Description
Technical field:
The utility model relates to a kind of multi-jet double-fuel inlet manifolds of band.
Background technique:
Available engine mostly uses greatly fuel oil as fuel, predominantly petroleum, but with the shortage of petroleum resources, price
Expensive and science and technology progress, people increasingly pursue a kind of high-performance, low emission, low cost, high-environmental engine, thus
Dual fuel engine is produced, is also come into being with multi-jet double-fuel inlet manifold component.Double-fuel inlet manifold component
Applied to saving fuel oil on dual fuel engine, may be implemented to achieve the purpose that reduce cost, while also reaching higher
Discharge standard, meet national environmental protection policy.This dual fuel engine uses fuel gas (main component is hydrogen)+fuel oil to make
It for fuel, is done work by fuel combustion, is provided out power.
Available engine is general just to use gasoline or diesel oil as fuel, since gasoline, diesel oil are non-renewable resources, and
It is on the high side, improve people generally with vehicle cost.
Even if fuel engines emission control simultaneously is good again, also has a large amount of pollutants and be discharged into atmosphere, with China
Various vehicle fleet sizes increase, and pollution can aggravate, and destroy the environment that people depend on for existence.
Utility model content:
In order to overcome the above problem of the existing technology, it is multi-jet double that the purpose of the utility model is to provide a kind of bands
Fuel inlet manifold.
Above-mentioned purpose is realized by following technical scheme:
A kind of multi-jet double-fuel inlet manifold of band, composition includes: inlet manifold main body, the inlet manifold master
Body is connect with support frame, and fuel rail, hydrogen track are equipped on the support frame, and the end of the hydrogen track is set
It is equipped with gas rail air inlet, the end of the fuel rail is provided with oily rail oil inlet, has one group on the hydrogen track
Hydrogen air nozzle has one group of atomizer corresponding with hydrogen air nozzle, an atomizer and one on the fuel rail
A hydrogen air nozzle forms one group, provides two kinds of fuel for engine, and be the same cylinder for combustion gas and fuel oil.
The utility model has the beneficial effects that
The multi-jet double-fuel inlet manifold component of the utility model band can provide two kinds of fuel simultaneously for engine, and
According to the mixed proportion of two kinds of fuel of different Operating condition adjustments of engine, make up to power performance optimal under every kind of operating condition and
Discharge standard combines better economy, makes us with the engine of more oil-saving discharging-reducing low cost.The inlet manifold
Component mainly includes multiple atomizers and multiple air nozzles, corresponding fuel rail, hydrogen track and support frame, bolt fastener
Deng.It is different according to cylinder number, single cylinder engine and Multi-Cylinder Diesel Engine can be divided into, this scheme can be used.In the every of engine
One cylinder possesses an atomizer and an air nozzle respectively, and when engine operation, nozzle provides two kinds simultaneously for engine
Fuel, and it is different according to the operating condition of engine operation, by the mixed proportion of two kinds of fuel of electronic control unit adjust automatically, reach every
Optimal power performance and emission request under kind operating condition, so that operating cost be made to be greatly lowered.
The nozzle hole number of common atomizer and air nozzle is less, and about 4 ~ 6, injection diameter is larger.Compared with plain nozzle,
The utility model changes the diameter and quantity of fumarole and nozzle opening.The nozzle opening diameter specifications of the utility model are respectively
0.07mm and two kinds of 0.09mm (this numerical value can be adaptively adjusted according to the actual needs of different engines), is allowed to than just
The diameter of normal nozzle opening is small, changes simultaneously the quantity of nozzle opening, quantity is respectively totally four kinds of 16 holes, 18 holes, 26 holes, 30 holes at present
(this numerical value can be adaptively adjusted according to the actual needs of different engines) reaches improvement mixing by the above means
Gas dispersion effect and the purpose for adjusting jet amount and distributive value.By electronic control unit ECU according to the different operating conditions of engine,
Fuel injection time and spray volume are judged automatically and control, the spray volume being optimal keeps burning more abundant, improves engine
The thermal efficiency, the dynamic property and economy being optimal.
Detailed description of the invention:
Attached drawing 1 is the structural schematic diagram of the utility model.In figure, 1 is gas rail air inlet, and 2 be support frame, 3 for oily rail into
Hydraulic fluid port, 4 be atomizer, and 5 be fuel rail, and 6 be inlet manifold main body, and 7 be hydrogen track, and 8 be hydrogen air nozzle.
Specific embodiment:
Embodiment 1:
A kind of multi-jet double-fuel inlet manifold of band, composition includes: inlet manifold main body, the inlet manifold master
Body is connect with support frame, and fuel rail, hydrogen track are equipped on the support frame, according to the air inlet discrimination of different engines
Pipe is different, takes different support frame schemes to be used to support gas rail and oily rail, supporting way is more flexible, can be a support
Frame, is also possible to two support frames, and the end of the hydrogen track is provided with gas rail air inlet, the end of the fuel rail
Head is provided with oily rail oil inlet, has one group of hydrogen air nozzle on the hydrogen track, the gas componant of the hydrogen is main
For hydrogen, also includes other a small amount of gases, there is one group of atomizer corresponding with hydrogen air nozzle on the fuel rail,
One atomizer and a hydrogen air nozzle form one group, provide two kinds of fuel for engine, and be the same cylinder for combustion gas
And fuel oil.By improving intake manifold assembly structure, there are two types of nozzle systems for setting in assembly, are allowed to form an entirety,
It provides convenience to dismount and repairing.
The nozzle opening diameter specifications are respectively that (this numerical value can be according to different engines by 0.07mm and two kinds of 0.09mm
Actual needs be adaptively adjusted), be allowed to smaller than the diameter of normal nozzle opening, change simultaneously the quantity of nozzle opening, it is described
The quantity of nozzle opening be respectively 16 holes, 18 holes, 26 holes or 30 holes, (quantity of nozzle opening can be according to difference for totally four kinds of situations
