System, apparatus, and method for controlling an engine system to account for varying fuel quality

A system, apparatus, and method for controlling an engine system can provide fuel reactivity compensation control for an engine of the engine system. The control can include controlling pilot fuel quantity supplied to an engine based on a pilot fuel offset value; and controlling air-to-fuel ratio (A...

More Information
Summary:A system, apparatus, and method for controlling an engine system can provide fuel reactivity compensation control for an engine of the engine system. The control can include controlling pilot fuel quantity supplied to an engine based on a pilot fuel offset value; and controlling air-to-fuel ratio (AFR) for the engine based on an AFR control trim value. A NOx error value can be used to generate one of the pilot fuel offset value or the AFR control trim value, and an exhaust temperature error value can be used to generate the other of the pilot fuel offset value or the AFR control trim value.
