![]() The engine operation is managed by Bosch MED17 control unit with CAN-Bus and individual cylinder knock control. That system also includes an electric water pump used for cooling the turbocharger even when the hot engine is turned off. ![]() The engine itself is cooled by a split cooling system with two thermostats and two circuits, one for the top end and turbocharger and one for the engine block. The charged air goes in a composite intake manifold through the air-to-air intercooler with an additional electric fan. The 1.0-liter version has a water-cooled, small, low-inertia, high-speed Continental turbocharger. The one thing, which makes Ecoboost engine so powerful, is a turbocharger. Each cylinder has a 6-hole solenoid injector which injects the fuel directly in the combustion chamber supplied by a high-pressure fuel pump. The engine has a Bosch high-pressure direct fuel injection system. The 1.0l EcoBoost is equipped with Ti-VCT (Twin Independent Variable Camshaft Timing). The timing belt warranty is 10 years or 120,000 miles (200,000 km). The low-friction timing belt-in-oil drive with dynamic tensioner provide quieter and more efficient running (about 20%) with the reliability of a chain. The engine has belt driven intake and exhaust camshafts (DOHC engine). The Direct Acting Mechanical Bucket (DAMB) valvetrain uses polished solid buckets (tappets). ![]() There are 4 valves per cylinder: two on the exhaust side and two on the intake side. The exhaust manifold is integrated into the cylinder head which lowers the temperature of the exhaust gases and warms up the engine more quickly at cold starts. On top of the block, there is an aluminum alloy 12-valve cylinder head. The 1.0l EcoBoost is equipped with an electronically controlled variable displacement oil pump. Ford engineers also improve the lubrication system to increase the efficiency of the engine. Inside the engine block, there is cast aluminum, low-friction coated pistons and forged connecting rods. The engine operates smoothly without spending energy on the balance shaft rotation. The unique unbalanced flywheel and front pulley allowed refusing use of a balance shaft. The crankshaft also made of cast iron, has 6 counterweights and 4 main bearings. Cast iron block is heavier than aluminum ones but reduces the amount of energy needed for warm-up by up to 50%. The 1.0 EcoBoost engine has an open-deck design cylinder block made from grey cast iron.
