Abstract
To decrease spark advance upon high-speed operation of a separately ignited internal combustion engine, a spark advance centrifugal timing element, engaging a timing cam, is constructed to be formed of two link elements connected together by a knee joint having a limit position defined by a stop and biased to be normally in that limit position but, upon excessive deflection upon high-speed operation of the engine, permitting breaking of the knee joint counter the bias force so that one of the elements, namely the one engaging the spark advance cam, can deflect with respect to the other and effect some spark retardation with respect to the previously commanded spark advance.
