A volume chamber for pressure wave reversal, which is formed to be smaller in size and is located downstream of the section of maximum cross-sectional area reduction rate change in the passage section, communicates with and blocks off the volume chamber and the passage section. An intake system for an engine, characterized in that it is provided with valve means for. (2) An intake system for an engine having a volume part in the intake system and a plurality of passage parts leading from the volume part to the combustion chamber of each cylinder, wherein the cross-sectional area of each passage part becomes smaller as the position goes downstream. A communication passage for pressure wave reversal is formed downstream of the maximum cross-sectional area reduction rate change part in these passage parts, and a valve that communicates and shuts off the communication passage and each passage part. An intake device for an engine, characterized in that it is provided with means.
