The new modular TDI generation provides a harmonised basis for The modular design principle has been applied both to the core future diesel engines. It comprises four cylinder engines with assemblies basic engine assembly, cylinder head and valvegear displacements from 1.6 l to 2.0 l and power outputs from 66 kW and to the attachments close coupled exhaust gas treatment to 135 kW in the various exhaust emission versions. system and intake manifold with integrated charge air cooler . Audi’s engine development engineers have translated this strategy to the Modular Diesel Platform MDP in order that successive The Modular Diesel Platform MDP will platforms in the mid range, compact and subcompact classes can be supplied with identical or adapted engine assembly modules in meet future exhaust emission regulations, future. reduce CO emissions still further, 2 This will allow for standardised procedures during the develop cater to EU and NAR markets by providing an identical basic ment process and at production facilities within the Group, whilst concept and also ensuring an economical fl ow of materials. eliminate the need for universal use of SCR selective catalytic reduction and accompanying engineering work in vehicle platforms. 608 001 Learning objectives of this Self Study Programme How are the balancer shafts driven What is the function of the exhaust fl ap in the exhaust system This self study programme describes the design and function of What is the term used to describe the cooling system at cold start the 1.6l/2.0l 4 cylinder TDI engine MDP  Modular Diesel Plat What distinguishes the cylinder block of the 1.6l TDI from that of form .
