Like much in life, the difference between detonation and pre-ignition, and their effects, comes down to timing. Both refer to a situation when an engine's fuel/air mixture combusts at the wrong time, ...

Under the necessary conditions of ignition and proper burn rates (cylinder pressure history), both these conditions can exist in virtually any engine. But, in particular, they certainly apply to race ...

Dr. Vickey Kalaskar and the SwRI team have pioneered a groundbreaking testing methodology to tackle stochastic pre-ignition (SPI) in heavy-duty hydrogen-fueled engines (H2-ICEs). SAN ANTONIO — ...

Southwest Research Institute and The University of Texas at San Antonio are collaborating to develop methods to detect pre-ignitions in real-time. The researchers will first use laboratory-grade ...

THE experiments on the frictional electrification of sand described by E. W. B. Gill 1 are of interest in respect of the pre-ignition and combustion knock generally observed when hydrogen is used as ...

A collaboration in the US aims to create a detection system that can identify pre-ignition in hydrogen internal combustion engines (H2-ICE). The Connect project brings together a multidisciplinary ...

When your car starts making a metallic knocking sound under the hood, you'd assume it could only be one thing: the engine. However, there are two common culprits, and they're definitely not the same.
