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： A torque detection mechanism can be provided for a power train and its control unit without newly adding a sensor and its signal processing module. As a gear pair for the torque detection mechanism of a phase difference type, existing gears in a transmission are used, or a gear pair for this mechanism are provided adjacent to these existing gears. From phase signals sent from pickups, a phase difference signal is obtained by use of one part of existing devices in the control unit. The torque detection mechanism can be realized with the minimum number of component parts by utilizing the existing members and spaces instead of newly adding a sensor and its module. The invention can be applied to either of FF and FR cars, and has a practical structure in respect of the performance, costs and reliability.

摘要： A method for feedback controlling air-fuel ratio of the mixture supplied to an internal combustion engine having a plurality of cylinders comprises the steps of, detecting respective air-fuel ratios of the exhaust gas from the respective cylinders with an air-fuel ratio sensor having a substantially linear output characteristic; calculating an average air-fuel ratio by using the latest detected air-fuel ratios of the respective cylinders; determining a fundamental feedback correction coefficient .beta..sub.0 for a cylinder of which air fuel ratio is feedback controlled next; retrieving a learning correction coefficient .beta..sub.1 for the cylinder of which air-fuel ratio is feedback controlled next from a learning map prepared by learning for the corresponding cylinder; and determining new learning correction coefficients .beta..sub.1 for the respective cylinders using respective deviations of the respective detected current air-fuel ratios from the latest average air-fuel ratio calculated in the previous step, whereby air-fuel ratio control at any desired air-fuel ratio is carried out with a high accuracy and with a uniform air-fuel ratio throughout the whole cylinders.

摘要： A method of electronically controlling the operation of an internal combustion engine is effected on the basis of results of arithmetic operations of digital control quantities derived from detected operating conditions of the engine through digital processing operations. The digital processing operations are subdivided into a number of tasks in dependence on the control functions to be performed. In addition, these tasks are subdivided into a plurality of priority levels. The memory has a task control block having run or execution flag areas in response to the priority levels and start request flag areas in response to the tasks, the start request flag areas being classified in accordance with the levels, in order to make it easy to correct, alter or add tasks. An order for starting the execution of the task is always controlled in accordance with the condition of the run flags and the start request flags.

摘要： A pressure responsive switch performing switching operation for converting pressure variations into electric variations is disclosed in which the actuating pressure of a snap switching member is adjusted by changing the contact pressure between a pressure applied member and the snap switching member which is in contact with the pressure-applied member. The gap between the break contact of the pressure responsive switch is adjusted thereby to adjust the difference between the pressure between the make contact of the switch when it is closed and the pressure between the break contact of the same when it is closed.

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 thermal time-delay switch comprises contacts which are normally engaged, a first bimetallic element associated with one of the contacts to separate the contacts from each other with temperature rise in the first bimetallic element, a second bimetallic element associated with the other of the contacts to bring the contacts into engagement with each other with a temperature rise in the second bimetallic element, and a heating resistor provided for each of the first and second bimetallic elements to heat it. The relative displacement between the contacts caused by the first bimetallic element with the temperature rise therein is larger than that caused by the second bimetallic element, so that the contacts are separated from each other substantially independent of voltage fluctuations over a wide range of a voltage source feeding the two heating resistors when the heating resistors have been connected to the voltage source for a given period of time.
