摘要： An idling speed feedback control method for use with an internal combustion engine having electrical load equipment and a generator for supplying electric power to said electrical load equipment, said generator being driven by said engine, wherein an idling speed feedback control amount is effected as a function of the difference between an actual engine speed and a target idling speed. The method comprises the steps of detecting a generating state signal as a function of the field coil current of the generator which represents the generating state of the generator; detecting the actual engine speed; determining an electrical load correction value as a function of the generating state signal and the actual engine speed; and correcting the feedback control amount during idling by an amount corresponding to the correction value. Determining the electrical load correction value comprises modifying a reference correction value for a control amount, corresponding to a predetermined engine speed set on the basis of the detected generating state signal, as a function of the difference between the detected value of the actual engine speed and the predetermined engine speed.

The idling speed feedback control amount is effected as a function of the difference between an actual engine speed and a target idling speed. The method comprises the steps of detecting a generating state signal as a function of the field coil current of the generator which represents the generating state of the generator; detecting the actual engine speed; determining an electrical load correction value during a time period starting at or before the time when the electrical load correction value changes and ending at the time at or after the electrical load correction value changes. The electrical load correction value is then modified in accordance with the magnitude of the change and the idling speed feedback control is corrected as a function of the modified electrical load correction value.

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.

摘要： A deceleration fuel cut device adapted to interrupt the supply of fuel to an internal combustion engine when a detected actual engine rotational speed is higher than a predetermined value, and simultaneously a detected intake pipe pressure is lower than a predetermined value. The predetermined engine speed value is set to lower values as the detected actual engine temperature increases. The predetermined intake pipe pressure value is determined as a function of the detected actual engine speed. The predetermined intake pipe pressure value and/or the predetermined engine speed value may be set at different values between the time of initiation of cutting off the fuel supply and the time of termination of same, to impart a hysteresis characteristic to the fuel cut operation.

摘要： An internal combustion engine for a vehicle has an exhaust gas recirculating system for returning exhaust gases to the engine intake passage. The carburetion system for the engine includes a fuel enrichment valve. Sensors for various vehicle speeds and engine operating conditions operate control valves whose actions are modified by a sensor for atmospheric pressure, to control the fuel enrichment valve and a valve in the recirculation passage so that fuel enrichment and exhaust gas recirculation are both reduced when the vehicle travels at a high elevation having low atmospheric pressure.
