The EA288 engine family is based on the EA189 engine family.[3] EA288 diesel shares displacement, bore pitch, stroke and bore ratio with the EA189 and the new EA211 gasoline engines.[4] It is a family of 3-cylinder and 4-cylinder diesel engines featuring modular diesel engine system (MDB (Modularer Diesel Motor Baukasten)),[5][6][7] 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 after treatment 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.[8][9]
The engine's displacements were 1.4 litres (3 cylinders), 1.6 litres (4 cylinders) and 2.0 litres (4 cylinders),[10][11] with power output between 66 and 176kW.[12]

This is a naturally aspirated (non-turbo) indirect injection version of the 1.9 SDI VE37
Essentially, this ubiquitous engine has the same bottom end (cylinder block/crankcase, crankshaft) as the earlier 1.9 R4 TDI which uses a VP37 VerteilerPumpe distributor injection pump. However, a new cylinder head is fitted to this "PD" engine, to accommodate "Pumpe Düse" Unit Injectors.

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.

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 2010. The engines are produced by Audi Hungaria Zrt. in Győr .
The Gen3 variant increases engine power up to 286PS (210kW; 282bhp) on Audi Q5.[23]
This common rail V6 turbodiesel was developed by Audi, and first installed in the Audi D3 A8 in 2004. Subsequently, made available for all longitudinal engined Audis, along with the same engine orientation in Volkswagen Passenger Cars 'premium' models and Volkswagen Marine applications. Also related to VW's diesel emissions scandal.[24]
