Lower fuel consumption thanks to cylinder shut-off technology

Automotive companies are striving to reduce fuel consumption in new models by downsizing their engines, which means replacing large propulsors by smaller but more powerful ones, reducing their service life. However, Tula has developed a more effective solution that reduces fuel consumption by turning off cylinders.

Big engines have to consume a lot of fuel, and although every automotive fan says there is nothing better than the V8 roaring, automotive companies are looking to cut back on fuel costs, replacing large engine units, with significantly smaller 6 or even 4 cylinders. Unfortunately, these engines are more advanced at that time, which increases their failure rate and increases the operating costs of such vehicles.

Tula has, however, developed a technology called Dynamic Skip Fire that reduces fuel consumption by turning off parts of the cylinder when the engine is running under lesser load. Although such systems have been used for years, Tula has come up with this concept a bit differently.

In the currently used systems, half of the cylinders are switched off during free driving. In the V8 engine, the computer system deactivates four cylinders, while three V6 cylinders are switched off in the V6. Why just half of the cylinders? Therefore, to keep the engine running at a level that would otherwise be subjected to powerful vibrations, and no driver would want the propulsion unit to jump out of the mask.

This problem is solved by Dynamic Skip Fire technology, which works on a similar principle, but instead of switching off a predetermined number of cylinders, this determines dynamically according to driving conditions. In other words, instead of turning off the V8 engine with four cylinders, you can turn them off seven.
