    摘要： A basic target excess air factor tLAMBDA0 and a target fresh air intake amount tQac are set base upon the operation condition of an engine (30). A target excess air factor tLAMBDA is calculated by multiplying the ratio of a real fresh air intake amount rQac as detected by a sensor (16) and the target fresh air intake amount tQac by the basic target excess air factor tLAMBDA0. A fuel injector (9) is controlled so that the amount of fuel injected thereby converges to a target fuel injection amount tQf which corresponds to the target excess air factor tLAMBDA. It is possible to prevent variation of the output torque of the engine (30) accompanying a rich spike by this control, even if the basic target excess air factor tLAMBDA0 varies abruptly, since the fuel injection amount varies in correspondence to the variation of the real fresh air intake amount rQac.

    摘要： A control apparatus of an internal combustion engine is able to effectively suppress vibration occurring upon acceleration of a motor vehicle due to an increase in the torque generated by the engine. The apparatus controls the ignition timing in accordance with variations in the acceleration of the motor vehicle, so as to variably control the torque generated by the engine. Upon the start of variable torque control, a controller controls the opening amount of the throttle valve to be larger than the opening amount originally determined depending upon the current operating conditions of the engine. As a result, the generated torque is allowed to be larger than the normally generated torque during variable torque control, and vibration upon acceleration can be effectively suppressed.

    摘要： An electronic engine control system for a lean burn engine includes a unit for detecting an amount Qa of intake air fed into a cylinder of the engine, a unit for detecting an engine speed Ne, a unit for calculating a basic fuel injection pulse width TPbas on the basis of the intake air amount Qa and the engine speed Ne, and a unit for determining control parameters containing any of at least an air-fuel ratio, an ignition timing, a fuel injection timing, a throttle opening and an EGR rate in accordance with an operating state of the engine in optimum. A reference TPref having the same dimension as the basic fuel injection pulse width TPbas and which is a function of an accelerator operating amount determined on the basis of the accelerator operating amount is determined as a load parameter used upon determination of the control parameters of the engine in operation with a lean air-fuel ratio. Because the accelerator opening amount is inputted to calculate the reference .sub.Tpref so that the throttle opening is controlled, the measurement accuracy of the accelerator opening and throttle opening amounts can be ensured, particularly in a vicinity of the completely closed state of the throttle where the increasing rate of intake air to throttle opening exists.

    摘要： A method and an arrangement for controlling an internal combustion engine of a vehicle wherein a desired torque value is pregiven, this desired torque value being separated into at least two desired values. The desired values serve to adjust the charge of the internal combustion engine and at least one further power parameter, which effects a rapid torque change. The at least two desired values assume different values at least in one operating state.

    摘要： An apparatus for controlling operation of an engine is disclosed. The apparatus includes a passage for supplying air to the engine and a fuel injection valve. The engine burns air-fuel mixture to produce torque. A valve adjusts the quantity of air supplied to the engine. An ECU actuates the valve based on the driving state of the engine. The ECU feedback controls the air-fuel ratio by altering the position of the valve to prevent torque shocks caused by changes in the air supply. The feedback control employs two correction factors, the first of which is representative of the air-fuel ratio of the mixture, and the second of which is representative of an average deviation of the first factor from a stoichiometric air-fuel ratio value. The air-fuel ratio of the mixture is feedback controlled as a function of both correction factors.

    摘要： An apparatus for controlling idle speed of an engine is disclosed. The engine is able to perform stratified charge combustion and uniform charge combustion. A fuel injection valve directly injects fuel into the combustion chamber to perform either stratified charge combustion or uniform charge combustion in accordance with the running state of the engine. An automatic transmission is operably coupled to the engine to selectively load the engine. The engine power is increased for avoiding a decrease in the idle speed of the engine when the transmission starts to operate while the engine is idling. However, the power increase is delayed from when the transmission starts operating. The amount of fuel injected from a fuel injection valve is increased to increase power of the engine during stratified charge combustion. The amount of air supplied to the combustion chamber is increased to increase power of the engine during uniform charge combustion. The delay is longer during stratified charge combustion than during uniform charge combustion.

    摘要： In an apparatus for controlling a Diesel engine with exhaust gas recirculation and intake air throttling a control circuit is provided by which the intake air flow pressure is controlled by means determining the desired intake air pressure for intake air throttling operation. During operations utilizing charge air the charge air pressure is controlled by means determining a desired intake air pressure representing the sum of a desired engine operating point-dependent base pressure value and a desired supplemental pressure value which comprises the product of a desired supplemental raw pressure value which is dependent on engine speed and a fresh intake air mass flow control difference and a factor which depends on the opening degree of the exhaust gas recirculation control number.

    摘要： An ignition and mixture-forming apparatus and method for an internal combustion engine, wherein as a function of position, speed, or acceleration of an engine throttle displacement device measured by a sensor, and when the adjustment exceeds a preset value, a valve is opened to feed compressed air from a compressed-air accumulator to one or more cylinders of the engine, in addition to the intake air and the feed capacity of the fuel pump being increased, so that the filling of the cylinders with fuel/air mixture increases and the engine power thus increases. Another sensor prevents feeding of compressed air when engine speed has exceeded a preset upper limit.
