Twin air engine how does it work

Until then, however, we thought you'd like a closer look into the technologies which allow such a small engine to develop if not more, that at least as much power as much bigger engines available in Europe.

It basically ensures air control in spark ignition engines without using the throttle valve. Air, as you know, is one of the main ingredients needed by an engine to run. In conventional engines, the volume and pressure of the air in the cylinders is controlled with the help of the aforementioned throttle valve. This configuration makes the engine lose about 10 percent of input energy, used to pump the air from a lower to a higher intake pressure. Fiat TwinAir auto guide. Latest car models:.
