摘要： A fuel feed quantity control system of the so-called L-Jetronic system is described. The system is equipped with a Karman vortex air-flow sensor, at least one injector for feeding a fuel into an internal combustion engine, a controller for controlling the quantity of the fuel, which is to be injected, on the basis of intake air flow rate information from the air-flow sensor, and at least one operation parameter sensor. The controller also includes at least one additional control unit which serves to correct the quantity of the fuel, which is to be fed into the engine, in accordance with at least one operation parameter from the operation parameter sensor and frequency information outputted from the air-flow sensor. The quantity of the fuel, which has been determined based on an output from the air-flow sensor, is corrected by the controller in accordance with changes in kinematic viscosity of the atmospheric air.

摘要： A control apparatus of an internal combustion engine which has an air-fuel ratio adjusting device for adjusting the air-fuel ratio of an air-fuel mixture, and an ignition device for igniting the air-fuel mixture. When a knock sensor detects a knocking state of the engine, it delivers a knock signal corresponding to the detected knocking state. In response to the knock signal delivered from the knock sensor, first correction data, which instantaneously prevents the knocking state by changing to a high degree, and second correction data, which corresponds to the properties of fuel used and prevents the knocking state by changing to a low degree, are calculated. The ignition timing is set in accordance with the calculated first and second correction data, whereby the operation of the ignition device is controlled. The air-fuel ratio is set in accordance with at least one of the first and second correction data, whereby the operation of the air-fuel ratio adjusting device is controlled.

摘要： A method of detecting a fault of an exhaust gas recirculation system of an internal combustion engine, comprising detecting a temperature relating to a temperature of a gas recirculating through the exhaust gas recirculation system when the system is in a condition in which the system should be operated to return part of an exhaust gas of the engine to an intake passage, and detecting that the exhaust gas recirculation system is defective when the detected temperature is lower than a fault discriminating value. A condition of air to be sucked into the engine, such as intake air temperature and atmospheric pressure, is detected, and the fault discriminating value is set in accordance with the detected air condition, whereby abnormality or fault of the exhaust gas recirculation system can be detected accurately and reliably. Preferably, the fault detection is inhibited until the engine temperature reaches a predetermined value and/or a predetermined time period elapses after the start-up of the engine, whereby erroneous fault detection can be prevented.
