CYLINDER CHARGE TRAPPING STRATEGIES BASED ON PREDICTIVE NUMBER OF SKIPS AND STAGGERED IMPLEMENTATION OF VALVETRAIN DEPENDENT OPERATIONAL STRATEGIES FOR INTERNAL COMBUSTION ENGINES

摘要

A system and method for controlling an internal combustion engine involving (1) cylinder trapping strategies where one of several pneumatic spring types are dynamically selected for cylinders based at least partially on a predicted number of upcoming skips for each of the cylinders respectively and/or (2) staggering various valvetrain dependent operational engine strategies as operating conditions permit as the internal combustion engine warms up following a cold start.
