Abstract: A system for controlling operations of an engine comprises a plurality of cylinders and a controller operatively coupled to each of the plurality of cylinders. The controller is configured to determine an operating condition of the engine, and in response to determining that the operating condition is suitable for activating less then all cylinders of the plurality of cylinders during a cycle of the engine, determine a first firing pattern, and a second firing pattern different from the first firing pattern for activating the plurality of cylinders of the engine. The controller is configured to activate a first set of cylinders of the plurality of cylinders based on the first firing pattern, and subsequent to activating the first set of cylinders, activate a second set of cylinders of the plurality of cylinders different from the first set of cylinders based on the second firing pattern.

Abstract: A system includes a valve actuation system, a pre-lubrication pump coupled to a lubrication circuit and configured to provide oil to the valve actuation system, a catalyst for receiving and treating exhaust gasses, and a controller. The controller is configured to identify an engine start request and determine whether the catalyst temperature is below a first threshold value. In response to determining that the catalyst temperature is below the first threshold value, the controller actuates the pre-lubrication pump to direct lubricant to the valve actuation system, controls the valve actuation system to deactivate at least one cylinder of an engine, and, subsequent to deactivating the at least one cylinder of the engine, cranks the engine.

Abstract: A system is configured to store a relationship data set of a plurality of diagnostic estimators and a plurality of failure modes, each failure mode represents a type of failure that can occur with a sensor or a vehicle component of a vehicle system, each diagnostic estimator is associated with a respective subset of the failure modes, each subset defines a control space within the vehicle system that contains at least one of (i) one or more sensors or (ii) one or more vehicle components. The system is configured to store a healthy diagnostic vector regarding nominal operational parameters of the vehicle system; acquire diagnostic information regarding current operational parameters of the vehicle system to generate an error diagnostic vector; apply the error diagnostic vector to the healthy diagnostic vector to generate a ratio diagnostic vector; and apply the ratio diagnostic vector to generate a value for each failure mode.
