New 2014 Silverado EcoTec3 Engine

DAVISON, Mich. - Aug. 16, 2013 - PRLog -- The 2014 Silverado's 5.3L EcoTec3 V-8 Engine offers the proven power and dependability of a regular V-8 truck engines, with better highway fuel economy than a leading competitor's smaller turbocharged V-6. It combines tested technologies like Active Fuel Management, Direct Injection and continuously Variable Valve Timing to provide class-leading fuel efficiency, with the peace of mind that comes with our reliable engine designs. No matter which EcoTec3 engine you choose, Silverado offers you a fuel-efficient and powerful way to power your Truck.

Direct Injection: Monitors a number of variables to determine the precise measure of highly pressurized fuel to inject into each cylinder. The result is combustion that optimizes engine power and fuel efficiency while reducing emissions.

Active Fuel Management: In low-demand situations when full engine power is not needed, Active Fuel Management deactivates cylinders, effectively turning a V-6 or V-8 EcoTec3 engine into a fuel-sipping four cylinder. When it senses the need for full power, AFM instantly re-engages all cylinders.

Variable Valve Timing: Ensures Silverado performs at optimum power and efficiency. It continuously varies valve timing to keep our EcoTec3 engines operating near peak output across a wide rpm range, while minimizing emissions.

So in simple terms: Direct Fuel Injection optimizes engine power and fuel efficiency while reducing emmissions; Active Fuel Management deactivates cylinders, effectively turning an EcoTec3 Engine into a fuel-sipping four cylinder; and Variable Valve Timing allows a peak output across a wide rpm range, while minimizing emissions. Only the Ferrari has these three options together in one engine, and I think that speaks volumes on its own.
