Description
Technical field
The present invention relates to field of internal combustion engine, particularly relate to internal combustion engine working process control, specifically one and relate to
Engine charge status adjustment and the novel air inlet path design improving air mass.
Background technology
The operating mode of electromotor is divided into the operating modes such as startup, idling, Smaller load, middle load, full load, acceleration and deceleration.Spark ignition
The formula electromotor amount of being adjustable type, i.e. carrys out the adaptation condition demand to output moment of torsion by change air inflow.In city, automobile
Most of the time is to operate under Smaller load and moderate duty operating mode.The feature of small engine load operating mode is engine speed
Low, throttle opening is little, 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 less, causes combustion mixture burning poor, and engine thermal efficiency is low and CO and HC discharge is the most serious.Cause
This, if the combustion mixture turbulence intensity entering cylinder when Smaller load is big, mixing the most abundant, the burning of combustion mixture is then
The most abundant, be more conducive to improving the thermal efficiency of electromotor.Electromotor uses tissue In Cylinder Flow to reach fuel and sky
The well-mixed purpose of gas.
Gas handling system is the important component part of electromotor, is responsible for providing gasoline combustion acting necessary fresh to cylinder
Air, in system, quality and the air flue design of air-flow are the most reasonable, have the biggest to electromotor performance and functional reliability etc.
Impact.The structure of air intake duct directly affects the size of fresh air charge in cylinder and sucks the intensity of air-swirl, and air inlet
Process enters the air capacity in cylinder and the VELOCITY DISTRIBUTION of gas and eddy current and turbulent flow conditions etc. significantly affect again combustion process,
Thus it is directly connected to burning sophistication, the composition of aerofluxus, waste gas utilisable energy and the operating economy of electromotor of electromotor
Property etc..The optimization of engine inlets flow behavior, can increase the strength of vortex in combustor, improve rate of flame propagation and
Burn rate, shortens combustion duration, thus improves dynamic property and the economy of electromotor, can also realize sub-load simultaneously
Lean-burn process under operating mode, improves the discharge performance of electromotor.Therefore to improve engine charge and fired state, it is necessary to
The air flue of design new structure, promotes the power performance of electromotor, makes burning more efficiently.
Formed in intake process is referred to as intake swirl around the organized air motion of cylinder-bore axis, and intake swirl pair
Significant in highly organized combustion process.The size of intake swirl is mainly by air intake duct shape and engine speed
Determine.In the method producing intake swirl, the inlet valve of band inducing QI screen is wherein used to force air to flow before inducing QI screen
Go out, rely on cylinder wall surface constraint, produce swirling eddy, improve the strength of vortex of charge air flow.And use tangential air flue produce into
During gas eddy stream, tangential air flue shape matching is straight, strong contraction before valve seating, guides air-flow to enter cylinder with tangential direction,
Thus cause the inhomogeneities of valve port VELOCITY DISTRIBUTION, be equivalent to, on the basis of even speed is distributed, increase by one tangentially
The speed in air flue direction, adds the circumferential disturbance of air-flow, but owing to valve circulation area is not fully utilized, the most applicable
In the electromotor requiring that intake vortex strength is the highest.And use the method for helical intake to be made by the valve intracavity above valve seating
Spiral type, makes air-flow be formed for the rotation of some strength in spirality channel, and at valve port, the situation of air-flow is equivalent to
On the basis of even speed is distributed, increases a tangential velocity, thus affect the flow regime of charge air flow, and then affect cylinder
Interior gaseous mixture distribution.
Summary of the invention
The problem that present invention mainly solves is the generation of electromotor intake swirl under actual motion middle-low load and strong to it
The enhancing of degree, by the structure that air intake duct is unique, four gas-distributing channels are tangentially connected on main airway, make to eventually enter into the sky of cylinder
Gas has stronger eddy current, promotes the mixing of oil gas, improves gaseous mixture distribution, makes burning more abundant, improves efficiency of combustion, reduce
Discharge.
In order to solve above-mentioned technical problem, a kind of the compound of engine charge eddy current that strengthen that the present invention proposes tangentially is entered
Air flue, including the air inlet being arranged on air storage chamber one end and the main airway connected with the air storage chamber other end, described air storage chamber is circle
Cylindrical cavity, described main airway is the cylindrical pipe connected with air storage chamber middle position, is disposed with multiple round main airway
Gas-distributing channel, described gas-distributing channel is a bend pipe, and one end of described bend pipe is through with the peripheral position of described air storage chamber, described bend pipe
The other end and described main airway are the most through by tangentially connected mouth;Described main airway is provided with the connection position of described air storage chamber
Main airway air throttle, described main airway air throttle is controlled by a rotary switch.
In the present invention, the number of described gas-distributing channel is 3~5, and preferably 4, multiple gas-distributing channels are uniform at circumferencial direction.
Described main airway air throttle is a circular slab that can rotate around rotary switch, and the external diameter of described circular slab is interior with described main airway
Footpath coordinates.Described air inlet and the junction of described air storage chamber, described main airway and the junction of described air storage chamber, described point of gas
Road is fillet design with the junction of described air storage chamber.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention design by Novel gas passage structure, takes different air inlets respectively when electromotor different load: low
During load, air inlet mainly indirectly enters main airway from gas-distributing channel, to charge air flow Additional rotation angle momentum, increases intake swirl
Intensity, promotes the good mixing of oil gas, improves burning quality, reduce fuel consumption, reduce discharge, promote simultaneously outside cylinder
Flow rotation, it is to avoid the problem that in the design of original tangential air flue, valve flow area is not fully utilized;During moderate duty
It is gradually increased the circulation area of main airway by controlling rotary switch, makes air inlet enter burning from main airway and gas-distributing channel simultaneously
Room, can meet the needs that air inflow increases, can improve again intake vortex strength;During high load capacity, major part air is directly from main gas
Road enters, and reduces intake resistance, it is ensured that air quantity delivered, it is ensured that the power output of electromotor.The reality of two kinds of various inlet schemes
Execute, the burning quality of electromotor when can improve underload, reduce oil consumption and discharge, can guarantee that again power during high load capacity simultaneously
