List of Volkswagen Group diesel engines. The compression-ignition diesel engines listed below are currently [when?] used by various marques of automobiles and commercial vehicles of the German automotive concern, Volkswagen Group,[1] and also in Volkswagen Marine[2] and Volkswagen Industrial Motor[3] applications. All listed engines operate on the four-stroke cycle, and unless stated otherwise, use a wet sump lubrication system, and are water-cooled.[1]

Three- and four-cylinder EA111 diesels
The EA111 series of internal combustion engines was introduced in the mid-1970s in the Audi 50, and shortly after in the original Volkswagen Polo. It is a series of water-cooled inline three- and inline four-cylinder petrol and Diesel engines, in a variety of displacement sizes. This overhead camshaft engine features a crossflow cylinder head design, and directly driven auxiliary units.[clarification needed] The exhaust side is in driving direction, closest to the front of the vehicle.
EA288
The EA288 engine family is based on the EA189 engine family.[4] EA288 diesel shares displacement, cylinder spacing[when defined as?], stroke and bore ratio with the EA189 and the new EA211 gasoline engines.[5] It is a family of 3-cylinder and 4-cylinder diesel engines featuring modular diesel engine system (MDB (Modularer Dieselmotorbaukasten)),[6][7][8] with dual-loop EGR system, with high pressure EGR and a cooled low-pressure EGR loops; variable valve train (VVT) with a camshaft adjuster, Bosch CRS 2-20 2000 bar common rail injection system, cylinder pressure control, a modular close-coupled aftertreatment system that includes a flow-through catalyst followed by a wall-flow diesel particulate filter (DPF). Euro 6 and US Tier 2 emission compliance is achieved via NOx adsorber-based system for smaller size vehicles or urea-SCR system for larger vehicles. Other features included low-friction bearings for the camshaft and balancer shafts, piston rings that have less pre-tension, a two-stage oil pump with volumetric flow control.[9][10]
The engine's displacement was either 1.6 or 2.0 liters, with power output between 66 and 176kW.[11]
Motor type: EA 189 / All R3 1199 ccm three cylinder engines are derived from the R4 1598 ccm 4 cylinder engine, VW just cut off one 399,5 ccm cylinder.
All R3 1422 ccm three cylinder engines are derived from the R4 1896 ccm 4 cylinder engine, VW just cut off one 474,1 ccm cylinder.

Origins
Motor type: EA 188 / All R4 1968 ccm four cylinder engines are derived from the R5 2461 ccm 5 cylinder Audi- engine, VW just cut off one 492,1 ccm cylinder.
Some models are fitted with a diesel particulate filter. According to Audi (UK) 'TDV' stands for Technology Development Vehicle. TDV denotes that a diesel particulate filter is present on the Audi in question but the vehicle was produced just prior to (or during) the legislation process regarding DPFs. The abbreviation 'DPF' was not yet officially in existence so Audi used the 'TDV' letters to identify the diesel particulate filter.
This Pumpe Düse (PD) TDI engine was introduced to replace the older higher-powered versions of the 1.9 TDI. It is the first four-cylinder 16-valve double overhead camshaft (DOHC) Turbocharged Direct Injection (TDI) engine made by Volkswagen Group.

We may think this engine is similar to the mono version, however this is not the case at all. This new engine is very different from the MTDI - mono TDI - or in other words some crucial parts has been redeveloped from scratch. Without this adjustments the long life time of the engine would be greatly reduced. In the ref. document you can find important elements concerning the changes in composition, thickness of materials, construction, new developed component such as crankhouse, additional parts (electric cooling) etc. By googling "The_New_Four-Cylinder_TDI_Biturbo_Engine_from_Volkswagen" you may learn more.[21]
This 2.5-litre inline five engine (R5), wholly designed and developed by Audi, was the first Turbocharged Direct Injection (TDI) diesel engine in 1989, initially used in the Audi 100. This engine was also used in some Volvo Cars models in the 1990s.
VW EA 897 is a diesel engine series of Volkswagen AG, which was developed by Audi. The series comprises six cylinder - V-engines with 3.0 liter displacement and is used in various vehicles of the Volkswagen Group since of 2010. The engines are produced by Audi Hungaria Zrt. in Győr .
