When generator set used rock gas 12 to act as a fuel, when generator set is not worked, rock gas 12 pressure equated with the pressure of Wen's trunnion 8 throats, do not produce mobile.
When generator set uses rock gas 12 work, gasoline 11 is closed, air 13 launched machine piston movements suck multiple mixed gas and form device 15, when entering the throat of Wen's trunnion 8, produce flow at high speed gas, the throat pressure of Wen's trunnion 8 reduces, be sucked out at the second spout 9 place's rock gases 12, because the second spout 9 inclined-planes are airintake direction dorsad, direct steering flow direction, so that rock gas 12 is easy to enter mixed gas cavity 10 with air 13, advanced closure 7 and adjusted, enter the cylinder acting.Along with the variation of engine loading, closure 7 and engine speed are regulated automatically, and inflammable mixture is conversion thereupon, can guarantee effectively that the power of motor steadily exports.When the engine speed reduction of generator set and reducing of closure 7 opening sizes, mixed gas reduces gradually, until engine stop work, air 13 does not enter the throat of Wen's trunnion 8, rock gas 12 place's pressure equate with throat's place's pressure of Wen's trunnion 8, do not produce gas flow.
Can be found out by technique scheme, compared with prior art the utility model relates to and has following beneficial effect:
1. the rock gas suction tude is placed in the idling air jet side, does not have stopping of motor wind scooper, air filter and fuel tank, and the enough users of surrounding space remove and install gas hose;
2. only punch on former Petrol carburetter basis, technique is simple, and cost is low, is conducive to produce in enormous quantities;
3. increase the rock gas suction tude, this pipe particularity is that spout is processed into the oblique angle, during installation according to seam, with spout inclined-plane airintake direction dorsad, direct steering flow direction, and airflow stability had very large lifting, so that rock gas does not leak by throat fast;
4. be provided with through hole on the rock gas suction tude, guarantee that idling air jet connects, do not affect motor and use gasoline to act as a fuel;
5. the principle of structural design, technique are simple, can transform old money Petrol carburetter;
6. because the rock gas suction tude is reasonable in the throat position, and to the special processing of spout, so that when using rock gas to act as a fuel, engine output power is stable, has reduced gas consumption, reduce the pollution to environment.
Be to be understood that, although this specification is described according to mode of execution, but be not that each mode of execution only comprises an independently technological scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, technological scheme in each mode of execution also can through appropriate combination, form other mode of executions that it will be appreciated by those skilled in the art that.
