  • Control Of The Air-Fuel Ratio Of Carburetors (AREA)
  • Electrical Control Of Air Or Fuel Supplied To Internal-Combustion Engine (AREA)

Abstract

PURPOSE: To make it possible to perform the air-fuel ratio control with a fixed latitude of compensation covering the whole engine operation range by a method wherein the bleed air to be mixed with fuel and the bypass air to be supplied to the air fuel mixture passing through a throttle valve are both controlled according to the exhaust gas concentration.
CONSTITUTION: A valve body 26 of the control valve 10 controlling the bypass air is inserted into the bypass air passage 25 connecting the air cleaner A or the upstream of the Venturi 15 and the downstream of the throttle valve 24. The valve plug 27 of the control valve 10 opens the passage 25 separating the valve 27 from the valve seat 30 when moving en bloc with the plunger 29 inserted into the center of electro-magnetic coil 28 to feed control current to the electro-magnetic coil 28, to supply the downstream side of the throttle valve 24 with air through two jets 31, 32. Also in the downstream of the control valve 10, an adjusting passage 34 is branched having a jet 33 from between two jets 31, 32 to be opened into the side of the throttle valve 24 in a totally-closed position or at a point a little upper stream.
