Summary of the invention
Shortcomings such as the utility model is at producing eddy current easily when air-flow enters cylinder in the prior art, air-flow velocity is too low, and air inflow is low provide the charge air flow flow velocity high air passage structure.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Height rolls the gas road, comprise air flue that is provided with in the motor and the cylinder that communicates with air flue by valve, air flue is the circular cross-section passage, and the aditus laryngis place of air flue links to each other with valve, valve communicates with cylinder, and the internal diameter of aditus laryngis and valve connecting place is less than the internal diameter of air flue suction port.
The air that engine combustion uses is transported in the cylinder by air flue, at cylinder and air flue joint valve is arranged, valve is used to control the opening and closing of air flue, constantly adjust valve control air inlet along with the progress of engine stroke, directly make air enter the phenomenon that the reverse refunds of a part of gas then appears in cylinder easily from air flue, have influence on the air inlet effect, aditus laryngis place internal diameter is turned down has then increased air-flow velocity, also is more prone to promote to roll stream.
As preferably, the suction port of air flue remains unchanged to one section that links to each other with aditus laryngis internal diameter.
The suction port of air flue, enters the aditus laryngis place and plays internal diameter and diminish and then increase air-flow velocity easily in order to guarantee that air-flow enters more fully until the internal diameter at aditus laryngis place remains unchanged, and strengthens cylinder interior gas and rolls the stream effect.
As preferably, aditus laryngis forms downward-sloping along the cylinder direction.
There is bigger downward radian in the air flue stage casing, and aditus laryngis goes out to form convergent, and the aditus laryngis place forms wedge angle, and wedge angle is to be processed in air flue profile bottom by the control cutter, forms wedge angle with air flue casting inwall.This wedge angle can produce flow separation, can avoid the air flows downward behind the intake valve like this, and exhaust side departs from cylinder, also can increase in-cylinder tumble flow accordingly.
