Abstract

The invention provides a stable pipeline type exhaust manifold which comprises a connecting branch pipe, and bottom plates are arranged on the connecting branch pipe. The exhaust manifold further comprises a fixing mechanism arranged between the two bottom plates, and one end of the fixing mechanism abuts against the side walls, close to the connecting branch pipe, of the bottom plates. The other end of the fixing mechanism is in threaded connection with a flange on an engine, so that the connecting branch pipe is fixed to the engine. And a cooling piece movably arranged on the connecting branch pipe in a sleeving mode and can move in the axis direction of the connecting branch pipe, so that the cooling piece has a locking state in which the cooling piece abuts against the fixing mechanism and a moving state in which the cooling piece is far away from the fixing mechanism. Compared with the mode that a bolt directly penetrates through the bottom plates to be in threaded connection with the flange on the engine in the prior art, the phenomenon that the temperature of the bottom plates and the connecting branch pipe is too high due to the fact that the bolt directly transfers heat to the bottom plates can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of exhaust manifolds, in particular to a stable pipeline exhaust manifold. Background technique [0002] The exhaust manifold is connected to the cylinder block of the engine. It is to gather the exhaust of each cylinder and lead it into the exhaust manifold. The standard, the cost of the engine, the matching layout of the front cabin of the vehicle and the temperature field, etc., the commonly used exhaust manifolds are divided into two types: cast iron manifolds and stainless steel manifolds in terms of materials and processing techniques. [0003] Most of the automobile exhaust manifolds on the market will become hot at high temperature after long-term use, and their heat resistance is poor, and the automobile exhaust manifolds are easy to loosen due to vibration. Contents of the invention [0004] In view of this, the main purpose of the present invention is to solve the problem that the automobile ex...
