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 — ...

Detonation: A violent explosion; also called combustion knock. This usually occurs near the end of the combustion process when highly compressed, high-temperature end gases spontaneously ignite, ...

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, ...

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 ...

ISRO said the successful ignition of the pre-burner was a “major milestone” in the development of the engine. “This will be followed by development tests on the engine power head test article and ...

Aston Martin Lagonda Global has been granted a patent for a pre-combustion chamber assembly for spark ignition engines. The assembly aims to improve knock performance at high speeds and loads while ...

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.
