    Abstract: To provide a vehicle provided with a valve-stop-mechanism-equipped internal combustion engine capable of ensuring a negative pressure in a brake booster while preventing with reliability fresh air from flowing into a catalyst during a valve stop control. An internal combustion engine (10) provided with a valve stop mechanism capable of changing the operational state of an intake valve (24) between a valve operating state and a valve closed/stopped state is provided. A brake booster (40) is provided capable of assisting operation of a brake pedal (38) of the vehicle. Exhaust side negative pressure passages (46, 54) are provided as communication passages that are configured to be in communication with each branch pipe section (22b1) of an exhaust manifold (22b) in a period in which a negative pressure is generated in the case where the intake valve (24) is in the valve closed/stopped state while an exhaust valve (28) is allowed to open and close. The remaining end of the second exhaust side negative pressure passage (54) is connected to the brake booster (40).

    Abstract: PROBLEM TO BE SOLVED: To improve safety against collision, by securing a crush stroke in collision of a vehicle. SOLUTION: In shock absorbing structure of a vehicle V mounting an engine 10 thereon, a water pump 15 is disposed on a side of an engine main body 14, and at least a part of a housing 21 of the water pump 15 is made of material which can be broken by a collision load in the collision of the vehicle. The impact load can break parts 22, 23 made of the material in the collision of the vehicle. Therefore, the crush stroke can be secured by the length of the parts 22, 23 so as to improve the safety against collision. COPYRIGHT: (C)2007,JPO&INPIT
