摘要： A fuel supply control method for internal combustion engines, which is capable of stabilizing the engine rotational speed to a desired idling speed immediately after the rotational speed of the engine at idle suddenly changes due to an external disturbance such as a change in the electrical load on the engine. The fuel quantity to be supplied to the engine is determined in accordance with operating conditions of the engine in the idling condition, and the determined fuel quantity is corrected by a correction value which is determined in response to the difference between a desired idling speed of the rotational speed of the engine and an actual value thereof. When the absolute value of a detected rate of change in the rotational speed of the engine is larger than a predetermined value, the correction value is corrected to thereby correct the determined fuel quantity.

摘要： A method of controlling fuel supply to an internal combustion engine, wherein a quantity of fuel for supply to the engine is determined by correcting a basic value of the quantity of fuel determined as a function of at least one operating parameter of the engine by correction values dependent upon operating conditions of the engine, and the determined quantity of fuel is supplied to the engine. A value of at least one predetermined operating parameter of the engine is detected. A single voltage creating means is adjusted to set an output voltage therefrom to a desired value. Predetermined one of the correction values has a value thereof set as a function of the output voltage from the voltage creating means and dependent upon the value of the at least one predetermined operating parameter of the engine. Determined is a value of the predetermined one correction value corresponding to the detected value of the at least one predetermined operating parameter of the engine and to the set desired value of output voltage of the single voltage creating means. Preferably, the at least one predetermined operating parameter of the engine includes the rotational speed of the engine, and intake pipe absolute pressure thereof.

摘要： An ignition timing control method for an internal combustion engine, which controls the ignition timing of a mixture to be supplied to the engine in a feedback manner responsive to the difference between the actual engine speed and the desired idling speed. When it is determined that the engine is in a predetermined idling region and the engine temperature is above a predetermined value, the ignition timing is retarded by a predetermined amount, and the ignition timing thus retarded is corrected by a correction value calculated by multiplying the difference between the actual engine speed and the desired idling speed by a predetermined coefficient, to thereby control the ignition timing to the ignition timing value thus corrected. The ignition timing feedback control is inhibited when the voltage at a predetermined input terminal of a central processing unit is at a predetermined input level.

摘要： A method for controlling the flow rate of supplementary air supplied to an internal combustion engine via at least one supplementary air passage bypassing a throttle valve arranged in the intake air passage, by means of at least one control valve arranged across the at lease one supplementary air passage. The valve opening of the control valve is decreased with a decrease in the engine rotational speed, when the throttle valve is detected to be in a substantially fully closed position and at the same time the engine rotational speed is higher than a predetermined value which is higher than an idling speed of the engine. Preferably, the at least one supplementary air passage comprises a plurality of air passages, and the at least one control valve comprises a plurality of on-off valves arranged across respective ones of the air passages. One or more of the on-off valves are selectively opened in response to the extent of engine warming-up and/or an increase in engine load.

摘要： A valve operating system in an internal combustion engine includes a cam shaft provided with a valve operating cam, a rocker arm having a pair of support wall portions which are integrally connected at their base ends to a swinging support portion swingably supported on a support member mounted on a cylinder head and which are opposed to each other at a distance in a direction along the swinging axis of the swinging support portion, a support shaft supported between the support wall portions, and a roller which is rotatably supported on the support shaft with a bearing interposed therebetween so as to be in rolling contact with the valve operating cam. A lower connecting wall interconnecting lower portions of the base ends of the support wall portions is projectingly provided on the swinging support portion in a manner opposed to an outer peripheral surface of a lower portion of the roller. Thus, it is possible to increase the rigidity of the rocker arm, while avoiding an increase in size of the rocker arm.

摘要： A method of selectively and automatically adapting an electronic control unit for internal combustion engines, depending upon whether the engine has a manual or an automatic transmission. When the engine has the manual transmission, a first signal indicative of a shift lever position assumed by the manual transmission is always generated. When the engine has the automatic transmission, a second signal indicative of the shift lever position is generated when the automatic transmission assumes a neutral position or a parking position, and the first signal is generated when the automatic transmission assumes a position other than the neutral position or the parking position. When it is determined that the second signal is being generated, second control data is selected to control the operation of the engine, and when it is determined that the first signal is being generated and at the same time the starter is operating, first control data is selected to control the engine operation.

摘要： A method of detecting the opening of a throttle valve in a fully closed position in an internal combustion engine. A first predetermined opening value larger than the minimum opening value of the throttle value determined by structural factors is stored as an initial value of a fully closed position-discriminating variable, while a second predetermined opening value smaller than the minimum opening value is stored as an initial value of a stored opening value of the throttle valve in the fully closed position detected by a throttle valve opening sensor. The fully closed position-discriminating variable is updated or set to a newly detected throttle valve opening value when the latter is smaller than the former. Then, the stored opening value of the fully closed throttle valve is updated or set to the thus updated fully closed position-discriminating variable when the latter continues to be substantially equal to throttle valve opening values subsequently detected over a predetermined period of time after the updating of the fully closed position-discriminating variable has been carried out.

摘要： A fuel injection control method for successively injecting fuel into a plurality of cylinders of an internal combustion engine in predetermined sequence in synchronism with pulses from top-dead-center detecting means which are successively generated immediately after generation of each pulse from cylinder-discriminating means. The method is adapted to perform a fail safe function in the event of occurrence of an abnormality in the cylinder-discriminating means. The number of pulses is counted which are successively generated from the top-dead-center detecting means immediately after generation of each pulse from the cylinder-discriminating means. If no further pulse from the cylinder-discriminating means is detected until the count of pulses from the top-dead-center detecting means reaches a number equal to the sum of the number of the engine cylinders and while the rotational speed of the engine is higher than a predetermined value, the cylinder-discriminating means is regarded as abnormal. Then, injection of fuel into the cylinders is effected in the above predetermined sequence in synchronism with pulses from the top-dead-center detecting means alone, irrespective of generation of subsequent pulses from the cylinder-discriminating means.
