Fuel Injection Systems
While it seems there has been some movement on the technology from in fuel injection with the new FADEC systems that continental and Lycoming are introducing. As we all know the typical fuel injection system is a crude at best setup......being a constant flow type.
Now the new FADEC systems introduce sequential injection where the fuel is squirted in only when the valve is open...or there abouts. But even that technology is 30 years old.
With most of the major automotive manufacturers adopting the direct injection method where the fuel is injected directly into the cylinder under enormous pressure, something like 26,000 psi. The engineers tell me it gains small but significant fuel economy gains.
Surely this principle would work in the aero engine context?
Any engineers want to comment?
