Abstract

PURPOSE: To prevent a reduction of output in a high load by providing a load detector in a feedback control system air fuel ratio correcting device for increasing fuel in the high load.
CONSTITUTION: An air fuel ratio detector 50 for detecting exhaust components and a condition detector 80 for detecting whether or not the detector 50 is operated are provided in an exhaust pipe 42 of an internal combustion engine 40 in order to send the respective signals to the input of a control circuit 100. An auxiliary air path 22 for intercommunicating the upper and lower flow of a throttle valve 14 in an intake pipe 41 is provided while a bypass valve 21 pivoted by a pulse motor 20 receiving signals from the circuit 100 is provided in the path 22. Also, an intake pressure detector 70 for detecting load is provided in the intake pipe 41 to send signals to the input of the circuit 100. A needle valve 16 operated by the circuit 100 moves upward in high load of the engine to open an auxiliary jet 18 for increasing fuel.
