Abstract
The utility model discloses an automobile engine exhaust connector which comprises a connector inner circular cavity (3) and a connector body (4). The connector body is provided with a bolt hole (5) connected with a silencer and an exhaust manifold. The automobile engine exhaust connector is characterized in that the outside shape of the connector body is rectangular. Through the change of the outside shape of the connector body, so that overall strength of the connector is strengthened, each part of the connector is even in strength, the service life of the exhaust connector can be effectively improved, casting process is simple, exhaust connector cost is low, the overall strength of the connector is strong, the service life of the exhaust connector is long, and operational reliability of the automobile engine exhaust connector is improved.
Description
Technical field
The utility model relates to a kind of motor car engine connector element, especially a kind of automobile engine to exhaust joint.
Background technique
Motor car engine is in running, and the high-temp waste gas in the engine cylinder-body is discharged by outlet pipe, because the automobile engine to exhaust joint directly links to each other with outlet pipe, the temperature of exhaust wall is directly transferred on the joint.Measure through appropriate authority, the exhaust pipe wall temperature of the supercharged engine in modern age can reach more than 450 degree, the exhaust joint that ordinary metallic material is made can only tolerate the following high temperature of 400 degree, surpass 400 degree and be prone to the situations such as crackle, existing automobile engine to exhaust joint geometry design is reasonable not in addition, the concrete shape structure as shown in Figure 1, it comprises round cavity 1 and fittings body 2, the fittings body outside is concavo-convex waveform, bulk strength is low and inhomogeneous, especially spill position intensity is minimum, the situation generations such as crack deformation very easily occur, affect its working life, and the silencing apparatus and the exhaust manifold that are attached thereto are broken down, its concave-convex shape moulding makes casting technique cumbersome in addition, and cost of production increases.Therefore develop that a kind of casting technique is simple, cost of production is low, bulk strength is high, the automobile engine to exhaust joint of long service life is very necessary.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide that a kind of bulk strength is high, long service life, the simple automobile engine to exhaust joint of casting technique.The purpose of this utility model realizes by following technical proposals: the utility model comprises joint internal round chamber and fittings body, and fittings body is provided with the bolt hole that links to each other with exhaust manifold with the device that disappears, and it is characterized in that the fittings body profile is rectangle.
The utility model increases the joint bulk strength by the outer shape that changes exhaust joint, and joint even intensity everywhere, but Effective Raise exhaust joint working life.From above-mentioned situation as can be known, the purpose of this utility model can realize.Compared with prior art it has following advantage: casting technique is simple, cost of production is low, bulk strength is high, long service life, the automobile engine to exhaust joint operational safety that improved.
