Because the energy crisis and environmental pollution are significant concern, a next-generation combustion mode for internal combustion engines that can simultaneously reduce exhaust emissions and substantially improve thermal efficiency has attracted increasing attention. In the last two decades, diesel-fueled HCCI (homogenous charge compression ignition) combustion has been widely researched. It has been determined that diesel HCCI combustion has the potential to improve NOx and soot emissions at low-to-medium loads; however, it suffers from higher HC (hydrocarbon)/CO (carbon monoxide) emissions, narrow operating ranges, and uncontrollable ignition timing and combustion rates due to low volatility and high ignitability. For this reason, 30%–50% (v/v, briefly G30, G40, and G50) gasoline/diesel fuel blends are used in a novel technology of a compound HCCI combustion mode, in which port fuel injection and in-cylinder direct injection are combined. The combustion and emission characteristics of the compound HCCI combustion using blend fuels are investigated on a single-cylinder engine. The effect of the gasoline volume in the blends, the premixed ratio, and the overall fuel supply rate on compound HCCI combustion are initially evaluated, and the effects of the intake air boost on G30 compound HCCI combustion is also investigated.
