  • Method for recognizing the power stroke of a cylinder of an internal combustion engine
    Patent number: 4889094
    Abstract: A method for recognition of the power stroke of an internal combustion engine is proposed, in which recognition as to whether a cylinder is currently in the power stroke is possible by means of camparison of a signal that is synchronous with the crankshaft angle and a signal that is modulated by the combustion events of the engine.

  • Control system for an extrinsic-ignition internal combustion engine responsive to an engine load signal provided to dual control units
    Patent number: 4762105
    Abstract: A first control unit of a multiple function control system for a motor vehicle engine controls a function, such as fuel injection, for which it is desirable to provide an engine load signal measured by the amount of air drawn or forced into the engine per unit of time, determined by what is generally known as an air quantity meter. A second control unit of the control system controls the timing of an electrical ignition system for which it has been conventional to supply an engine load signal derived from a pressure transducer.
