Abstract
The utility model relates to a single-layer metal cylinder gasket for a 1.3L gasoline engine. The cylinder gasket is a single-layer metal gasket with the thickness of 0.25mm; cylinder holes are uniformly distributed in the middle of the cylinder gasket; installing holes are uniformly distributed on the periphery of the cylinder gasket; water holes and oil holes are formed on the periphery of the cylinder gasket; rubber coating layers are arranged on the two peripheral surfaces of the oil holes, gas holes and the water holes of the cylinder gasket; an annular sealing rib of which the cross section is wave-shaped, and an annular sealing rib of which the cross section is basin-shaped are arranged on the periphery of the cylinder holes of the cylinder gasket; and annular sealing ribs of which the cross sections have an arch bridge shape are arranged on the periphery of the cylinder gasket on the outer sides of the water holes and the oil holes of the cylinder gasket. The single-layer metal cylinder gasket for the 1.3L gasoline engine is reasonable in structure improvement, can meet requirements of an engine with burst pressure of a cylinder of 14MPa, and can meet the state 4 emission requirement of the 1.3L gasoline engine.
Description
Technical field
The utility model belongs to technical field of internal combustion engines, relates in particular to a kind of 1.3 liters of petrolic head gaskets.
Background technique
The effect of head gasket is the reliable sealing that in internal-combustion engine normal operation process, guarantees oil, gas, water between cylinder cap and the cylinder body.Appropriate design can reduce cylinder deformation by a relatively large margin.Along with the continuous development of engine technology, the requirement of its head gasket sealing also progressively improves.Compound cylinder liner the earliest is accompanied by the continuous lifting of engine flare pressure and suffers exit, and the substitute is the stacked conducting plate cylinder liner.Advantages such as that the stacked conducting plate cylinder liner has is pollution-free, good reliability, durability are strong, can use repeatedly; But nowadays demand side reduces cost, alleviates problems such as complete machine quality, raising emission standard to motor, and the inferior position of stacked conducting plate cylinder liner progressively comes out.The single-layer metal head gasket is compared with the multiple layer metal head gasket, has all advantages of multiple layer metal cylinder pad, and performance is more outstanding at aspects such as constructional simplicity, process complexity, weight, sealing, costs.
Sealing configuration is unreasonable or too complicated around existing individual layer head gasket water hole, pore, the oilhole, and the quality control difficulty exists sealing validity and the relatively poor problem of reliability; The utility model through in the water hole, pore, oilhole design special construction and cooperate appropriate coating thickness to realize the sealing of water, gas, oil; This special construction only needs the muscle of punching press given shape on single-layer metal, and is simple in structure, produces to be prone to row; Quality control is simple, thereby improves sealing validity and reliability.
Summary of the invention
In order further to improve the sealability of single-layer metal head gasket, through the improvement to existing single-layer metal head gasket structure, the utility model provides a kind of can mate the petrolic single-layer metal head gasket of 1.3L.
Be used for the petrolic single-layer metal head gasket of 1.3L; Single-layer metal pad for thickness 0.25 ㎜; Said head gasket middle part is laid with cylinder-bore, and periphery is laid with mounting hole, and periphery also is provided with oilhole, water hole; Head gasket oil, gas, the two-sided rubber coating that is provided with of water hole periphery, the cylinder-bore periphery of said head gasket are provided with that a sliver transvers section is undulatory ring packing muscle and a sliver transvers section is the ring packing muscle of basin shape; The water hole of said head gasket, oilhole cylinder outside pad periphery are provided with the ring packing muscle that cross section is the arch bridge shape.
The ripple quantity of said cylinder-bore periphery ripple sealed muscle is 4, and the height of said ripple sealed muscle is 0.29～0.37 ㎜, and ripple sealed muscle cross-sectional width is 2 ㎜; The height of said shallow basin sealed muscle is 0.38～0.48 ㎜, a side margin of shallow basin sealed muscle apart from the cylinder-bore edge apart from 2.65mm.
The ring packing muscle height that said water hole, oilhole outer periphery cross section are the arch bridge shape is 0.38～0.48 ㎜.
The utility model architecture advances is reasonable, and can satisfy cylinder-firing pressure is the motor needs of 14MPa, can satisfy the requirement of 1.3L petrol engine state 4 dischargings.
