Description
Technical field
A kind of Double-fuel guide rail fuel changing-over device is the utility model is related to, more particularly to a kind of automobile double spray-hole
Multiple-way valve.
Background technology
Turn with to vehicle economy and alternative fuel economy, the concern of the feature of environmental protection, automaker and Market for refitting
To more economical, Cleaning Equipment, to improve efficiency and energy-conserving and environment-protective, so alternative fuel or dual-purpose fuel or pluralities of fuel
Effectively use, it is necessary to the distinct configuration of traditional fuel engine associated components, wherein during for changing two kinds of fuel charges, it is necessary to
A kind of good switching device.General single track single spraying system of the prior art, led to before the spray rail and injector of former automobile
A set of methanol pipeline in parallel such as magnetic valve is crossed, in terms of simple in construction, repacking, but can not realize between gasoline-methanol and turn completely
Change, cause methanol cold start-up difficult.Chinese utility model patent application " automobile double spray-hole multiple-way valve 201510088541.9 "
Reliably switching, pipeline good airproof performance, valve core piston not drift, working stability can be realized between two kinds of motor vehicle fuels so that two kinds
Fuel such as methanol, gasoline, it is fed for engine while an injector and dependable performance can be shared.But lacked there is following
Fall into：First, because only that a valve pocket hole, ball valve core switching fuel luck every trade journey length, shake when causing igniting.In two kinds of combustions
Ball valve core can effectively reduce the heterodromous resistance of valve core piston during material switching, and this kind of fuel for promoting to be stopped feed passes through
Injector mounting hole fast evacuation, still, because ball valve core is curved surface, it is necessary between two end face cylinder plugs when switching fuel
Through hole section in do distant movement, such as, when shifting to gasoline from methanol, ball valve core from the left side move to the right, block the right side
The open trough of side end face cylinder plug, cuts off the supply of methanol, makes the gasoline in the built-in channel of the left side through flowing into the injection among through hole
Device mounting hole；When shifting to methanol from gasoline, ball valve core moves to the left side from the right, blocks the open trough of left side end face cylinder plug, cuts
Cut steam oil supply, make the right built-in channel in methanol flow into through hole among injector mounting hole.Because ball valve core not only but also
Play plugging action and ensure the through-flow of injector mounting hole again, so it moves left and right stroke farther out, so started in switching
When, it is difficult with methanol ignition start particularly in weather compared with cold season section, it is necessary to first with gasoline ignition start, in engine warms
Afterwards, can just switch to using methanol fuel, because ball spool stroke grow, cause the duration of ignition long and cause engine shake (because
For the duration of ignition for gasoline injection pulse width spray be residual methanol fuel) two be because between two end face cylinder plugs
Through hole section is long, and the original of the through hole section space is more using fuel quantity (methanol fuel is more), so during switching, (first
Alcohol ate) crude fuel amount residual quantity is more, and methanol fuel (crude fuel) force feed of residual is entered injector mounting hole by the movement of ball valve core,
There is more methanol fuel in injector mounting hole, influence igniting and start and (extend the duration of ignition and number).Third, ball valve core
Movement can only make valve pocket hole, the Fuel switching in fuel rail, and a large amount of crude fuels in spray-hole but left behind, and residual is excessive
The low fuel such as methanol fuel of flash-point can cause difficulty in starting, influence injector-ignition, it is necessary to be repeated several times igniting could point
Combustion.
The content of the invention
The purpose of this utility model, which is to provide between one kind can realize two kinds of motor vehicle fuels, reliably to be switched, two spray-holes and spray
Automobile double spray-hole multiple-way valve without crude fuel residual in emitter mounting hole, two valve core piston shift motions are short, and it switches fast, vapour
Car igniting non-jitter, working stability so that two kinds of fuel such as methanol, gasoline, an injector and dependable performance can be shared
It is fed for engine.
The utility model proposes one kind to include housing, injector mounting hole, and housing is provided with two valve pocket set up separately holes, each
