Abstract
A method includes detecting a diesel engine runaway event in a diesel engine and, in response to detecting the diesel engine runaway event, deactivating all cylinders in the diesel engine such that no combustion occurs in any cylinders of the diesel engine and no cylinders of the diesel engine produce power, wherein deactivating the cylinders of the diesel engine includes mechanically decoupling a camshaft of the diesel engine from inlet valves of the cylinders of the diesel engine, and wherein deactivating cylinders of the diesel engine prevents flow of air from an intake manifold into combustion chambers of the cylinders.
