Abstract:
In a carburetor construction for metering liquid fuel for delivery downstream of the throttle valve to a spark-ignition engine, means are provided for remotely controlling the fuel-toair ratio including a rapidly operative mechanism for shutting off the fuel source during periods when the engine or vehicle is decelerating toward a predetermined minimum speed value.
Abstract:
A regulator provided with an inertia-block resiliently connected to a slidable pressure-responsive member controls automatically the feeding of fuel to the idling jet of a carburetor, in response to pressure variations in the inlet manifold of an internal-combustion engine. Consequently air pollution by unburnt fractions of the exhaust gases at idling speed and during deceleration is substantially prevented.
