assembly, the negative pressure in the pressure chamber and by a mixed gas of intake air in the engine continues to increase under the action of, for: the set is greater than the elastic force of the spring force of the spring so that the diaphragm and the gas pressure on the diaphragm assembly in its own gravity and a gas pressure chamber and a mixed gas pressure of the negative pressure chamber and the downward force of gravity at the lower piston itself jointly generated by the piston exceeds the maximum elastic force of the spring, so that the diaphragm and the diaphragm piston assembly and the lower hole and the air before the gas input holes are not open to the input All kinematic compression spring mixed gas output opening hole, and with the engine intake air pressure so that the mixing chamber is atmospheric pressure and the negative pressure chamber at atmospheric pressure act on the diaphragm and the diaphragm assembly at an upward When the spring force is greater than the force of gravity and the lower diaphragm and the lower diaphragm and the piston assembly and the self-gravity of the downward force on the piston together, the lower diaphragm and the lower diaphragm assembly upward movement of the piston driven by compressed spring and synchronize open air input holes and gas input hole, then enter the amount of air from the air hole into the mixing zone, the gas from the gas pressure chamber through the gas passage hole by the gas input into the mixing zone and the mixing zone and air From the pilot jet and the mixed gas after the output aperture synthesis gas mixture has been mixed into the gas passage of the engine output, and with the air and gas mixture into the mixing zone so that the negative pressure decreases, and the pressure passage so that the mixed gas through the mixed gas followed by the negative pressure in the pressure chamber so that the mixed gas is reduced and the negative pressure in the pressure chamber and the atmospheric pressure chamber to atmospheric pressure under the joint action of the diaphragm in the upward force generated by the components and the lower diaphragm is followed by decrease and finally equal to its own spring under gravity and the force of the diaphragm and diaphragm assembly and the upper and lower pistons act on the gravity of the diaphragm and the lower diaphragm assembly under a downward force, so that the lower diaphragm and the diaphragm assembly and the lower piston stops moving, and the mixing zone of the negative pressure stable within a certain range, then the engine speed at the starting of its working mechanism is in an overload condition when the state of the engine and driving the control knob to open the gas valve to the maximum, thus: The gas The gas pressure reduction valve bore and the set of air input holes of the gas input to the ratio of engine overload dynamic air-fuel ratio of the gas mixture required at engine start and therefore the mixing of air and fuel gas into the mixing zone dynamic mixed gas concentration, when the engine speed drops in overload conditions in the unit time while reducing the intake air pressure is reduced resulting in a negative mixing zone and through the channel so that the negative pressure of the mixed gas mixture pressure chamber pressure also followed reduced, thus causing the diaphragm and the combined effect at lower diaphragm assembly is less than the upward force generated by the elastic force of the spring and the maximum under its own gravity and the diaphragm pressure chamber and the mixed gas under the negative pressure and the atmospheric pressure chamber to atmospheric pressure diaphragm assembly and the piston itself together in the downward force of gravity lower and lower diaphragm membrane components, this time under the lower diaphragm and the diaphragm downward movement of the piston assembly and release the spring and turn a small air synchronization input and gas input orifice hole, and because of the negative pressure of the air input hole and the gas input bore off small and the mixing zone have been restored by the pressure of the mixed gas passage such that the negative pressure of the mixed gas in the pressure chamber is restored, and so that the mixing air pressure and the negative pressure chamber to the atmospheric pressure chamber to atmospheric pressure under the upward force acting on the joint and the lower diaphragm of the diaphragm assembly is equal to its own gravity and the force of the spring and the lower diaphragm and the lower diaphragm assembly and the piston itself downward force of gravity acting on the lower joint and the lower diaphragm of the diaphragm assembly, the diaphragm and the lower case under the diaphragm assembly and the piston stops moving, while the engine speed is stabilized, while the engine is in an overload condition due to its speed mechanism driving the gas control knob input control valves fully open the gas valve and the gas pressure gas pressure chamber and gas channel is equal to the output of the gas pressure gas valve and the gas pressure makes the negative pressure chamber and the gas mixture pressure chamber Interaction downward force on the pressure on the diaphragm and the diaphragm piston assembly generates its own gravity and the lower and the upper diaphragm and the diaphragm assembly downward gravity force of the joint exceeds the maximum force of the spring, then the next the diaphragm and the lower diaphragm downward movement of the piston assembly and the lower compression spring to open the gas mixture output of all holes at the same time due to the ratio of the amount of the air inlet hole and the gas input holes is output based on the gas pressure in the gas valve is provided the ratio of the concentration of the mixture when the power of the engine when the overload condition as needed, so the orifice from the gas input into the gas mixing zone in the mixing region and the air and gas mixture for the synthesis of the mixed gas concentration dynamics, when the engine speed increases in unit time increases intake air at full load conditions, when the engine speed control mechanism driven off a small knob controls the opening of the gas valve and the gas pressure gas pressure chamber and gas channel is less than the gas valve gravity and gas pressure output, in which case the negative pressure chamber gas pressure gas pressure gas pressure chamber and mixed together in the diaphragm and the diaphragm assembly on the downward force and the diaphragm and the diaphragm assembly together under a downward force of the piston is equal to its own gravity and the force of the spring in a stationary state the maximum, while the piston is in the compression of the spring under the fully open aperture mixed gas output of the stationary state while the engine speed increases in intake air per unit of time increases the negative pressure makes the mixing zone followed by mixing air pressure increases and the channel so that the mixing chamber gas pressure increases the negative pressure also followed, and finally making the diaphragm and lower diaphragm assembly under its own gravity and the Gravity and the action of the spring on the piston itself together gravity and a downward force under the elastic force of the diaphragm in the diaphragm assembly and the lower pressure chamber of the gas mixture is less than the negative pressure and atmospheric pressure chamber at atmospheric pressure act on the diaphragm and the lower film plate assembly upward force, and the diaphragm so that the upper and lower diaphragm assembly lower piston driven to continue the upward movement of the compression spring to open the air inlet holes and the quantity of gas due to the air input until the input aperture hole and the gas input holes into the mixing zone continue to open negative pressure has been restored only to stop the movement, then the engine speed to get stability, while the engine speed to stop the drive input control valve gas control knob, while the gas pressure due to the gas chamber and the gas pressure inside the channel is less than gas reduction gas pressure valve output pressure, and thus the amount of input into the hole by the gas mixing zone of the gas flow be reduced, and the mixed gas and air mixing zone for synthesis of a compatible power and economy in a concentration in the mixed gas per unit time, when the When the engine light load, the engine speed is further increased, further increasing the engine intake air in the unit time, when the engine speed control valve mechanism driving the gas input control knob further off a small gas input control valve opening so that the gas pressure the gas chamber and the gas pressure inside the channel is less than the gas valve further output gas pressure, so the negative pressure chamber gas pressure gas pressure gas pressure chamber and mixed together in the diaphragm and the diaphragm assembly downward force and on the diaphragm and the diaphragm assembly piston itself under its own gravity and gravity act on the piston downward under the force less than the maximum elastic spring, the piston upward movement of the diaphragm and the release this end, driven diaphragm assembly the spring and the mixture off a small amount of the hole so that the engine output is restricted in the amount of intake air per unit time decreases, so that the engine rotational speed and finally restored to its original level, and means to stop the drive control of the engine speed adjustment knob, then the engine the intake air amount per unit time is reduced so that the negative pressure within the mixing zone is followed by reduced pressure and the air passage by mixing the mixed gas such that the negative pressure chamber pressure followed reduced, so that the mixed gas pressure of the negative pressure chamber and atmospheric pressure The atmospheric pressure chamber together under the upward force acting on the diaphragm and the diaphragm assembly is less than the lower diaphragm and the lower diaphragm assembly under its own weight and its own weight and the spring force of the combined effect of gravity and at the piston and the diaphragm downward force under the diaphragm assembly, thus releasing the downward movement of the piston diaphragm and the diaphragm spring assembly to promote and synchronize off a small amount of air input holes and gas holes until the negative input of the mixing zone due to the air pressure input off a small amount of gas input bore holes and have been restored and stop motion, then the engine speed to get stability, while when the gas pressure due to the gas pressure inside the chamber and the gas channel is less than the gas pressure regulator output further allows the gas input hole into the mixing zone of the gas flow is further reduced per unit of time, then the mixture of gas and air in the mixing zone of the concentration of economic synthesis mixture.
The invention has the beneficial effects as follows, the mixed gas that can supply with power character concentration in the time of motor overburdening operating mode make to start function to the greatest extent to greatest extent power stage, in the time of motor light load operating mode, can supply with the Economy that the mixed gas of Economy concentration uses combustion gas and utilized more fully.
