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 ...

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 ...

A simple set-up for quick and purely electrical QC testing of knock sensors is described in this paper. The main goal is to measure the "impedance" frequency response function of the sensors. The ...

In vehicles equipped with knock sensors, it can be difficult to determine the octane number requirement according to the current Coordinating Research Council E-15 procedure which is based on ...
