Description
Technical field
The present invention relates to gas automotive fuel dispensing device field, particularly relate to a kind of spray rail.
Background technique
The fuel that rock gas is used for vehicle motor not only can reduce Vehicular exhaust pollution greatly, and the utilization of above rock gas simultaneously is also that the existing vehicle population of alleviation increases fast, environmental aggravates and petroleum resources shortage present situation effective measures.Oil to gas is universal and popularization just worldwide, in China, also has many buses, taxi or even private car to take rock gas as fuel.
In fuel gas vehicle, electronic controlled gas injection system is requisite part, the quality of its service behaviour directly has influence on the utilization ratio of combustion gas and the output work of motor, in existing cylinder gas burning system, rock gas entered in spray rail after entering decompression, the output terminal of spray rail connects cylinder, the intermittent air feed of countercylinder.In prior art, spray rail for multi-cylinder generally arranges a gas inlet end, the output terminal that magnitude setting is equal with number of cylinders, but combustion gas when flowing in pipeline, because pressure in leading portion is greater than rear end, this just makes the output terminal delivery pressure near inlet end be greater than output terminal delivery pressure away from inlet end, causes the power distribution of each cylinder uneven, affect the uniformity that vehicle power exports in a short time, run will develop into the uneven wear of cylinder with this kind of operating mode for a long time.
Summary of the invention
When flowing in pipeline for above-mentioned existing combustion gas, because pressure in leading portion is greater than rear end, this just makes the output terminal delivery pressure near inlet end be greater than output terminal delivery pressure away from inlet end, cause the power distribution of each cylinder uneven, affect the uniformity that vehicle power exports in a short time, running the problem of the uneven wear by developing into cylinder for a long time with this kind of operating mode, the invention provides a kind of spray rail.
For solving the problem, one spray rail provided by the invention solves problem by following technological points: a kind of spray rail, comprise rail body, described rail body is provided with suction tude and multiple steam outlet pipe, described suction tude and steam outlet pipe all cut off spool by one and are connected, also comprise the control device that quantity is equal with cutting off spool quantity, described partition spool is separately fixed on a control device, described control device comprises iron, spring, connecting cylinder, screw column and coil, the two ends of described iron are connected with the partition end of spool and the end winding support of spring respectively, and iron and spring are all positioned at connecting cylinder, connecting cylinder connects in-orbit on body, screw column is threaded with connecting cylinder, and the free end of screw column one end and spring of going deep into connecting cylinder contacts, the axial direction of screw column is parallel with the axial direction of spring, coil is set on connecting cylinder,
Also be embedded with electric heating block in described rail body, in rail body, be also distributed with hot water flux.
Concrete, the partition spool arranged is used for controlling corresponding steam outlet pipe and the connected state of suction tude respectively, the control device arranged cuts off valve core movement to realize the switching of above-mentioned connected state for braking, in this structure, the magnetic fields produced after coil electricity forms electromagnet in iron, in non-energising situation, the bullet effect of stress of spring is on iron, cut off spool and be in blocking-up station, when after coil electricity, iron drives and cuts off the end motion of spool towards spring, and steam outlet pipe is communicated with suction tude follow-up gas cylinder air feed.In this structure, the screw column arranged is for adjusting the size of original state lower spring decrement, this sample spray rail is in dispatch from the factory debug phase or car maintaining, maintenance process, all be applied to the size adjustment spring of the power on corresponding spring to the size of the initial pressure stress of correspondence partition spool by adjusting each screw column respectively, like this, after coil electricity, be convenient to obtain different steam outlet pipes and the size being communicated with runner of suction tude for each steam outlet pipe, be convenient to like this obtain more balanced steam outlet pipe air feed.As for the steam outlet pipe near suction tude, by the pressure stress between the screw column on corresponding control device and spring is regulated larger, be convenient to like this obtain less communication passage sectional area.
Significantly step-down is needed because rock gas enters into cylinder by gas cylinder, decompression is originally as endothermic process simultaneously, for promoting the rate of combustion of combustion gas and the stability of burning, electric heating block and hot water flux are set in body in-orbit for heating the combustion gas flowing through steam outlet pipe, like this, after combustion gas can be made to enter into cylinder, there is better disperse effect, well mix and smooth combustion in the cylinder with combustion-supporting gas, be beneficial to the stability of engine operation.In the present invention, adopt the vibrational power flow that electric heating block and hot water flux are set simultaneously, electric heating block can be thermal resistor, hot water flux is for introducing engine cooling water, when above structure is intended to just start for vehicle, particularly in the environment of cold, can the electric energy of storage battery be utilized to heat the combustion gas flowing through steam outlet pipe by electric heating block in advance, rising to a certain degree until the cooling water temperature in hot water flux switches to water to heat with energy saving again, like this, can make to spray rail can provide good combustion gas to export at short notice, turn round and look at the present invention and also help the shortening heat car time.
