Abstract: At least some embodiments of present disclosure direct to a fuel injection timing drift detection and/or compensation system. In some cases, the system collects or receives a series of fuel pressure data measured by one or more fuel pressure sensors. The system is configured to receive an indication of fuel flow cutout and a start-of-injection command signal. The system calculates a set of pressure drops using the series of fuel pressure data and identifies a selected pressure drop greater than a predetermined threshold to determine a measured start-of-injection timing based on the selected pressure drop. The system is further configured to evaluate whether a fuel injection drifting occurs based on received start-of-injection command signal and the measured start-of-injection timing. In some cases, the fuel injection drifting is used to either compensate fuel injection timing or raise a flag indicating the drifting.

Abstract: A system includes an exhaust aftertreatment system including a particulate filter and a controller. The controller is configured to: receive information comprising a temperature regarding a filter of the aftertreatment system; and responsive to determining that the temperature regarding the filter is below a temperature threshold, command the engine to operate according to a first firing fraction. The first firing fraction may define a number of active cylinders of the engine relative to a total number of cylinders of the engine, and correspond to a predetermined temperature value of the filter.

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.
