Abstract

The present invention provides an ignition system for a pulse fog generator having a carburetor, a pump for pumping air into the carburetor, and a priming pump for directing a quantity of fuel into the carburetor. The ignition system includes an igniter operable on low voltage, a switch for activating and deactivating the igniter, and a grounding connection for grounding the igniter to the carburetor. The grounding connection includes structure for grounding the igniter including an igniter bracket and a ground wire assembly which couples to the igniter and to a location substantially near a sparkplug of the pulse fog generator.

Claims (16)

1. A method for igniting a pulse fog generator comprising a carburetor, a pump for pumping air into the carburetor, a priming pump for directing a quantity of fuel into the carburetor, and an ignition system including an igniter, the method comprising:

actuating a lever on the carburetor to an open position;

directing air and fuel to flow into the carburetor for combustion;

triggering a switch on the ignition system;

supplying a voltage of less than 12 volts DC to the igniter; and

igniting the pulse fog generator.

2. The method of claim 1 , further comprising supplying the less than 12 volts DC to the igniter at a frequency of between 10 to 20 Hz.

3. The method of claim 2 , wherein the step of supplying less than 12 volts DC comprises supplying 1.5 volts DC to the igniter.

4. The method of claim 2 , wherein the step of supplying less than 12 volts DC at 10 to 20 Hz to the igniter comprises supplying less than 12 volts DC at 10 Hz to the igniter.

5. The method of claim 1 , wherein the step of supplying less than 12 volts DC comprises supplying 1.5 volts DC to the igniter.

6. The method of claim 1 , further comprising grounding the igniter to the carburetor by a grounding connection.

7. The method of claim 6 , wherein the grounding connection comprises a plate for mounting the igniter to a chassis supporting the pulse fog generator.

8. The method of claim 7 , wherein the grounding connection further comprises a secondary ground wire assembly for grounding the igniter to a location substantially near a sparkplug of the pulse fog generator.

9. The method of claim 1 , wherein, as the lever is actuated to the open position, the lever is moved past a tipping point and a spring coupled between the lever and the carburetor biases the lever to the open position.

10. The method of claim 1 , further comprising moving the lever to a closed position to shut down the pulse fog generator.

11. The method of claim 10 , wherein, as the lever is moved to the closed position, the lever is moved past a tipping point and a spring coupled between the lever and the carburetor biases the lever to the closed position.
