ABSTRACT:
There is disclosed an electrical pulse generator for generating a train of high voltage pulses for spark ignition of multi-chamber, internal combustion engines operated at high speeds. The pulse generator comprises rotatable means mounted on the output shaft of the engine, typically on the dampener of the engine with cooperative pulse generating means carried on the engine housing adjacent the output shaft and responsive to the rotation thereof to generate the train of voltage pulses. In its preferred embodiment the pulse generating means comprises a coil winding which is mounted on a bracket secured to the engine with magnetic field generating means, such as a permanent magnet, to establish a magnetic circuit through the interior of the coil and magnetic flux means carried by the rotatable means mounted on the output shaft of the engine to generate a timed change in the magnetic flux of the magnetic circuit, thereby generating a train of induced voltage pulses in the coil windings. Typically, the magnetic flux means can comprise a plurality of machine bolts which are threaded into tapped bores about the periphery of the torsional dampener which is mounted on the engine crankshaft. The invention also comprises the combination of the aforedescribed pulse generator with the more conventional pulse generator usually contained within a conventional distributor for generating and distributing a train of high voltage pulses in an internal combustion engine.
