摘要： PURPOSE:To have precision control of the amount of exhaust feedback in response to the actual operating condition of an internal combustion engine by setting the amount of exhaust feedback in accordance with the load of engine and the pressure difference between suction and exhaust gases, and making correction of the amount of exhaust feedback with the pressure difference and the number of revolutions. CONSTITUTION:Signals from a pressure difference sensor 52, throttle sensor 48, lift position sensor 36, and coolant temp. sensor 50 are fed in an electronic control device 46 through an A-D converter circuit 68. Signal from a revolving speed sensor 49 is fed in the same electric control device 46 via a pulse generator circuit 69. In the ROM 62 of said electronic control device 46, the converted EGR ratio as the lift amount of an EGR control valve is stored upon preparing in the form of a two-dimensional map of the load of engine and the pressure difference between suction and exhaust gases. A map for correction of pressure difference is prepared and stored in this ROM 62. Thus the EGR ratio is set with the suction/exhaust pressure difference as parameter, and the EGR ratio is corrected with pressure difference and the number of revolutions.

This enables precision control of the amount of exhaust feedback in response to the actual operating conditions of internal combustion engine.

摘要： PURPOSE:To prevent the generation of dislocation to a folded part so as to seal a pressure fluid positively even with the generation of a crack to a bent part by folding the peripheral edge part of a hole bored in a metal base radially so as to be overlapped with the body part of the base, and welding the folded part to the body part along the peripheral edge of the hole. CONSTITUTION:A metal gasket is provided with a base 10 made of an elastic metal plate, and the peripheral edge part of a hole bored to form a combustion chamber hole 14 is folded onto the protruding part 20a side of a bead 20 to form a folded part 10b. The folded part 10b is welded, along the hole peripheral edge, to the body part 10d of the base 10 by a laser welding machine so as to form a substantially continuous weld line 21 and the folded part 10b is adhesively jointed to the body part 10d. Accordingly, even if a crack is generated to a bent part 10c, there is no fear of dislocation being generated to the folded part 10b or an interstice being generated to a joint face between the body part 10 and the folded part 10b to cause the admission of high-temperature high-pressure combustion gas, so that stable sealing performance is secured.

摘要： PURPOSE:To prevent the breakage of a grommet by a plurality of projections in projection, separating each other, on the periphery of a through hole on a gasket body of an engine for automobile. CONSTITUTION:Thin metal subplates 4 are piled on the upper surface of a gasket body 1, i.e., on the cylinder head side, and a grommet 5 is formed by downward turning back the edge part on the combustion chamber hole 2 side of the subplate 4, and further, a metal ring-shaped member 6 is accommodated inside. A plurality of projections 7 are formed in projection downward on the periphery of the combustion chamber hole 2 of the gasket body 1, separating each other, and springily attached with a cylinder block. The projection 7 is formed into a linear or arcuate form at each intermediate position of four bolt holes 3 on the periphery of the combustion chamber hole 2. Therefore, the relatively large variation of the gap between the cylinder head and the cylinder block is suppressed, and the breakage of the grommet is effectively prevented, and the sealing action can be maintained for a longer period.

摘要： PURPOSE:To maintain favorable sealing effect for a long time by setting the height and width of an inner bead lower and narrower than the height and width of an outer bead, and further setting the height of the inner bead low at the position close to bolt fastening position and high at the position apart from it. CONSTITUTION:The height h1 and h2 of an inner bead 4 is set so that it may be lowest h2 at the position close to a bolt fastening position, that is, a bolt hole 3, and that it may be higher h1 smoothly as it separates from there, whereby even if the face pressure between a cylinder head and a cylinder block falls as it separates from the bolt fastening position, approximately equal contact force can be obtained. And at the same time with this, the width w1 and w2 of the inner bead 4 are so arranged that it may be narrowest w2 at the position close to the bolt fastening position and that it may be wider w1 smoothly as it separates from there. Since the inner bead 4 is lower than the outer bead 5 and besides narrower, the rigidity of the inner bead 4 can be made larger than that of the outer bead 5.

摘要： PURPOSE:To prevent decrease in the inside diameter by forming a bearing layer containing resin on a back plate, forming an axial through groove on the bearing layer, and exposing the back plate of a designated width to the bottom portion of the groove to let thermal expansion escape in the circumferential direction. CONSTITUTION:A circular bush is formed by forming a bearing layer 2 on a back plate 1, providing chamfering portions 4 on the inner periphery sides of both end portions 3, and bending the above cylindrically in such a manner that the bearing layer is put inside to meet both end portions 3 mutually. The chamfering portions 4 are made larger in such a manner as to form a through groove where the back plate 1 is exposed when both end portions 3 are joined. Further, axial through grooves 6, 7 are provided to expose the back plate 1. Resin such as PTFE, polyacetal, or the like is contained in the bearing layer. The thermal expansion of the bearing layer is let escape in the circumferential direction by the through grooves, and the inside diameter is decreased not to change the clearance with the shaft. Furthermore, the decrease in the area of a sliding surface can be prevented as much as possible.

摘要： PURPOSE:To enhance sealing performance by forming a cavity in a sealing part in the direction of compression, and allowing the sealing part to perform a relatively free compression so that the volume of the cavity can be contracted at the time of compression. CONSTITUTION:A through hole 8 is formed in a gasket body 4, and the inner circumferential periphery part of the through hole in a gasket member 1 positioned on the lower side is bent upward to form a S-shape in its section on the inner circumferential side of a sealing part 9. In the sealing part 9, a cavity 10 is formed in the direction of compression to allow a relatively free compression, and the sealing part 9 is brought into close contact by a uniform contacting force between a cylinder head 5 and a cylinder block 6. Thus, a secure sealing action can be obtained.

摘要： PURPOSE:To make the axial dimension of a case highly accurate and prevent rotation, falling and durability deterioration of lip type seals by providing a space regulating member for maintaining an internal between a caulked part and a supporting part to the specified interval at the time of caulking the caulked part. CONSTITUTION:The caulked part 5d of a case 5 is bent radially inward from a specified position in the axial direction so as to press-hold the peripheral part of each enclosed member strongly and compress lip type seals 7, 8, 9, but because of holding in the state of a first space regulating member 14, a spacer 10 and a second space regulating member 15 respectively with high rigidity being connected axially between the caulked part 5d and a supporting part 5c, the respective lip type seals 7, 8, 9 are compressed independently by desirable quantity. In addition, as the axial dimension L between the caulked part 5d and supporting part 5c after assembling is obtained by the highly rigid space regulating members 14, 15 and spacer 10, the axial dimension of the whole case 5 can be controlled with high accuracy.
