A combination for use in supporting and rotatably driving a mass is disclosed. The combination may have a power source. The combination may also have a flywheel, which may be configured to connect with and rotatably drive the mass. The flywheel may have a flywheel end, which may have a plurality of flywheel protrusions. Additionally, the combination may have a bearing, which may be situated at least partially within the power source. The bearing may be configured to support and at least partially house the flywheel. In addition, the combination may have a crankshaft, which may be shaped to connect with and rotatably drive the flywheel. The crankshaft may have a crankshaft end, which may have a plurality of crankshaft protrusions. The plurality of crankshaft protrusions may be shaped to mesh with the plurality of flywheel protrusions.

Combination to support and rotatably drive mass

An engine that is operating with a combustible intake mixture may begin in to runaway, or in other words, uncontrollably operate at excessive speeds. In order to shutdown a runaway engine, the present disclosure determines whether an engine is operating in a runaway condition. If the engine is operating in the runaway condition, a compression inhibiting mechanism is moved from a first position in which compression ignition can occur within at least one combustion chamber and a second position in which compression ignition cannot occur within the at least one combustion chamber.
