Abstract: An intake device for a multi-cylinder engine includes an intake manifold, an intercooler, and a heat insulation member. The intake manifold has an intercooler housing that is a cylindrical body formed from a resin material and internally accommodates the intercooler; and an intake air distributor that is a cylindrical body formed of a metal material and has one opening connected to one opening of the intercooler housing, the intake air distributor distributing an intake air. The heat insulation member is interposed between another opening of the intake air distributor and the cylinder head in the multi-cylinder engine.

Abstract: Disclosed is an intake apparatus for an engine transversely mounted within an engine compartment at a front of a vehicle. The intake apparatus comprises: an intake manifold made of a synthetic resin and disposed on a front side of the engine, the engine front side being a front side of the vehicle; and a fuel distribution pipe disposed between the engine and the intake manifold to extend in the cylinder row direction and capable of delivering fuel to respective cylinders of the engine; wherein the intake manifold has a protruding portion provided on a front surface thereof to protrude from the front surface in a vehicle forward direction, wherein the protruding portion is provided at a position capable of allowing a member disposed in front of the intake manifold to come into collision therewith in the event of a vehicle frontal collision.

Abstract: An intake system for an engine is provided. The system includes a chamber room formed in an intermediate section of an intake passage, an intercooler disposed inside the chamber room, an intake air inlet chamber formed in a part of the chamber room upstream of the intercooler, an introducing portion for introducing intake air into the intake air inlet chamber, and a baffle plate dividing the intake air inlet chamber into an upstream space communicating with the introducing portion and a downstream space communicating to the introducing portion via the upstream space. When the engine is in a low engine load operation, the intake air mainly flows through the upstream space to an intercooler side via the baffle plate, and when the engine is in a high engine load operation, the intake air flows through the upstream and downstream spaces to the intercooler side via the baffle plate.

Abstract: An intake device of an engine comprises an intake manifold of a four-cylinder inline engine and a water-cooling type of intercooler. The intake manifold includes a downstream branch pipe portion connecting to cylinders, a chamber portion connecting to the downstream branch pipe portion, and an upstream intake pipe portion connecting to the chamber portion. A rectangular opening portion having a vertically-long shape is formed at the upstream intake pipe portion. The intercooler includes an intercooler body portion having a pair of faces which has the widest face-area and faces to each other in an engine width direction. The intercooler body portion is installed in the chamber portion, by being inserted through the rectangular opening portion, so as to divide an inside of the chamber portion into two parts in the engine width direction thereby.
