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, ...

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 ...

For a variety of reasons, race engines can experience either or both these conditions involving uncontrolled combustion. And, we all know either or both can cause power losses and potentially damaged ...

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 ...

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.
