Abstract
The utility model discloses a section-variable gas conduction tube, comprising a gas conduction tube provided with a bent part. The outer side wall of the bent part is a concave surface which is formed on the outer side wall of the bent part to reduce the space occupied by the outer side of the tube and is retracted towards the axis of the conduction tube. The radius of the deepest part of the concave surface is R1 which is less than R and not less than the half of the R, and the concave surface is naturally transited to a surrounding surface by being enlarged gradually from the deepest radius R1 to the surrounding radius. The middle part of the concave surface is a plane and is naturally transited with the surrounding surface; or the concave surface is a large-radius radian surface and is naturally transited with the surrounding surface. An included angle beta between a central axial surface A of the concave surface and a plane B wherein the bent conduction tube is arranged ranges from plus 90 degrees to minus 90 degrees. By the concave surface structure at the outer side wall of the bent part of the gas conduction tube, the safety distance between the gas conduction tube and a vehicle body can be enlarged, a gas flow line and layer flow are simpler to form, the air pressure drop is reduced, and the density of air entering into a combustion chamber of an engine is enlarged, so that the combustion efficiency of fuel oil is enhanced.
Description
Technical field
The utility model relates to a kind of variable cross section gas guiding tube, and particularly a kind of preventing need reduce the variable section structure that sectional area causes the motor car engine turbosupercharger gas handling system gas guiding tube of pressure-drop in pipeline increase because of dodging other component.Belong to motor car engine turbosupercharger gas handling system technical field.
Background technique
The motor that has the turbosupercharging gas handling system, need the high-pressure air of pressurized machine suction calmed the anger to hold from pressurized machine extrudes, and imports in the engine intake manifold via gas guiding tube and intercooler.The problem that the structure of existing gas guiding tube is moved towards to exist is for not enough with the safe distance of vehicle body; The method of dodging vehicle body through the variable cross section that reduces conduit radius or design general position can make air-pressure drop increase here; Get into the indoor air density of engine combustion thereby directly reduced, and then influenced the efficient of oil inflame.
Summary of the invention
The purpose of the utility model is to the problems referred to above a kind of safe distance that can satisfy vehicle body to be provided, and can reduce the variable cross section gas guiding tube of the motor car engine turbosupercharger gas handling system of air-pressure drop again.
The technological scheme of the utility model is such realization: it is concave face that the variable cross section gas guiding tube of the utility model is included in gas guiding tube crooked position outer side wall, and concave face is the concave face to the indentation of guiding tube axle center that outside the outer side wall formation of crooked position reduces, takes up room.
The described concave face innermost pipe radius that caves in is R1, and gas guiding tube radius is R, R＞R1 >=0.5R, and concave face progressively becomes pipe face nature transition big and normal place by the innermost pipe radius R 1 peripherad pipe radius of depression.
Described concave face middle part is the plane, with the pipe face nature transition at normal place on every side.
Described concave face is the major diameter arc shaped surface, with the pipe face nature transition at normal place on every side.
The angle β of the central axis plane A of described concave face and crooked conducting tubular axis place plane B is+90 °～-90 °, and preferred β is+60 °～-60, and further preferred β is+30 °～-30.
The advantage of the utility model: the utility model is through outer side wall is provided with the concave face structure in gas guiding tube bending part.Not only can increase the safe distance with vehicle body, and can make it more be prone to form gas streamline and laminar flow, reduce air-pressure drop, get into the indoor air density of engine combustion thereby increase, and then increased combustion efficiency of fuel oil.
