Patent
·
OSTI ID:6470467
A method and apparatus for controlling ignition system spark timing. It is detected whether the engine is in operation with no load or in the remaining operating conditions. A digital processor is provided which uses a mathematical formula or table during no load engine operation to find value of spark advance, which mathematical formula or table is distinct from a mathematical formula or table to be used during the remaining engine operating conditions to find value of spark advance.
