Intake temperature sensor, water temperature sensor, throttle wJt sensor,
Many of various input sensors such as an Ot sensor or an idle switch and various actuators such as a fuel injection valve are installed in the engine room. For this reason, a lot of electrical wiring is required between the various input sensors in the engine room and the control device in the car, and between the control device and each pole load in the engine room, and the time and cost required for this wiring, as well as the wiring switch, are problems. Ta. 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 mounting location for the control device. Furthermore, when the control device is downsized in order to save mounting swivels, there is a drawback that the heat of the control circuit cannot be adequately handled.

提供することを目的としている。This invention was made to eliminate the drawbacks of the conventional ones as mentioned above, and by making the control device itself highly integrated and making it possible to install it in the engine room, it can be effectively wired with various human power sensors. Moreover, by using the heat of vaporization of the fuel to cool the control device, it can be highly integrated.
Another object of the present invention is to provide an engine control device that can improve the reliability of the device and promote atomization of fuel to obtain a more uniform air-fuel mixture.
