    摘要: A control system employs a microcomputer, which controls the starting operation of a spark ignition type engine provided with a fuel injection system. The control system is loaded with, at least, contact information of an ignition switch for connecting an ignition device to a power supply and a starter switch for connecting a starter motor to the power supply, and an output signal of a temperature sensor for detecting the temperature of cooling water of the engine. Where the cooling water temperature is not higher than a predetermined temperature, a fuel pump which supplies pressurized fuel to an injector of the fuel injection system is started simultaneously with the closure of the ignition switch, and this fuel pump is stopped during the operation of the starter motor.

    摘要: A method of starting the operation of an internal combustion engine utilizes a turning force transmitted from wheels of a vehicle through a clutch in addition to a driving force generated by a starting motor. A computer for controlling engine operations detects the initiation of the engine starting operation on the basis of the rotating speed of the engine or intake air quantity and additionally detects the termination of the engine starting operation when the engine rotating speed or intake air quantity exceeds an associated reference value. When the engine stops in the course of running of a vehicle, the engine can be re-started under the influence of the inertial force of the vehicle without resorting to the operation of the starting motor.

    摘要: A learning map on which the rewriting of data is performed in accordance with the results of an internal combustion engine controlling operation is provided. When the number of pieces of data written in this learning map has become greater than one, the corresponding weighting is done for each unlearned region in the basis of the learning data on the learning already-learned regions, and the data in the already learned regions is written in unlearned region. The controlling of the engine is performed on the basis of the data written in the learning map.

    摘要: An engine power train control method and control apparatus for a vehicle having an engine and an automatic transmission is capable of quickly changing an air-fuel ratio to meet the requirements for exhaust gas without producing shocks and without reducing engine torque. An air-fuel ratio command value is varied stepwise for transition between an air-fuel ratio for lean-burn operation and a stoichiometric air-fuel ratio, and at the same time, the period following the completion of the stepwise variation of the air-fuel ratio command value, a basic fuel amount fed to the engine is varied stepwise from a value determined according to the air amount and an engine speed to a value determined according to a position of an accelerator pedal of the vehicle and the engine speed. In this way, shocks do not occur and the operability is improved, because the engine torque remains substantially constant through the air-fuel ratio transition.
