Abstract
The utility model provides an engine exhaust system with a rear supercharger. The rear engine exhaust system comprises an engine cylinder block, an exhaust connection pipe, an exhaust manifold and the supercharger; one end of the exhaust connection pipe is fixed to an exhaust connection pipe support fixed to the rear end of the engine block, and the other end of the exhaust connection pipe is connected with the exhaust manifold through a flange; the supercharger is located on the exhaust connection pipe, and an exhaust tail pipe is located at the vortex end of the supercharger and is connected with an engine cylinder cover through an auxiliary support; the outer side of the exhaust connection pipe is provided with an EGR pipe; the flange surface, connected with the exhaust manifold, of the exhaust connection pipe is axially connected with the exhaust manifold in the vertical direction; the engine cylinder block is transversely distributed. The engine exhaust system solves the problems that in an original engine exhaust system with the rear supercharger, components craze, a gasket leaks air, a bolt loosens, and a support cracks, so that the engine exhaust system works more stably, and the safety factor is greatly increased.
Description
Technical field
The utility model relates to a kind of automobile engine exhaust system, particularly relates to a kind of pressurized machine rear engine vent systems.
Background technique
For the vent systems of motor car engine, in order more effectively to utilize exhaust energy, consider the compactedness of structural configuration simultaneously, generally exhaust-gas turbocharger is arranged on enmgine exhaust.But for preposition forerunner's motor, due to the narrow limitation of arrangement, need to motor is horizontal, pressurized machine is arranged in motor rear end.Pressurized machine postposition increases engine exhaust system component, stiffness degradation, and vibrations increase, and vent systems assembling is complicated, and erection stress increases, and vent systems reliability is exerted an influence.Conventionally motor there will be the failure phenomenons such as exhaust system component cracking, pad gas leakage, bolt get loose, support fracture.
Model utility content
The utility model pressurized machine rear engine vent systems by improvement design, adjustment assembly order, the technological means such as stand test layout of optimizing have solved the part cracks, the pad gas leakage that exist in pressurized machine rear engine vent systems in the past, bolt gets loose and the Problem of Failure such as support fracture, make engine exhaust system more stable work, safety coefficient improves greatly.
Technical solution adopted in the utility model is:
A pressurized machine rear engine vent systems, comprises engine cylinder-body, vent connection, gas exhaust manifold and pressurized machine; One end of described vent connection is fixed on vent connection support, and vent connection support is fixed on engine cylinder-body rear end, and the vent connection the other end is connected with gas exhaust manifold by flange; Described pressurized machine is positioned on vent connection, and described tailpipe is positioned at pressurized machine whirlpool end, by auxiliary stand, is connected with engine cylinder cover; Described vent connection arranged outside has EGR pipe; Described vent connection with gas exhaust manifold connecting flange faces for to be connected with the axial Vertical direction of gas exhaust manifold; Described engine cylinder-body lateral arrangement.
Between described gas exhaust manifold and vent connection, be provided with pad, described gasket surface is molybdenum disulfide coating, and coating thickness is 0.005-0.015mm.
The beneficial effect of the relative prior art of the utility model:
The utility model pressurized machine rear engine vent systems by improvement design, adjustment assembly order, the technological means such as stand test layout of optimizing have solved the part cracks, the pad gas leakage that exist in pressurized machine rear engine vent systems in the past, bolt gets loose and the Problem of Failure such as support fracture, have improved the workmanship of engine exhaust system.This rear engine vent systems design proposal can be widely used in transverse engine, for the exploitation of engine component, also has certain reference and directive significance.
