Abstract : Cylinder deactivation (CDA) works by shutting off fuel, spark, and valves in an engine’s cylinders while it is under low load, which lets the other cylinders run more efficiently. This paper will go through the aspects of technology from the 1981 Cadillac V8-6-4, through General Motors’ modern Active Fuel Management and Dynamic Fuel Management systems, to the controlled Dynamic Skip Fire developed by Tula Technology. Pulling information from SAE test data and other research, this paper discusses cylinder deactivation’s fuel-efficiency benefit and how it affects emissions. It then reviews the durability concerns that followed after widespread adoption of the system and finishes by looking at how the shift led to improvements in technology and in performance.
