Abstract
An electronic ignition unit which can be installed as a simple replacement for a conventional distributor including a "breakerless" transector for supplying firing pulses in timed sequence to the spark plugs of a conventional internal combustion engine.
Claims4
An electronic ignition unit for an internal combustion engine having a drive shaft, spark plugs, an associated ignition coil and source of low voltage current which comprises
- a transector having adjacent but non-contacting rotor and stator, each with electrically-interacting cyclical-pattern conductors thereon,
- means for electronically connecting said transector stator conductor with the low voltage source,
- means for mechanically connecting said transector rotor with the engine drive shaft so as to produce a sequence of output pulses,
- a high voltage switch connected to receive the output pulses generated by said transector in response to rotation of said transector rotor, and adapted to generate a timed sequence of pulses for delivery to the ignition coil,
- means including an electronic latch and a latch-controlling differential amplifier for controlling the period of the pulse application to said high voltage switch, and
- a distributing switch electrically connected to said ignition coil for distribution of high voltage pulses in sequence to the engine spark plugs.
