Abstract: One embodiment is a system comprising an internal combustion engine including an output shaft, a pulley system structured to be driven by the output shaft, a first alternator and a second alternator structured to be driven by the pulley system, and an electromagnetic clutch integrated within one of the pulley system, the first alternator and the second alternator and structured to selectably couple and decouple at least one of the first alternator and the second alternator from the output shaft. The system includes a controller in operative communication with the internal combustion engine system and structured to evaluate power demand and power production capability parameters of the system and to control the electromagnetic clutch to engage or disengage in response to the evaluation.

Abstract: An apparatus, method, and/or system is provided for conducting an engine shutdown in a circumstance of a runaway engine event. In a condition where an uncontrolled fuel source is present in the ambient air, there may be a risk of a runaway engine condition in an internal combustion engine. Air taken into an intake system of the engine may include an undesired or uncontrolled combustible component. The method, apparatus, and/or system includes steps, control systems, devices, and mechanisms to prevent opening of at least one intake valve or exhaust valve of at least one cylinder of the engine to stop combustion in the chamber, in response to a condition indicating a possible runaway engine event. The indicator may include an engine overspeed condition, or presence of the combustible component in the intake air.
