Acceleration enrichment for an engine fuel supply system

摘要

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.
