Claim 0:
1. A method to extend a life of a component of a cylinder deactivation (CDA) system, comprising:
generating, by a controller, an initial life factor for the component;
initiating, by the controller, a CDA mode for an engine;
determining, by the controller, an actual life factor for the component, the actual life factor determined by comparing a number of switching events of a cylinder in the CDA mode to a number of cycles of the cylinder in the CDA mode;
comparing, by the controller, the actual life factor to the initial life factor; and
modifying, by the controller based on the comparison, operation of the engine in the CDA mode to adjust the actual life factor.
