TL;DR: In this paper, the effect of the gasoline volume in the blends, the premixed ratio, and the overall fuel supply rate on compound HCCI combustion was evaluated, and also the effects of the intake air boost on G30 compound HCI combustion were also investigated.

TL;DR: In this article, the authors proposed a dual-fuel sequential combustion (DFSC) on a single-cylinder engine, which introduces a well-mixed, lean fuel/air mixture into the cylinder by injecting high-cetane number fuel (n -heptane was used in this study) at the intake port followed by the direct injection of a high-octane number (ethanol, iso-propanol, 1-butanol and iso-Octane) near the top dead center (TDC).

TL;DR: In this paper, the authors discussed the heat release mode and its effect on combustion characteristics of stratified charge compression ignition (SCCI) combustion with a two-stage fuel supply.

TL;DR: In this paper, the authors investigated the auto-ignition mechanism, combustion process, and emissions characteristics of n-butanol in active-thermal atmospheres, and found that the autoignition of nbutanol can be classified into three modes, namely, thermal atmosphere combustion, active atmosphere combustion and active thermal combustion, depending on in-cylinder gas temperature and radical concentrations just before injection.

TL;DR: In this paper, the ignition delay times of n-butanol/n-heptane mixtures were measured using a rapid compression machine at compressed pressures of 15, 20, and 30 bar, in the compressed temperature range of 650-830 K, and with equivalence ratios of 0.4, 1.0, and 1.5.
