The world wide increasing demand for personal transport must be satisfied with consideration for the local and global environments. Therefore the major driving forces for powertrain improvements will be legislation, focused on the reduction of CO2 and noxious gas emissions, and customer perceived value. This paper discusses the detailed design, application and operation of Cylinder DeActivation technologies developed by Lotus and INA. The results, demonstrated from using this Cylinder DeActivation system on an existing engine, show reduced engine friction, reduced pumping losses, improved lean-burn or EGR tolerance leading to reduced noxious gas emissions and a reduction in real world fuel consumption of 10-20 %. All of these advantages are available now with reliable, production ready components that can be incorporated into existing or new engines.
