Engine Speed Limitation

OPERATION
The Electronic Throttle Control (EML) control unit limits the engine speed by closing the throttle valve opening before reaching the limit speed of 6200 rpm. To avoid control problems between the EML and Digital Motor Electronic (DME) systems when limiting the engine speed, in the case of the DME control unit, the engine speed limitation is set to 6400 rpm. The EML control unit detects the engine speed by way of the engine speed signal (TD) from the DME control unit.
