A system for increasing the amount of fuel injected into an internal combustion engine in response to an increase in the manifold absolute pressure greater than a predetermined amount and greater than a predetermined rate. The amount of enrichment is equal to a first value determined by the engine coolant temperature increased by a factor that has an initial value determined by the rate of increase in the manifold absolute pressure and that is varied toward unity at a rate determined by engine temperature. The duration of acceleration enrichment is determined by the amount of change in the manifold absolute pressure and the engine coolant temperature.

A fuel supply system for an internal combustion engine that is characterized in that its steady state operating fuel requirements vary from its transient operating fuel requirements, the fuel supply system comprising: sensor means effective to measure the values of predetermined engine operating parameters, including engine temperature, indicative of engine fuel requirements; means responsive to the values of the predetermined engine operating parameters effective to generate a base fuel signal representing the steady state engine operating fuel requirements; means effective to sense transient engine operating conditions representing increasing power demand; means responsive to the measured value of engine temperature and a sensed transient engine operating condition effective to generate an enrichment signal that is equal to a first value determined by engine temperature and increased by a factor having an initial value that is determined by the magnitude of the sensed transient engine operating condition and that is varied toward unity at a rate determined by engine temperature; and means effective to supply fuel to the internal combustion engine in accord with the base fuel signal and the enrichment signal to thereby provide fuel to the engine substantially in accord with its requirements during both steady and transient engine operating conditions.
