General
The 1.6L Duratorq TDCi (DV6) engine is a comprehensively revised version of the familiar 1.4L Duratorq TDCi (DV4) engine used in the Fiesta 2002.25.
The cylinder head has been completely re-designed. The exhaust camshaft is driven via a short timing chain with timing chain tensioner.
The intake air duct and air filter housing have also been modified. The crank drive has been adapted to the higher engine torque.
A Bosch common rail fuel injection system is used.
In addition, engine management components have been modified or added.
Technical data and specifications
Cross-mounted 4-cylinder turbodiesel engine with two overhead camshafts and 16 valves.
Light metal cylinder block with cylinder liners made of cast iron.
Cross flow cylinder head made of aluminium with two overhead camshafts and four valves per cylinder.
Intake camshaft driven via a timing belt
Valves actuated by roller cam followers with hydraulic clearance adjustment
Turbocharger with variable turbine geometry and intercooler
Power output via a dual mass flywheel
Engine management
Direct fuel injection using the common rail method
Solenoid valve controlled injector valve
Fully electronic regulation of fuel metering
Engine emission control
Exhaust Gas Recirculation (EGR)
Oxidation catalytic converter.
European emissions level III
Diagnostics
Diagnosis by means of WDS via the Data Link Connector (DLC)
Torque and power output
The torque delivery curve has been particularly well harmonised as a result of optimised fuel induction and combustion.
At an engine speed as low as 1750 rev/min there is already a torque of 240 Nm available.
The engine delivers a maximum power of 81 kW (110 PS) at 4000 rev/min.
1.8L Duratec HE (MI4) engine
General
Design details of the familiar 1.8L Duratec HE (M14) engine from the Mondeo have been revised.
It is now equipped with an intake manifold switchover system with swirl valves and an ignition system with direct ignition coils.
In addition, an electric throttle valve is also used.
The Air Conditioning (A/C) compressor is located underneath the engine, and the alternator is attached to the cylinder block underneath the intake manifold (in front of the engine when looking towards the front of the vehicle).
The accessory drive system has been revised and now has an additional elastic multi-groove belt which drives the A/C compressor and does not have a separate belt tensioner.

Torque and power output
By using an intake manifold switchover system with swirl valves, it has been possible to increase torque across the entire engine speed range, and at the same time reduce fuel consumption.
The maximum torque of 172 Nm is achieved at an engine speed of 4000 rev/min.
The engine delivers a maximum power of 88 kW (120 PS) at 6000 rev/min.
