Scheme 32: Engine

The vehicle range is fitted with the "New Generation 2.0L Zetec-E engine". The most significant features are

  1. Hydraulic engine mountings
  2. 16 valve DOHC
  3. Full flow oil filter
  4. Aluminum alloy cylinder head
  5. Cast iron block
  6. High temperature resistant coating on exhaust valves
  7. Valve train with mechanical tappets
  8. Modified timing belt guide
  9. Aluminum timing belt cover with integral engine mounting function to reduce noise, vibration and harshness (NVH)
  10. Aluminum crankcase reinforcement and flat oil pan to reduce NVH
  11. Generator with check-back function for generator load

The changes made are

  1. close coupled tri-metal catalytic converter
  2. EGR system
  3. Adjustable valve tappets
  4. use of a cylinder head temperature (CHT) sensor in place of an engine coolant temperature (ECT) sensor.
