Batteryless starting and ignition system and method for internal combustion engine
First Claim
1. A batteryless starting and ignition system for a conventional automotive-type internal combustion engine adapted to drive an irrigation pumping station, said engine including an electrical system with an electric starter, alternator and voltage regulator, said system comprising:
- (a) battery replacement circuit which replaces and simulates the closed circuit effects of an automotive battery in said electrical system, said battery replacement circuit comprising a capacitor, a resistance element placed in series with said capacitor via a first diode of a first polarity, and a second diode placed in parallel with said resistance element and said first diode, said second diode having a polarity opposite from said first polarity;
(b) means for starting said engine via a removable external electrical power supply, said means for starting comprising a first jumper cable connector, said connector being placed in parallel across said battery replacement circuit, and a start switch for selectively connecting said first cable connector across the engine starter;
whereby(c) said engine will run continuously after said external power supply is removed.

Abstract
A batteryless starting and ignition system for a conventional automotive internal combustion engine includes a battery replacement circuit which simulates the effect of an operational automotive lead-acid battery in the engine electrical circuit while the engine is running. A jumper cable connector is wired across the replacement circuit to facilitate jump starting of the engine. The system is particularly useful to replace automotive batteries in irrigation systems in which automotive engines are adapted to drive irrigation pumps continuously for periods up to six months.
