Yes....or similar to what we have now at least. In a normal injected engine the fuel is sprayed on the back side of the intake valve as it opens. This allows the fuel to mix with the air and swirl into the chamber, be compressed and ignited. With direct injection the fuel is injected directly into the combustion chamber at the precise moment it is needed. Then it is ignited and away you go. This is far more economical as every drop of the fuel is used in the cylinder. The older type wastes a certain percentage due to how it is injected. You will also see cleaner engines because of this system too. F1 cars have been using it for years. Ford is also playing with engines that do not have a cam shaft. Valves are operated by solenoids instead. Efficiency is way up on these engines but thy are still a bit pricey for the general public. Again F1 engine have had this stuff for years. That's how they can attain 18K RPM. The moving parts are down to a minimum.
Taurus SHO 3.5L EcoBoost engine
I clipped this from one of the ads presented here...
Is this high compression, direct injection something along the lines of a diesel?The 3.5L EcoBoost™ is the first North American production twin- turbocharged direct-injection V6 engine. And Taurus SHO is the first and only vehicle in its class to feature the EcoBoost engine.* This engine provides better fuel economy** and fewer emissions as compared to a V8. EcoBoost combines two different technologies – turbocharging and direct-injection – to deliver the performance of a much larger engine with the fuel economy of a smaller engine.** It churns out 365 horsepower and 350 lb.-ft. of torque across a wide 1,500 – 5,000 rpm range. And it does all that with an estimated 17 city/25 highway fuel economy.** Compared to a naturally aspirated engine, the 3.5L EcoBoost twin-turbocharged direct-injection V6 engine provides higher performance, better fuel economy** and fewer CO2 emissions: • Improved transient response enabled by the direct injector reduces “turbo lag,” overcoming the traditional disadvantage of downsizing and boosting • More efficient fuel consumption is the result of a high compression ratio enabled by direct injection, which provides air charge cooling
