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 ...
I recently got asked about what "pinging" is, and what the difference is between pre-ignition and detonation, what causes it, and why it is bad for an engine. Basically, both pre-ignition and ...
Pinging—that sound that resembles pebbles being thrown on a tin roof—has become familiar to all of us as a common occurance with today's low-octane fuel and reduced engine speeds. Call it pinging, ...

Understanding the precursor to detonation: Probing high-pressure deflagration with laser ignition experiments
Suddenly, there's a flash of intense light and heat, followed by a rapidly expanding fireball. Combustion of high explosives is everywhere in popular culture, and it's also critical for ensuring the ...
Russia has demonstrated a pulse-detonation engine (PDE) with low-energy ignition and a specific impulse of 800s in static conditions, about half that of comparable hydrocarbon-fuelled ramjet at Mach 2 ...
