ABSTRACT:
An expolsion chamber including a principle which allows a method of exploding various fuel vapors other than gasoline. High electrical energy input to the system is maximized as less combustible vapors are exploded.
The two unique features of the system are: 1. The timing is automatically set by standard ignition control which triggers the high energy exploding sequence. 2. Both the ignition injection and the high energy discharge are fed into the exploding chamber with the same electrode. This is possible through the utilization of a high voltage, high current diode stack. The stack is constructed, for example, of 288 diodes. The total peak inverse voltage (PIV) is about 24 kilovolts for ignition preservation and the current discharge surge is about 600 amperes. In the multiple chamber engine, one diode stack is required for each chamber. In the four chamber engine about 1,152 diodes are utilized. High power rheostats are placed in series with the stacks to control the dwell time of the electrical discharge.
