To detect knock, a piezoelectric knock sensor (basically a microphone) bolted to the engine block responds to unique frequencies caused by engine knock. The sensor generates a small voltage that is sent to the electronic control unit , which processes the signal to determine if, in fact, knock is occurring.
The objective of knock control strategies is to attempt to optimize the trade-off between protecting the engine from damaging knock events and maximizing the engine's output torque. Knock events are an independent random process. [8] It is impossible to design knock controllers in a deterministic platform. A single time history simulation or ...
General Motors’ next-generation dexos1 specification (Dexos 1 Gen 2), [7] released in 2015, included an engine test based on a GM 2.0-liter four-cylinder Ecotec that will test for LSPI. [8] The ILSAC GF-6 standard (released in 2020) also include a test for oil-related LSPI events in gasoline direct-injection engines based on a Ford 2.0 L four ...

A crank sensor (CKP) [1] [2] [3] is an electronic device used in an internal combustion engine, both petrol and diesel, to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters.
