The new modular TDI generation provides a harmonised basis for future diesel engines. It comprises four cylinder engines with displacements from 1.6 l to 2.0 l and power outputs from 66 kW to 135 kW in the various exhaust emission versions.

Audi’s engine development engineers have translated this strategy to the Modular Diesel Platform (MDP) in order that successive platforms in the mid-range, compact and subcompact classes can be supplied with identical or adapted engine assembly modules in
future.

This will allow for standardised procedures during the development process and at production facilities within the Group, whilst also ensuring an economical fl ow of materials.

The modular design principle has been applied both to the core assemblies (basic engine assembly, cylinder head and valvegear) and to the attachments (close-coupled exhaust gas treatment system and intake manifold with integrated charge air cooler).

The Modular Diesel Platform (MDP) will:

  • meet future exhaust emission regulations,
  • reduce CO2 emissions still further,
  • cater to EU and NAR markets by providing an identical basic concept and
  • eliminate the need for universal use of SCR (selective catalytic reduction) and accompanying engineering work in vehicle platforms.

Learning objectives of this Self Study Programme:

This self study programme describes the design and function of the 1.6l/2.0l 4-cylinder TDI engine (MDP – Modular Diesel Platform). After you have worked your way through this Self Study

Programme, you will be able to answer the following questions:

  • How are the balancer shafts driven?
  • What is the function of the exhaust flap in the exhaust system?
  • What is the term used to describe the cooling system at cold start?
  • What distinguishes the cylinder block of the 1.6l TDI from that of the 2.0l TDI engine?
  • In what order are the cylinder head valves fitted?
