Detcon
There are 2 types of Detonation Controllers:-
DetCon 2 - for up to 2 sensors
DetCon 20 - for up to 20 sensors
Detonation control system
The function of the DetCon detonation control system is to prevent the engine from damages caused by knocking combustion. Vibration occurs in the engine compartment during the combustion process. These have a frequency which is characteristic for the engine type. The DetCon measures the vibratory energy within a narrow frequency range which is typical for the respective engine. The energy measured is proportional to the knocking level. Measurement is only carried out within operating cycles in which combustion is possible. This increases the sensitivity of the measurement and minimizes its reaction to random noises. Depending on the application, the operating cycles are determined using either an ignition sensor unit (ISU) or a camshaft sensor.
Applications
The DetCon Dentonation Control System can analyze two-stroke and four-stroke engines with up to 20 cylinders and up to a maximum 1 kHz ignition frequency. The device is avaliable in two versions: – DetCon2 for two knocking sensors – DetCon20 for up to 20 knocking sensors Both device types are available as a built-in device for a control cabinet or with a CSA certified housing. The following manual applies to both device types. Any differences between the two versions are clearly identified. In order to define the time frame for potential knocking, the detonation control system must know the ignition timing of the first cylinder in the firing sequence. Depending on the application and the ignition controller used, this can be determined in different ways: – Standard application for gas engines: using an ignition sensor unit (ISU) connected between the ignition output and the ignition coil of the first cylinder – Diesel and pilot injection engines: using an inductive camshaft sensor – When using the ignition controller MIC850: no additional sensor required, the signal is transmitted via the auxiliary synchronization output (ASO) .
