The code is logged. Background InformationDetonation sensors are on the upper cylinder block between every two cylinders. Each sensor monitors two adjacent cylinders. For example, one sensor monitors cylinders 1 and 3 and one sensor monitors cylinders 2 and 4.
Illustration 1 g03845561The Integrated Sensing Module (ISM) supplies 8 VDC to power the sensors. The detonation sensors provide electrical signals to the module that indicate mechanical engine vibrations. Each sensor outputs an electrical signal. The signal is amplified and the signal is filtered. The frequency of the signal corresponds to the mechanical frequency of the vibrations. The amplitude of the signal is proportional to the intensity of the vibrations.The ISM monitors the signals to determine the presence and the severity of the detonation. The ISM can retard the timing of the cylinders to limit detonation levels. The timing may be retarded for a single cylinder or for more than one cylinder. The timing may be retarded for all the cylinders, if necessary. If retardation of the timing does not sufficiently limit the detonation, the ISM will shut down the engine.An ISM can retard timing by as few as three degrees for light detonation levels. The timing can be retarded up to six degrees for severe detonation. For most applications, the minimum allowable actual timing is ten degrees BTC (five degrees BTC for propane operation). A proportional strategy is used for advancing the timing after the timing has been retarded. The rate of advance is based upon the level of detonation. The rate is faster for lighter detonation. The fastest
