  • Internal combustion engine ignition system
    Patent number: 4147147
    Abstract: A magnetic pulser having an energizing winding and a set of normally closed contacts is connected in the ignition system of an internal combustion engine with the contacts in series with the primary winding of the ignition system coil and the energizing winding of the pulser connected in parallel with the primary of the coil. The pulser includes a spring which biases the contacts toward a normally closed position and the strength of the spring is selected so that it is sufficient to resist opening of the contact set until the breaker points of the distributor are opened by the distributor cam.
