Abstract

An exhaust device of an engine comprises exhaust pipes and superchargers and is characterized in that the exhaust pipes are divided into two groups, and either group of exhaust pipes include four gas cylinders and are provided with the superchargers; either group of exhaust pipes are a whole pipe consisting of one gas outlet (11) and four gas inlets; the four gas inlets are respectively connected with the respective corresponding exhaust ports of the four gas cylinders; the four gas inlets are communicated with the gas outlet (11); and the gas outlet (11) is arranged at the side part of the whole pipe. Compared with the prior art, the exhaust device of the engine has the advantages that the manufacture and assembly technologies of the exhaust device are simple, the overall volume is small, and the cost is low; additionally, by adopting the exhaust device of the engine, the problems of mutual exhausting interference among the gas cylinders are also solved, the gas inlet and outlet relations of a diesel engine are improved, the oil consumption is lower, the problem of black smoke is improved, and the performances of the complete machine of the diesel engine are also improved.

Description

The venting gas appliance of motor

Technical field

The utility model relates to a kind of venting gas appliance manufacture technology field of motor.

Background technique

Existing a kind of patent No. is that the Chinese model utility of CN200920253639.5 " a kind of Diesel Engine Exhaust Pipe " by name discloses a kind of structure; It is characterized in that exhaust manifold one end is communicated with two gas exhaust manifolds that connect the waste gas of combustion chamber outlet, the other end is communicated with a manifold that leads to EGR valve waste gas chamber; Above-mentioned outlet pipe is by two gas exhaust manifolds that are connected with exhaust manifold and a manifold global formation that leads to EGR valve waste gas chamber; The utility model can improve turbocharger efficiency, suction pressure and air inflow, effectively reduces pumping work, reduces the discharging of diesel engine, and makes structure compact more.But the shortcoming of this structure is, an exhaust manifold only connects two exhaust branch pipes, and exhaust is little; Cost is high, because of having only a pressurized machine in this structure, when operating at full capacity, quickens serious the hysteresis again; Consumption oil is many, black smoke is big, power is little, and reduces maneuverability, so its structure awaits to improve.

Summary of the invention

The utility model technical problem to be solved be provide to above-mentioned existing technology present situation a kind of simple in structure, cost is low, it is low and improve the venting gas appliance of a kind of motor of maneuverability to eliminate over-emitting black exhaust and oil consumption.

The utility model solves the problems of the technologies described above the technological scheme that is adopted: the venting gas appliance of this motor; Include outlet pipe and pressurized machine; It is characterized in that: said outlet pipe divides two groups, and per four cylinders are one group, and every group of outlet pipe is provided with pressurized machine.

As improvement; Said every group of outlet pipe is an air outlet and four integral tube that suction port is formed; Said four suction ports are connected with the relief opening of each self-corresponding four cylinder respectively, and four suction ports are connected with the air outlet, and said air outlet is positioned at the sidepiece of said integral tube.

Improve again; The concrete structure of said integral tube is: said integral tube is made up of first body and second body; One end of first body is provided with the inlet hole that is connected with the relief opening of first cylinder; The other end at first body is provided with the ventilating hole that is connected with second body, and said air outlet is positioned on the sidepiece of first body, and second body is provided with three suction ports that are connected with each self-corresponding relief opening of three cylinders respectively; End at second body is provided with vent, and said ventilating hole and vent are interconnected to overall structure through connection set with first body and second body.

Improve, said connection set is a flange again, and said first body and second body are interconnected to overall structure through flange.

Improve, three suction ports of said second body extension tube through separately respectively are connected with vent again.

Improve again, be respectively arranged with the gusset plate of strengthening extension strength on the sidepiece of said extension tube.

Compared with prior art, the utility model adopts and divides two groups with outlet pipe, and per four cylinders are one group, and every group of outlet pipe is provided with pressurized machine.The advantage of this structure is: not only this venting gas appliance is made and assembly technology is simple, overall volume is little and cost is low; But also solved the problem of phase mutual interference between each cylinder exhaust effectively; Air inlet, the exhaust relation of motor (like diesel engine) have been improved; Make oil consumption lower and improved the problem of over-emitting black exhaust, improved the complete machine performance of diesel engine.In sum, the venting gas appliance of the utility model is improved to two pressurized machines by single pressurizator; Motor after the improvement efficiently solves the problem that acceleration seriously lags behind at full capacity, black smoke is big; Power further increases, and increases substantially maneuverability, has reduced the fuel oil fuel consumption; Make the engine operation performance better, more practical.
