DESCRIPTION AND OPERATION
Engine Engine emission control
Cross-mounted 16-valve DOHC engines with 59 European emissions level IV
kW (80 PS) and 74 kW (1 00 PS) respectively.
European on-board diagnosis (EOBD) for the
Valve train with mechanical bucket tappets monitoring of emissions-relevant components.
Cylinder block and cylinder head made of an
aluminium alloy
Diagnosis
Auxiliary drive via a self-tensioning belt without a
belt tensioner WDS diagnosis CD
817.
Instrument cluster (engine indicator lamp)
Engine management
Sequential multi-port fuel injection (SFI)
temperature and manifold absolute pressure (T-MAP) sensor in conjunction with a Siemens
powertrain control module (PCM).
Knock control
PCM with 84 pins and integrated passive anti-theft
system (PATS) immobiliser. Torquelpower
The Duratec 16V engines are characterised by
their high level of running refinement, low emission
levels and balanced development of power.
