Abstract
The invention discloses an electric control air valve driving mechanism for an automobile engine. The electric control air valve driving mechanism comprises components such as a high pressure oil supply pump [1], a common rail [2], an electric liquid executor [3], a rocker arm mechanism [4] and the like. By the mechanism, a throttling valve, a cam shaft and a starting machine of an engine can be eliminated; and the structure of the engine is simplified and the aims of saving energy and reducing emission of the engine can be fulfilled.
Description
Technical field
The present invention is a kind of automotive electronic control system valve actuating mechanism, can be according to the operating mode of motor, control the lift of the opening of valve, close moment and valve freely.
Background technique
Conventional engines is to utilize the control closure to change the air quantity that gets into cylinder, and decides fuel injection quantity through keeping watch on air mass flow.For this mechanism, driver's open out is exactly the aperture at the control closure in fact, thus the power of control motor.This control mode is owing to exist pumping loss, and energy loss is bigger.In addition, a lot of mechanisms are arranged now, though the port timing of motor is changed to some extent, its control degrees of freedom not enough, the port timing that can't accomplish freely to control motor.
Summary of the invention
The object of the invention just is to use the valve actuating mechanism of computer control to replace the valve actuating mechanism that is using; Simplify the structure of motor; Closure, camshaft and the starter motor of cancellation conventional engines; Eliminate the pumping loss of engine aspirating system, make motor reach purpose energy-conservation, that reduce discharging.In addition, owing to there has not been the obstruction of closure, fresh air gets into more smooth and easy, makes burning more abundant, and toxic emission still less.Change valve lift and switching time, can control the air quantity that sucks motor, power loss is remained on extremely low level.
The technical solution adopted for the present invention to solve the technical problems is:
This mechanism combines the content of diesel common rail technology, and soft rocking arm and the pitman arm shaft mechanism of orthodox car motor with electric control hydraulic pressure, with hydraulic control machinery, thereby reaches the purpose of controlling valve timing and lift.
Description of drawings
Fig. 1 is a plane structure chart of the present invention.
Among the figure: 1. high-pressure fuel-feed pump 2. is total to 3. electro-hydraulic actuator 4. rocker arm bodies of rail (high pressure accumulator)
The practical implementation method
With reference to Fig. 1, the control strategy of native system is with electric control liquid, with the plunger of hydraulic control system electro-hydraulic actuator.Control chamber links through a draining hole and a return tube by the high speed electromagnetic opening of valves.When the solenoid valve no electric circuit; The sealing of draining hole; When hydraulic coupling surpasses the elastic force summation of the hydraulic coupling that is applied on the pressure-bearing conical surface of electro-hydraulic actuator plunger bottom and return spring on valve control plunger; Plunger moves downward takes a seat; Move under rocking arm one side direction that is connected with the plunger bottom; And move engine throttled back at this moment on the other side direction of rocking arm.When ECU through each sensor of motor to engine operating condition when solenoid valve is triggered; Open in the draining hole; Pressure in the control chamber reduces; Hydraulic coupling on the plunger also reduces; In case when this hydraulic coupling eases down to the elastic force summation that is lower than the power that acts on the pressure-bearing conical surface of electro-hydraulic actuator plunger bottom and return spring, the electro-hydraulic actuator plunger just will move upward, and move on rocking arm one side direction that is connected with the plunger bottom; And move under the other side direction of rocking arm, engine valve just is opened.
Can know by above-mentioned working principle; The moment that engine valve is opened is controlled by the energising of high-speed electromagnetic valve constantly; The close moment of valve is by the power-cut time control of high-speed electromagnetic valve; The current"on"time length of the opening time of valve by solenoid valve decides; And dredge oil amount what the aperture size of high-speed electromagnetic valve determined, thereby controls the lift of valve indirectly.
Claims (1)
1. automotive electronic control system valve actuating mechanism, it comprises: a high-pressure fuel-feed pump [1]; The common rail (high pressure accumulator) [2] that each valve is shared; The rocker arm body [4] that adopts on electro-hydraulic actuator [3] and the conventional engines.
