Exhaust manifold gasket and its applied exhaust manifold and engine

Abstract

The invention discloses an exhaust manifold gasket. The exhaust manifold gasket is connected between a gas inlet joint of an exhaust manifold and a cylinder of an engine, and comprises a base sheet located between the gas inlet joint and the cylinder and a wrapping sheet arranged on the edge of the base sheet. The wrapping sheet is arranged between the exhaust manifold and a water collecting pipe of the engine. The invention further discloses the exhaust manifold with the exhaust manifold gasket and the engine. The exhaust manifold gasket comprises the base sheet and the wrapping sheet, the purpose of relieving the force between the gas inlet joint and the cylinder and guaranteeing waste gas to be sealed can be achieved by the aid of the base sheet, the wrapping sheet is used for forming a partitioning mechanism to allow the heat transmitted to the cooling water in the water collecting pipe from the exhaust manifold to be reduced, and accordingly unexpected effect on engine cooling effect by the exhaust manifold is relieved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an exhaust manifold gasket. The present invention also relates to an exhaust manifold having the above exhaust manifold gasket and an engine having the exhaust manifold gasket. Background technique [0002] The exhaust system of the engine is a relatively important part of the engine, which has a great influence on the working performance of the engine. The exhaust manifold is a commonly used component in the engine exhaust system. It is connected to the engine cylinder block and can guide the exhaust of each cylinder into the exhaust manifold, thereby reducing the exhaust resistance of the engine and avoiding the exhaust of each cylinder. interfere with each other. [0003] The exhaust manifold mainly includes an intake joint, an air outlet joint, and a manifold arranged between the intake joint and the air outlet joint. The intake joint is connected to the cylinder through th...

AI Technical Summary

Problems solved by technology

Exhaust manifold gaskets currently used are generally formed by integral stamping, which is basically a planar structure. Since the temperature of the exhaust manifold will gradually rise when the engine is working, and a water collecting pipe is usually arranged above the exhaust manifold, the exhaust The temperature of the manifold will be transferred to the cooling water in the water collecting pipe, causing the cooling effect of the engine to decrease
