Abstract
A fuel supply device for an internal combustion engine having at least two groups of combustion chambers, each group having a separate exhaust pipe, comprises a carburettor which delivers a mixture whose air/fuel ratio is adjusted responsive to the composition of the exhaust gases of the 'richer' group. The carburettor is connected to a manifold having two branches each associated with one group. The branch feeding the 'leaner' group is provided with an air/fuel ratio correction circuit comprising a solenoid valve controlled by a circuit whose input detector is located in the exhaust pipe of the 'leaner' group.
