Abstract
An ignition system for a rotary piston engine uses the position of the rotary piston to generate the ignition timing pulse. A sensor is mounted in the wall of the epitrochoidal housing at a point opposite a rotor apex seal when the piston is at the maximum advance position. The timing signal is delayed by appropriate circuits and triggers high voltage generating circuits that provide igniting voltages to the trailing and leading ignition plugs at the proper time.
Claims10
An ignition system for an internal combustion engine having a housing and a rotary piston comprising,
- a. apex seals attached to the rotary piston and contacting the housing wall,
- b. a timing sensor attached to the housing, detecting the position of the seals and producing a timing signal output when the seal is in alignment with the sensor,
- c. variable delay means for electrically delaying the timing signal and producing a delayed timing signal output,
- d. high voltage generating means activated by the delayed timing signal and producing a high voltage signal,
- e. spark plugs positioned in the combustion chamber, connected to the generating means and producing ignition sparks when the high voltage signal is generated.
