| Description and Operation The 2.2L Duratorq-TDCi (DW) diesel engine extends the range of TDCi 4-cylinder turbocharged diesel engines. The engine is a joint development by Ford and the PSA Group (Peugot/Citroën). The engine will initially be used at Ford in the EUCD platform (S-MAX/Galaxy and new Mondeo). Its use in further areas of the vehicle fleet is currently in planning. Features - 4-cylinder turbodiesel in-line engine with two overhead camshafts and 16 valve technology
- Cast iron cylinder block with cast-in cylinder liners
- Ladder frame for extending the cylinder block
- Balance shaft unit for optimum running smoothness
- Two-part cylinder head made from aluminium
- Exhaust camshaft driven by a timing belt
- Intake camshaft driven via a timing chain (driven by the exhaust camshaft)
- Valves actuated by roller cam followers with hydraulic tappets
- Swirl and charge ducts for optimum combustion under all operating conditions
- Variable-geometry turbocharger for optimum cylinder charging
Fuel system - Bosch common rail system with maximum fuel pump pressure of 1600 bar (also up to 1800 bar for a limited time)
- Fuel injectors with piezo technology
- Electric fuel pump for assisting with filling of the swirl pot in the fuel tank
Engine management - Bosch PCM (powertrain control module) EDC16CP39
- Fuel metering valve, fuel pressure regulator and fuel pressure sensor for efficient regulation of the fuel pressure
- Turbocharger variable vane electrical actuator
- Actuator motor-controlled EGR (exhaust gas recirculation) valve
- Actuator motor-controlled intake manifold flap with position sensor
- generator control via LIN data bus system
- Oil temperature sensor as an input variable for calculating the oil quality
Engine-emission control - Meets EURO IV
- Actuator motor-controlled EGR valve
- Intake manifold flap with position sensor
- Broadband Lambda probe for correcting the injection volume and for optimizing the EGR
- Coated DPF (diesel particulate filter) to minimize rust particle emissions
Diagnosis - Via the DLC (data link connector)with IDS (Integrated Diagnostic System)
