Ignition device for internal-combustion engine

Abstract

Abstract PURPOSE:To reduce the energy transmission loss of an ignition coil due to elimination of a high voltage cord by distributing power between an ignition coil and an ignition plug through a distribution plate thereby simplfying the device and improving the mountability. CONSTITUTION:Four planar electrodes 4A-4D formed with predetermined pattern are burried in a distribution plate 2 for the purpose to wiring between respective high voltage terminal 1a-1d of respective ignition coil 1A, 1B and respective ignition plug 3A-3D while springs are fixed through ribets 5, 6 to the opposite ends of said electrodes 4A-4D facing with said terminals 1a-1d and plugs 3A-3D. Then the high voltage produced alternatively at the secondary side of respective coil 1A-1B is fed from said terminals 1a-1d through respective spring, and said electrodes 4A-4D to said plugs 3A-3D to produce the firing spark. Since high voltage cord is not required, the reliability can be improved.
