Embodiment Construction

[0009] see figure 1 , the specific embodiment adopts the following technical scheme: it includes a gasket body 1, a corrugation 2, and a locking device 3; the corrugation 2 is arranged on the edge of the cylinder mouth of the gasket body 1, and the corrugation 2 is provided with a locking device 3 , the width of the corrugated 2 is 0.5-1.0mm, the height is 0.1-0.2mm, and the thickness of the locking device 3 is 0.05-0.1mm.

[0010] The gasket body 1 uses a high-strength, high-hardness, and high-elasticity stainless steel cold-rolled plate or an alloy carbon steel sheet as a base material.

[0011] The specific embodiment has the following beneficial effects: it reduces the stress amplitude in the vertical direction of the cylinder head gasket when the engine is running, prevents the fatigue damage of the elastic gasket, and improves the high temperature and high pressure air sealing performance of the cylinder head part of the cylinder head gasket.

Abstract

The invention discloses a novel multi-wave metal engine cylinder cover sealing gasket and relates to the technical field of engine fittings. The novel multi-wave metal engine cylinder cover sealing gasket comprises a gasket body (1), crinkles (2) and locking devices (3), wherein the crinkles (2) are arranged at the edge of a cylinder port of the gasket body (1), the locking devices (3) are arranged on the crinkles (2), each crinkle (2) is 0.5-1.0mm wide and 0.1-0.2mm high, and each locking device (3) is 0.05-0.1mm thick. The stress amplitude of the cylinder gasket in the vertical direction during operation of an engine is reduced, fatigue damage of the elastic gasket can be prevented, and therefore the sealing performance for high temperature and high pressure gas at the cylinder port of the engine gasket is improved.

Description

Technical field: [0001] The invention relates to the technical field of engine accessories, in particular to a novel multi-wave metal engine cylinder head sealing gasket. Background technique: [0002] The engine cylinder head gasket is a high-demand single-layer or multi-layer cylinder head gasket that is applied to the junction of the body and the cylinder head of an engine fueled by various fuels (diesel, gasoline, liquefied gas, natural gas, etc.). [0003] The existing engine cylinder head gasket is affected by the vibration amplitude when the engine is running, which is easy to cause fatigue damage, thereby affecting the sealing performance. Invention content: [0004] The purpose of this invention is to provide a new type of multi-wave metal engine cylinder head sealing gasket, which reduces the stress amplitude of the vertical direction of the cylinder gasket when the engine is running, and can prevent the fatigue damage of the elastic gasket, thereby improving the...
