New range of engines will feature high-pressure direct-injection and turbocharging to get more power and efficiency from a smaller unit.

Sticking with the recent trend of 'less is more', Ford has unveiled its new series of EcoBoost 4-cylinder engines at the Frankfurt motor show today.

The engines feature high-pressure direct-injection technology, turbocharging and twin independent variable valve timing that will deliver more power and about 20 percent less C02 emissions than previous units.

Two 4-cylinder, all-alunimum engines, a 1.6 liter and a 2.0 liter unit, will come in various output configurations. The 2.0 liter engine will be used in the larger models in Ford's European lineup with power ratings at over 200 hp. The 1.6 liter will span the 150 to 180 hp power range while a yet-to-come smaller unit will cover output capacity under 130 hp. Ford is promising a smaller EcoBoost engine to come later for its compact and minicar models.

EcoBoost technology offers more lower-end torque for petrol/gasoline engines due to sophisticated turbocharging (with small rotors spinning at more than 200,000 rpm) which can achieve maximum torque at somewhere around the 1,500 rpm mark, similar to diesels. Ford says the engines will have a broad powerband stretching up to 5,000 rpm too.

The new 1.6 and 2.0 liter EcoBoost engines will be featured in European models starting in 2010. In North American, Ford has already introduced its V6 EcoBoost in the Taurus SHO.

Ford says it will build the 2.0 liter unit at its engine plant in Valencia, Spain while the 1.6 liter will be produced at the Bridgend Engine Plant in the U.K. Ford aims to produce about 1.3 million EcoBoost engines annually by 2012, 750,000 of them in the U.S.
