ABSTRACT:
An ignition system having first and second modes of operation is part of an engine which develops motive power by burning fuel received in a main combustion chamber. An auxiliary combustion chamber that is integral with the main combustion chamber is provided. These chambers have a common passageway through which the auxiliary chamber receives a portion of the fuel. An electrical igniter is integral with the auxiliary chamber, the igniter having an electrically conductive base and an electrode insulated from such base. An ignition transformer is included that has a primary and secondary winding wherein the secondary winding is coupled to the electrode. A capacitorless excitation circuit is provided that is coupled to the primary winding for generating an electrical arc within the auxiliary chamber during the second mode of operation.
