description PROBLEM TO BE SOLVED: To provide an engine intake system capable of suppressing the aggregation of engine oil in the vicinity of a passage inlet 1b of a throttle intake passage 1.SOLUTION: In an engine intake system, as viewed in parallel with a center axis 1a of the throttle intake passage 1, the passage outlet 5a of a blow-by gas passage 5 is directed, at a position overlapping the passage inlet 1b of the throttle intake passage 1, toward the passage inlet 1b of the throttle intake passage 1 so that one end part of the erection portion of a throttle valve stem 3a installed in the throttle intake passage 1 is used as one end shaft part 3b. As viewed in a direction parallel to the center axis 1a of the throttle intake passage 1, a passage outlet peripheral wall 5b of the blow-by gas passage 5 is extracted from a portion 1d, close to an axial one end part 3b, of a passage inlet circumferential edge part 1c of the throttle intake passage 1 toward the passage inlet 1b of the throttle intake passage 1, and this passage outlet peripheral wall 5b overlaps the one end shaft part 3b. 【課題】スロットル吸気通路1の通路入口1b付近でのエンジンオイルの凝集を抑制することができるエンジンの吸気装置を提供する。【解決手段】エンジンの吸気装置において、スロットル吸気通路1の中心軸線1aと平行な向きに見て、ブローバイガス通路5の通路出口5aが、スロットル吸気通路1の通路入口1bとオーバーラップする位置で、スロットル吸気通路1の通路入口1bに向けられ、スロットル吸気通路1内に架設されたスロットル弁軸3aの架設部分の一端部を軸一端部3bとして、スロットル吸気通路1の中心軸線1aと平行な向きに見て、スロットル吸気通路1の通路入口周縁部1cのうちの軸一端部3b寄りの部分1dから、ブローバイガス通路5の通路出口周壁5bが、スロットル吸気通路1の通路入口1bに向けて導出され、この通路出口周壁5bが、軸一端部3bとオーバーラップしている。【選択図】 図1
