Publication number: 20150083655Abstract: Provided is an oil deterioration prevention device with which the trapping effect with respect to oil deteriorated components can be improved and with which the oil passage resistance can be reduced, thereby suppressing a rise in pressure loss. This oil deterioration prevention device is equipped with a filter unit equipped with a filter material that filters oil; and a deterioration prevention unit equipped with a powdery deterioration suppressing agent that suppresses oil deterioration. The deterioration prevention unit contains a mesoporous inorganic material, and of the oil fed from an oil storage unit, the oil filtered by the filter unit is fed to parts which are to be lubricated, and the oil in which deterioration has been suppressed by the deterioration prevention unit is returned to the oil storage unit or is fed to the parts to be lubricated.Type: ApplicationFiled: April 30, 2013Publication date: March 26, 2015Applicants: TOYOTA BOSHOKU KABUSHIKI KAISHA, TOYOTA JIDOSHA KABUSHIKI KAISHA, KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHOInventors: Hideto Morishita, Yasuhiro Saito, Ippei Fukutomi, Motoichi Murakami, Katsuichi Miyasaka, Yasuhiro Ohmiya, Hiroshi Moritani, Mamoru Tohyama, Narihito Tatsuda

Patent number: 8646431Abstract: 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 provided with a valve stop mechanism capable of changing the operational state of an intake valve between a valve operating state and a valve closed/stopped state is provided. A brake booster is provided capable of assisting operation of a brake pedal of the vehicle. Exhaust side negative pressure passages are provided as communication passages that are configured to be in communication with each branch pipe section of an exhaust manifold in a period in which a negative pressure is generated in the case where the intake valve is in the valve closed/stopped state while an exhaust valve is allowed to open and close. The remaining end of the second exhaust side negative pressure passage is connected to the brake booster.Type: GrantFiled: March 2, 2010Date of Patent: February 11, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Katsuichi Miyasaka, Akio Kidooka
