つた。 Electronic fuel injection devices (EGI, EFI, etc.) are conventionally known as devices of this type. In this fuel injection system, the control device is installed inside the vehicle. Many of the various input sensors such as air flow sensors, pressure sensors, intake temperature sensors, water temperature sensors, throttle opening sensors, O 2 sensors or idle switches, and various actuators such as fuel injection valves are used to detect the operating status of the engine. It is installed in the engine room. Therefore, electrical wiring is required between the various input sensors in the engine room and the control device in the vehicle, and between the control device and the various loads in the engine room, and the trouble and cost required for this wiring and the wiring space are problems. Furthermore, in recent years, as a large number of in-vehicle electronic devices have been installed in the same vehicle, it has become difficult to secure a place to install a control device. Furthermore, when control devices are made smaller in order to save installation space, there is a drawback that the heat of the control circuit cannot be adequately treated.

Moreover, by using the heat of vaporization of the fuel to cool the control device, it is possible to achieve higher integration, improve the reliability of the device, and promote fuel atomization to obtain a more uniform air-fuel mixture. The purpose is to provide an engine control device that can

In the figure, 1 is an air cleaner, 2 is a fuel pressure regulator disposed within a housing 4 of a mixing body 3, 5 is a fuel injector attached to the regulator 2, and 6 is a throttle valve. 7 is an engine control device, 8 is a pressure sensor provided in the casing 9 of this control device 7, 10 is a throttle opening sensor, 11 is an idle switch, 12 is a cooling water temperature sensor, and 13 is a
It is an O2 sensor. That is, the control device 7 calculates the basic fuel amount of the engine based on the information of the pressure sensor 8 and the information of the engine rotation speed,
Correction calculations are performed based on information from the cooling water temperature sensor 12, O 2 sensor 13, throttle opening sensor 10, idle switch 11, and other various sensors 15, thereby supplying the necessary fuel from the injector 5 to the engine 14. . Further, 16a is the intake side of the engine, and 16b is the exhaust side. Reference numeral 17 denotes a heat sink for the control device 7, which is disposed inside the mixing body 3 in the intake passage. Thereby, the heat of the fuel injected from the injector 5 promotes atomization, and at the same time, the heat sink 17 is cooled by the heat of vaporization of the fuel.

Since this is carried out effectively, high integration, miniaturization, and reliability can be achieved. Furthermore, since fuel atomization can be promoted, a more uniform air-fuel mixture can be obtained.
