tur·bo·charg·er – [tur-boh-chahr-jer]

noun

A form of a supercharger that is driven by a turbine, turned by exhaust gases from the engine. The turbocharger increases the density of air entering the engine to create more power.

It’s cheaper because – Ford has paired up the dual turbo chargers with a Direct Injection fuel system. It delivers the fuel directly to each individual cylinder, in a fine, controlled and highly accurate mist. Meaning less waisted gas!

It’s powerful because – In the past you had Turbo Lag Now you have responsive power! Turbo lag is the time it takes from the moment you press on the gas pedal to the time the turbocharger delivers the increased power. Turbo “Lag” is very common in single turbocharged engines. With Fords EcoBoost, they utilize 2 smaller turbochargers, boosting the combustion pressure at an even faster rate. Giving you the “On Demand” results you look for.

Why should you have it? – Environmentally friendlier, very fuel-efficient, very powerful, and very cost-effective. Popular Mechanics

  • Ford has built the first of a new breed of turbo engines designed to improve fuel efficiency. In the past, turbocharged engines have been used to boost power rather than save fuel. They ran at efficiency-killing low compression ratios and rich air/fuel ratios to prevent meltdowns. The 365-hp* 3.5-liter EcoBoost V6 uses several tricks to overcome these limitations. For instance, the direct fuel-injection system squirts fuel into the combustion chamber instead of the intake ports — this cools the chamber, allowing for a fairly high 10.0:1 compression ratio. The new V6 debuted in the Lincoln MKT and MKS, and the Ford Taurus SHO.
