Abstract
A combination valve mechanism of an engine comprises an air intake system and an exhaust system, wherein the air intake system is driven electromagnetically and the exhaust system is driven by a cam. The number of parts of the engine can be reduced, rotating speed is increased rapidly, power is improved, energy consumption is reduced, and modularization and miniaturization of the engine are easy to achieve.
Description
Technical field
The utility model belongs to internal combustion engine technologies field, relates to engine valve actuating mechanism.
Background technique
Engine valve actuating mechanism is the work cycle requirement according to cylinder, and in time opening and closing inlet and outlet door in time enters cylinder acting to meet inflammable mixture, and waste gas is successfully discharged cylinder in good time.
Conventional distribution device is that bent axle passes through timing chain or Timing Belt drive cam shaft at present, by actuated by cams inlet and outlet door, to meet cylinder inlet and outlet requirement.In order to make motor Maximum Power Output under various rotating speeds, designed port timing, designed variable valve timing and gas-distributing mechanism, be convenient to cylinder and can enter more fresh air, owing to limited by the changeover portion of cam profile, along with engine speed improves, just inevitably there is cylinder charge deficiency and the unclean phenomenon of exhaust, engine power performance, Economy are declined.
Also having a class is electromagnetic air valve, principle is to be that electromagnetic force drives valve by electric energy conversion, open valve speed fast, aperture is large, air inflow is many, improved the power of motor, the problem existing: when exhaust stroke, in cylinder, be the pressurized gas after burning, as adopt Electromagnetic Drive exhaust valve, overcome gas pressure in cylinder and the pre-tightening tension sum of exhaust valve spring, for reaching requirement, increase electromagnetic coil volume, be unfavorable for like this motor miniaturization, coil is also difficult to layout, increase coil current, restricted by material, power consumption increases.
Summary of the invention
In order to solve above deficiency, the utility model proposes solution and be: the distribution device being combined by two kinds of drive forms.
Gas handling system, by Electromagnetic Drive, comprises sensor, controller, electromagnetic coil module, intake valve, intake valve conduit, the compositions such as inlet-valve spring.
Vent systems is by traditional timing chain, camshaft, cam, rocking arm, exhaust valve, exhaust valve guide, the compositions such as exhaust valve spring.
When intake stroke, exhaust valve closes, pressure in cylinder is negative pressure, as long as open the pre-tightening tension that the power of intake valve can overcome valve spring, just can make intake valve open, and adopts Electromagnetic Drive intake valve, can guarantee that intake valve opens rapidly in good time, valve opening is large, and air inflow is sufficient, closes rapidly, when particularly high engine speeds turns round, power improves obviously; When compression and working stroke, inlet and outlet door is all in closed condition; When exhaust stroke, the pressure while being greater than intake stroke due to the pressure in cylinder, thus adopt actuated by cams, to make up the deficiency of using electromagnetic actuation force.
Do like this component that can reduce motor, rotating speed is promoted rapidly, power improves, and Energy Intensity Reduction, easily realizes modularization and the miniaturization of motor.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing is the structural representation of motor combination distribution device.

5: cam 6: rocking arm 7: exhaust valve spring 8: exhaust valve guide 9: exhaust valve
Embodiment
Below in conjunction with accompanying drawing, illustrate the composition and the working procedure that combine distribution device.This motor combination distribution device comprises by the gas handling system of Electromagnetic Drive with by cam-actuated vent systems.
Engine running starts, when the signal obtaining according to sensor in intake stroke Time Controller transmits electric power to intake valve electromagnetic coil module (1) as calculated, coil produces magnetic field, overcome the pre-tightening tension of inlet-valve spring (2), along intake valve conduit (3), promote intake valve (4) and open.Air inlet finishes, and intake valve (4) is closed rapidly under the effect of inlet-valve spring (2); When in compression stroke and working stroke, intake valve (4) exhaust valve (9) is all failure to actuate, under the effect of valve spring (2) (7) pre-tightening tension, in closed condition.When in exhaust stroke, exhaust valve (9) is under the rotation of cam (5), by rocking arm (6), overcome the pre-tightening tension of exhaust valve spring (7) and the pressure sum in cylinder, along exhaust valve guide (8), promoting exhaust valve (9) opens, exhaust stroke finishes, exhaust valve (9) cuts out under the effect of exhaust valve spring (7), completes a working stroke.
Claims (1)
1. a motor combination distribution device, is comprised of Electromagnetic Drive and actuated by cams, it is characterized in that: distribution device is by the gas handling system of Electromagnetic Drive and be comprised of cam-actuated vent systems.
