Ford 1.0-litre EcoBoost Technology Detailed


Just as the new 1.0 liter EcoBoost engine is getting ready to report for duty in Ford Focus – launching in B-MAX and C-MAX later this year – Ford releases more details on the innovative technologies used in this powertrain.

The second EcoBoost engine introduced into the all-new Focus, the 1.0-litre version combines turbocharging, direct injection and twin variable cam timing to deliver high levels of performance and refinement with all the fuel economy advantages of downsizing. To give you some facts and figures, it produces 125PS and 170Nm peak torque (200Nm with overboost) between 1,400 and 4,500rpm.

Meanwhile fuel consumption remain almost all the time above 50mpg. The 100 PS version does nearly 60mpg.

Thomas Zenner, Ford powertrain engineering supervisor, said: “With this engine there is no compromise: it delivers best-in-class fuel economy, outstanding driveability and excellent refinement – achieved by combining advanced features with smart engineering.”

The unique features of Ford’s 1.0-litre EcoBoost petrol engine include:

  • Small low-inertia turbocharger which increases torque and performance while minimising the lag in response during the acceleration process
  • Variable timing on both intake and exhaust camshafts allowing flexibility to optimise engine efficiency under all conditions
  • New water-cooled exhaust manifold integrated into the cylinder head to lower exhaust temperature and provide optimal fuel-to-air ratio even at high speeds for real-world fuel economy improvements
  • Offset crank and variable oil pump which increase efficiency and ensure the engine runs at optimum oil pressure across the entire speed range
  • High pressure solenoid direct injectors are located centrally providing a much cooler and denser fuel-to-air ratio, leading to more efficient combustion and reduced fuel consumption
  • Dual-split cooling system with two thermostats which supports a quicker engine warm up, reduced friction within the engine, lower fuel consumption and less emissions when engine is cold
  • Cambelt running in oil reduces noise and also reduces friction leading to fuel savings
  • Unbalanced flywheel/pulley.  Compact in-line three cylinder engines naturally develop a combined pitch and yaw motion (resulting in a booming noise).  Instead of introducing a conventional balance shaft to counteract this, the flywheel and crank pulley are intentionally “unbalanced” to offset the primary engine shaking forces
