Capacitor discharge ignition testing apparatus employing visual spark gap indicator
First Claim
1. A spark gap unit for an ignition testing apparatus providing on site testing of capacitor discharge ignition systems for internal combustion engines comprising a pair of spark gap electrodes mounted in spaced relation and having input power connection means, an enclosing housing enclosing the ends of the electrodes and the gap therebetween, said housing providing an essentially fluid tight enclosure, said housing including a small passageway means permitting a restricted fluid interchange between the inside and outside of the housing and restricting the propagation of a spark from between the electrodes outwardly of the housing while permitting the escape of gases from within the housing.

Abstract
Capacitor discharge ignition analyzer includes a pulse source operable to generate electrical signals related to the input-output signals of various capacitor discharge ignition systems including battery driven and alternator driven systems. The analyzer includes an electronic circuit generating an output signal approximating that of the permanent magnet alternators for charging of alternator driven systems and a circuit to generate a trigger pulse. The output of the capacitor is connected to a spark gap unit having an outer enclosure with a small opening. This permits direct testing of the ignition system on the engine without any practical danger of generating explosions as a result of surrounding gas fumes.
