Abstract
The invention relates to a double-coil electric air valve. The double-coil electric air valve is composed of an air valve body, an air valve guide pipe, an air valve spring, a spring base, a round armature, an upper coil, a lower coil, a coil driver and a microprocessor. The upper coil and the lower coil wind the same frame, are fixed on a cylinder cover and are driven by the coil driver, and a signal driven by the coil driver is controlled by the microprocessor. The spring base is fixed in the middle section of an air valve rod, the air valve spring is acted between the cylinder cover and the spring base, the elasticity of the air valve spring is far less than the force of an air valve spring of an existing internal combustion engine, the function of the air valve spring is to close the air valve body when an internal combustion engine stops working, the round armature is fixed on the upper section of the air valve rod and is assembled in an inner hole of the upper coil and an inner hole of the lower coil, and the round armature is driven by the electromagnetic force to drive the air valve body to move up and down. The microprocessor can achieve the purpose of adjusting the opening stroke of the air valve body by controlling the current ratio of the upper coil and the lower coil. Compared with the method that the stroke of the air valve body is adjusted in a mechanical mode, the double-coil electric air valve has the advantages that a complex rocker mechanism is removed, the structure is simple, and total stroke is adjusted in a stepless mode.
Description
Technical field
The present invention relates to the stroke adjustable electric valve that internal-combustion engine uses.
Background technique
The stroke adjustable valve of prior art adopts machinery type adjustment stroke more, has the limited technical problem of complex structure and regulated quantity.The present invention adopts and changes the technological scheme that twin coil current ratio regulates valve stroke, has solved said structure complexity and the limited technical problem of regulated quantity.
Summary of the invention
The technical solution adopted for the present invention to solve the technical problems is: a kind of twin coil electric air valve is pressed iron, upper coil, lower coil, coil actuator, microprocessor by valve, valve guide bushing, valve spring, spring seat, garden and formed; Upper coil and lower coil are on same skeleton and be fixed on cylinder head, and upper and lower coil is driven by coil actuator, and the signal of its driving is controlled by microprocessor; Valve guide bushing tightly fits in the hole, garden of cylinder head, and valve guide bushing endoporus is in moving the cooperation for valve guiding of valve stem of valve, and spring seat is fixed on the stage casing of valve stem, and ferropexy is pressed at the epimere of valve stem in garden; Valve spring acts between cylinder head and spring seat, but elastic force is much smaller than the valve spring power of existing internal-combustion engine, its effect is that internal-combustion engine cuts out valve while quitting work, and press in the endoporus that iron is assemblied in coil and lower coil in garden, and under the effect of electromagnetic force, the sheet iron strip upper and lower motion of door of taking offence is pressed in garden.
Twin coil electric air valve working principle is: when upper coil obtains when electric, electromagnetic force Shang La presses in garden iron makes valve close (top dead center); When lower coil obtains when electric, iron is pressed in the drop-down garden of electromagnetic force, and to overcome valve spring power descending, makes valve opening to range (lower dead center); When upper and lower coil simultaneously when electric, its synthetic electromagnetic force, makes valve opening to 1/2 stroke; If change the current ratio of upper and lower coil, valve opening stroke also can correspondingly change.Therefore, only the upper and lower coil current of different strokes need be stored in microprocessor than data, microprocessor can, by changing the current ratio of upper and lower coil, reach the object of omnidistance step-less adjustment valve opening stroke.
Beneficial effect of the present invention:
1, mechanical structure is succinct, has saved baroque rocker arm body.
2, can omnidistance step-less adjustment valve stroke.

In Fig. 1,1. valve, 2. valve guide bushing, 3. cylinder head, 4. valve spring, 5. spring seat ,6. press in garden iron, 7. lower coil, 8. go up coil, 9. coil actuator, 10. microprocessor
Embodiment:
A kind of twin coil electric air valve is pressed iron, upper coil, lower coil, coil actuator, microprocessor by valve, valve guide bushing, valve spring, spring seat, garden and is formed; Upper coil and lower coil are on same skeleton and be fixed on cylinder head, and upper and lower coil is driven by coil actuator, and the signal of its driving is controlled by microprocessor; Valve guide bushing tightly fits in the hole, garden of cylinder head, and valve guide bushing endoporus is in moving the cooperation for valve guiding of valve stem of valve, and spring seat is fixed on the stage casing of valve stem, and ferropexy is pressed at the epimere of valve stem in garden; Valve spring acts between cylinder head and spring seat, but elastic force is much smaller than the valve spring power of existing internal-combustion engine, its effect is that internal-combustion engine cuts out valve while quitting work, and press in the endoporus that iron is assemblied in coil and lower coil in garden, and under the effect of electromagnetic force, the sheet iron strip upper and lower motion of door of taking offence is pressed in garden.Only the upper and lower coil current of different strokes need be stored in microprocessor than data, microprocessor can, by changing the current ratio of upper and lower coil, reach the object of omnidistance step-less adjustment valve opening stroke.Twin coil electric air valve of the present invention is specially adapted to load internal-combustion engine complicated and changeable.
