GM introduces new Dynamic Skip Fire System, is basically next-gen cylinder ... - eGMCarTech

Computer-controlled engine ignition and timing has led to the introduction of unique internal combustion engine features such as cylinder deactivation. Now, there’s a new type of variable displacement that General Motors is introducing–it’s called Dynamic Skip Fire and is the American auto giant’s next step in fuel-saving technology. will result in a revolutionary new fuel economy technology that could be deployed in future gasoline engine-powered General Motors’ vehicles. Tula’s Dynamic Skip Fire (DSF) technology integrates advanced digital signal processing with sophisticated powertrain controls to create a software-based approach to variable displacement engines. Instead of relying on fixed cylinder deactivation or switching between fixed patterns like current multi-cylinder engines, Tula’s DSF technology continuously makes dynamic firing decisions on an individual cylinder basis to deliver the required... Independent testing commissioned by Tula shows that the application of DSF technology can improve fuel efficiency in a multi-cylinder engine (4/6/8 cylinders) by as much as 15 percent when compared to a vehicle equipped with an engine that does...
