An internal combustion engine intake module, members thereof and electronically controlled throttle apparatus for a car and related products characterized by great strength, and light weight and compact configuration wherein the weight of the electronically controlled throttle apparatus and motor to be connected is reduced. The internal combustion engine intake module of the present invention comprises a collector, an electronically controlled throttle body connected to the collector, and a plurality of intake manifolds connected in parallel integrally with the collector. It is characterized in that the collector is bent upward on the side of the electronically controlled throttle body, and a motor for driving the electronically controlled throttle is provided on the body integrally with the inner side of the bent side. It is further characterized in that the intake manifolds are made of synthetic resin containing a fiber or aluminum group alloy casting.

Internal module, members of the module, and electronic controlled throttle device for internal combustion engine

An intake manifold and a collector made of synthetic resin are molded integrally to constitute a body of an intake module. A synthetic resin holder for holding at least one of a harness and a piping member (a pipe for hot water, and a canister purge pipe) is mounted at the upper part of the intake module body to incorporate the harness and/or piping member as an intake module element. Further, an engine control unit, an injector, a throttle body and so on are also incorporated into the module body to progress formation of an intake system of the internal combustion engine into module, and module elements are increased more than that presented previously to further enhance simplicity of vehicle assembling work, convenience of transportation, and mounting density, and to realize smaller and lighter weight, housing properties, and lower resistance of harness.
