Abstract
An engine control system for a compression ignition engine employs a microprocessor-based controller that detects engine operation in a speed range previously determined to be undesirable, and responding to the detection by changing operation of the engine. In the preferred embodiment, the controller commands a parameter for adjusting engine operation to reach a different speed outside of first and second thresholds defining the undesirable range in a time period subsequent to the detection.
