摘要： The invention provides an output torque control method and apparatus for a lean burn internal combustion engine which accounts for aging of component parts, and in which no stepwise change of torque or shock occur when an air fuel ratio is changed. The method and apparatus according to the invention control an intake air amount while maintaining an emission purification function by controlling the air fuel ratio to that of a theoretical mixture (air fuel ratio of 14.7) in a case where a limit NOx emission is determined by using a detected air fuel ratio and lean burn operation becomes difficult due to the amount of NOx emissions. Abrupt change of an output torque when the air fuel ratio is changed is curtailed by controlling a fuel amount or an air amount after calculating the fuel amount or the air amount from an engine speed and an accelerator depression angle.

摘要： In a valve control apparatus for an automobile, an H-bridge type chopper main circuit 4 is operated by a control signal PWM from a microcomputer 1 to thereby drive a motor 9 for controlling a throttle valve 10. The power element current from the chopper main circuit 4 is detected by a shunt resistor 5 in the form of a voltage, and the detected voltage is amplified by an amplifier 6 and then taken into the microcomputer 1 through a sample hold circuit 12 and an A/D converter. The sample hold circuit 12 is operated in synchronism with the control signal PWM from the microcomputer 1. Further, the A/D converter is also operated in synchronism with the control signal PWM from the microcomputer 1. The motor 9 is controlled by a throttle valve opening angle command and a throttle valve opening angle signal, and further the motor 9 is controlled by a detected motor current.

摘要： A method and apparatus for detecting the quality of combustion in each cylinder of a multi-cylinder internal combustion engine is disclosed. The invention determines a combustion stroke of each cylinder by sensors and detects the rotational speed of the engine at least three times during each combustion stroke by a rotation speed calculation device. The detected rotational speeds are evaluated by an arithmetic calculation device to identify the variation in rotational speed of each piston during a combustion stroke whereby the quality of combustion is, thus, determined. In a feature of the invention fluctuations in rotational speed caused by reciprocating inertia (.omega..sub.c) are calculated and eliminated from fluctuation in engine speed caused by combustion (.omega..sub.g) so that the quality of combustion based only upon variation in detected speeds caused by combustion is derived.

摘要： A fuel injection apparatus in accordance with the invention has a hot wire type sensor disposed in a bypass air passage and adapted to sense the flow rate of air in the bypass air passage. In order to absorb the pulsation of air flowing in the bypass air passage, the bypass air passage opens at its one end to the air cleaner of an intake system disposed in a portion upstream from the hot wire sensor. An orifice is disposed in a portion of the bypass air passage downstream from the hot wire sensor.

摘要： In an acceleration pump of a carburetor for an internal combustion engine including a cylinder and a piston reciprocatorily inserted in the cylinder, the piston is formed in its upper portion with a transverse bore for a stopper member to extend therethrough to be urged by a heat sensitive element to move in a direction at right angles to the direction of reciprocatory movement of the piston, so that additional fuel for acceleration can be supplied to the engine in a quantity which is accurately corrected to accommodate itself to changes in ambient temperature, by means of the heat sensitive element. The transverse bore is formed at its top wall and bottom wall with projections, and the stopper member is formed at its upper surface and lower surface with depressed portions, so as to enable the lengths of the downward and upward strokes of the piston to be controlled in accordance with changes in ambient temperature. Thus the acceleration pump is capable of supplying to the engine additional fuel for acceleration in a quantity which is corrected to accommodate itself for changes in ambient temperature.
