Description

Inlet manifold

Technical field

The utility model is related to logical machine accessory technical field, in particular to a kind of inlet manifold.

Background technology

Logical machine, i.e. universal machine, are typically now referred to gasoline engine or diesel engine and are set using its machinery as power Standby, when work, is introduced the fuel into cylinder, and fuel and air is made to burn in cylinder, generates high temperature and pressure, and gas is drastically swollen Swollen promotion piston motion so as to export power, externally does work.

In order to the fuel in cylinder is made fully to react, need effectively to input air in cylinder, it is existing logical Machine is respectively provided with gas handling system.In general, gas handling system includes air inlet pipe, air cleaner, air throttle and inlet manifold.Air Air cleaner is entered by air inlet pipe under the action of internal pressure, reaches air throttle, then flows into inlet manifold and fuel mixture Mixing, finally flows into cylinder.

Inlet manifold includes air inlet pipe and air outlet pipe, and the number of air outlet pipe corresponds to the cylinder number of engine, and be mostly Arranged in a straight line, in order to save space, the air inlet pipe trend of usual inlet manifold is parallel with the orientation of air outlet pipe, therefore air There is the transformation of flow direction during entering air outlet pipe by air inlet pipe, influence the intake uniformity of each air outlet pipe, air can not be made It is sufficiently mixed with fuel mixture, in turn results in that each cylinder working of engine is uneven, strong influence the effective defeated of engine Go out power and torque, it is also possible to influence the service life of engine.

Utility model content

The utility model is intended to provide a kind of inlet manifold, and it is uneven can to solve each air outlet pipe air inlet of existing inlet manifold The problem of.

In order to solve the above-mentioned technical problem, this patent provides following basic technology scheme：

Inlet manifold, including manifold body, the manifold body is equipped with air outlet pipe, and air inlet is additionally provided in manifold body Chamber, the side wall of the inlet chamber are equipped with air inlet, are equipped with gas outlet on the position opposite with air inlet on inlet chamber side wall, The number of gas outlet is identical with air outlet pipe, and gas outlet is connected with air outlet pipe, and the kicker baffle of taper is equipped between gas outlet, described Gas outlet and air outlet pipe are symmetrical arranged along the connecting line at inlet chamber center and air inlet, baffle are equipped at air inlet, on baffle Equipped with equally distributed through-hole.

In technical solutions of the utility model, air inlet reduces stream when air enters in air outlet pipe with gas outlet opposition setting To transformation, the presence of inlet chamber can also play air-flow cushioning effect, and baffle can also reduce air velocity, and then reduce stream The influence brought to transformation and air-flow collision to gas homogeneity；On baffle equally distributed through-hole can make air-flow uniformly into Enter into inlet chamber, air-flow can be evenly distributed in the gas outlet of both sides by the kicker baffle of taper, cooperation gas outlet with And air outlet pipe is symmetrical arranged along the connecting line of inlet chamber and air inlet and may further ensure that gas in the air outlet pipe of connecting line both sides The uniformity of body flow.

Further, fan is equipped in the inlet chamber, the fan can rotate under the promotion of air-flow.

Fan is pushed to rotate by air-flow, the flabellum of rotation can be such that air is mixed more between being mixed with fuel mixture Fully.

Further, the manifold body is equipped with otic placode, and the otic placode is equipped with mounting hole.

Can inlet manifold be fixedly mounted by the mounting hole on otic placode.

Further, it is equipped with ring flange on the outlet pipe end and air inlet.

By ring flange, inlet manifold can be made to be bonded with other inlet channel components.

Further, the material of the manifold body and air outlet pipe uses metallic aluminum material.Processing cost is low.
