Knock combustion is one of the primary factors limiting thermal efficiency improvement in
spark ignition (SI) engines. After a century of research, scholars have made significant …

Knock is one of the main limitations on increasing spark-ignition (SI) engine efficiency. This
has been known for at least 100 years, and it is still the case today. Knock occurs when …

Heat transfer to the walls of the combustion chamber is increased by engine knock. In this
study the influence of knock onset and knock intensity on the heat flux is investigated by …

Improving vehicle fuel economy is a central part of efforts toward achieving a sustainable
society. An effective way for accomplishing this aim is to enhance the engine thermal …

In enhancing the performance of automotive internal combustion engines, increasing the
compression ratio offers an effective means of improving engine thermal efficiency. If the …

This paper presents a measurement technique to visualize the distribution of the in-cylinder
mixture temperature and an experimental approach for analyzing the effect of the …

Downsizing or higher compression ratio of SI engines is an appropriate way to achieve
considerable improvements of part load fuel efficiency. As the compression ratio directly …

The effect of characteristic cycle-to-cycle variations on knock in gasoline engines is not yet
fully understood. The analysis requires the use of experimental techniques to characterize …

A methodology has been developed to determine, for every cycle on which significant knock
is detected, the area in which self-ignition occurs. This methodology is based on the …

An experimental investigation on the spatial distribution of knock events in a turbocharged
spark-ignition engine for hybrid vehicle applications was conducted by using a multichannel …
