ABSTRACT:
The fuel injected two-cycle internal combustion engine having an exhaust control valve and direct cylinder injection. The fuel injection timing and duration are increased at starting over idle and the exhaust control valve, which is normally closed at idle and opened at high speed is moved to its high speed condition during starting to assist in starting. In addition, when the engine is returned to an idle condition after racing, the engine idle speed is reduced in steps to prevent stalling and improve return to idle.
