For the last few years, Ford has been touting its EcoBoost engine technology. If you're not quite sure exactly what it is -- or whether you should consider it -- you've come to the right place. We've provided an overview of the Ford EcoBoost system to help you better understand the complicated technology.
The simple explanation is that EcoBoost is a combination of turbocharging and direct fuel injection that improves fuel economy without sacrificing engine power. But that glossy overview hardly explains how the system really works.
One hallmark of Ford EcoBoost is its engines are turbocharged. Turbocharged engines use a device that forces in more air than a normal engine would receive. More air -- and more fuel -- makes an engine more powerful.
The device that forces this air into an engine is a turbocharger -- and some use the word "boost" to describe the process of turbocharging. That's where Ford gets the boost in EcoBoost. More important, turbocharging adds power without substantially decreasing gas mileage. That's different from simply enlarging an engine, which requires more fuel and hurts mileage.
The second part of Ford's EcoBoost engine is gasoline direct injection, or simply direct injection. Direct injection is one form of fuel injection, which is the process used to send fuel into an engine. While typical fuel injection uses an extra step known as the intake tract to inject fuel, direct injection cuts out that process entirely. The result is a less complicated fuel injection process, which improves efficiency.
