To provide an intake device of an internal combustion engine, which enables lowering of intake temperature thereby enabling improvement of the charging efficiency of the internal combustion engine, and consequently enables improvement of the output performance and the fuel economy of the internal combustion engine, even if an opening area for taking air into an engine room is reduced.SOLUTION: An intake device 10 comprises a volume portion 17 communicating with an intake duct 11 by a communication path 16a, the volume portion 17 comprises a resonator 13 installed near an air cleaner 12. The volume portion 17 has a front wall portion 17A extending in a cylinder row direction of an engine 2, and in the front wall portion 17A, a right end portion 17a separated from the air cleaner 12 is protruded frontward rather than a left end portion 17b near the air cleaner 12.SELECTED DRAWING: Figure 1

    【課題】エンジンルームに空気を取り入れるための開口面積が低減された場合であっても、吸気温度を下げて内燃機関の充填効率を向上でき、内燃機関の出力性能と燃費を向上できる内燃機関の吸気装置を提供すること。【解決手段】吸気装置10は、連通路16aによって吸気ダクト11に連通する容積部17を有し、容積部17がエアクリーナ12の近傍に設置されるレゾネータ13を備えている。容積部17は、エンジン2の気筒列方向に延びる前壁部17Aを有し、前壁部17Aは、エアクリーナ12から離れる右端部17aが、エアクリーナ12に近づく左端部17bよりも前方に突出している。【選択図】図1
