1. Field of the Invention
The present invention relates to an internal combustion engine intake module, members thereof and electronically controlled throttle apparatus of a new car or similar products.
2. Description of the Prior Art
To ensure small size and compact configuration and to improve packaging density in the intake system of an internal combustion engine of a car, various techniques have been proposed to use synthetic resins for an intake manifold and a collector (surging tank), to mold them in an integrated form, and hence to incorporate a throttle valve, collector, intake manifold, injector and related parts into one module. The prior arts of internal combustion engine intake module are disclosed, for example, in the Japanese Application Patent Laid-Open Publication No. 03-202670, Japanese Application Patent Laid-Open Publication No. 06-81719, Japanese Application Patent Laid-Open Publication No. 07-301163, Japanese Application Patent Laid-Open Publication No. 07-83132, and Japanese Application Patent Laid-Open Publication No. 10-281026. In the Japanese Application Patent Laid-Open Publication No. 03-202670, it is shown that the collector and intake manifold are composed of synthetic resin, and the engine side of the intake manifold is made of metal. The Japanese Application Patent Laid-Open Publication No. 10-281026, it is revealed that the collector and intake manifold are composed of synthetic resin.
In any of the known examples, however, no reference is made to a specific relationship with an electronically controlled throttle apparatus connected to the collector.
