate the effect of this parameter. The geometry of a heavy diesel engine has been used in this research for the experiment and numerical simulations. The impact of the injection angle has been studied numerically via CFD and using the SAGE combustion model. The results indicate that a larger injection angle delays the combustion. Therefore, the injection angle can be considered a major design factor affecting the emission of heat in the combustion phase.

Keywords : reactivity controlled compression ignition combustion fuel injection angle natural gas emission
