  • Two-cycle engine with exhaust temperature-controlled ignition timing
    Publication number: 20030106528
    Abstract: A two-cycle internal combustion engine has an ignition timing that varies with engine speed. A plurality of ignition patterns (the relationship between ignition timing and engine speed) are used. The engine exhaust gas temperature is sensed and is used to determine the particular ignition pattern used at a particular time.
