Engine knock is the sharp, metallic sound that cuts through the hum of a healthy engine. At its core, engine knock is a problem of timing. In a knocking engine, parts of the air-fuel mixture don't ...

In a study published in Combustion and Flame, researchers investigated the impact of non-thermal reaction chemistry on the propagation of combustion fronts for a H 2-CH 4 fuel mixture burning in air ...

Knock sensors are devices used in internal combustion engines to detect engine knock or detonation. The knock sensor detects vibrations and sends a signal to the engine control module (ECM), to ...
