摘要： PROBLEM TO BE SOLVED: To increase the contact area between acidic substances which cause oil degradation and an alkaline substance which neutralizes the acidic substances, and to suppress manufacturing cost.
SOLUTION: Alkaline substance-containing porous films 2OA, 20B are installed on inner wall surface s6A, 7A of spaces 8, 9 which are within an internal combustion engine and in which at least one of oil, oil mist, and blowby gas exists. Since the films are 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.

摘要： PROBLEM TO BE SOLVED: To prevent drop-off of a low friction material, when the low friction material is disposed to a sliding face of a base material for giving self-lubricating property to the sliding face.
SOLUTION: Recess parts 21 are formed in the low friction material layer 20 so that a part of the base material 10 is exposed, and restraining layers 30 are formed on the surfaces of the recess parts. The recess part 21 is a tapered state so that its cross-section gets smaller toward the inside from the sliding face 2. Since the restraining layers 30 are formed to be brought into contact with the surfaces of the recess parts 21, the structure for geometrically restraining the low friction material layer 20 can be formed easily.

摘要： PROBLEM TO BE SOLVED: To provide a cylinder lubricating device capable of providing good lubricating performance in a cylinder of an engine, especially a diesel engine using fuel as lubricating oil.
SOLUTION: The cylinder lubrication device 20 is provided with a high pressure fuel injection valve 19 injecting fuel into the cylinder 21 of the engine 1 at high pressure, and a low pressure fuel injection valve 24 injecting fuel into the cylinder at low pressure. The low pressure fuel injection valve 24 is supplied with fuel by a lubrication pump supplying fuel as lubricating oil to an engine lubrication system such as a periphery of a cylinder head and a periphery of a crankshaft. Injected fuel can be adhered on a cylinder liner 22 without evaporating the same by injecting fuel into the cylinder 21 at low pressure. Consequently, fuel evaporates on the cylinder liner 22 to avoid getting into a dry condition to reduce friction.
