Recycling.
In order to better understand the present invention, specific when the present invention works to valve control machanism below in conjunction with Fig. 1-Fig. 3
Operating condition is described in detail:
When engine is in suction stroke: the exhaust valve control mechanism control exhaust valve on right side is closed;Solenoid valve at this time
32 power-off, electromagnetic spring 33 fill in 35 by the top that elastic force pushes armature 34 and makes 34 lower end of armature and withstand high-pressure channel 221, simultaneously
High pressure oil inlet pipe 21 continues to inject high pressure liquid pressure oil into high-voltage oil cavity 22 and high voltage control oil pocket 23;At this moment, high-voltage oil cavity 22
It is interior in high pressure conditions and can not be by 221 pressure release of high-pressure channel, therefore high-voltage oil cavity 22 can only push down on valve plunger 13
Top, so that valve plunger 13 moves down;It is similarly in high pressure conditions in the upper oil cavitie of high voltage control oil pocket 23, but at this moment oils
Intracavitary hydraulic oil can enter lower oil cavitie by needle-valve pressure channel 134, and entered by lower oil cavitie and adjusted in oil pocket 31, make gas
The movement of door pillar plug 13 is smooth;When valve plunger 13 is displaced downwardly to the side for the inclined surface fitting lower oil cavitie for pushing rotary table 132, valve
The i.e. completely enclosed valve of plug, needle-valve pressure channel 134 is closed at this time and no longer pressure release, high-voltage oil cavity 22 and upper oil cavitie are kept
High pressure conditions withstand valve plunger 13, so that exhaust valve keeps pent state.
Meanwhile the intake valve control mechanism control intake valve in left side is opened;Solenoid valve 32 is powered and passes through magnetic at this time
Armature 34 is sucked power, and the top plug 35 on 34 top of armature leaves high-pressure channel 221, connects between high-voltage oil cavity 22 and adjusting oil pocket 31
It is logical;The hydraulic oil in high-voltage oil cavity 22 is entered by high-pressure channel 221 and is adjusted in oil pocket 31 at this time, the oil pressure in high-voltage oil cavity 22
Balance, the thrust no longer downward to valve plunger 13 of high-voltage oil cavity 22 are kept with the oil pressure for adjusting oil pocket 31;And enter high voltage-controlled
High pressure liquid pressure oil in liquefaction chamber 23 initially enters upper oil cavitie, then is entered in lower oil cavitie by needle-valve pressure channel 134, high at this time
The outlet of pressure control channel 231 is blocked by armature 34, therefore the oil pressure in lower oil cavitie increases and valve plunger 13 is pushed to move up, at this time
Valve plug 133 leaves valve 12, and when the oil pressure in lower oil cavitie keeps high pressure, valve plunger 13 can keep its position will not under
It moves, valve 12 when air inlet is prevented to be attracted valve plug 133.
After valve control machanism control exhaust valve is closed, intake valve is opened, the piston in cylinder is moved down,
Outside air is sucked in vacuum in cylinder and by intake valve and air inlet tracheae, completes the suction stroke of engine.
When engine is in instroke: the intake valve control mechanism control intake valve in left side is closed;It is electric at this time
Magnet valve 32 powers off, and electromagnetic spring 33 fills in 35 by the top that elastic force pushes armature 34 and makes 34 lower end of armature and withstands high-pressure channel 221,
High pressure oil inlet pipe 21 continues to inject high pressure liquid pressure oil into high-voltage oil cavity 22 and high voltage control oil pocket 23 simultaneously;At this moment, high pressure oil
In high pressure conditions and can not be by 221 pressure release of high-pressure channel in chamber 22, therefore high-voltage oil cavity 22 can only push down on valve plunger
13 top, so that valve plunger 13 moves down;High pressure conditions are similarly in the upper oil cavitie of high voltage control oil pocket 23, but at this moment
Hydraulic oil in upper oil cavitie can enter lower oil cavitie by needle-valve pressure channel 134, and entered by lower oil cavitie and adjusted in oil pocket 31,
Keep the movement of valve plunger 13 smooth;When valve plunger 13 is displaced downwardly to the side for the inclined surface fitting lower oil cavitie for pushing rotary table 132,
The i.e. completely enclosed valve 12 of valve plug 133, needle-valve pressure channel 134 is closed and no longer pressure release at this time, high-voltage oil cavity 22 and upper
Oil pocket keeps high pressure conditions, and valve plunger 13 is withstood, so that intake valve keeps pent state.
Meanwhile the exhaust valve control mechanism control exhaust valve on right side is opened;Solenoid valve 32 is powered and passes through magnetic at this time
Armature 34 is sucked power, and the top plug 35 of 34 lower end of armature leaves high-pressure channel 221, connects between high-voltage oil cavity 22 and adjusting oil pocket 31
It is logical;The hydraulic oil in high-voltage oil cavity 22 is entered by high-pressure channel 221 and is adjusted in oil pocket 31 at this time, the oil pressure in high-voltage oil cavity 22
Balance, the thrust no longer downward to valve plunger 13 of high-voltage oil cavity 22 are kept with oil pocket 31 is adjusted;And enter high voltage control oil pocket
High pressure liquid pressure oil in 23 initially enters upper oil cavitie, then is entered in lower oil cavitie by needle-valve pressure channel 134, because of high pressure control at this time
The outlet in channel 231 processed is blocked by armature 34, therefore the oil pressure in lower oil cavitie increases and keeps, so that valve plug 133 leaves valve
12 and the state that is held away from.
After valve control machanism control intake valve is closed, exhaust valve is opened, the piston in cylinder is moved up,
Exhaust gas after engine air in-cylinder combustion is discharged by exhaust valve and exhaust pipe, completes the instroke of engine.
Compared to existing valve control mode, valve control machanism operation of the invention is very reliable, can neatly, singly
Valve opening and closing are controlled, solely so as to which the air inlet gas of each timing is arbitrarily arranged in 4 valve timings of engine
Door and exhaust valve open or close perdurabgility, and the running parameter of each operating condition of engine is made all to meet optimum performance requirement,
It achieves energy-saving and emission reduction purposes.
Moreover, the position of valve plug is in the top of valve in valve control machanism provided by the invention, controlled in valve
Mechanism is exhausted or will not be since it is desired that the position of reserved valve plug generates gap and exhaust gas is caused not arrange all when air-breathing
Out, it so as to cause there are certain exhaust gas in cylinder in plug ignition, avoids in engine explosions stroke and explodes not enough
Thoroughly, the case where mixed gas burning in cylinder is not enough.Therefore, it this invention simplifies the structure of engine, mentions
The high efficiency of combustion of engine, alleviates the weight of engine and reduces the production cost of engine, finally effectively mention
The high economic performance of engine.
In conclusion the present invention provides a kind of engine air valve controlling mechanism, including valve mechanism, hydraulic mechanism and electricity
Magnetic mechanism, the valve mechanism include tracheae, the valve of connectivity trachea and the valve plunger for switching valve, the hydraulic press
Structure includes high pressure oil inlet pipe, high-voltage oil cavity and high voltage control oil pocket for pushing valve plunger, the top of the valve plunger
Portion is arranged in high-voltage oil cavity, and the middle part of valve plunger is arranged in high voltage control oil pocket, and the valve is arranged in valve plunger
