Description
Technical field
The present invention relates to a kind of Motor Vehicle manifold injection system guideways, particularly the split type guide rail of a kind of intake manifold.
Background technique
Along with the concern to vehicle economy and alternative fuel Economy, the feature of environmental protection, automaker and Market for refitting turn to more economically, Cleaning Equipment, to raise the efficiency and energy-conserving and environment-protective, so effective use of alternative fuel or dual-purpose fuel or pluralities of fuel, need the distinct configuration of traditional fuel engine components.
At present, existing air intake manifold of automotive engine guide rail mostly is integrated type guide rail, multiple discharge ports on guide rail are directly connected with the fuel inlet of the sparger be contained on each air inlet single tube, namely take hardwired mode, the guide rail of sizing can only support the use with the intake manifold of given shape and sparger.And for repacking or production double-fuel inlet manifold ejecting system, because the sparger quantity in intake manifold increases, the quantity also corresponding increase of guide rail, and integrated type guide rail volume is large, can not adjust flexibly again, often need by increasing intake manifold length, or increase flange or change the installation that the modes such as flange shape realize flange.This will cause following shortcoming: an interference causing other related accessory of automobile; The two effective conveyings affecting fuel fluid, can change and affect vehicle engine control system parameter.
Summary of the invention
The purpose of this utility model is to provide a kind of split type guide rail of intake manifold of compact, connected by flexible pipe between each split type guide rail, its angle, position can free adjusting, be convenient under the prerequisite such as shape and mounting point not changing original engine intake manifold and adpting flange, for supporting fuel rail loaded onto by the sparger increased, be vehicle motor conveying pluralities of fuel source as required.
The utility model proposes the split type guide rail of a kind of intake manifold, comprise the fuel pipe of two levels, coupling sleeve to lower open mouth, be provided with three through holes in it, coupling sleeve is sleeved on the upper end of sparger.
Preferably, described three through holes are T-shaped through hole, and coupling sleeve edge is provided with the positioning ring of an evagination.
The fuel pipe outer surface of described split type guide rail is provided with multiple conical surface bulge loop, and its cone point is towards the mouth of pipe of fuel pipe, and the cone end is towards coupling sleeve.
The fuel pipe outer surface of described split type guide rail is provided with cylndrical surface bulge loop.
The open-mouth end of described two fuel pipes is equipped with conical surface fillet.
Most these split type guide rails can in rows or in a row not be sleeved on multiple sparger, and the fuel pipe of adjacent two split type guide rails passes through soft pipe connection.
Described coupling sleeve is made up of the connecting cylinder of accumbency and upright mounting cylinder, and connecting cylinder bottom is plane, and mounting cylinder is connected on this plane.
Described positioning ring and a connection card match and split type guide rail are firmly connected with sparger, this connection card is the square body with three side elevations, top and side are uncovered, two relative side elevations have locating slot, bottom surface is the card of two band indent arc-shaped sides, one end of two cards is trapezoid-shaped openings, leaves spacing between the other end and medial side facade; When coupling sleeve cover is filled to sparger desired location, the indent arc checkpost of its two card enters in the draw-in groove of sparger, two locating slots of the positioning ring of coupling sleeve then Snap joint fastener.
The relative side elevation of described connection card two all slopes inwardly, and makes the spacing of the open-mouth end of two side elevations be less than the length of medial side facade.
The beneficial effects of the utility model are: the fuel pipe outer surface of split type guide rail is provided with multiple conical surface bulge loop, itself and have between flexible flexible pipe and seal, prevent from coming off simultaneously, or be provided with cylndrical surface bulge loop, also play the effect be tightly connected, install faster; The conical surface fillet of two fuel pipes, is convenient to import when flexible pipe is installed, makes installation faster; Connecting cylinder bottom is plane, makes it be connected with mounting cylinder more reliable, makes joint smooth, conveying gas uniform; This guide rail compact, occupy little space, connected by flexible pipe between each split type guide rail, its angle, position can free adjusting, be convenient under the prerequisite such as shape and mounting point not changing original engine intake manifold and adpting flange, for supporting fuel rail loaded onto by the sparger increased, also make sparger have adjustment leeway on position is selected, be embodied as vehicle motor conveying pluralities of fuel source; Positioning ring, connection card, sparger draw-in groove three coordinate, and realize sparger and are connected with the firm of split type guide rail, and connection is reliable, folding dress is convenient.
