Abstract
The utility model provides a multicylinder engine closes (air) intake valve control mechanism of shifter cylinder in jar economizer system, include the valve rocker and the (air) intake valve that correspond with the shifter cylinder, valve rocker's top sets up adjustment screw, and adjustment screw and decompression axle link to each other with the relative position that adjusts the two and by the lock nut locking through the screw thread, and adjustment screw passes through electromagnets dirver device pulling handle and anticlockwise rotation to spring messenger its rotate clockwise built -in through the electromagnets dirver device resets, and when the valve rocker swing makeed the (air) intake valve complete opening, adjustment screw held at the valve rocker valve that is in the minimum on rotatory just in time top. For compression work that reduces the inoperative jar and the purpose that economizes on fuel, when the valve rocker swing makeed the (air) intake valve complete opening, adjustment screw held at the valve rocker valve that is in the minimum on rotatory just in time top, realized that the (air) intake valve that is in the cylinder of closed condition is in open state.
Description
Technical field
The utility model relates to a kind of multicylinder engine cylinder closing oil-saving technical; Be specifically related to the intake valve control mechanism of shifter cylinder in a kind of multicylinder engine cylinder closing oil-saving system.
Background technique
Automobile, in order to obtain good power character, often has the larger margin of power in design.When vehicle urban district or descending road is up sail time, generally only need the 20%-40% of peak output, now engine load rate is lower, and fuel economy is poor, and the Harmful ingredient content simultaneously in toxic emission is higher.Adopt cylinder-variable Displacement Technology, namely closing some cylinders during sub load to improve engine load rate, is simple and method that is effective oil-saving discharging-reducing.
Cadillac early firmly just have employed cylinder-variable technology in 1980 first, and the vehicle of first this technology of equipment is that second generation Cadillac matches prestige, its v6 motor can close when not needing high-power output wherein two cylinders to save fuel oil.The popular 1.4 liters of TSI motors of motor winner in 2013, its maximum bright spot is automated variable displacement system.It carries out the conversion of two cylinders and four cylinder working patterns automatically at high and low different load, and hundred kilometers of comprehensive oil consumption only have 5.2L, every kilometer of discharge CO
2119g.
For the cylinder of closing, just control fuel oil and no longer spray in cylinder, intake valve and exhaust valve still realize regular keying under the effect of cam and push rod, and just there will be compression work increases, and oil consumption increases.
Summary of the invention
The technical problems to be solved in the utility model is to provide shifter cylinder intake valve control mechanism in a kind of multicylinder engine cylinder closing oil-saving system, can reduce engine compresses merit for the cylinder of closing.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
The intake valve control mechanism of shifter cylinder in a kind of multicylinder engine cylinder closing oil-saving system, comprise and the valve rocker corresponding to shifter cylinder and intake valve, the top of described valve rocker arranges adjustment screw rod, adjustment screw rod and decompression shaft to be connected by screw thread and by locking nut locking, adjustment screw rod pulls handle by electromagnet driving device and rotates counterclockwise, and make it rotate clockwise reset by the spring that electromagnet driving device is built-in, when valve rocker swing makes intake valve open completely, adjustment screw rod rotates and just in time withstands on the valve rocker valve end being in minimum point.
The intake valve control mechanism of shifter cylinder in above-mentioned multicylinder engine cylinder closing oil-saving system, adjustment screw rod is set above described valve rocker, when valve rocker swing makes intake valve open completely, adjustment bolt rotary makes it just in time withstand on the valve end of valve rocker.
During the to-and-fro motion of inoperative cylinder piston, pressurized gas is known from experience increases engine compresses merit, therefore, need to make the intake valve of the cylinder being in closed condition be in normally open, when valve rocker swing makes intake valve open completely, adjustment screw rod rotates and just in time withstands on the valve rocker valve end being in minimum point, and the intake valve realizing being in the cylinder of closed condition is in normally open.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described;
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram that intake valve is in opening state.
1. adjustment screw rod, 2. locking nut, 3. decompression shaft, 4. handle, 5. pull bar, 6. electromagnet driving devices in figure, 7. valve shakes stern, 8. intake valve.
Embodiment
As shown in Figure 2, the intake valve control mechanism of shifter cylinder in a kind of multicylinder engine cylinder closing oil-saving system, comprise and the valve rocker 7 corresponding to shifter cylinder and intake valve 8, the top of described valve rocker arranges adjustment screw rod 1, adjustment screw rod and decompression shaft 3 by screw thread be connected to adjust the two relative position and by locking nut 2 locking, adjustment screw rod pulls handle 4 by electromagnet driving device 6 and rotates counterclockwise, and make it rotate clockwise reset by the spring that electromagnet driving device is built-in, when valve rocker swing makes intake valve open completely, adjustment screw rod rotates and just in time withstands on the valve rocker valve end being in minimum point.Comprise and the valve rocker 1 corresponding to shifter cylinder and cylinder head 3, the top of described valve rocker arranges slide block 2, skid is supported in cylinder head lower face and can moves left and right along valve rocker length direction, the left end of slide block has downward projection, slide block pulls slide block to move right by electromagnet driving device 4 and makes slide block be moved to the left reset by the spring that electromagnet driving device is built-in, when valve rocker swing makes intake valve 6 open completely, slide block is moved to the left and makes its left end projection just in time withstand the valve rocker valve end being in minimum point.
Arrange adjustment screw rod above described valve rocker, when valve rocker swing makes intake valve open completely, adjustment bolt rotary makes it just in time withstand on the valve end of valve rocker.
