How Dynamic Skip Fire Works - The Ultimate Cylinder Deactivation
EE Shirts!

Dynamic Skip Fire is a new Tula/Delphi technology that aims to be the ultimate form of cylinder deactivation. It allows for fully variable cylinder deactivation, meaning if you have a V8 engine, it can run on one cylinder, two cylinders, or any number of cylinders up to all eight cylinders.

This video will explain how the cylinder deactivation works, what the advantages are, pumping losses, and what real world efficiency benefits can be expected. The majority of the benefit of this system comes from reducing pumping losses. That is to say, it's more efficient to run one cylinder at high load for a certain amount of power, versus running four cylinders at low load for that same amount of power.

Dynamic Skip Fire technology will make it's debut in the 2019 Chevrolet Silverado with 5.3L and 6.2L V8 engines, called "Dynamic Fuel Management."
