  • Patent number: 6283101
    Abstract: The invention relates to a method for controlling exhaust gas recirculation in an internal combustion engine. Known methods provide for a control unit which generally controls the exhaust gas recirculation rate via a throttle and a stop valve in accordance with operating parameters of the internal combustion engine. No further information is provided on these operating parameters. The invention provides for a method and a device for controlling exhaust gas recirculation in an internal combustion engine which method and device are able to take into consideration a wide range of operating conditions of an internal combustion engine. To this end the control unit comprises a basic characteristic map (1) above the parameters “rotation per mite of international combustion engine” and “quantity of fuel supplied per operating cycle”. The basic signals of the basic characteristic map (1) can be influenced by correcting units which can be connected as needed and transmit correcting signals.

  • Patent number: 5390639
    Abstract: A method of calculating fuel injection quantities, as determined by the initiation and duration of fuel injection, in an internal combustion engine in response to repetitive engine operating parameters measured during engine operation. The quantity of fuel injected into a cylinder of a multicylinder engine may be determined through measurement of an operating characteristic of that cylinder immediately prior to injection. The timing of injection may also be responsive to the measurement of the engine operating characteristic which may not be uniformly repetitive.
