PRETORIA, South Africa, 21 February 2012 – The new Ford Fiesta features Ford Motor Company’s innovative 1.0-litre EcoBoost® engine and while it is one of the smallest displacement engines Ford has ever built, it is not short on power or refinement.
For the new three-cylinder engine to be successful, engineers knew they needed to build a no-compromises package. It could not force customers to choose between performance and economy or responsiveness and smoothness. It had to deliver it all.
The innovative powerplant does just that and as a result has already been selected for both the Popular Mechanics 2012 Breakthrough award and Engine Technology International’s “International Engine of the Year” award in Europe.
Not only does it emit just 99g/km of CO2, thus not being subjected to South Africa’s environmental tax levy, and utilise only 4.3l of petrol per 100km* on a combined cycle route, it does so without sacrificing on performance.
In fact the opposite is true. Despite its diminutive size, the 1.0-litre EcoBoost offers performance normally associated with much larger displacement engines. With 92kW and 170Nm on offer the 1.0-litre EcoBoost dispatches the 0-100km/h sprint in 9.4 seconds.
EcoBoost is fundamental to Ford’s strategy to provide technologically advanced, high-output, smaller-displacement powertrains that deliver uncompromised performance and fuel economy. EcoBoost engines deliver fuel economy gains of up to 20 percent and reduction of CO2 emissions of up to 15 percent, compared with larger, less-efficient engines. Ford’s leadership with EcoBoost has resulted in more than 125 patents on the technology.
Start up Ford’s patented new 1.0-litre EcoBoost engine and chances are you’ll have to look at the tachometer to verify that the engine is running.
The traditional way of reducing shaking forces in small-displacement engines is to install a counter-rotating balance shaft inside the motor that cancels out most vibrations. But balance shafts are heavy and expensive and would thus reduce the fuel efficiency.
The engineering team therefore found a different solution. They focused on two areas – the engine’s front pulley and the rear flywheel, and the mounting system that connects the powertrain with the car’s body.
The pulley and the flywheel are unbalanced with weights that are placed precisely to counteract the natural shaking forces of the engine and drive the energy in a less sensitive direction. The engine mounts are designed to decouple as well as absorb the engine’s shaking forces.
The result is one of the smoothest and quietest engines in Ford’s global line-up.
The smoothness of the engine is complemented by class-leading quietness. A super-compact, highly stiff cast-iron block structure and an integrated engine mounting bracket are crucial in absorbing noise energy. In addition to immersing the engine’s toothed rubber timing belts in oil, isolated fuel injectors electronically controlled for soft landing and a foam-covered engine collectively help keep noise and vibration from reaching the driver.
