Abstract
A method and apparatus for protecting an engine from overheating. The apparatus comprises a cylinder head temperature sensor operably coupled to sense the temperature of the cylinder head and a control system operably coupled to the cylinders and the cylinder head temperature sensor such that when the temperature of the cylinder head exceeds a maximum level the control system deactivates one or more of the cylinders and rotates the deactivation of one or more engine cylinders such that no one cylinder is constantly fired thus providing engine cooling by drawing fresh air through the deactivated one or more cylinders.
