摘要： The ignition timing of an internal combustion engine is set to a fixed value if a predetermined signal is applied to a predetermined input terminal for servicing the ignition timing. However, if the engine is not in the idling condition, the ignition timing is controlled, as usual, depending upon the operating condition of the engine, even when the predetermined signal is applied to the service input terminal.

摘要： The ignition timing of an internal combustion engine is controlled to a fixed value during starting or for a period just after starting. However, if the engine is in a high-speed operating condition, the above control for fixing the ignition timing is interrupted and the ignition timing is controlled to change depending upon the change of the operating conditions of the engine.

摘要： An acceleration signal detector is provided for detecting an acceleration condition of an engine based on the open-and-close operation of a throttle valve. Switching arrangements associated with the throttle valve are provided for detecting the fully closed condition of the throttle valve and for detecting a partially closed condition of the throttle valve. Signal processing apparatus receives output signals from the switching arrangements, and a change in the output of the means for detecting a partially closed condition subsequent to a change in the output of the means for detecting the fully closed condition is indicative of acceleration. This arrangement eliminates erroneous signals that might otherwise be caused by chattering of switch contacts.

摘要： According to the present invention, an amount of fuel being supplied to an internal combustion engine during acceleration is controlled in association with a desired value of acceleration (a degree of acceleration) and a temperature of the engine. The amount of fuel being supplied increases, as the desired value of acceleration is increased, and as the engine temperature becomes lower. Thus, an engine output necessary for rapid acceleration is positively provided, with the assurance of a desirable driving feeling at slow acceleration.

摘要： The amount of fuel supplied to the engine is corrected in accordance with an air-fuel ratio correction coefficient. When the engine is in a predetermined first operating condition, the correction coefficient is calculated depending upon the detected concentration of a predetermined component in the exhaust gas, and thus the above correction is performed by closed-loop control. When the engine is not in the first operating condition, the correction coefficient is fixed, and thus the above correction is performed by open-loop control. An average value of the calculated correction coefficient is calculated only when the engine is in a predetermined second operating condition. An initial value of the air-fuel ratio correction coefficient when closed-loop control is resumed is determined to be the calculated average value.

摘要： In conventional electronic fuel injection systems, the flow rate of a fuel supply is fixed during a starting operation irrespective of time variations in the running parameters of an internal combustion engine. In accordance with the disclosed method and apparatus of the invention, however, the fuel supply flow rate is controlled in accordance with the time variations in the engine running parameters in the same manner as occurs after the starting operation, that is, during normal engine running operations, when at least one of the engine operating conditions of r.p.m. being higher than a preset level and flow rate of intake air being higher than a preset level is satisfied. Thus, the engine running operations either at a higher engine r.p.m. or at a higher intake air flow rate during the engine starting period can be stabilized while improving the engine startability and smoothing the engine running operations when an ignition switch is returned from its starting to its "on" position.
