Knocking combustion research is crucially important because it determines engine
durability, fuel consumption, and power density, as well as noise and emission performance …

Cool flames play a critical role in ignition timing, burning rate, burning limits, engine
knocking, and emissions in conventional and advanced combustion engines. This paper …

The present work investigates the accuracy of laminar flame speeds measured from
outwardly propagating spherical flames. We focus on methane/air mixtures at normal …

Low-temperature flames such as cool flames, warm flames, double flames, and auto-ignition
assisted flames play a critical role in the performance of advanced engines and fuel design …

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 …

The laminar flame speed sl is an important reference quantity for characterising and
modelling combustion. Experimental measurements of laminar flame speed require the …

Many direct numerical simulations of spherical hot spot auto-ignitions, with different fuels,
have identified different auto-ignitive regimes. These range from benign auto-ignition, with …

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 …

Ammonia has attracted much attention because of its carbon-free nature. Ammonia also has
a high research octane number (RON), making it a promising anti-knock additive for …

As promising alternatives to fossil fuels, hydrogen (H 2) and syngas are playing important
roles in the development and control of high-efficiency, low-emission engines. Achieving …
