Description
Technical field
The present invention relates to field of internal combustion engine, control more particularly to internal combustion engine working process, specifically one kind is related to
Engine charge status adjustment and the novel air inlet path design for improving air mass.
Background technique
The operating condition of engine is divided into the operating conditions such as starting, idling, Smaller load, middle load, full load, acceleration and deceleration.Spark ignition
The formula engine amount of being adjustable type adapts to demand of the operating condition to output torque by changing air inflow.In city, automobile
Most of the time is operated under Smaller load and moderate duty operating condition.The characteristics of small engine load operating condition is engine speed
It is low, throttle opening is small, induction air flow ratio is low, so the atomization mixing condition of injected fuel spray and oil film is poor, and engine cylinder
Interior turbulence intensity is smaller, causes combustion mixture burning poor, and engine thermal efficiency is low and CO and HC discharge is more serious.Cause
This, if the combustion mixture turbulence intensity for entering cylinder in Smaller load is big, mixing it is more abundant, the burning of combustion mixture is then
It is more abundant, be more conducive to the thermal efficiency for improving engine.Engine mostly uses tissue In Cylinder Flow to reach fuel and sky
The well-mixed purpose of gas.
Gas handling system is the important component of engine, is responsible for providing to cylinder fresh necessary to gasoline combustion acting
Air, whether the quality and air flue design of system interior air-flow are reasonable, have to engine performance and functional reliability etc. very big
Influence.The structure of air intake duct directly affects the intensity of the size of fresh air charge in cylinder and sucking air-swirl, and air inlet
The VELOCITY DISTRIBUTION and vortex and turbulent flow conditions etc. of air capacity and gas that process enters in cylinder significantly affect combustion process again,
To be directly related to the burning sophistication of engine, the operating economy of the ingredient of exhaust, exhaust gas utilisable energy and engine
Property etc..The optimization of engine inlets flow behavior, can increase the vortex intensity in combustion chamber, improve rate of flame propagation and
Burn rate shortens combustion duration, to improve the dynamic property and economy of engine, while can also realize sub-load
Lean-burn process under operating condition, improves the emission performance of engine.Therefore in order to improve engine charge and combustion state, it is necessary to
New structural air flue is designed, the power performance of engine is promoted, makes burning more efficiently.
What is formed in intake process is known as intake swirl around the organized air motion of cylinder-bore axis, and intake swirl pair
It is of great significance in highly organized combustion process.The size of intake swirl mainly by air inlet road shape and engine speed and
It determines.In the method for generating intake swirl, wherein being flowed before air guide screen using the inlet valve forced air with air guide screen
Out, it is constrained by cylinder wall surface, generates swirling eddy, improve the vortex intensity of charge air flow.And using tangential air flue generate into
When gas eddy stream, tangential air flue shape is more straight, the strong contraction before valve seating, and air-flow is guided to enter cylinder with tangential direction,
It to cause the inhomogeneities of valve port VELOCITY DISTRIBUTION, is equivalent on the basis of even speed distribution, increases by one tangentially
The speed in air flue direction, increases the circumferential disturbance of air-flow, but since valve circulation area is not fully utilized, is only applicable in
In the engine for requiring intake vortex strength not high.And the method for helical intake is used to be made into the valve above valve seating is intracavitary
Spiral shape makes air-flow just form the rotation of some strength in spirality channel, is equivalent to the case where air-flow at valve port
On the basis of even speed distribution, increase a tangential velocity, to influence the flow regime of charge air flow, and then influences cylinder
Interior gaseous mixture distribution.
Summary of the invention
Present invention mainly solves the problem of be under actual motion middle-low load the generation of engine intake swirl and to its it is strong
The enhancing of degree, by the unique structure of air intake duct, four gas-distributing channels are tangentially connected on main airway, make the sky for eventually entering into cylinder
Gas has stronger vortex, promotes the mixing of oil gas, improves gaseous mixture distribution, keeps burning more abundant, improve efficiency of combustion, reduces
Discharge.
In order to solve the above-mentioned technical problem, one kind proposed by the present invention can enhance engine charge vortex it is compound tangentially into
Air flue, including the main airway that the air inlet of air storage chamber one end is arranged in and is connected to the air storage chamber other end, the air storage chamber is circle
Cylindrical cavity, the main airway are the cylindrical pipe being connected to air storage chamber central location, are disposed with around main airway multiple
Gas-distributing channel, the gas-distributing channel are a bend pipes, and one end of the bend pipe and the peripheral position of the air storage chamber penetrate through, the bend pipe
The other end is tangentially penetrated through with the main airway by tangentially connected mouth；The connection position of the main airway and the air storage chamber is equipped with
Main airway air throttle, the main airway air throttle are controlled by a rotary switch.
In the present invention, the number of the gas-distributing channel is 3~5, and preferably 4, multiple gas-distributing channels are uniformly distributed in circumferencial direction.
The main airway air throttle is a circular slab that can be rotated around rotary switch, and the outer diameter of the circular slab is interior with the main airway
Diameter cooperation.The junction of the air inlet and the air storage chamber, the main airway and the air storage chamber junction, described divide gas
The junction of road and the air storage chamber is fillet design.
Compared with prior art, the beneficial effects of the present invention are:
The present invention passes through the design of novel gas passage structure, takes different air inlets respectively in engine different load: low
Air inlet mainly enters main airway from gas-distributing channel indirectly when load, to charge air flow Additional rotation angle momentum, increases intake swirl
Intensity promotes the good mixing of oil gas, improves burning quality, reduces fuel consumption rate, reduces discharge, while promoting outside cylinder
Flow rotation avoids the problem of valve flow area is not fully utilized in original tangential air flue design；When moderate duty
It is gradually increased the circulation area of main airway by control rotary switch, air inlet is made to enter burning from main airway and gas-distributing channel simultaneously
Room, had not only been able to satisfy the needs of air inflow increase, but also can improve intake vortex strength；Major part air is directly from main gas when high load capacity
Road enters, and reduces intake resistance, guarantees air supply amount, guarantees the power output of engine.The reality of two kinds of various inlet schemes
Power when applying, the burning quality of engine when can improve underload, reduce oil consumption and discharge, while can guarantee high load capacity again
