Abstract
Approaches to control engine overspeed are provided. Engine overspeed is controlled by one or more mechanisms that operate the intake and/or exhaust valves of the engine to interrupt the combustion cycle. In use, the 'combustion interrupter' mechanism(s) actuate the intake and/or exhaust valves according to, for example, one or more control strategies in order to interrupt the combustion cycle and/or cause the engine to expend energy to move the pistons through a complete cycle in an aim to retard engine speed. The engine's cam(s) can include one or more sets of variable valve timing lobes that operate the intake and/or exhaust valves of the engine in order to, for example, interrupt the combustion cycle. The combustion interrupter mechanism can additionally or alternatively include one or more computer controlled actuators that operate the intake and/or exhaust valves in order, for example, to interrupt the combustion cycle.
