摘要： A fuel injection control system for an internal combustion engine which can eliminate lean misfiring and rich misfiring at asynchronous injection and exhausting of non-combustioned HC. When the asynchronous injection is performed at engine cranking or at acceleration, a judgement is made as to whether the injected fuel will be divided by closure of an intake valve. When division is not detected, fuel injection is performed in normal manner. When division is detected, rate of the fuel division is computed. As a result of computation, fuel injection is performed when judgement is made that a predetermined amount of the injected fuel will be introduced into the cylinder. Furthermore, the amount of fuel not introduced into the cylinder is computed to reduce a corresponding amount from a fuel injection amount for the next cycle. On the other hand, when judgement is made that the predetermined amount of fuel will not be introduced into the cylinder, fuel injection does not take place.

摘要： A device for controlling fuel injection of an internal combustion engine which is capable of preventing the A/F ratio from becoming over-rich immediately after the engine is started to decrease the emission of hydrocarbons. An intake pipe is connected to a four-cylinder spark ignition-type gasoline engine, and an injector for injecting fuel is disposed in the intake pipe for each of the cylinders of the engine. An electronic control unit (ECU) controls fuel injection through the injector in an amount corresponding to the running condition of the engine. When the number of revolutions of the engine reaches a predetermined value (e.g., 500 to 1000 rpm), the ECU judges that complete combustion has occurred and then decreases the amount of fuel injected through the injector during a period in which the amount of fuel adhered to the wall surfaces is excessive.

摘要： A system for controlling the air-fuel ratio in which the amount of fuel injected into the engine is controlled in accordance with the flow rate of air passing through an air intake pipe including a throttle valve for introducing the air into the engine and the engine operating conditions. A bypass of the air intake pipe is opened or closed to change the air-fuel ratio of the mixture to slightly richer and leaner sides of a basic air-fuel ratio, and the change of the engine output conditions based on the change of the air-fuel ratio is used to correct the air-fuel ratio in an optimum direction. On the basis of a parameter indicating the engine operating conditions such as the detection value of the intake pipe pressure, a control is made to introduce the air which passed through the bypass to one of the upstream or downstream portion of the throttle valve.

摘要： An electronically-controlled fuel injection system includes electromagnetic fuel injection valves each of which is mounted in each cylinder of an internal combustion engine, and the injection of fuel during the starting period of the engine is also effected only by these fuel injection valves. During the starting period of the engine, the duration of the opening of the fuel injection valves is controlled at a constant value irrespective of the rotational speed of the engine until the rotational speed reaches a value corresponding to the initial combustion of fuel in the engine, after which the duration of the opening of the fuel injection valves is controlled in relation to the rotational speed of the engine. Further, during the time that the starter motor is in operation, the duration of the opening of the fuel injection valves which was basically determined in the previously mentioned manner is increased to a great extent in accordance with the temperature of the engine until the engine rotational speed reaches a value corresponding to the complete combustion of fuel in the engine.

摘要： A lubricating apparatus for an internal-combustion engine comprises a detector for detecting whether the engine runs or not, a heat storage reservoir connected to lubricating oil outflow and inflow ports of the engine by a circular pipe system for storing the oil and maintaining its temperature, the heat storage reservoir being provided outside the engine, a hydraulic pump provided between the inflow port and the heat storage reservoir for controlling the supply of the oil stored in the heat storage reservoir to portions of the engine in response to a control signal, and a controller responsive to an output of the detector for producing the control signal to stop the hydraulic pump in order to maintain a temperature of the oil stored in the heat storage reservoir when the detector detects a stop of the engine and for producing the control signal to actuate the hydraulic pump to supply the oil, whose temperature is maintained by the heat storage reservoir, to the portions of the engine. The restarting of the engine is easily made because the oil is collected in the heat storage reservoir when the engine is stopped. In addition, the size of the engine is decreased, because the oil pan is omitted or part of the oil pan remains in the engine.

摘要： A relation with output characteristic of an oxygen density sensor corresponding to a deviation of an air fuel ratio of a mixed gas supplied actually to an internal combustion engine from a desired air fuel ratio is stored beforehand in an air fuel ratio controller of the present invention. Then, the air fuel ratio deviation is computed correspondingly to an actual output of the oxygen density sensor according to the stored relation, and an air fuel ratio controlled variable is corrected according to the computed air fuel ratio deviation, thereby controlling the air fuel ratio to the desired air fuel ratio. Further, a change in output characteristic of the oxygen density sensor to the air fuel ratio is detected, then the output characteristic of the oxygen density sensor stored beforehand is corrected according to the detection result, and thus if the output characteristic of the oxygen density sensor fluctuates due to a deterioration arising on the oxygen density sensor, the air fuel ratio controlled variable will be decided in consideration of the fluctuation.

摘要： A gas sensor of constant-current type is used to detect a gas component in exhaust gases from an internal combustion engine so as to perform feedback control of air/fuel ratio of an air-fuel mixture supplied to the engine. In order to detect an air/fuel ratio which is richer than a stoichiometric value, a voltage applied to the gas sensor is set to a high value so that the gas sensor does not exhibit a constant-current characteristic. In the case it is desired to detect an air/fuel ratio which is either richer or leaner than the stoichiometric value, the voltage may be changed between the high value and a lower value at which the gas sensor exhibits a constant-current characteristic. Engine parameters are detected to determine whether the engine requires a rich mixture or a lean mixture, and the voltage may be changed as the result of such determination. An output current of the gas sensor is detected to ascertain air/fuel ratio so that air/fuel ratio is controlled to a desired value suitable for engine operating condition.
