Description
Affiliated technical field
The utility model relates to a kind of nozzle that is applicable to the combustion gas vehicle, refers to a kind of car engine nozzle before of being located at especially.
Background technique
Generally use gasoline and the liquid gas vehicle as fuel simultaneously, its gas supply system provides liquid fuel by the gas steel cylinder as shown in Figure 4, is gaseous state via filter to vaporizer, is delivered to the engine internal combustion via nozzle again; Other establishes an Electronic Control Unit, and it is at ordinary times except the running of Control Engine, and when desiring to use gasoline instead and be fuel, i.e. control is switched, and by control computer control shut-off nozzle, and changes by oil-fired system.
And general vehicle is that with the difference of gas nozzle and fuel nozzle the unit time flow of gas nozzle is much larger than fuel nozzle.Therefore, in order to make gas nozzle that enough combustion gas are provided, way commonly used at present is to prolong discharge time, but thing followed result is an engine when being in high-revolving situation, this system will be continuous injection system but not sequencial jet system, to such an extent as to the unburnt situation of combustion gas is quite serious, cause the air consumption of vehicle and soiling value to improve.It is to strengthen the bore of gas nozzle mouth that another kind is done rule, yet, only be that increasing gas nozzle bore is not a solution, because gas nozzle is to open by the shutter that a solenoid valve drawing one is positioned at the nozzle case, make combustion gas pass through that shutter sprays again, after strengthening the gas nozzle mouth, the pressure of combustion gas will make the shutter of heavy caliber gas nozzle open, to such an extent as to need to strengthen the volume and the drawing gravitation of solenoid valve, shutter could be opened, but promptly can increase expense thus, and general engine chamber there is not so big containing space to place yet.
Summary of the invention
In order to improve the defective of above-mentioned existing vehicle with gas nozzle, main purpose of the present utility model is to provide a kind of bore that only strengthens gas nozzle, but does not increase under the solenoid valve volume, can improve the designs of nozzles of the output flow of combustion gas.
Based on above-mentioned purpose, the major technique means that the utility model adopts are to provide a kind of nozzle that is applicable to the combustion gas vehicle, its nozzle case by a hollow, be assembled in solenoid valve in the nozzle case, by the shutter of solenoid-driven displacement, be assembled in the outer main body of shutter, the spring that stays between shutter and the solenoid valve is formed, wherein, the nozzle case is to assemble by a piston outer cover and base institute is involutory, the piston outer cover relative with base away from two ends be respectively equipped with the suction port and the air outlet of combustion gas;
Be assembled between electromagnetic coil and the piston outer cover inwall in the piston outer cover of nozzle case and have the gap, this gap communicates with the suction port of piston outer cover, and other is assembled with a fixed piston in electromagnetic coil towards an end of suction port;
Described main body is assembled in the base of nozzle case, and keep the gap with the base inner circle wall, the inside of main body is provided with a combustion gas circulation chamber, the opening end of this combustion gas circulation chamber is towards the piston outer cover, and the inner edge stage casing of combustion gas circulation chamber radially is equipped with and is kept off edge on one, contiguous closed end then is provided with and keeps off edge, the internal diameter of this time retaining edge is less than last retaining edge, other is provided with at least one following air inlet that radially runs through following retaining edge perisporium and wears groove, and at least one being located on down kept off edge and axially run through to play giving vent to anger of edge of retaining to wear groove, this is given vent to anger and wears groove and be connected with the air outlet of base, then radially runs through at least one and go up air inlet and wear groove on the perisporium between last retaining edge and the body openings end;
Described shutter has a piston rod that penetrates in the middle of the electromagnetic coil, on an end of the contiguous main body of this piston rod, be interval with dish type last slice and sheet down, upper and lower is closed in going up the retaining edge, keeping off edge down of main body respectively;
Described spring is to stay between the piston rod and fixed piston of shutter.
Enter when combustion gas after the nozzle case inside of nozzle, will by the last air inlet of main body wear groove and following air inlet wear groove branch to last slice top of shutter, down below the sheet, make the upper and lower sides pressure of shutter keep balance, so what the electromagnetic coil energising was produced is excitatory as long as the elastic force of spring is fallen in payment, promptly the shutter drawing can be left, make and the gas of the last slice top be positioned at shutter to flow out apace via the inside of main body, the air outlet of base.
That is to say, the beneficial effects of the utility model are, even under the gas flow of bore with the raising unit time of fuel air mouth that adds giant and air outlet, shutter still only is subjected to the elastic force of spring and shores, as long as therefore the excitatory elastic force that can offset spring of electromagnetic coil generation can make combustion gas flow out so that shutter moves, so the volume of electromagnetic coil and whole nozzle does not need to increase, with cost saving and shared space.
In addition, because design of the present utility model can be strengthened the flow velocity and the flow of combustion gas, the ample supply engine combustion is required, that is to say that engine does not need continuous injection, and still can adopt sequence-injection, therefore reduced the air consumption and the incomplete atmospheric pollution that produces of fuel gas buring of vehicle.
