Description
Technical field
The present invention relates to a kind of motor vehicle manifold injection system, more particularly to the multi fuel of a kind of split type guide rail of band
Intake manifold injectors mounting device.
Background technology
With the concern to vehicle economy and alternative fuel economy, the feature of environmental protection, automaker and Market for refitting turn
To more economical, Cleaning Equipment, to improve efficiency and energy conservation and environmental protection, so alternative fuel or dual-purpose fuel or pluralities of fuel
It effectively uses, needs the distinct configuration of traditional fuel engine components.
Currently, existing air intake manifold of automotive engine is mostly one injector mounting hole of setting on each air inlet single tube,
It is only used for a kind of injection conveying of fuel.Repacking at present and production dual fuel injection system automobile primary will by increase flange and its
Its mode punches installation injector and guide rail, such as Chinese patent application " a kind of double fuel CN101131138 ", and increasing flange will
Increasing inlet manifold length has several big disadvantages：One causes the interference of the other related accessories of automobile；Two influence the effective of fuel fluid
Conveying, can change and influence vehicle engine control system parameter；Third, front-seat injector and injector holes generate oil film deposition
And covering；Fourth, the prior art mostly uses Contiuum type guide rail or integral type guide rail, multiple discharge ports on guide rail directly be mounted in
The fuel inlet of injector on each air inlet single tube is connected, that is, takes hardwired mode, the guide rail of sizing can only be with specific shape
The inlet manifold and injector of shape match.And for reequiping or producing double-fuel inlet manifold spraying system, because
Injector quantity in inlet manifold increases, and the quantity of guide rail also accordingly increases, and Contiuum type guide rail volume is big, and cannot be flexible
Adjustment is generally required through increase inlet manifold length, or is increased flange or changed the peace that the modes such as flange shape realize flange
Dress, repacking or production technology are complicated, of high cost；Fifth, for compact vehicle Contiuum type or integral type guide rail rear car market into
Row repacking is the interference that will produce to other accessories.
Invention content
The object of the present invention is to provide a kind of on inlet manifold increase injector quantity the split type guide rail of band more combustions
