Built-in electronic igniter

The utility model belongs to an electronic ignition device used by matching with an engine of a gasoline motor car, which adopts a signal wheel which is installed on an original cam and a shell seat fixed on a bottom board of a breaker, wherein, a magnetic pole used for generating magnetic induction signal is arranged on the signal wheel, a Hall element and a circuit device are arranged in the shell seat, and the magnetic signal is changed into an electric signal pulse which is exported through circuit treatment to generate ignition voltage. The utility model has the advantages that structure is simple, encapsulation is one-piece in the shell seat, and external connection adopts single wire; the utility model is suitable for universal installation. The utility model solves the existing puzzle in the process of popularization for an electronic ignition machine, can be used by matching with various gasoline motor cars, and can directly mutually be interchanged with a mechanical platinum breaker.
