Overview of Ford Eco-Boost Engines

Since 2009 Ford has been producing EcoBoost engine and it is advertised as a family of turbocharged, direct-injected gasoline engines. This engine is also co-developed by German company FEV engineering.

These Ford engines are designed to deliver horsepower and torque close to if not surpass those of larger displacement, naturally aspirated engines, all while achieving 30% better fuel efficiency and 15% lower green house emissions. Ford vison these engines as less costly and more versatile than further developing hybrids and diesel engines technologies. As such, Ford uses EcoBoost extensively across a very broad range of vehicle product lines.

The most common version of EcoBoost engine currently is the 1.0-L turbocharged Inline three cylinder engines. It is initially built in two versions, 74kW (99hp) and 120-125PS (118-123hp).The more powerful version delivers a maximum of 170Nm of torque and 200Nm on over boost across 1400-4500rpm. A 138hp version has also been released in the Fiesta Red and Black Edition, with 210 Nm of torque. The block is made with cast iron, which posses 50% faster warm up speed compared to aluminum at the expense of additional weight.

Mentioned by Steve Gill, Ford’s Chief engineer, the 1.0-L three cylinder engine has three breakthrough that he is proud of. The first being efforts made in the flywheel design to compensate with the natural unbalance of three cylinder engines. Moreover, The engine uses an internal timing belt. Different from conventional timing belt, this belt is inside the engine, running in engine oil as engineers at Ford found that this can enhance lifespan and efficiency while eliminating timing belt squeak and noise. This unconventional belt also does not need replacement and is maintenance free. Furthermore the Ford EcoBoost 1.0-L engine also has an exhaust manifold cast into the cylinder head, reducing warm up times and is cooled by water cooling the engine block, all this, in an engine block the size of an A4 paper, specially coated to reduce friction in the engine. Ford also gave us the 65hp and 80hp versions with the 2013 Ford Fiesta. Both engines uses direct injection and Ti-VCT like the turbocharged variants, complete with start- stop technology to further improve fuel economy. Inline-4 engines with similar technology are also produced, including the 1.5-L, the most frequently modded and raced 1.6L packed with 160hp, 2.0L and also 2.3L.

The Ford F-150 is equipped with a twin turbo 2.7L- 60˚ V6 EcoBoost engine. It delivers 325hp(242kW) and 375lb.ft (508Nm). Ford invested half a billion dollars in the Lima ford Engine Plant for this new engine. This version also includes the 3.0L twin turbo, 3.5L Twin Force that designed to deliver power and torque equivalent to a typical 6.0L or larger V8 engine all while having at least 15% better fuel economy. In the MKR, this concept engine is rated at 415hp(309kW) and 400lb.ft(542Nm) of torque, running on E-85. The fuel delivery of this engine can attain high fuel pressure of up to 2150psi and two BorgWarner turbochargers that can spin up to 170,000 rpm and provide 12psi of boost. This engine can consume up to 25% more air over the N/A engine counterpart.
