PID - Pre Ignition Detection

PID Spark Plug Adaptors

Modern combustion techniques with its increasingly higher charged engines show pronounced shifts of the ignition point which means the mixture remains longer at a higher thermal level. The result is a higher tendency towards pre ignition.

With the new pre ignition detector COMBI PID SMETEC delivers a simple to use tool to quickly determine the pre ignition boundaries. Based on the ion-current measurement technique this system uses the regular built in spark plug. Automatic test-routines shift the ignition point to determine if the combustion was initiated by the spark or by pre-ignition. Besides the optimisation of the combustion process it is possible to determine the heat value of spark plugs
