Abstract
A direct fuel injection outboard marine engine having an improved spark ignition system. This spark ignition system includes a magnetic core-coil assembly for generating a high-voltage signal within a short period of time and an electronic engine management module for energizing a primary coil of the magnetic core-coil assembly with a low-voltage signal at the appropriate time. The magnetic core is made of ferromagnetic amorphous metal alloy which exhibits low core loss and a permeability in the range of 100 to 500. The high-voltage signal is output by a secondary coil wound around a major portion of the core, with the primary coil being wound around a minor portion of the core. The secondary coil outputs a high-voltage signal to a spark plug in response to excitation of the primary coil with a low-voltage signal generated by the electronic engine management module.
