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.
