Description
Technical field
The present invention relates to automotive engine applications, and in particular to a kind of automotive engine valves control method.
Background technology
Vehicular engine in order to meet necessary power reserve, can using multi-cylinder, work improves discharge capacity side by side, but due to
Discharge capacity the Nature can bring high oil consumption, and when for vehicle zero load, strong impetus is not needed in urban road stop-go
When, the full cylinder working of multicylinder engine just seems to be wasted very much.Therefore, some cylinders are closed during sub-load to bear to improve engine
Lotus rate, it is most simple and effective fuel saving method.But if cylinder deactivation oil-break, due to the appearance of pumping loss so that
Oil-saving effect unobvious.To keep valve to close all the time during cylinder deactivation for this, in the prior art, cylinder deactivation valve can not be realized
High frequency, close at a high speed, cylinder deactivation in turn can not be realized for this, in order to reduce the inequality during cylinder deactivation in existing cylinder stopping technique
Weighing apparatus, it is necessary to complicated transformation is carried out to engine, even if so also having larger vibrations and noise, long-term use of cylinder deactivation mould
Formula can also make it that each cylinder friction is uneven, and crankshaft torsion and block distortion can be caused if serious.
The content of the invention
First, technical problems to be solved
How valve is reasonably controlled so as to effectively realize cylinder deactivation engine in turn.
2nd, technical scheme
In view of the above-mentioned problems existing in the prior art, spy provides a kind of valve controlling party of cylinder deactivation engine in turn to the present invention
Method, the valve control method are implemented by following controlling organizations, and the controlling organization includes：Tappet (11), positioned at tappet
(11) lower section is used to drive the cam (12) of tappet (11) up and down motion, the push rod being vertically arranged on tappet (11), is installed on
Conduit (10) in cylinder head, the valve (9) being slidably mounted in conduit (10) and by the rotatably mounted gas of rotating shaft (2)
Door rocking arm (4), one end of the valve rocker (4) are rotationally connected with the top of push rod (1), the valve rocker (4) it is another
One end be located at the surface of valve (9) and swing to lower section valve rocker (4) be mutually not in contact with each other with valve (9), the valve
(9) top is provided with cotter seat (7), and valve spring (8) is plugged on valve (9) and its both ends is fastened in valve bullet respectively
Between spring abutment (7) and conduit (10), in addition to one kind is used to contact or not connect with valve (9) when controlling valve rocker (4) to swing
Tactile valve control apparatus；The valve control apparatus includes the electromagnet (6) for being horizontally installed to valve (9) side, the electricity
The head end of magnet (6) is provided with support slipper (5), is provided with lug boss protruding upward on the support slipper (5), works as projection
When portion is located between valve rocker (4) and valve (9), valve (9) is depressed in the valve swing arm (4) for swinging to lower section；
The valve control method comprises the following steps：
When valve (9) normal work, valve control apparatus control electromagnet (6), the branch for installing electromagnet (6) head end
The boss set on sliding block (5) is supportted between valve rocker (4) and valve (9), now cam (12) driving push rod (11)
Forward direction is swung, and valve rocker (4) dextrorotation is touched support slipper (5), opens valve (9)；When needing cylinder deactivation, in corresponding gas
When the valve rocker (4) of cylinder reversely rotates unlatching certain gap, valve control apparatus control electromagnet (6) moves right, and pulls
Support slipper (5) completion moment is moved right, and now, cam (12) driving push rod (11) is positive to be swung, and makes valve rocker (4) just
Rotation still can not touch support slipper (5), can not also open valve (9).
3rd, beneficial effect
Compared with prior art, i.e., valve control method provided by the invention can be with more efficient accurately control valve opening
Open and close, improve the efficiency of cylinder deactivation of engine, and the method also effectively reduces the pumping loss during cylinder deactivation,
Brief description of the drawings
Fig. 1 is the valve operation status architecture schematic diagram of the present invention；
Fig. 2 is the valve stop working state structural representation of the present invention；
In figure, the gas of 1. push rod, 2. rotating shaft, 3. rocker-arm return spring, 4 valve rocker, 5. support slipper, 6. electromagnet 7.
The cam of 11. tappet of door spring base 8. valve spring, 9. valve, 10. conduit 12..
Embodiment
Below in conjunction with the accompanying drawings 1, the present invention will be further described for accompanying drawing 2.
The valve control machanism of this cylinder deactivation engine in turn, including tappet 11, positioned at the lower section of tappet 11 be used to drive tappet
11 move up and down cams 12, be vertically arranged on tappet 11 push rod, be installed in cylinder head conduit 10, be slidably mounted on
Valve 9 in conduit 10 and rotatably connected by the rotatably mounted valve rocker 4 of rotating shaft 2, one end of the valve rocker 4
The top of push rod 1 is connected to, the other end of the valve rocker 4 is located at the surface of valve 9 and swings to the valve rocker 4 of lower section
Be not in contact with each other with the phase of valve 9, the top of valve 9 is provided with cotter seat 7, valve spring 8 be plugged on valve 9 and its two
End is fastened between cotter seat 7 and conduit 10 respectively, in addition to one is used to connect with valve 9 when controlling valve rocker 4 to swing
Tactile or discontiguous valve control apparatus.When valve normal work, valve control apparatus can make the driving push rod 1 of cam 12 just
To unlatching valve 9 when swing.When cylinder deactivation is needed, valve control apparatus causes valve swing arm 4 not connect with valve 9
Touch, when valve rocker 4 moves down, valve remains closed mode.So as to realize that cylinder deactivation valve is not protected by actuated by cams
Closed mode is held, reduces pumping loss.
Above-mentioned valve control apparatus includes the electromagnet 6 for being horizontally installed to the side of valve 9, the head end peace of the electromagnet 6
Equipped with support slipper 5, lug boss protruding upward is provided with the support slipper 5, when boss is in valve rocker 4 and gas
When between door 9, valve 9 is depressed in the valve swing arm 4 of the lower section of swing.When cylinder deactivation is needed, in the valve of corresponding cylinder
Rocker arm 4 reversely rotates electromagnet 6 when opening certain gap and pulls the completion moment of support slipper 5 to move right, valve rocker 4
And then dextrorotation still can not touch support slipper 5, can not also open valve 9.What cam 12 " near to stop " was smoothed out machines away one
Part, so when tappet 11 is in 12 near angle of repose of cam, continued by push rod 1 and the push rod 1 of return spring 3
Certain angle is reversely rotated, so that a gap between support slipper 5 and valve Rocker arm 4 be present, at this moment, support
Sliding block 5 moves right would not be by too big resistance.During cylinder deactivation, using this gap, the moment of electromagnet 7 pulls support
Sliding block 5 moves to right, and cam 12 drives valve Rocker arm 4 is positive to swing the supporting role for losing support slipper 5, can not open valve 9.
It is not that valve 9 is turned on or off by external force due to the valve control machanism of the design, but catches the motion of valve to advise
Rule, by jack supporting role, the driving force of electromagnet 6 that it requires is very low, it is easy to realizes that high-speed high frequency is moved, so as to real
Cylinder deactivation is in turn showed.
