Abstract:
A comparison between throttled and unthrottled spark ignition combustion with residual enhanced HCCI combustion is made. Early intake valve closing and late intake valve closing valve strategies for unthrottled spark ignition combustion are evaluated and compared. Approximately 3-6 percent relative improvement in net indicated efficiency is seen when comparing unthrottled spark ignition combustion with throttled spark ignition combustion depending on valve strategy and engine speed. The relative improvement in efficiency from spark ignition combustion to HCCI combustion is approximately 20 percent for the conditions presented in this study. The rebreathing strategies have the highest efficiency of the cases in this study.
