Technical field
The utility model relates to the motor of vehicle, is specifically related to a kind of highly roll gas road and motor.
Background technique
Along with the requirement of market to vehicle economy and power character improves constantly, motor trend miniaturization directly spray, to reduce oil consumption, is applied various supercharging technology simultaneously and is ensured power character, cause engine load significantly to increase.For petrol engine, the increase of load means that tendency to detonate more seriously, is generally taken a breath by quickening burning, optimization, is strengthened the means reduction tendency to detonates such as cooling.In addition, in-cylinder direct injection brings the problems such as air-fuel mixture uniformity, oil dilution.
Height rolls gas road, is in engine operation process, to form the intake duct of tumble motion in cylinder.Height rolls the tumble motion that gas road produces can keep the kinetic energy of air-flow in cylinder, rolls stream broken by piston compression in igniting budc, is converted into small scale turbulence, improve tubulence energy in time of ignition cylinder, accelerate flame propagation, accelerate combustion process, suppress tendency to detonate, improve the thermal efficiency; Tumble motion improves the air-fuel mixture of direct fuel-injection engine simultaneously, reduces pollutant emission.So it is the key technology realizing engine performance that height rolls gas road.Common height rolls gas road as shown in Figure 3, existing height rolls the top that gas road 10 is arranged on firing chamber 5, firing chamber 5 is positioned at the top of cylinder 6, rolls stream and refers to when through the momentum gap of the upper and lower two strands of air-flows in intake valve 2 place is larger, form the air motion of rotation in cylinder.Existing height rolls gas road 10 when guaranteed flow coefficient, and Tumble intensity is lower, effectively can not accelerate burning, improve air-fuel mixture.
For solving the problem, Chinese patent CN101660471B has announced a kind of petrol engine air inlet, it is the high-order tangential inlet duct of integrated type two intake valve, firing chamber with matching is pitched roof formula firing chamber, the valve guide bushing boss of intake duct is provided with in the outside of intake duct body, the angle γ of the two curved surface tangential direction that described intake duct body is adjacent with air flue aditus laryngis position is between 60 ° ~ 150 °, the air inlet passage center line of intake duct body and intake valve centerlines β are between 30 ° ~ 60 °, the air inlet passage center line of described intake duct body and exhaust combustion chamber side plane angle α are between 10 ° ~ 15 °.Adopt said structure that this petrol engine air inlet can be made to have higher Tumble intensity and flow coefficient, and realize taking into account of petrol engine air admission road Tumble intensity and flow coefficient.But when engine load increases further, the Tumble intensity of this intake duct does not still reach requirement, in order to effectively accelerate burning, improving air-fuel mixture, needing the Tumble intensity strengthening intake duct further.Simultaneously, market also existing by installing the technology that automatically controlled valve block realizes Variable tumble intensity in inlet mouth or intake duct, to accelerate burning, improving air-fuel mixture, but there is the problems such as cost is high, control is complicated, product development cycle is long in this technology, wouldn't be suitable for large-scale application.
Summary of the invention
Propose during the purpose of this utility model a kind of highly to roll gas road and motor, this height roll stream air passage structure simple, be easy to realize, Tumble intensity can be increased further on the basis of existing technology.
One described in the utility model is high rolls gas road, comprise air flue, one end of described air flue is entrance, the other end of described air flue is outlet, described outlet is used for being connected with inlet valve seat ring, inlet valve seat ring is used for coordinating with intake valve the connected sum realized between air flue and firing chamber and cuts off, the inwall of described air flue near one end of described outlet is provided with protruding first surface and the second curved surface of depression, described first surface and the second curved surface are oppositely arranged centered by the center line of described air flue, the exhaust side of described first surface and described firing chamber is adjacent, described first surface is roughly parallel to the roof of described exhaust side near the side of described outlet, described second curved surface flows towards the exhaust side of described firing chamber for guiding the air-flow in described air flue, to strengthen Tumble intensity.
Adopt technique scheme, first surface is set, and first surface is roughly parallel to the roof of the exhaust side of described firing chamber near the side of described outlet, to reduce the flow resistance of air-flow at the outlet port of air flue and inlet valve seat ring place and disturbance, the roof of the exhaust side of firing chamber of fitting with making airflow smooth enters cylinder; Second curved surface being set, flowing, to increase Tumble intensity towards the exhaust side of described firing chamber for guiding the air-flow in described air flue.
Further, the inwall of described air flue is provided with protruding corner angle, and described corner angle are between described outlet and described second curved surface.Adopt said structure, air-flow is forming flow separation through corner angle, and enhanced flow, to the air-flow of the exhaust side of firing chamber, weakens the air-flow of the air inlet side flowing to firing chamber, increases Tumble intensity further.
Further, between the inwall of described first surface and described air flue, adopt smooth transition, between described second curved surface and the inwall of described air flue, adopt smooth transition.Adopt said structure, airway cross-section shape is not suddenlyd change, and ensures that the flowing of air-flow in air flue is smooth and easy.
The invention also discloses a kind of motor, comprise above-mentioned height and roll gas road.
The utility model significantly can increase Tumble intensity, and then accelerates burning, improves air-fuel mixture, improves engine power performance and Economy, reduces pollutant emission.
