Title:
OIL DEGRADATION SUPPRESSION DEVICE FOR INTERNAL COMBUSTION ENGINE, FILM FOR SUPPRESSING OIL DEGRADATION, AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2010/097663
Kind Code:
A8
Abstract:
An alkaline substance-containing porous film (2OA, 20B) is installed on an inner wall surface (6A, 7A) of a space (8, 9) which is within an internal combustion engine and in which at least one of oil, oil mist, and blowby gas exists. Since the film is porous, the alkaline substance and acidic substances can be caused to contact each other, and can be reacted. Thus, the contact area can be increased, so that the neutralization reaction can be enhanced. Besides, since the film is installed as a separate component part, the masking as required in the material-applying or spreading process is not necessary, and thus manufacturing cost can be reduced.
