Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 大型の多シリンダエンジンであっても、コン パクトな構成で効率よく吸気の脈動を低減できるように する。 【解決手段】 アフタークーラー13a〜13c及びタ ーボチャージャ10a〜10cを備えた多シリンダエン ジンの吸気構造において、複数のシリンダ毎に1個の吸 気マニホールド6a〜6bを独立して複数取付けると共 に、各吸気マニホールド6a〜6b内にアフタークーラ ー13a〜13cを設け、アフタークーラー13a〜1 3cにて仕切られる各吸気通路の上流側室15a同士を 連通した構成にした。 (57) [Problem] To enable even a large multi-cylinder engine to efficiently reduce intake pulsation with a compact configuration. SOLUTION: In an intake structure of a multi-cylinder engine provided with aftercoolers 13a to 13c and turbochargers 10a to 10c, a plurality of intake manifolds 6a to 6b are independently attached to a plurality of cylinders, and each intake manifold is provided. After coolers 13a to 13c are provided in 6a to 6b, and the after coolers 13a to 13c are provided. The upstream side chambers 15a of each intake passage partitioned by 3c are connected to each other.
