TL;DR: In this article, a comprehensive review on the latest research progress, including the particulate matter formation mechanism of gasoline engines, effects of fuel/air mixture preparation strategies, fuel physical-chemical properties, and engine operating conditions on particulate size distribution characteristics, and the effects of the driving cycle on vehicle particulate emissions were summarized.

TL;DR: In this article, the authors present an experimental study on the combustion and emissions characteristics of RCCI (reactivity controlled compression ignition) combustion in which in-cylinder direct injection of n-heptane combined with port injection of ethanol and gasoline, respectively, are used with a singlecylinder engine.

TL;DR: In this paper, the authors present an experimental study on combustion and emissions characteristics of reactivity controlled compression ignition (RCCI) combustion in which in-cylinder directly injected n-heptane combined with port injection (PI) of ethanol, n-butanol and n-amyl alcohol are used in a singlecylinder engine and the results show that when the overall lower heating values (LHVs) per-cycle is constant, with the increase of premixed ratio (RP), nitrogen oxides (NOx) and soot emissions decrease.

TL;DR: In this paper, the effects of injection timing and premixed ratio on the combustion and emissions characteristics of Reactivity Controlled Compression Ignition (RCCI) combustion with n-heptane/gasoline-like fuels are investigated on a singlecylinder engine.

TL;DR: In this paper, the effects of different injection pressures and injection timings on the combustion and emissions of the surrogate fuels were investigated, and the results were compared with those of a commercial gasoline with an octane number of 95.
