1. one kind regulates the method for the air fuel ratio of two-stroke crankcase scavenged explosive motor (1), in fuel supplies, divide the described air fuel ratio of adjusting in (8,80), described fuel supplies is divided such as for vaporizer or fuel injection system, and described fuel supplies divides (8,80) to comprise the control unit (80) for regulating described air fuel ratio;

  • Described motor (1) produces waste gas (42), and described waste gas comprises the gas being produced by air-fuel mixture participation burning and other gases that produced by scavenging;

    Described method comprises the roughly uniform step in mixture that oxygen content induction installation (81) is arranged on to described waste gas, and described method is further comprising the steps of;

    A) actual value of detection oxygen concentration induction installation (81);

    B) described actual value and desired value are compared;

    AndC) to regulate described air fuel ratio in response to the mode of described comparison, to reduce the difference between described desired value and described actual value.
