Fuel Injection

One output stage drives 3 injector valves. The injection cycle is therefore divided into groups (semi-sequential injection). This also ensures restricted engine operation in the event of failure of one group. At a speed of 600-800 RPM, fuel is injected only once per 720 degree crankshaft angle into one cylinder group. This facilitates precise metering of the quantity of fuel since the injector valves need not be actuated so often. Parallel injection (activation of all injector valves simultaneously) as in the DME M1.2 system is no longer possible.
