摘要:
The present invention provides an oil deterioration prevention device that can prevent increase in pressure loss by reducing oilflow resistance. An oil deterioration prevention device 1 according to the present invention includes a filtering unit 3 with a filter element 10 that filters oil; and a deterioration prevention unit 4 having a powdery deterioration prevention agent 17 that prevents deterioration of oil, wherein out of oil fed from an oil containing unit 9, oil filtered by the filtering unit is fed to a part to be lubricated, and oil that is prevented from being deteriorated by the deterioration prevention unit is returned to the oil containing unit or sent to the part to be lubricated.
摘要:
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 (1) is equipped with: a filter unit (3) equipped with a filter material (10) that filters oil; and a deterioration prevention unit (4) equipped with a powdery deterioration suppressing agent (17) that suppresses oil deterioration. The deterioration prevention unit contains a mesoporous inorganic material, and of the oil fed from an oil storage unit (9), 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.

摘要:
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).
