  • Internal combustion engine ignition device
    Patent number: 4315493
    Abstract: The disclosed ignition device for a four-cylinder engine includes an ignition unit performing the ignition function in response to ignition signals. A rotor and a stator disposed in a metallic housing to serve to generate the ignition signals include four protrusions and three protuberances respectively. By rendering the number of the protuberances smaller than that of the protrusions, a space is left in the housing. Two bearing seats are disposed in the space at the opening of the housing and the ignition unit is screwed to the bearing seats.
