  • Engine with air-cooled non-contact ignition system
    Patent number: 4134370
    Abstract: A V-shaped, air-cooled engine is provided with a cover on the front thereof, which houses a cooling fan connected to the engine's crankshaft. The interior of the cover is fitted with dividers to separate the air flow and direct it to the opposite sides of the engine, and to form a compartment for housing components of a non-contact ignition system. The non-contact ignition system is operated by the cooling fan, and is cooled by the flow of air through the cover. Components of the ignition system are permanently connected to each other, without the usual separable connectors.
