Tula DSF Cylinder Deactivation Technology

[DSF Technology Helps Boost Fuel Economy]

Many car engines use cylinder deactivation technology to make their engines more efficient. However, high capacity engines often suffer from power loss as a result of this process.

Now, a new system from Tula Technologies promises to rectify those weaknesses and offer significant fuel economy gains in heavy duty engines.

This technology, called Dynamic Skiip Fire (DSF) was tested on a 6.2-ltr V8 engine from GM and showed an 18% fuel economy gain when compared to GM’s stock deactivation technology.

It did so by allowing cylinder deactivation on a cycle-by-cycle basis, instead of the gear/RPM based system currently being used by GM. This allows the cylinders to be deactivated individually, on the fly, for better efficiency.

In addition, the system also increases air mass in firing cylinders to increase performance in the lower range, thus taking care of any power loss issues caused by the individual deactivation. This compensation helps reduce wear and tear, thus keeping the engine running smoother for longer.

Testing of this system through independent labs backed the claims of the company, while also highlighting lower emissions as an added bonus. The research and results are published on the SAE International website for review.

Now it is up to GM (a stake holder in Tula) if they want to use this system with their V8 engines, which are used in several different cars already. If they do, then be ready to enjoy better efficiency and a smoother drive experience.
