Abstract

A synthetic resin intake manifold having a space formed between a surge tank and each of rise pipe parts in side view, comprising the surge tank and plurality of intake pipes each having the rise pipe part connected to the lower part of the surge tank and extending upward and disposed parallel with each other, wherein the surge tank (20) is formed so as to have a tank main part (20a) extending along the disposing direction (28) of the intake pipes (21A to 21D) and opposed to the rise pipe parts (29A to 29D) of the intake pipes (21A to 21D) and a side expanded part (20b) provided between a pair of rise pipe parts (29B, 29C) expanding from the middle part of the tank main part (20a) along the disposing direction (28) and disposed in the middle part along the disposing direction (28) in order to allow the capacity of the surge tank to increase while avoiding the size therefore from increasing, and the inner ends of the pair of spaces (38) formed on both sides of the side expanded part (20b) between the rise pipe parts (29A to 29D) and the tank main part (20a) are closed by both side walls of the side expanded part (20b).

Description

technical field [0001] The present invention relates to an intake manifold having a surge tank formed by joining a plurality of joining members made of synthetic resin and disposed on the side of an engine body, and a plurality of intake pipes arranged in parallel. The plurality of intake pipes respectively have a vertical pipe portion connected to the lower part of the buffer tank on the opposite side of the engine main body and extending upward. A space is formed between the buffer tank and each standpipe. Background technique [0002] Existing intake manifolds of this kind are known to the public, for example, in Japanese Patent Laid-Open Publication No. 10-299591. In this prior art, the buffer tank is formed to have a long The rectangular cross-section of the surge tank forms a space with both ends open while extending along the arrangement direction of the intake pipes between the risers of the intake pipes connected to the bottom of the buffer tank and the buffer tank...
