したシ、配管が脱落する危険性があった。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, the Senna installed in the engine room has its own complicated electronic circuit, such as the Boost Senna and Airf Senna.
The arrangement between the fuel injection device! It was necessary to install a nozzle countermeasure circuit in each control circuit to prevent the occurrence of a 1Kil conducting nozzle), and a constant voltage circuit had to be installed in both as well, which meant that 6 extra circuits were required. ! pl! In addition, there was a drawback that the voltage accuracy of both the nozzle countermeasure circuit and the constant voltage circuit had to be managed at the same time. In addition, the piping between the pressure sensor and the engine intake manifold was connected from the outside using a rubber tube, which required a lot of work and there was a risk that the piping would fall off.

理も片側外だけですむ。The various sensors that indicate the operating status of the engine are located near the control device 7, so they can be connected with short wiring, which simplifies wiring and reduces the influence of induced noise. can do. In addition, since the pressure sensor 8 for controlling the basic fuel amount of the engine is also integrated into the control device 7 and housed in the same casing 9, the constant voltage power supply circuit required for the pressure sensor 8F can also be shared, allowing new installation. i) There is nothing to do. In addition, not only is the conventionally necessary external wiring between the control device 7 and the pressure sensor 8 unnecessary, but also the filter circuit can be omitted since external noise and radio interference induced in the external wiring can be prevented. . Furthermore, voltage accuracy management, which was required in the case of conventional separate power supplies, only needs to be done on one side.
