MOTORTECH MIC4 ignition controllers for MWM/DEUTZ Gas Engines



Based on the MIC4 series, MOTORTECH produces a special version as a replacement for the TEM-ZS1 and TEM-ZS3 ignition system use on MWM / DEUTZ gas engines. Designed as an Exchange device, the MIC4-ZS enables a quick conversion without great effort.

In addition to the MIC4-ZS ignition controller, the prepared conversion kits include the required high-performance ignition coils. Pre-chamber spark plugs or spark plug leads can be re-used, as these ignition coils have the same secondary connections as the original ones. The ignition coils-designed for MOTORTECH ignition controllers with MOST technology – guarantee the ideal performance support, especially when it comes to alternative combustibles with alternating or relatively low fuel value, e.g. biogas, mine gas, woodgas, sewage gas, landfill gas, etc.


MOTORTECH Spark plug leads for gas engines


PolyMot™ Spark Plug Leads

MOTORTECH’s PolyMot™ spark plug lead was globally patented in 1996. Since then more than one million leads were manufactured to this design. These spark plug leads are unique and offer several advantages when being compared to the genuine or aftermarket competition. With the knowledge gathered in ignition control and ignition coil research and manufacturing, a lot of the details were implemented into these products. The unique structure has achieved tremendous reliability records in the field.
