Claims (1)
該内燃機関の燃焼室へ通じる吸気通路をそなえ、
該エアクリーナの配設部より下流側の吸気通路部
分から分岐するように可変容積型のレゾネータが
設けられることにより、該吸気通路部分および該
レゾネータで吸気共鳴系が構成されて、該内燃機
関の運転状態に応じ該吸気共鳴系内の温度を制御
する吸気共鳴系温度制御手段が設けられたことを
特徴とする、内燃機関の吸気系構造。 In an intake system of an internal combustion engine, an intake passage leading from an air cleaner to a combustion chamber of the internal combustion engine is provided,
By providing a variable volume resonator so as to branch from the intake passage portion downstream of the air cleaner installation portion, the intake passage portion and the resonator constitute an intake resonance system, which improves the operation of the internal combustion engine. An intake system structure for an internal combustion engine, characterized in that an intake resonance system temperature control means is provided for controlling the temperature within the intake resonance system depending on the state.
