What is the Ford EcoBoost® Engine?

The EcoBoost engine delivers powerful performance and better fuel economy than larger displacement engines. In most conventional engines, some energy is lost in the exhaust. But in the EcoBoost, the turbocharger uses the force of the exhaust to push more air into the engine, generating more power. This means a highly responsive drive with great low speed torque and outstanding overall performance.

Ecoboost Engines combine three technologies: 

Direct Fuel Injection. A high-pressure fuel system injects fuel directly into the combustion chamber, regulates how much fuel is needed at any given time, and cools the charge to enable higher compression ratios. This greatly improves efficiency while generating more power compared with a port-injected engine.

Variable Camshaft Timing. EcoBoost engines precisely control the intake and exhaust valves to match changes in engine speed and load. The result is improved fuel economy, reduced exhaust emissions, and increased low-end engine torque as compared to larger conventional engines.

Turbocharging. EcoBoost's lightweight design improves fuel economy, while fewer cylinders mean less friction and more energy saved. Yet, thanks to turbocharging and direct injection, EcoBoost delivers the power of a much larger engine.
