Abstract
Provided is a system having a hybrid powertrain having a piston internal combustion engine, and a motor/generator, and the motor generator being coupleable to a clutch and thereby a gearbox, the engine further being equipped with a valvetrain control system operable to change the engine valve operation between a first mode in which the engine can operate in a conventional internal combustion mode and a second mode in which pumping losses are reduced when the engine is not operating in a conventional internal combustion mode.
