Abstract
The utility model relates to a directly spout vortex top land combustion chamber belongs to automobile engine's technical field. The utility model discloses a directly spout vortex top land combustion chamber, including spark plug, sprayer, exhaust passage, intake duct and piston, the top land is dodged hole and (air) intake valve by the heart -shaped pit of piston top protruding, piston, exhaust valve and is dodged the hole and constitute. The combustion chamber during operation forms air mixture with sprayer spun high pressure fuel from intake duct effluent air behind the entering cylinder to light by the spark plug and guaranteed abundant burning through the guide production of heart -shaped pit both sides wall along two strands of vortex of circumference moving. The utility model discloses a directly spout vortex top land combustion chamber is reduce heat loss and flow losses effectively, improve explosion pressure, have not only improved combustion efficiency, and then improve the dynamic property of engine, have also reduced the exhaust emissions simultaneously.
Description
Technical field
This utility model is related to the technical field of automobile engine, and more specifically, this utility model is related to a kind of direct-injection
Vortex top land combustor.
Background technology
Put direct-injection gasoline engine piston top combustion chamber in the prior art and mostly be circular or oval-shaped groove design, burning is slow
Slowly, flame propagation velocity is low, and efficiency of combustion is low, and oil consumption is high, and in waste gas, CO and CH discharge capacity is big；Many with the air intake duct of piston cooperation
For straight air flue, the vertical tumble flow of single consideration and charge flow rate coefficient, do not strengthen venturi effect design, before being unfavorable for that gaseous mixture is lighted
The formation of tubulence energy.
Utility model content
In order to solve above-mentioned technical problem of the prior art, the purpose of this utility model is to provide a kind of direct-injection vortex
Top land combustor.
In order to realize above-mentioned utility model purpose, this utility model employs technical scheme below：
A kind of direct-injection is vortexed top land combustor, including spark plug, fuel injector, exhaust duct, air intake duct and piston；It is special
Levy and be：Described top land is by top land projection, piston heart pit, exhaust valve avoids hole and inlet valve avoids hole group
Become.
Wherein, from air intake duct effluent air, the high pressure fuel spraying with fuel injector after entering cylinder during combustion chamber operational
Form air mixture, and produced the two bursts of vortex circumferentially operating by the guiding that spark ignitor passes through heart-shaped pit two side walls
Ensure that abundant burning.
Wherein, described spark plug is arranged on exhaust duct side, and described fuel injector is arranged on air intake duct side.Further
Ground, has the angle of inclination between the axis of the axis of described fuel injector and described air intake duct.
Compared with prior art, direct-injection vortex top land combustor described in the utility model has following beneficial effect
Really：
Direct-injection vortex top land combustor of the present utility model can effectively reduce heat loss and flow losses, improves quick-fried
Send out pressure, not only increase efficiency of combustion, and then the dynamic property of raising electromotor, also reduce exhaust emissions simultaneously.
Brief description
Fig. 1 is the overall structure diagram of the direct-injection vortex top land combustor of embodiment 1.
Fig. 2 is the schematic diagram of top land.
Fig. 3 is the schematic cross-section in Fig. 2 along A-A direction.

Specific embodiment
Below with reference to specific embodiment, direct-injection described in the utility model vortex top land combustor is done further
Elaboration, to help those skilled in the art that utility model of the present utility model is conceived, technical scheme have more complete, accurately
With deep understanding.
Embodiment 1
As Figure 2-3, the direct-injection vortex top land combustor of the present embodiment, including spark plug 1, fuel injector 2, aerofluxuss
Road 3, air intake duct 5 and piston 4.Described spark plug 1 is arranged on exhaust duct 3 side, and described fuel injector 2 is arranged on air intake duct 5 side.
Further, there is between the axis of described fuel injector 2 and the axis of described air intake duct 5 angle of inclination.Described piston top
Portion is by top land projection 6, piston heart pit 7, exhaust valve avoids hole 8 and inlet valve avoids hole 9 and forms.During combustion chamber operational
From air intake duct effluent air, the high pressure fuel spraying with fuel injector after entering cylinder forms air mixture, and by spark plug point
Combustion produces, by the guiding of heart-shaped pit two side walls, the two bursts of vortex circumferentially operating and ensure that abundant burning.The present embodiment
Top land Combustion chamber design is become heart-shaped bowl configurations by chamber structure, from air intake duct effluent air, after entering cylinder,
The high pressure fuel spraying with fuel injector forms air mixture, as shown in figure 4, producing edge by the guiding of heart-shaped pit two side walls
Two strands of vortex gas flow of circumference operating, axially have the tumble flow air-flow of operating simultaneously, so can make to obtain in cylinder simultaneously along cylinder
Suitable vortex and Tumble intensity, make combustion gas mixing more fully and rapid, be conducive to gaseous mixture uniform, burn completely, carry
High burning efficiency, reduces exhaust emissions simultaneously；Reduce heat loss and the flow losses of combustor, lift explosion pressure, and
By putting fuel injector and spark plug in reasonable Arrangement, spark plug is placed in exhaust side, and fuel injector is placed in air inlet side, and have
Certain inclination angle, maximally utilizes intake swirl effect, improves engine fuel efficiency of combustion, improves the dynamic property of electromotor
Can, decrease exhaust emissions.Compared with conventional circle or oblong pits (two bursts of vortex can not be formed), generally can improve
Efficiency of combustion 5～10%.
For the ordinary skill in the art, specific embodiment has simply carried out exemplary retouching to this utility model
State it is clear that this utility model implements simultaneously, or not improved by of the present utility model design and technical scheme directly apply to
Other occasions, all within protection domain of the present utility model.Do not limited by aforesaid way, as long as it is new to employ this practicality
The improvement of the various unsubstantialities that the method design of type is carried out with technical scheme.
