Abstract

A compaction system for an inclined plane connecting an engine exhaust manifold with a cylinder cover is used for hermetically connecting the exhaust manifold with the cylinder cover. The compaction system comprises the exhaust manifold and an exhaust manifold press cake, a mounting surface of a mounting flange of the exhaust manifold is a plane clinging to the cylinder cover, at least five exhaust manifold stud mounting and positioning holes are arranged on the upper portion of the back of the mounting flange of the exhaust manifold, the lower portion of the back of the mounting flange of the exhaust manifold is an inclined plane structure, an included angle between the inclined plane and the mounting surface is beta, at least four positioning grooves are arranged on the inclined plane, and an exhaust system is assembled with the exhaust manifold press cake via the positioning grooves, and then is fixed on the cylinder cover via exhaust manifold mounting studs. The engine exhaust manifold is assembled and disassembled more conveniently, the exhaust system is arranged more compactly, particularly, the problem that exhaust manifold mounting studs of a heavy supercharging exhaust system are easy to loose and drop is solved, and the problem that an exhaust manifold of the heavy supercharging exhaust system deforms and leaks air is also solved.

Description

technical field [0001] The invention relates to a sealing connection system, which is especially suitable for the sealing connection between an exhaust manifold of an automobile engine and a cylinder head, and belongs to the technical field of engines. Background technique [0002] With the improvement of global automobile production and technical level, engine direct injection and exhaust gas turbocharging technologies have been widely used, so the requirements for the overall quality of the engine exhaust system are getting higher and higher. In order to avoid the deformation of the exhaust manifold caused by the increase of exhaust temperature, the structure and material of the engine exhaust manifold have been continuously improved. At the same time, the problem of loose connection caused by the increase of the mass of the exhaust system has appeared. risk of exhaust system leaks. Therefore, designing an exhaust system that is easy to disassemble, can prevent loose asse...
