  "textContent": "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).",
