Ford's smallest EcoBoost engine, the 1.0 litre unit is known for delivering a high power output along with good fuel-efficiency despite a relatively smaller displacement. For has used the EcoBoost technology to significantly downsize its engine and in turn lower the vehicle weight, fuel-consumption and emissions without sacrificing on power. The company is now going to push the envelope further for the 1.0 litre EcoBoost engine as Ford engineers are working on equipping the engine with cylinder deactivation technology. The company claims that the new 1.0 litre EcoBoost engine three-cylinder with deactivation technology will be launched in early 2018.
This technology is primarily used in V6 or V8 engines, wherein two cylinders are completely shut from the ignition cycles when the engine is facing partial load. This lowers the amount of fuel being sent into the combustion cycle and hence increases fuel-efficiency. However, this is the first time this technology is being deployed in a three-cylinder engine. The testing of the engine is being conducted at the European Research and Innovation Centre in Aachen, Germany. The company is working on a prototype for a new dual mass flywheel that will help cylinder deactivation at a wider range of engine loads and speeds, with the engineering team at the Schaeffler Group. Preliminary tests suggest an increase in fuel efficiency of up to 6 percent and lower CO2 emissions. The company said that there will be no compromise on performance or refinement of the engine.
The cylinder deactivation automatically stops fuel delivery and valve operation in one of the cylinders under conditions where full power is not needed. The company will also tune the new engine mounts, drive shafts and suspension bushes for refinement as the engine switches between the two and three-cylinder modes. The EcoBoost engine will be durable to support the different loading forces from cylinder deactivation owing to a new camshaft chain, and valve rockers formed using advanced metal injection moulding.
The 1.0 litre EcoBoost engine is available in three states of tune, 98 hp, 124 hp and 138 hp, of which the EcoSport features the unit with 124 hp. Among multiple versions of the EcoBoost engine, there's a V6 engine, which powers the Ford GT.
