The V6 series of Audi EA897 3.0 TDI diesel engines has been produced at the Győr plant since 2010 and is still actively installed on almost all major models of the German company. The family is conditionally divided into three generations of engines, the second is called EVO, and the third EVO2.
In 2010, the second generation 3.0 TDI engines debuted on the Audi A8 D4. The new diesel engines were essentially just a big upgrade of their predecessors: the Bosch Common Rail system with piezo injectors was updated, the intake manifold was redesigned, except that the timing has changed seriously and now there are a couple of large chains instead of four small ones.
The basis of the design remained the same: a cast-iron block with a 90-degree camber angle, two aluminum cylinder heads, two camshafts each and 24 valves with hydraulic compensators. The Honeywell GT2256 or GT2260 turbine is responsible for supercharging, depending on the engine version.
The line includes dozens of power units, the most powerful of them with twin turbocharging:
In addition to Volkswagen and Audi, such a diesel engine was installed on the Porsche Panamera under the MCR.CC index.
In 2014, diesel power units of the EA897 family received their first restyling. The main changes were related to the environment, now all versions began to support EURO 6. The timing was revised again, a third chain appeared in front of the engine to drive the oil pump.
The conventional turbine HTT GT 2260 gave way to a variable geometry version of the GTD 2060 VZ, thanks to which it was possible to slightly, but reduce the compression ratio in the engine from 16.8 to 16.
The new line included a fairly large number of units, all with single turbocharging:
In addition to the Volkswagen and Audi models, such an engine was installed on the Porsche Macan under the MCT.BA index.
In 2017, the EA897 family of diesel engines was once again upgraded and again the main changes were related to the environment, now due to the support of Euro 6D.
The engine design was slightly optimized, the cylinder block lost more than a kilogram of weight, a new exhaust gas aftertreatment module appeared, a significantly more compact timing, a different turbocharger with variable geometry and a maximum boost pressure of 3.3 bar.
The latest line of diesels is now in the process of filling and so far there are not so many modifications:
The 3.0-liter Volkswagen CJMA 3.0 TDI engine was produced by the concern from 2010 to 2018 and was installed on the base modification of the Touareg model, as well as the European version of the Q7. This engine is essentially a version of a diesel engine under the CRCA index, derated to 204 hp.
The 3.0-liter Audi CDUC 3.0 TDI diesel engine was assembled by the company from 2010 to 2015 and installed on such popular models of the German concern as the A4 B8, A6 C7 or A7 C7.
The 3.0-liter Audi CDUD 3.0 TDI engine was assembled by the German concern from 2010 to 2014 and installed on a number of popular company models, such as the A6 C7, A7 C7 and the Q5 crossover.
The 3.0-liter Volkswagen CRCA 3.0 TDI diesel engine was produced from 2011 to 2018 and was installed only on the two most popular group crossovers: Touareg NF or Q7 4L. Such a power unit was installed on the Porsche Cayenne and Panamera under the indices MCR.CA and MCR.CC.
The 3.0-liter Audi CRTC 3.0 TDI diesel engine was assembled by the concern from 2015 to 2018 and installed on European modifications of such popular models as the A4, A5 or Q7. This motor belonged to the updated EVO series, which quickly gave way to the EVO-2.
The 3.0-liter Audi CVMD 3.0 TDI diesel engine has been assembled by the concern only since 2015 and is installed on modifications of the Q7, Q8 and Volkswagen Touareg 3 crossovers. Its power is limited to 249 hp especially for some markets.
The 3.0-liter Audi DCPC 3.0 TDI diesel engine has been assembled at the Győr plant since 2017 and is installed only in the Q5 crossover, very popular in the European market. This diesel belongs to the EA897 EVO-2 series and meets the stringent Euro 6d-TEMP emission standards.
