A control loop is permanently monitoring the signal of one or more knock sensors (commonly piezoelectric sensor which are able to translate vibrations into an electric signal). If the characteristic pressure peak of a knocking combustion is detected the ignition timing is retarded by steps of a few degrees.
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 result is an air mass request to achieve the torque requested by the ECM. The driver's requested torque can be higher than that requested by ECM when, for example: Maximum engine torque at the current operating point has already been attained; The traction control system (TCS) intervenes; the knock control system intervenes
The Trionic 5.2 and 5.5 systems utilized the manifold absolute pressure (MAP) sensor and the intake air charge temperature sensor to calculate the fuel injection curves, while the Trionic 7 and 8 systems are mass air flow type. Both systems have substantial differences that prevent utilization of components between the two.
[citation needed] The five-pin module was introduced in 1978 and was an early attempt at electronic timing control; it contains a provision for connecting a knock sensor. [ citation needed ] The seven- and eight-pin modules are used on early computer -controlled engines in conjunction with fixed-timing distributors, as the computer controls the ...
