TL;DR: In this article, a downsized spark engine with different methanol-isooctane blends was simulated and the authors obtained the pressure and temperature evolution profiles of these mixtures during knocking were obtained and showed that knock originated from the intensive interaction between pressure wave and the heat released from auto ignition.
22 citations
TL;DR: In this paper, the effects of what mechanism that promots and inhibits low-alcohols effects on auto-ignition characteristics of iso-octane is studied based on detailed chemical kinetics mechanisms.
18 citations
TL;DR: In this paper, a new reduced mechanism for n-butanol combustion simulation under engine conditions was developed based on the direct relationship graph with error propagation (DRGEP), sensitivity analysis and entropy production analysis methods.
17 citations
TL;DR: In this article, a numerical model of exergy analysis for low-temperature combustion engine was established, and the exergy items were further calculated to explore the effect of different intake conditions on exergy destruction in LTC process.
17 citations
TL;DR: In this paper, the effects of methanol/iso-octane and ethanol/iso octane blends on knock behavior were investigated under a known knocking condition with the mixing proportion of 10% and 30% from the analysis of temperature, fuel consumption rate, heat release rate and pressure rise rate.
