Abstract
The utility model provides an air inlet valve control mechanism of a closing cylinder in a multi-cylinder engine cylinder-stopping oil-saving system. The air inlet valve control mechanism comprises an air valve rocking arm and a cylinder cover which correspond to the closing cylinder. A sliding block is arranged above the air valve rocking 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 of the air valve rocking arm. The left end of the sliding block is provided with a downward protrusion. An electromagnet drive device drives the sliding block to move right and a spring arranged in the electromagnet drive device drives the sliding block to move left to reset. When the air valve rocking arm swings to enable the air valve to be completely started, the sliding block moves left so that the protrusion at the left end of the sliding block can right abut against an air valve end of the air valve rocking arm of the lowest point. To reduce loss of a non-working pump, when the air valve rocking arm swings to enable the air valve to be completely started, the sliding block slides to the left and enables the protrusion at the left end of the sliding block to right abut against the air valve end of the air valve rocking arm of the lowest point, so normal opening state of the closed air inlet valve of the cylinder is achieved.
Description
Technical field
The utility model relates to a kind of multicylinder engine cylinder deactivation fuel-saving technique, the concrete intake valve control mechanism that relates to shifter cylinder in a kind of multicylinder engine cylinder deactivation economizer system.
Background technique
Automobile-used multicylinder engine can bring more power reserve; Satisfy run at high speed, heavily loaded goods, starting are anxious quickens and the needs of climbing; But because discharge capacity nature can bring high oil consumption; When heavily card is unloaded, perhaps car when the urban road stop-go does not need strong impetus, the very waste that just seems of the full cylinder working of multicylinder engine.Therefore, closing some cylinders during sub load to improve engine load rate, is simple and effective fuel saving method.
Cadillac has just adopted the cylinder-variable technology first as far back as 1980, first this technological vehicle of equipment is second generation Cadillac match prestige.Its V6 motor can cut out wherein two cylinders to save fuel oil when not needing high-power output.In 2006, the Buick Lacrosse 3.0 V6 Ultimates of Shanghai GM issue just had DOD (Displacement On Demand) the variable displacement system that can close half cylinder.Cherry had also developed own DOD technology also through national acceptance in 2009, but did not also have volume production.
For the cylinder of closing, just control fuel oil not in spraying into cylinder, intake valve and exhaust valve are still realized clocklike opening and closing under the effect of cam and push rod, pumping loss will occur, consume a part of mechanical energy.
Summary of the invention
The technical problem that the utility model will solve provides the intake valve control mechanism of shifter cylinder in a kind of multicylinder engine cylinder deactivation economizer system, for the cylinder of closing, reduces pumping loss greatly.
In order to solve the problems of the technologies described above, the technological scheme of the utility model is:
The intake valve control mechanism of shifter cylinder in a kind of multicylinder engine cylinder deactivation economizer system; Comprise and pairing valve rocker of shifter cylinder and cylinder head; The top of said valve rocker is provided with slide block; The slide block sliding support also can horizontally slip along the valve rocker length direction in cylinder head lower face, and the left end of slide block has downward convexity, and slide block moves right and through the built-in spring of solenoid actuated device slide block is moved to the left through solenoid actuated device pulling slide block and resets; When valve rocker swing made the intake valve complete opening, slide block was moved to the left the valve rocker valve end that makes its left end convexity just in time withstand on to be in minimum point.
The intake valve control mechanism of shifter cylinder in the above-mentioned multicylinder engine cylinder deactivation economizer system; Said valve rocker valve end upper fixed has the pad that raises up; When the valve rocker swing made the intake valve complete opening, slide block was moved to the left and makes its left end convexity just in time withstand on the pad.
In order to reduce to overcome in the inoperative cylinder gas exchange process merit that the intake duct resistance consumed and to overcome the merit that the air outlet flue resistance is consumed; It is pumping loss; Need the feasible intake valve that is in the cylinder of closed condition to be in normally open; When valve rocker swing made the intake valve complete opening, slide block was moved to the left the valve rocker valve end that makes its left end convexity just in time withstand on to be in minimum point, and the intake valve of realizing being in the cylinder of closed condition is in normally open.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is in the schematic representation of opening state for intake valve.
Among the figure: 1 valve rocker, 2 slide blocks, 3 cylinder head, 4 solenoid actuated devices, 5 pads, 6 intake valves.
Embodiment
Shown in Fig. 1-2; The intake valve control mechanism of shifter cylinder in a kind of multicylinder engine cylinder deactivation economizer system; Comprise and pairing valve rocker 1 of shifter cylinder and cylinder head 3; The top of said valve rocker is provided with slide block 2; The slide block sliding support also can horizontally slip along the valve rocker length direction in cylinder head lower face, and the left end of slide block has downward convexity, and slide block moves right and through the built-in spring of solenoid actuated device slide block is moved to the left through solenoid actuated device 4 pulling slide blocks and resets; When valve rocker swing made intake valve 6 complete openings, slide block was moved to the left the valve rocker valve end that makes its left end convexity just in time withstand on to be in minimum point.
Further, said valve rocker valve end upper fixed has the pad 5 that raises up, and when the valve rocker swing made the intake valve complete opening, slide block was moved to the left and makes its left end convexity just in time withstand on the pad.
