Abstract
A fuel supply control arrangement for use in an internal combustion engine, which is so adapted that, in the arrangement to decrease the air/fuel ratio, i.e., to enrich the air/fuel mixture at a specific operating region by increasing the amount of fuel supply, upon transfer into the specific operating region, the fuel is once increased to an amount more than a regular fuel amount for obtaining an air/fuel ratio set in the specific operating region, so as to be restored thereafter to the regular fuel amount, whereby undesirable leaning of the air/fuel mixture at an early stage of transfer into the specific operating state, arising from adhesion of fuel onto an intake passage wall surface can be prevented.
