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 ...

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.

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 ...

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 ...

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 ...

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 ...

The majority of car manufacturers are currently spending most of their research funding on battery tech and fancy touch interfaces, but Ferrari still holds the internal combustion engine (ICE) close ...

Dyno tuning is great. But, a dyno-tuned engine can't always be tuned for the stress it might see on the street, let alone something like the continued abuse of, say, a track day. This is especially ...

There are a million and one things that could go wrong with a car engine. In old times, it was solely up to the owner and/or technician to drudge through possible issues until they determined what was ...
