Abstract
The utility model relates to an engine exhaust pipe which comprises a first branch pipe and an exhaust pipe, wherein one end of the first branch pipe is connected with a gas inlet flange, the other end of the first branch pipe is connected with a second branch pipe which is connected with a third branch pipe through a corrugated pipe, the third branch pipe is connected to one end of the exhaust pipe through a center port, and the other end of the exhaust pipe is connected with a fourth branch pipe through an eccentric port. The engine exhaust pipe is simple in structure, beautiful in appearance and convenient to install, and can be conveniently connected with an exhaust manifold through the gas inlet flange, can reduce the exhaust back pressure, and increases catalytic effects, improves the whole performance of an engine, and is suitable for large-scale popularization and application.
Description
Technical field
The utility model relates to a kind of engine exhaust pipe that is connected with enmgine exhaust.
Background technique
Motor is communicated with cylinder with outlet pipe; The waste gas that cylinder is discharged is a kind of gas of HTHP; This high temperature and high pressure gas is discharged from cylinder, is input in the turbosupercharger through outlet pipe, promotes turbocharger operation through this high temperature and high pressure gas.But the existing exhaust pipe structure complicacy that is connected with enmgine exhaust, the installation steps complicacy, unstable properties has a strong impact on the overall performance of motor, makes that also the air flue exhaust back pressure is bigger, causes engine power, moment of torsion to descend to some extent.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of engine exhaust pipe simple in structure, easy to use.
The engine exhaust pipe of the utility model; Comprise first arm and outlet pipe; One end of said first arm connects inlet flange, and the other end of first arm connects second arm, and second arm connects the 3rd arm through bellows; The 3rd arm is connected an end place of outlet pipe through hub-interface, and the other end of outlet pipe connects the 4th arm through eccentric interface.
The engine exhaust pipe of the utility model, the outer surface of said the 3rd arm are provided with interconnective first suspension member and second suspension member.
The engine exhaust pipe of the utility model, through the compound adhesive fixed-bearing, the liner in the outlet pipe outside is provided with thermal shield on the outer wall of said outlet pipe.
The engine exhaust pipe of the utility model, the joint near the 4th arm and outlet pipe on the outer wall of said the 4th arm is provided with welded nut.
Compared with prior art the beneficial effect of the utility model is: the engine exhaust pipe of the utility model is simple in structure; Beautiful shape can be connected with gas exhaust manifold through inlet flange easily, and is easy for installation; Can reduce exhaust back pressure; Increase catalytic effect, improved the motor overall performance, suit to apply on a large scale.
