An ignition system for an internal combustion engine having a transformer with a primary winding adapted to be connected to a power supply and a secondary winding adapted to be connected to a spark plug of the internal combustion engine, and a controller interconnected to the transformer so as to activate and deactivate the output of the transformer. The transformer serves to produce an output from the secondary winding having a frequency of between 1 KHz and 100 KHz and a voltage of at least 20 kilovolts. In particular, the transformer produces an output of an alternating current having a high voltage sine wave reaching at least 20 kilovolts. A voltage regulator is connected to the power supply and to the transformer so as to provide a constant DC voltage input to the transformer. The transformer produces power of constant wattage from the output of the secondary winding during the activation by the controller. A clamping circuit is connected to the secondary winding and to the spark plug so as to cause a peak-to-peak voltage from the secondary winding to fire the spark plug. The transformer is connected to the spark plug and to the controller so as to produce an arc of controllable duration across an electrode of the spark plug. This duration is selected from between 0.5 milliseconds and 4.0 milliseconds. A battery is the power supply which is connected to the primary winding of the transformer. This battery produces a variable voltage of between 5 and 15 volts.
