Ford Engines: 3.5L with Ecoboost Twin Turbos

Ford Engines new EcoBoost  technology comes  from two small components with plenty of appeal for fans of fuel-efficient performance engines.

They are turbochargers, which harness exhaust gas to pump more power out of a smaller-displacement engine. The new 3.5-liter EcoBoost V-6 engine uses twin turbochargers – in conjunction with direct fuel injection – to provide more power than it’s size would indicate. It produces the horsepower and torque of a 4.6-liter, normally aspirated V-8 while delivering the fuel efficiency of a normally aspirated V-6 engine.

As an example, the 2010 EcoBoost Flex boasts the leading automotive fuel economy among full-size performance crossovers with 22 mpg highway and 18 mpg combined.

Twin Honeywell GT15 turbos are fitted to each EcoBoost V-6, one for each bank of the V-6. Exhaust gas flowing through the turbocharger spins a turbine wheel at very high speed, which drives a compressor turbine on the clean air side of the turbo. This fan effect densely packs intake air into the engine, compressed air up to 12 PSI that results in increased compression and performance.

A turbo is basically a large air pump, increasing the mass of air in the engine increases its power output, and that’s why it’s called ‘boost.’

Two small turbos is better than one large.

The new EcoBoost engine strategically uses two small turbochargers rather than one larger one. This is to fight turbo lag, the tendency for earlier turbocharged engines to have hesitation at low engine revs while the turbocharger spun up to its operating speed.

The EcoBoost V-6 is the first application of twin turbos in a Ford.

EcoBoost’s smaller turbines are quick to respond to throttle inputs, spinning up asap. Married  to the direct fuel injection system, turbo lag in the EcoBoost V-6 is not noticable and torque output is excellent, peaking earlier in the rev range than a comparable, normally aspirated V-8.

EcoBoost gives the driver a very flat torque response. You get peak torque across a very wide engine speed range, which is usable performance that’s available to you when you pull away from a stoplight or pass someone on a secondary road. You don’t need to wind the engine out to get performance out of it. It’s there all the time.

Hi-tech electronic controls, including active turbocharger waste-gate control, work in conjunction with throttle control to balance boost and torque levels very precisely. The system has eliminated turbo “whine” that characterized some earlier-generation turbo engines.

Engineered for reliable performance

The EcoBoost turbocharger system is engineered for long-term reliability, incorporating integrated water cooling to protect the internal turbo bearings in the high-temperature operating environment. The water cooling system prevents the ailment known as oil coking, in which earlier oil in -generation turbo bearings would bake and solidify, causing premature bearing failures.

Ford engineers have put the EcoBoost engines through a variety of rigorous testing procedures on both engine dynamometers and in real world environments. Drivability, cold starts, high-altitude running and trailer towing are improved.

The new 3.5-liter EcoBoost V-6 is offered initially as a premium engine for the 2010 Lincoln MKS and the 2010 Ford Flex, but the turbocharged Ford EcoBoost strategy is spinning up for more fuel-efficient, performance-rich engine products. By 2013, more than 90 percent of Ford’s North American vehicle lineup will offer EcoBoost technology.
