るため故障が多くコストも高いという欠点があった。Conventionally, as an example of a device that increases the idling speed when the air conditioner is turned on,
A device according to No. 50 is known, which detects the engine speed and cooling water temperature and automatically increases the idling speed according to the cooling water temperature, depending on the engine condition. However, once the engine has warmed up and the temperature inside the car exceeds the set temperature and the air conditioner is turned on, the idling speed will always be controlled to a constant increase. As a result, if the temperature inside the car is relatively low and the load on the air conditioner is J times, the idling speed will be forced to rise more than necessary, which will worsen fuel efficiency. was there. Further, since the idling rotational speed tfflJ fnl is determined mechanically using negative pressure, there is a drawback that there are many failures and the cost is high.

り達成される。In view of the above points, the present invention improves fuel efficiency, reduces malfunctions, and reduces costs by increasing the idling speed according to the temperature inside the vehicle when the air conditioner is turned on in a fuel-priority type electronically controlled fuel supply system. The purpose of this invention is to provide a method for controlling the idling speed of an automobile equipped with an air conditioner, in which the air flow rate to be supplied to the engine is actuated by a computer based on information on each engine ridge. In a fuel-priority type electronically controlled fuel supply system that is configured to perform air-fuel ratio control by controlling an actuator, the system detects the temperature inside the vehicle when the air conditioner is turned on, and increases the set idling speed according to the detected temperature inside the vehicle. This is achieved by an idling speed control method characterized in that the idling rotation speed is increased.

センサーである。The present invention will be described below with reference to an embodiment shown in the drawings.
In FIG. 1, 10 is an engine, 12 is a throttle valve, 14 is a throttle valve actuator, and 16 is a throttle valve.
18 is a fuel injection device; 20 is an accelerator pedal; 22 is a position sensor for the accelerator pedal 20;
4 is a pressure sensor that detects the pressure upstream of the throttle valve 12; 16. The pressure sensor 28 for detecting the pressure downstream of the LD throttle valve 12 is a computer, and the above configuration is similar to the conventional fuel priority type electronically controlled fuel supply system disclosed in, for example, Japanese Unexamined Patent Publication No. 57-91343. 30 is an air conditioner, and 32 is a room temperature sensor that detects the temperature inside the vehicle.

時間毎に繰返し行なわれるようになっている。When the engine is turned ON, the temperature T inside the vehicle is detected by the room temperature sensor 32, and the idling speed 1 is set based on the temperature T inside the vehicle as shown in FIG. Ru. In this case, for example, TI is set to 23°C, T2 is set to 30°C, and I(+ is set to 600 rpm
■' is set to 1000 rpm. In this way, control is performed so that the set idling rotational speed becomes the set idling speed ■. In addition, the standard idling rotation speed is 1. Alternatively, the set idling rotation speed (2) can be controlled by controlling the amount of fuel to be supplied to the engine 10 by the computer 28, and controlling the air-fuel ratio by adjusting the air flow rate to 1 in accordance with this. Ru. This completes the suppression of the idling speed, but this starts again when the air conditioner 30 is turned on or when the room temperature changes, or is repeated at regular intervals. ing.

性が高い等、極めて効果的である。As described above, according to the present invention, the fuel priority type electronically controlled fuel supply system is maintained as it is, but by changing the computer software, the electronically controlled fuel supply system can adjust the temperature inside the vehicle when the air conditioner is turned on. Since the set idling speed is increased according to the detected temperature inside the car using “Since it is not controlled and can be raised appropriately according to the temperature inside the car, fuel efficiency is improved, and since no special equipment is required for this purpose, there is almost no increase in cost. It is extremely effective with few failures and high reliability.
