Fuel Injectors

Each fuel injector is independently controlled by the DME/Motronic control unit. This enables the control unit to precisely meter the injected fuel quantity and provides a faster response time during engine load changes. After engine has started (at about 600 RPM), fuel is injected into each specific cylinder at intervals of 120 degrees (crankshaft).

The DME/Motronic control unit can also turn off fuel injectors as part of its catalytic converter protection function. See IGNITION TIMING CONTROL under IGNITION SYSTEMS  for additional information.
