ABSTRACT:
An electronic ignition device for internal combustion engines is disclosed. The disclosed device employs a Hall sensor along with a Permanent Magnet (PM) mounted on a moving part of an engine to establish a reference point from which an Advance Firing Angle (AFA) is calculated and applied to the firing of a spark plug. The signal generated by the PM passing the active area of the Hall sensor is called the Master Reference Signal (MRS). The invention senses the speed of the engine and based on the speed of the engine sets an AFA for the firing of the spark plug from the set reference point. As the speed of the engine changes the AFA at the which the spark plug fires at is also changed by the invention. The invention also has a Regulated Supply Voltage Booster that boosts the supply voltage to a higher voltage for charging a capacitor that is used in capacitive discharge firing of a spark plug. This device also contains a means for the user of the invention to change the AFA of the firing of a spark plug while the invention and engine is running so that maximum performance of the engine may be obtained under different engine load conditions.
