Tula Technology hits milestone of 1M vehicles produced with Dynamic Skip Fire

Green Car Congress

The result is that the engine dynamically fires the optimal number of cylinders to maximize fuel economy while maintaining a smooth ride with commercial levels of noise and vibration. Because each combustion event is selected to allow optimal efficiency, DSF reduces fuel and CO 2 , and for diesel applications, NO x emissions.
