Abstract

In a system having an electronic controller for internal combustion engines, particularly injection engines in which the controller is functionally connected to a plurality of sensors and at least one actuator, the controller is part of an assembly which furthermore comprises a throttle-valve arrangement, an air-mass sensor and a throttle-valve position sensor. In systems with central injection, the injection valve can also be arranged within the assembly. By the compact structural unit thus obtained, cable connections are reduced to a minimum, so that, in their turn, reliability is increased and expense is saved. Furthermore, the arrangement facilitates maintenance and repair.
