【考案の詳細な説明】
本考案は電子制御式燃料噴射装置付（以下EFI
エンジンと称する）の吸気系、特にその加熱装置
に関する。[Detailed explanation of the invention] This invention is equipped with an electronically controlled fuel injection system (hereinafter referred to as EFI).
The present invention relates to the intake system of an engine (referred to as an engine), and particularly to its heating device.
EFIエンジンにおいて、吸入空気制御を行なう
スロツトルボデイには一般に寒冷地でのアイシン

であつた。 On the other hand, the air valve, which bypasses the throttle valve and increases the amount of intake air when the engine warms up, and plays the role of a fast idle mechanism, uses heat transfer from the engine's cooling water temperature and is activated by a bimetal and electric heater. Although the amount of intake air is adjusted, if proper fast idle function cannot be achieved due to insufficient heat transfer, the function can be achieved by separately passing hot water around the electric heater (coil). ing. However, in this case, it goes without saying that two independent hot water heating parts are required for the throttle body and the air valve coil, and therefore heating piping using bypass paths from the water pump to each hot water heating part is required. It was hot.

A throttle body 1 with a built-in air valve 2 is integrated with an air valve 2 sandwiching a single heating water channel 5. As a result, the throttle body 1 and the air valve 2 are heated simultaneously by heated water (arrow) such as engine cooling water passing through the common passage 5. Furthermore, 3 and 4
1 shows a throttle position sensor and a throttle lever that are respectively attached to the throttle body. Reference numerals 6 and 7 indicate bypass air passages (white arrows), and as is well known, when the air valve 2 is actuated, the intake air flowing through the throttle body 1 is routed to a surge tank (not shown) through these bypass passages 6 and 7. It is intended to supply increased amounts directly to

効な水温加熱ができる。 As described above, according to the present invention, by integrating the throttle body and the air valve so that they are in contact with a common heating water channel, it is possible to shorten the heating hot water path of the intake system, reduce costs, and reduce weight. . Furthermore, as mentioned above, in the conventional type having two or more separate water temperature heating parts (for example, an additional water temperature heating part for the idle speed controller), the water temperature increases as you go downstream of the waterway. There was a fear that sufficient heating temperature could not be obtained in the heating section located on the downstream side due to the drop in temperature.However, according to the present invention, this inconvenience has been resolved and an effective heating section with less temperature loss has been created. Water temperature can be heated.
