MAGNETIC CIRCUIT APPARATUS FOR AN ELECTRONIC IGNITION SYSTEM OF A COMBUSTION ENGINE |
摘要 |
<p>MAGNETIC CIRCUIT APPARATUS FOR AN ELECTRONIC IGNITION SYSTEM OF A COMBUSTION ENGINE Magnetic circuit apparatus for use in an electronic ignition system of a combustion engine having one or more spark ignition devices comprises a magnetically permeable frame on which is supported a field magnet and a Hall Effect pulse generator in spaced apart relation such that the field magnet and frame provide a magnetic flux path to which the pulse generator periodically is exposed to produce successive pulses in timed relation to the speed of operation of the engine. A bias magnet confronts the pulse generator at that side of the latter which is opposite to the field magnet and has a polarity opposite that of the field magnet. The flux density of the bias magnet is substantially less than that of the field magnet.</p> |
