Description
Technical field
The present invention relates to a kind of intensive locking-type multi-mode lever Variabale valve actuation systems, belong to engine valve
Drive area.
Background technique
With energy and environmental problem get worse and people's being absorbed in the driving of vehicle and safety, not
Carry out engine to need under the premise of meeting discharge index, comprehensively considers dynamic property, economy, emission performance and safety.This is just
It needs driving and braking within the scope of full working scope, optimizes engine performance.And changeable air valve, the stroke changeable being concerned at present
The technologies such as number, cylinder deactivation, auxiliary braking, new combustion mode, variable compression ratio, variable EGR are only transported in engine small range mostly
Its performance is improved in row conditioned area.As existing changeable air valve technology is only applied to the drive in fixed punch number of passes engine
It starts building under condition, and is mostly used for the inlet valve of gasoline engine to reduce pumping loss.Stroke changeable number technology is still in both at home and abroad
Conceptual phase, and be served only under driving operating condition.The existing vehicle with cylinder stopping technique can only provide cylinder deactivation, therefore, right
Consumption improvement degree is relatively low, can only obtain 8% or so oil consumption mostly and reduce.On the other hand, with the urgency of engine ownership
Increase severely and add, vehicle safety is increasingly valued by people, and auxiliary braking system is classified as vehicle by more and more countries must
One of standby attachment.However at present auxiliary braking system exist mostly brake component work long hours be easy overheat, braking efficiency
Quickly reduce, braking efficiency controllable degree is low, braking when vehicle is easy sideslip, braking system occupies limited vehicle space etc. and asks
Topic.In current engine auxiliary braking technology, the braking effect for depressurizing auxiliary braking technology is best, but it is in intake and exhaust
Door operating condition is constant, realizes that pressure m is imitated near to open exhaust valve or pressure reducing valve compared with small guide vane
Fruit, the every 720 ° of crank angles of engine realize a braking cycle, belong to the braking of four strokes, and braking effect is unable to satisfy vehicle
Requirement when heavy load is braked.
Aiming at the problem that above-mentioned engine research field, Dalian University of Technology's Internal Combustion Engine institute burning seminar is based on
The thought of partition zone optimizing engine performance, proposes a kind of multimode engine within the scope of driving braking full working scope, and provides each
The requirement using operating condition and to the valve opening and closing moment of kind mode: under the driving operating condition of low speed and heavy load, using two-stroke
Drive mode, to achieve the purpose that improve power output；Under other engine driving operating conditions, using four stroke drive modes,
To achieve the purpose that reduce fuel consumption and emission formation；Under heavy load damped condition, using two-stroke braking mode, with
Achieve the purpose that improve braking power output；Under small load brake operating condition, using four stroke braking modes, according to deceleration loading
Requirement, change the number of stroke of braking mode adjust braking output, with achieve the purpose that improve vehicle safety.
Currently, practical Variabale valve actuation system remains valve cam mostly, using mechanical structure, mainly
It is divided into: 1) camshaft phase modulation formula, such as VVT system, the Vanos system of BMW of TOYOTA；2) lift range variable stage by stage
Formula, such as the VTEC system of Honda；3) continuously variable valve lift formula, such as the Valvetronic system of BMW, Hyundai
CVVL system etc..This kind of system realizes the opening and closing timing and maximum row of each cylinder valve of engine by control intermediate transmission mechanism
The synchronous adjustment of Cheng Sanzhe.
For relatively having cam Variabale valve actuation system, system without cam can realize more flexible valve event, simultaneously
Structure is complicated, expensive, and needs more to be deepened in terms of reliability, durability and valve temperature compensation
The research entered.This kind of system mainly includes two class of electromagnetic type and electric-liquid type.Electromagnetic type system is in the accurate control of movement, valve stroke
Adjustable degree etc. remains to be further improved.For electromagnetic type system, electric-liquid type system has relatively higher valve can
The features such as adjusting flexibility ratio, higher power density, flexible arrangement is Variabale valve actuation system most potential at present.This is
System mainly includes common rail oil feeding type and cam oil feeding type two major classes.
Common rail oil feeding type system eliminates valve cam, drives oil in the open/close states and accumulator by controlling solenoid valve
Pressure, adjust the opening and closing timing and range of valve.Ford company, Lucas company etc. carried out research to this, still needed to
System cost, response speed, occupied space etc. carry out in-depth study.With engine cylinder number single cylinder valve number and turn
The increase of speed, the system there is also: a) the problem of common rail pipe bulky difficulty in arrangement；B) high speed used in system
The quantity of big flow solenoid valve is excessive, and the solenoid valve higher cost determined by current solenoid valve material and processing technology, because
This, the overall cost of the system is higher.These problems cause traditional common rail oil feeding type system automobile-usedization more difficulty, this kind of system
System is widely used on the exhaust valve of low speed two stroke engine peculiar to vessel.
By the advantage of comprehensive mechanical formula and common rail oil feeding type system, cam oil feeding type system receives researcher and Sheng
Produce the extensive concern of manufacturer, such as Multiair system, the VCM system of ABB of FIAT.This kind of system is supplied using cam post plug
Oily device replaces accumulator, occupy little space, it can be achieved that the opening and closing timing of valve it is separately adjustable, opening and closing timing determines and row
Journey.There is still a need for improved in terms of following two for this kind of system: a) quantity of oil feeder and solenoid valve needed for system is more, is
Overall cost of uniting is higher；B) valve operation adjustable extent is limited by fuel feeding and control device, cannot achieve valve opening and closing just
When and stroke three between it is separately adjustable, engine two-stroke drive mode and two-stroke braking mode requirement also cannot be achieved
360 °C of A/ circulation valve operational process etc..
Since the Variabale valve actuation system of existing functionization is mostly used for the engine of four stroke drive modes, Bu Nengman
The requirement of sufficient multimode engine, therefore develop a set of high reliablity and meet the variable valve actuation of multimode engine requirement
System is imperative.Engine two-stroke drive mode, four stroke drive modes, two-stroke braking mode and the braking of four strokes
Under mode, there is greatly difference in import/exhaust door open frequency, unlatching timing and unlatching duration, which greatly increases
The development difficulty for the Variabale valve actuation system that multimode engine requires.Such as due to two-stroke drive mode or two-stroke system
Dynamic model formula requires inlet and exhaust valve every 360 ° of crank angles operation primary, four stroke drive modes and four stroke braking modes require into
The every 720 ° of crank angles operation of exhaust valve is primary, it is therefore desirable to need to realize that two-stroke driving/braking mode and four strokes are driven
The spirit between both valve running frequencies may be implemented in the multi-mode Variabale valve actuation system switched between dynamic/braking mode
Switching living.Under same mode, working conditions of different engines requires valve-driving system to be capable of providing different import/exhaust door unlatchings
Timing, maximum lift and unlatching duration, it is therefore desirable to the valve-driving system of flexibility and changeability.There has been no a variable gas at present
Door drive system can meet requirements above simultaneously, therefore the exploitation of multi-mode Variabale valve actuation system is extremely urgent.
