Description
Technical field
The present invention relates to inlet manifold technical fields, more particularly, to a kind of attachment tube structure of inlet manifold.
Background technique
Currently, the engine of automobile is just towards miniaturization, integrated lightweight with the continuous of automobile emission regulation plus sternly
Direction develop, while the technology of some engine emissions that can be reduced also increasingly is started by Main Engine manufacturer and entirely
The attention of machine industry.Key components and parts of the gas car engine inlet manifold as gas handling system, it is integrated in order to meet lightweight
Requirement, it is however generally that, each automobile vendor all can be by crankcase ventilation system, canister adsorption system, gas recirculation system
Interface integration in inlet manifold, and fifty-fifty imported by several air flues of inlet manifold the combustion chamber of engine
It is interior, the burning of engine is participated in air-fuel mixture gas.In order to meet engine emission requirements, engine crankcase will be come from
The machine oil of ventilating system and the mixed gas of engine chamber gas blowby, the fuel-steam from canister adsorption system carry out exhaust gas
The exhaust gas generated when the engine combustion of recirculating system equably imported into the burning of engine via the air flue of inlet manifold
Room becomes more important, the especially gas of exhaust gas recycling.And the position of this this interface, and specific shape all can be right
The uniformity of gas distribution generates vital influence.Because inlet manifold in development process, also needs air throttle method in future
Blue gas is uniformly distributed in each air flue.So if the position of this interface tube to be embedded in the trunnion near air throttle
On, and ensure to enter the gas flow of inlet manifold and be flowed into from throttle body under the gas unanimous circumstances of tracheae air flue,
It can better ensure that the gas from interface flows uniformly into each cylinder of inlet manifold.
Since the temperature of egr gas is higher, so will generally be given up from engine high-temperature by a metal tubulation
Gas is imported into inlet manifold, is reserved in corresponding mounting hole so one end of metal tube is inserted into inlet manifold, and
A upper O-ring is covered for sealing in one end of metal tube；Later by the flange of fixed metal tube one end, thus by metal tube
One end be fixed on mounting hole, prevent it from loosening, specifically, be with screw pass through flange on installation via hole, flange is consolidated
It is scheduled on the mounting hole of inlet manifold.This class formation designs the limitation for the supporting and space that limited inlet manifold can be provided, periphery
Exhaust gas can only be flowed to vertical direction and imported into air inlet discrimination by the limitation of installation space along with from throttle body live gas
Pipe, this design are unfavorable for evenly distributing for exhaust gas.And have to become larger the diameter of conduit to preferably distribute gas, into
And occupy more spaces.
Summary of the invention
It is attached it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of inlet manifold
Belong to pipe structure.
The purpose of the present invention can be achieved through the following technical solutions:

Circle.
Preferably, the inlet end that the exhaust gas enters pipe forms exhaust gas entrance, exhaust gas enters the two sides of pipe in open-like shape
Equipped with fixing screwed hole.
Preferably, the exhaust gas enters the inlet end of pipe in ozzle shape.
The operation principle of the present invention is that:
For from gas flow, the live gas in the induction stroke of engine from air filter enters via air throttle
To the junction of itself and inlet manifold throttle flange, later after inlet throat, into inlet manifold pressure stabilizing cavity, then
Multiple inlet manifold air flues are entered evenly；From gas recirculation system, crankcase ventilation system and canister adsorption system
Exhaust gas is first entered by the exhaust gas entrance that exhaust gas enters pipe, later by air guide entrance, and changes gas flow by air guide bend pipe
Afterwards, inlet throat is flowed by multiple waste gas outlets, is arranged in after inlet manifold pressure stabilizing cavity as live gas uniformly flows into
Multiple inlet manifold air flues.
Structurally, air guide bend pipe of the invention is installed together by bend pipe guide plate and bend pipe guide groove, and
After inlet manifold installs air throttle, it is crushed on the mounting plane of throttle flange, realizes fixation.
Compared with prior art, the invention has the following advantages:

Even property can be adapted for the exhaust gas of any direction importing.
(2) easy for installation: intake elbow is encased in air inlet by guide groove and guide plate structure of the invention in a manner of more easy
On manifold.
(3) use scope is wide: can adapt to the exhaust gas from not homologous ray by the structure type of exhaust gas entrance herein and lead
Enter.Both fixing screwed hole can be used, by threaded screw, gas recirculation system, crankcase ventilation system and carbon will be come from
The exhaust gas metal tube or hard tube of tank adsorption system are fixed on exhaust gas entrance, can also be led to by exhaust gas entrance using after ozzle
It crosses clip to secure the hose on ozzle, or leads to fast connection interface for hose clamp on exhaust gas entrance.
(4) structure is simple: the present invention dexterously carries out air guide bend pipe by by the process of air throttle installation inlet manifold
Final fixation.
(5) manufacturing cost is low: since air guide bend pipe is to install in inlet manifold in the later period, therefore can use plastics or metal
Material is manufactured, and can be processed into standard component according to demand, more to reduce generation manufacturing cost.
