Abstract:
An engine management device for a combustion engine comprising:a sensor device for detecting variables indicative of engine load, the sensor device including a sensor arrangement having at least two sensors of a sensor set, the sensor set consisting of a mass air-flow sensor, an intake-air temperature sensor, an induction-pipe pressure sensor, and a throttle-valve position sensor; an engine load evaluator for determining the engine load on the basis of measured values supplied by the sensor device; and a throttle-valve position control loop including a throttle-valve position controller, a throttle-valve servo unit and a throttle-valve position sensor, the throttle-valve position controller producing a throttle-valve adjustment signal as a function of the determined engine load; the at least two sensors, the engine load evaluator and/or the throttle-valve position controller being microintegrated in a modular unit.
