Abstract
The present invention provides an oil deterioration suppressing apparatus for an internal combustion engine comprising an oil reservoir section for reserving oil, a filtering component and an adsorption component provided in an oil passage, and a supply device for supplying the oil in the oil reservoir section to a side upstream of the adsorption component and the filtering component. The filtering component is configured to remove unnecessary products from the oil, and the adsorption component is configured to be positioned upstream of the filtering component to adsorb a predetermined acid component in the oil. Since the apparatus can remove a predetermined acid component in the oil from the oil in the adsorption component, it is possible to suppress generation of the sludge in the filtering component, thereby suppressing the oil deterioration appropriately.
