Ignition

Ignition Coil (R50)

Function
In the case of static high-tension ignition distribution, two ignition coils are fitted in one module. Each of these ignition coils has two secondary voltage outputs and thus supplies the ignition voltage for two cylinders. The coils work according to the ignition redundancy principle, which means that ignition takes place in these two cylinders at the same time. One spark plug ignites during the compression stroke and the other during the throw-out stroke.

Installation Location
The ignition coils are located in the middle of the cylinder head.

Failure
If one coil fails, either the motor cannot be started or poor idling characteristics are the consequence. The misfires can cause the MIL to light up.
