Abstract
A control system for controlling an air-fuel mixture to a preferable ratio required in an internal combustion engine during any of the engine operating conditions, which preferable ratio is variable in response to the engine operating condition. In one embodiment, the control system is arranged to regulate the amount of fuel, to be jetted into the intake passage leading to at least one combustion chamber of the engine through a main discharge nozzle, in response to the pressure of fuel vapor inside a fuel tank. In another embodiment, the control system is arranged to regulate the amount of fuel, to be jetted into the intake passage through one or both of the low speed port and the idle port, in response to the pressure of fuel vapor inside the fuel tank. The control system is usable in association with an internal combustion engine of any type having a fuel evaporation control system.
