The initial inspiration for Tula’s strategy came from an unlikely source: the human heart.

“Nature has figured out the most efficient way to do things. When the human body needs more power, the heart pumps faster. But even at low power requirements, the heart always pumps at peak efficiency. Why can’t we do the same thing with the internal combustion engine?”

From that simple question- not to mention years of persistence and hundreds of patent applications- Tula developed the technologies that would leverage existing powertrain systems to boost fuel efficiency by 7-15%.

And this approach of delivering varying levels of torque on demand, but always with peak engine efficiency, is applicable to emerging powertrain technologies, including electrification, advanced combustion and autonomous applications.

Internal combustion engines are going to be around for a long time. Making them more efficient is our mission, and our passion.

Vehicle Fleet through 2050 by Powertrain

Vehicle Fleet graph

Even the most aggressive electrification forecast from Morgan Stanley, International Energy Agency, Goldman Sachs, Bloomberg, and Tula’s own research shows the internal combustion vehicle fleet in 2050 at close to a billion vehicles.

DSF can be applied synergistically with hybrid electrification, autonomous, and even advanced combustion technologies.

Tula and DSF will impact the fuel efficiency of internal combustion engines in a variety of pathways.
