Abstract
Cylinder deactivation is a means of improving the fuel economy of gasoline engines. This paper covers the application of the technology to a V8 engine and implementation into vehicles. The description of the engine hardware and its operation are discussed. The engine and transmission control strategy are described, including an example of the compensation strategies to smooth the transition between the different modes of engine operation. The powertrain and chassis hardware changes required to address the noise vibration and harshness issues are discussed and examples of untuned systems are shown.
