Diesel MFI Pump: Description and Operation
Fuel Delivery
For good emission characteristics, the fuel must be metered in such a way that there is excess air even at full load. In addition, the fuel quantity must
be controlled so that engine speed does not fall below the predetermined idle speed, nor exceed the maximum allowable value. Adaptation to particular
operating conditions can require further corrections to fuel delivery.
