WHAT IS CHEVY DYNAMIC FUEL MANAGEMENT?
When you read about the 2019 Chevrolet Silverado 1500 over the next year or so, you might see a lot about Dynamic Fuel Management. This term will appear when discussing the engines and the capabilities of the pickup truck, but what is Chevy Dynamic Fuel Management exactly? In short, it is a cylinder deactivation technology which allows the engine to offer in 17 different cylinder patterns. Why is this important? Continue reading for more details.
What Dynamic Fuel Management can accomplish
An engine equipped with Dynamic Fuel Management can operate in those different cylinder patterns in order to better optimize the power and efficiency of the vehicle. A form of this was first introduced in 2005 as Active Fuel Management, and Dynamic Fuel Management is an evolution of this breakthrough in efficiency technology.

Active Fuel Management is able to operate between eight- and four-cylinder modes, which is great in and of itself. Dynamic Fuel Management ups the ante to 17 different patterns which means the engine is constantly working to deliver optimal performance and efficiency. This functionality is powered by a controller which is constantly looking at how the accelerator pedal is moving. From there, it runs so many calculations that it’d make Einstein’s head spin and finds out how many of the cylinders need to be used in order to meet the torque the driver is essentially requesting based on how hard the accelerator pedal is being pressed. This happens a staggering 80 times per second! An electromechanical system controls the valve actuation by activating and deactivating the engine’s 16 hydraulic valve lifters and uses solenoids (coils wound into helixes) to bring the necessary oil pressure to control ports in the lifters to activate and deactivate the latching mechanisms on the lifters to allow the valves to open and close.
What do you think about this technology? It’s exciting to think that even big and mighty vehicles like the Silverado 1500 pickup truck can still operate with fuel efficiency, getting every bit of value out of your fuel dollar, while still retaining the kind of power you need to get the job done.
