FUEL CONTROL SYSTEM FOR AN INTERNAL COMBUSTION ENGINE

摘要

A fuel control system for an internal combustion engine of torch ignition type including a main combustion chamber and sub-combustion chamber, wherein an air/fuel mixture fed to said sub-combustion chamber is ignited by a spark plug to produce a torch which spreads into the main combustion chamber. The fuel control system comprises air/fuel ratio sensing means operative to produce a signal in response to the detected air/fuel ratio of the overall intake mixture and fuel flow rate correction means operative to correct the flow of fuel delivered from a fuel supply system responsive to the output signal of said air/fuel sensing means, whereby feedback control is provided to regulate the air/fuel ratio of the overall intake mixture toward a predetermined value.
