摘要

Cylinder deactivation controls, which turn off a fixed number of cylinders when an engine is operating at low loads, boost fuel efficiency by minimizing pumping losses in gasoline engines. A more sophisticated version of the technology debuted last year in the Chevrolet Silverado and GMC Sierra full-size pickup trucks powered by 5.3- and 6.2-liter V-8s. Several other General Motors trucks are adding the technology this year. Developed by Silicon Valley startup Tula Technologies, the system controls each cylinder individually to more precisely match engine output with torque requests. This can provide fuel efficiency gains of 7%-15% over a standard engine, which is about twice the improvement gained by current two-mode deactivation systems.
