Abstract
Official abstract text for this publication.
A protector protects a high-pressure fuel pump for an internal combustion engine. A metal collar is insert-molded into a plate-shaped fiber reinforced plastic portion made of a fiber reinforced plastic of the protector. An outer circumferential surface of the collar includes an uneven portion and a smooth surface. The uneven portion includes recesses and projections arranged alternately in a thickness direction of the fiber reinforced plastic portion. The smooth portion includes a smooth surface parallel to the thickness direction of the fiber reinforced plastic portion. The uneven portion and the smooth portion are arranged in the thickness direction on the outer circumferential surface of the collar.
First claim
Opening claim text (preview).
What is claimed is: 1. A protector comprising: a plate-shaped fiber reinforced plastic portion made of a fiber reinforced plastic, the fiber reinforced plastic portion defining a thickness direction; and a metal collar insert-molded into the fiber reinforced plastic portion, wherein the protector and a high-pressure fuel pump are fastened to an engine body of an internal combustion engine by a bolt inserted through the collar, the protector protects the high-pressure fuel pump, an outer circumferential surface of the collar includes an uneven portion including recesses and projections arranged alternately in the thickness direction of the fiber reinforced plastic portion, and a smooth portion including a smooth surface parallel to the thickness direction, the uneven portion and the smooth portion are arranged in the thickness direction on the outer circumferential surface of the collar, and the collar is held between a flange of the high-pressure fuel pump and the engine body. 2. The protector according to claim 1 , wherein the fiber reinforced plastic portion has reinforcing fibers that are laminated in the thickness direction. 3. The protector according to claim 1 , wherein the smooth portion is one of two smooth portions, and the uneven portion is located between the two smooth portions in the thickness direction on the outer circumferential surface of the collar. 4. The protector according to claim 3 , wherein the protector includes a front surface and a rear surface, the collar includes a collar front surface exposed on the front surface of the protector and a collar rear surface exposed on the rear surface of the protector, the outer circumferential surface of the collar includes a front surface adjacent portion adjacent to the collar front surface and a rear surface adjacent portion adjacent to the collar rear surface, and the front surface adjacent portion and the rear surface adjacent portion are the smooth portions. 5. The protector according to claim 3 , wherein the uneven portion is located at a middle part of the outer circumferential surface of the collar in the thickness direction, and each of the two smooth portions, between which the uneven portion is located, accounts for twenty percent or more of a dimension of the collar in the thickness direction. 6. The protector according to claim 1 , wherein the fiber reinforced plastic is a carbon fiber reinforced plastic.
