Methanol is a promising fuel to suppress knock for improving engine compression ratio. In
this study, knock combustion was simulated in a downsized spark engine with different …

Abstract Negative Temperature Coefficient (NTC) behavior is an essential feature of low-
temperature oxidation for large hydrocarbon fuels, which is of particular relevance to cool …

It is generally accepted that knock in spark ignition engines might be caused by end-gas
autoignition. However, the detailed mechanism for autoignition-induced pressure oscillation …

The four-stroke spark-ignition (SI) internal combustion engine has good fuel economy and
high power/weight ratio, making it very suitable for small aircraft. Normally, four-stroke …

The cycle-to-cycle variation in the knock intensity is commonly encountered under abnormal
combustion conditions. The severity of these abnormal combustion events can vary …

Experimental and computational investigations are carried out to identify the generalized
criterion to predict the preignition tendency of methanol and ethanol mixtures in shock tubes …

Using one-dimensional numerical simulation, the interactions of flame propagation, auto-
ignition and pressure wave during various knocking combustion scenarios are …

The main objective of this work is to comprehensively provide a fundamental understanding
of the entire process of the flame-pressure wave interactions with end-gas autoignition and …

This study aims to evaluate the performance, emissions, and combustion characteristics of a
methanol/natural gas dual-fuel spark-ignition engine by conducting several experiments. A …

In gasoline direct-injection engines, in-cylinder flow plays an important role in terms of fuel
atomization, mixture, turbulence, combustion, and emission. The in-cylinder flow is affected …
