ABSTRACT:
A portable electrostatic liquid sprayer including a small internal combustion engine with a magneto-type ignition system providing a high voltage source to inductively charge atomized droplets being sprayed onto crops or plants. A conductive voltage tap is coupled between a spark plug boot from the magneto and the high voltage terminal of a spark plug for access to the high voltage provided by the magneto. A wire is connected to the voltage tap and routed and connected to an RC filter and rectifier circuit mounted in the sprayer head. A ground wire is electrically coupled to the chassis of the engine and also routed and connected to the RC filter and rectifier circuit. An electrode mounted near the outlet of the sprayer head and connected to the RC filter and rectifier circuit establishes an electrostatic field within the sprayer head effective to inductively charge the atomized droplets as they are being ejected from the sprayer head.
