Title:
IGNITION DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2015/059954
Kind Code:
A1
Abstract:
A contactless ignition device for a general purpose engine having no battery, wherein a primary coil and a charging coil both have the desired inductance and impedance, and the ignition device has a configuration that is small, simple, and highly reliable. A primary coil (L1) and a charging coil (LCH) are wound around a primary bobbin (57) through which a yoke is inserted, the coils (L1, LCH) constituting a coil portion (L). The primary coil is configured from a plurality of coils (L11, L12) connected in parallel, and the primary coil and the charging coil are connected in series. The charging coil and the primary coil configured from the plurality of coils are configured by selectively binding an intermediate part of a single conducting wire to a plurality of terminals (63a~63c) formed on the primary bobbin, without cutting the conducting wire partway through.
