Abstract: PURPOSE: A camshaft for an engine is provided to improve endurance of the camshaft by locating a welding unit of a hollow shaft on an oil groove-processing unit. CONSTITUTION: A cam shaft of an engine comprises a front end piece(5) installing a cam pulley(3) on a cam shaft(1); a cam(7) formed on an outer portion of a hollow shaft(9); a bolt hole(11) arranged on a front end of the front end piece to mount the cam pulley; am oil seal face(13) mounted on an outer circumference of the bolt hole with a trust face(15); a bearing(19) placed on a neck face(17); and valve lift opening or closing a suction/drain valves by being attached to the cam. A welding unit welded by inserting the front-end piece into the hollow shaft. Thereby, the camshaft of the engine improves endurance of the camshaft by locating the welding unit of the hollow shaft on an oil groove-processing unit.

Abstract: PURPOSE: A machining structure for rigidity of a bowl edge portion of a direct injection type combustion chamber is provided to improve the rigidity of a bowl edge portion of a combustion chamber and increase the durability. CONSTITUTION: A combustion chamber(2) is formed with a bowl machining after cutting the upper surface of a piston(1). A machining structure for rigidity of a bowl edge portion of a direct injection type combustion chamber is formed on the upper surface of a lip portion(22) of the combustion chamber. A crown machining surface(3) has a larger inner diameter than the diameter of the lip portion. A crown machining surface(3) is downward formed toward the lip portion(22). An edge portion, which is a starting point of the lip portion is increased in the diameter. Thus, the rigidity of an edge portion of a combustion chamber is improved.

Abstract: PURPOSE: A check valve for oil jet and a manufacturing method thereof are provided to prevent abrasion by increasing the area of a ball mounting surface and to achieve fine organization and high hardness of the ball mounting surface. CONSTITUTION: A check valve for oil jet comprises a housing(210), a ball(220), a spring(240), and a cap(230). The housing comprises an inlet port(211) through which oil flows in from a main gallery and an outlet port(212) through which oil flows out to a nozzle. A rounded ball mounting surface(213) is formed on the inlet port. The ball opens and closes the inlet port by hydraulic pressure actuating on the inlet side of the housing. The spring supports the ball against the inlet port and repeats compression and restoration by the hydraulic pressure actuating on the inlet port. The cap pressed in an end of the housing supports the spring and restricts the downward movement of the ball.
