PROBLEM TO BE SOLVED: To prevent a purge control valve 45 from damaging fuel-based components 39, 53 in vehicle collision, with purge responsiveness of evaporated fuel enhanced by the purge control valve 45.SOLUTION: An engine includes: fuel-based components 39, 53 provided on a cylinder head 7; a purge control valve 45 provided in a suction passage on a downstream side with respect to a throttle valve 17, and configured to control an amount of evaporated fuel to be purged; and suction pipes 51, 52 constituting the suction passage on a downstream side of the throttle valve, and extending in a cylinder-row direction. In a vehicle front view or vehicle side view, the purge control valve 45 is disposed in front of the suction pipes 51, 52, and the fuel-based components 39, 53 are disposed on an opposite side to the purge control valve 45 with the suction pipes 51, 52 held therebetween.SELECTED DRAWING: Figure 2 【課題】パージ制御弁４５による蒸発燃料のパージ応答性を高めながら、車両衝突時にパージ制御弁４５が燃料系部品３９，５３を損傷することを防止する。【解決手段】シリンダヘッド７の上に設けられた燃料系部品３９，５３とスロットルバルブ１７よりも下流側の吸気通路にパージする蒸発燃料の量を制御するパージ制御弁４５と、スロットルバルブ下流側の吸気通路を構成する気筒列方向に延びる吸気管５１，５２とを備え、車両前面視又は車両側面視において、吸気管５１，５２の手前側にパージ制御弁４５を配設し、該吸気管５１，５２を挟んでパージ制御弁４５の反対側に燃料系部品３９，５３を配設する。【選択図】図２
