摘要： An engine idle and speed control arrangement incorporating a butterfly-type throttle valve. The throttle valve is disposed so that it is at a relatively small angle to a plane containing the throttle valve axis and extending perpendicular to the direction of air flow through the induction passage. The peripheral edge of the throttle valve is configured so as to avoid binding. Bypass idle air flow is provided around the throttle valve as to provide substantially the entire idle air speed requirements of the engine. This arrangement permits better idle control since the idle air-flow changes will be more uniform in response to given angular changes in the position of the throttle valve.

摘要： Electronic engine control systems have a plurality of individual components on the intake tube, some of them located relatively far from one another. For electrically connecting the individual components to the electronic control unit, relatively long electric connecting lines and a relatively large number of plug connections are therefore necessary. This invention sets forth a preassembled throttle apparatus which includes at least one throttle device, rotatably accommodated in a throttle valve support, and an idling adjuster in a housing; the throttle apparatus has a bypass conduit, which bypasses the throttle device and which can be varied by the idling adjuster, into which a regeneration valve can output fuel, the regeneration valve being triggerable by an electronic control unit that is also accommodated in the housing. The throttle apparatus of the invention is intended particularly for mixture-compressing internal combustion engines with externally supplied ignition.

摘要： An engine-controlling atmospheric pressure detection system which is capable of detecting atmospheric pressure highly frequently, even during descending, based on a signal from a pressure sensor for detecting air-intake pressure. An actual air-intake pressure is normalized in relation to air-intake pressures at high and low altitudes, respectively, when a throttle valve is closed, which pressures have been stored in a ROM, thereby determining the resultant value as a parameter. The atmospheric pressure is thus detected from the minimum value of such a parameter.

摘要： In an engine induction system, a drive frequency f1 of an ISC valve 13 for duty control and a characteristic frequency f2 of an intake passage between an air cleaner 8 and a throttle valve 11 are set so as to obtain a relationship: (3/4)f1.ltoreq.f2.ltoreq.(5/4)f1. In this set system, a resonance chamber 17 is connected to the intake passage between the air cleaner 8 and the throttle valve 11 to thereby deaden the vibration caused by the driving of the ISC valve 13. Accordingly, the engine induction system is allowed to prevent the amplification of the vibration accompanying the actuation of the ISC valve so as to prevent the deterioration of the detection accuracy of an airflow meter while being allowed to meet requirements such as an improvement in the responsiveness when the ISC valve disposed in an ISC pipe is duty controlled.

摘要： A fuel injection device increases an increment value of fuel after cut-off of assist air so that the air/fuel ratio for combustion can be held constant to stabilize the idling rotational speed. The device has control means for controlling, based on various detection signals indicative of an engine cooling water temperature, an engine rotational speed, an amount of intake air, etc., a valve-opening time of a fuel injection valve in accordance with a predetermined control program, and also controlling an on/off control valve for cutting off air supplied to fuel atomizing means. Fuel incrementing means increases an amount of liquid fuel supplied to the fuel injection valve depending on opening/closing of the on/off control valve and the temperature of engine cooling water. When the on/off control valve is closed and an engine is in a state of steady operation, the increment value of the liquid fuel supplied to the fuel injection valve can be gradually increased by the fuel incrementing means.

摘要： A bypass air flow rate control apparatus has an idle speed control valve for continuously adjusting an air flow rate and an on-off control valve for allowing and shutting off an air flow passing therethrough. When an atmospheric pressure sensor detects that the atmospheric pressure is lower than a predetermined value, in other words, the density of intake air is lower than a predetermined value, the on-off control valve and the idle speed control valve are switched over. The air flows through the on-off control valve by an amount corresponding to the air flow rate reduced in the idle speed control valve. The valve switching over operation is performed when one of the following three conditions is satisfied: the engine is generating no torque, in other words, the engine is in a fuel cut operation; a load larger than a predetermined load value is applied; and the engine is accelerated at a rate equal to or greater than a predetermined value. In the latter two conditions, a large torque is generated by the engine. As a result, a torque variation due to the air flow rate variation upon the valve switch over is restrained, so that the vehicle shock which gives a driver a feeling of uneasiness can be relieved and the drivability can be improved.
