Abstract
The invention provides an inlet valve control mechanism of a shifter cylinder in a multi-cylinder engine cylinder deactivation oil saving system, which comprises a valve rocker arm and a cylinder cover which correspond to the shifter cylinder. A sliding block is arranged above the valve rocker arm; the sliding block is supported on the lower end face of the cylinder cover in a sliding mode and can slide left and right along the length direction of the valve rocker arm; the left end of the sliding block is provided with a downward bulge; the sliding block is pulled by an electromagnet driving device to move rightward and moves leftward to be reset by a spring arranged in the electromagnet driving device; and when the valve rocker arm swings to enable an inlet valve to be totally opened, the sliding block moves leftward, so that the bulge at the left end of the sliding block is just abutted against the valve end of the valve rocker arm, which is positioned at the lowermost point. For reducing the pumping loss of nonworking cylinders, when the valve rocker arm swings to enable the inlet valve to be totally opened, the sliding block moves leftward, so that the bulge at the left end of the sliding block is just abutted against the valve end of the valve rocker arm, which is positioned at the lowermost point, and thus, the effect that the inlet valve of the cylinder in a closed state is in a normally-open state is implemented.
Description
Technical field
The present invention relates to a kind of multicylinder engine cylinder deactivation fuel-saving technique, be specifically related to the intake valve control mechanism of shifter cylinder in a kind of multicylinder engine cylinder fuel-cut oil-saving system.
Background technique
Automobile-used multicylinder engine can bring more power reserve, meet run at high speed, heavily loaded goods, starting are anxious accelerates and the needs of climbing, but because discharge capacity nature can bring high oil consumption, for when heavily blocking zero load, or car is not when urban road stop-go needs strong impetus, the full cylinder working of multicylinder engine just seems and wastes very much.Therefore, closing some cylinders during sub load to improve engine load rate, is simple and effective fuel saving method.
Cadillac just have employed cylinder-variable technology first as far back as 1980, and the vehicle of first this technology of equipment is second generation Cadillac match prestige.Its V6 motor can close when not needing high-power output wherein two cylinders to save fuel oil.In 2006, the Buick Lacrosse 3.0 V6 Ultimate that Shanghai GM is issued was just with the DOD(Displacement On Demand that can close half cylinder) variable displacement system.Cherry in 2009 also have developed oneself DOD technology and by national acceptance, but does not also have volume production.
For the cylinder of closing, just control fuel oil not spraying in cylinder, intake valve and exhaust valve still realize regular keying under the effect of cam and push rod, just there will be pumping loss, consume a part of mechanical energy.
Summary of the invention
The technical problem to be solved in the present invention is to provide the intake valve control mechanism of shifter cylinder in a kind of multicylinder engine cylinder fuel-cut oil-saving system, for the cylinder of closing, greatly reduce pumping loss.
In order to solve the problems of the technologies described above, technological scheme of the present invention is:
The intake valve control mechanism of shifter cylinder in a kind of multicylinder engine cylinder fuel-cut oil-saving system, comprise and the valve rocker corresponding to shifter cylinder and cylinder head, the top of described valve rocker arranges slide block, skid is supported in cylinder head lower face and can horizontally slips 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 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 open completely, slide block moves right and makes its left end projection just in time withstand on the valve rocker valve end being in minimum point.
The intake valve control mechanism of shifter cylinder in above-mentioned multicylinder engine cylinder fuel-cut oil-saving system, the pad raised up is fixed with above described valve rocker valve end, when valve rocker swing makes intake valve open completely, slide block moves right and its left end projection is just in time withstood on pad.
In order to reduce to overcome in inoperative cylinder gas exchange process merit that Inlet drag consumes and overcome the merit that air outlet flue resistance consumes, i.e. pumping loss, the intake valve of the cylinder being in closed condition need be made to be in normally open, when valve rocker swing makes intake valve open completely, slide block moves right and makes its left end projection just in time withstand 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, the specific embodiment of the present invention is described in further detail:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the schematic diagram that intake valve is in opening state.
In figure: 1 valve rocker, 2 slide blocks, 3 cylinder head, 4 electromagnet driving devices, 5 pads, 6 intake valves.
Embodiment
As shown in Figure 1-2, the intake valve control mechanism of shifter cylinder in a kind of multicylinder engine cylinder fuel-cut oil-saving system, 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 horizontally slips 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 moves right and makes its left end projection just in time withstand on the valve rocker valve end being in minimum point.
Further, be fixed with the pad 5 raised up above described valve rocker valve end, when valve rocker swing makes intake valve open completely, slide block moves right and its left end projection is just in time withstood on pad.
Claims (1)
1. the intake valve control mechanism of shifter cylinder in a multicylinder engine cylinder fuel-cut oil-saving system, comprise and the valve rocker corresponding to shifter cylinder and cylinder head, it is characterized in that: the top of described valve rocker arranges slide block, skid is supported in cylinder head lower face and can horizontally slips 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 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 open completely, slide block moves right and makes its left end projection just in time withstand on the valve rocker valve end being in minimum point,
Be fixed with the pad raised up above described valve rocker valve end, when valve rocker swing makes intake valve open completely, slide block moves right and its left end projection is just in time withstood on pad.
