Abstract

A sensor arrangement and engine management device for a combustion engine, the engine management device including the sensor arrangement for detecting variables indicative of engine load, a mechanism for determining engine load on the basis of measured values supplied by the sensor, as well as a throttle-valve position control loop. At least two of the sensors of the sensor arrangement, which may include a mass air-flow sensor, an intake-air temperature sensor, an induction-pipe pressure sensor, and a throttle-valve position sensor, are microintegrated in a modular unit. The engine management device is made such that a sensor device with the at least two sensors, the mechanism for determining, engine load and/or the throttle-valve position controller used in the throttle-valve position control loop are microintegrated in a modular unit. The engine management device can be used, for example, for controlling a spark ignition engine in a motor vehicle.
