Abstract: A computer system includes a processor and a memory configured with instructions executable by the processor to determine a fuel configuration in response to input received by the HMI, determine fuel composition constituents in response to at least the fuel configuration, determine one or more fuel properties in response to at least one or more fuel composition constituents, determine one or more engine controller adjustments in response to the one or more fuel properties, and provide the one or more adjustments to an engine control system. A human-machine interface (HMI) is operatively coupled with the processor, and a memory and may be utilized to provide commissioning or service inputs.

Abstract: Control of an internal combustion engine system in response to a condensation condition associated with a charge air cooler is disclosed. One or more operating parameters of the internal combustion engine are monitored to the control charge air cooler coolant inlet temperature to keep the charge temperature above the estimated dew point to reduce or prevent condensation upstream of the intake manifold.

Abstract: A controller includes at least one processor coupled to a memory storing instructions that, when executed by the at least one processor, cause the at least one processor to: determine a target engine outlet coolant temperature for a coolant in an engine system; determine an adjustment to a temperature of the coolant based on a determined engine inlet coolant temperature and the target engine outlet coolant temperature; and, alter a flow of the coolant by controlling a coolant valve in response to the determination of the adjustment to the temperature of the coolant.

Abstract: Systems, methods and apparatus are disclosed for producing a target compressor outlet pressure that is based on a desired pressure differential across an intake throttle of an internal combustion engine and an intake manifold pressure by opening or closing a compressor recirculation valve and a turbocharger wastegate to commanded positions based on the target compressor outlet pressure.

Abstract: Control of a spark ignited internal combustion in response to an exhaust manifold pressure measurement of an engine is disclosed. An engine out NOx amount for at least one cylinder is determined at least in part in response to the exhaust manifold pressure measurement and a brake mean effective pressure of the at least one cylinder. An operating condition of the engine is adjusted in response to the engine out NOx amount.

Abstract: One exemplary embodiment is a system comprising a dual-fuel engine structured to selectably combust a first fuel type and a second fuel type, and an electronic control system in operative communication with the dual-fuel engine. The electronic control system is structured to control a transition of the dual-fuel engine from a dual-fuel mode to a single-fuel mode. After initiating the transition from the dual-fuel mode to the single-fuel mode, the control system stops provision of the second fuel type, requires combustion using control parameters configured for the dual-fuel mode until a transition ventilation condition is satisfied, permits non-emergency commanded engine shutdown only if the transition ventilation condition is satisfied.
