Abstract: A system comprises a generator and an engine coupled thereto. The engine is configured to provide mechanical power to the generator. A controller is coupled to the engine and the generator and is configured to compare an engine operating parameter value to a load demand value indicative of a load exerted by the generator on the engine. The controller determines that the engine operating parameter value fails to match the load demand value. The controller determines an engine operating parameter threshold value at which the engine operating parameter value failed to match the load demand value, and sets the engine operating parameter threshold value as a maximum allowable engine operating parameter value for the engine.

Abstract: A system for controlling one or more conditions associated with combustion events in one or more cylinders of an engine while generally maintaining a spark timing value at a relatively constant value. The system includes a controller configured to determine one or more temporary adjustments to the spark timing value that brings one or more conditions, such as, for example, engine knock levels and/or NOx levels to around, or within, a corresponding target or threshold level(s). Following selection and implementation of one of the adjustments to the spark timing value, the controller implement adjustments to the adjusted spark timing value to return to a target spark timing value. The controller can further be adapted to determine adjustments to the air-to-fuel ratio to accommodate operation of the engine at the target spark timing value while maintaining the one or more conditions at or below the corresponding threshold or target level(s).

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: Methods and systems for diagnosis and control of an internal combustion engine using vibration data obtained from a vibration sensor mounted on the engine includes filtering vibration data within a predetermined engine combustion time period, where the vibration data is indicative of a vibration of an internal combustion engine, determining a peak cylinder pressure (PCP) of a combustion cycle of the internal combustion engine based on the filtered vibration data, determining a location of peak cylinder pressure (LPP) of the combustion cycle of the internal combustion engine based on the filtered vibration data, where the PCP and the LPP are indicative of a performance characteristic of the combustion cycle, and modifying an ignition timing of the internal combustion engine based on the determined PCP and LPP.

Abstract: Systems and methods to control the vehicle speed of a vehicle includes a controller communicatively coupled to a motor and a brake mechanism. The controller is structured to receive an indication of a desired change in the vehicle speed, activate a motor speed governor responsive to the brake mechanism being in a released state, adjust an output torque responsive to the vehicle speed, wherein as a load corresponding to the motor increases the vehicle speed decreases.

Abstract: A system for determining a state of health (SOH) of an energy storage device comprises a controller configured to be coupled to the energy storage device. The controller is configured to determine a current value drawn by or supplied to the energy storage device over a predefined period of time. In response to the current value not satisfying a current threshold, the controller determines a current gain factor and determines an adjusted current value from the determined current value based on the current gain factor. The controller is configured to determine an estimated SOH of the energy storage device based on the adjusted current value, and indicate the estimated SOH on a user interface.
