Abstract
A control strategy for a throttled inlet oil pump that supplies high-pressure oil to a rail that serves fuel injectors of a diesel engine. A processor processes certain data to develop data for selectively restricting the throttle at the pump inlet. The processor develops error data defining error between a desired injector control pressure in the rail and actual injector control pressure in the rail. For a prevailing value of the error data, the processor adds a correlated offset data value to introduce an offset into the prevailing error data value, thereby creating an offset error data value. The processor further processes the offset error data value to create a value for the data that establishes the throttle restriction.
