To improve fuel consumption performance in actual use of a power unit including an engine body which burns an air-fuel mixture.SOLUTION: A motor vehicle 1 includes: a capsule device 30 which is disposed in a manner that at least an exhaust pipe 18 is located outside the capsule device 30 and at least an engine body 11 is enclosed thereby in the motor vehicle 1 having a power unit which is provided at a front chamber 3 of the motor vehicle 1, causes an air-fuel mixture to be burned in the engine body 11, and exhausts through the exhaust pipe 18; a communication port 41 which is formed on a side surface of the front chamber 3 of the motor vehicle 1 and allows the front chamber 3 and an interior of a wheel house 23 to communicate with each other; a communication port opening/closing member 42 which is movably provided so as to close the communication port 41; and a control part 44 which controls opening/closing of the communication port 41 by the communication port opening/closing member 42. The communication port 41 opens at the rear side of a front surface of the capsule device 30.SELECTED DRAWING: Figure 4
【課題】混合気を燃焼させるエンジン本体を含むパワーユニットの、実使用での燃費性能を向上させる。【解決手段】自動車1は、自動車1の前室3に設けられて混合気をエンジン本体11で燃焼させて排気管18を通じて排気するパワーユニットを有する自動車1についての、少なくとも排気管18を外とするとともに少なくともエンジン本体11を囲うカプセル装置30と、自動車1の前室3の側面に形成され、前室3とホイールハウス23の内部とを連通する連通口41と、連通口41を閉じるように可動可能に設けられる連通口開閉部材42と、口開閉部材による連通口41の開閉を制御する制御部44と、を有し、連通口41は、カプセル装置30の前面より後側において開口する。【選択図】図4
