EA897 or Audi V6 TDI engines

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.

Diesel engines 3.0 TDI

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:

• CLAA (204 hp / 400 Nm);
• CLAB (204 hp / 400 Nm);
• CJMA (204 hp / 400 Nm);
• CDUC (245 hp / 500 Nm);
• CDUD (245 hp / 580 Nm);
• CDTA (250 hp / 550 Nm);
• CKVB (245 hp / 500 Nm);
• CKVC (245 hp / 580 Nm);
• CRCA (245 hp / 550 Nm);
• CTBA (258 hp / 580 Nm);
• CGQB (313 hp / 650 Nm).

In addition to Volkswagen and Audi, such a diesel engine was installed on the Porsche Panamera under the MCR.CC index.

Diesel engines EVO 3.0 TDI

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:

• CKVD (218 hp / 500 Nm);
• CRTC (272 hp / 600 Nm);
• CSWB (218 hp / 500 Nm);
• CTBD (262 hp / 580 Nm);
• CVMD (249 hp / 600 Nm);
• CVUA (320 hp / 650 Nm);
• CVWA (204 hp / 450 Nm);
• CVZA (258 hp / 600 Nm);
• CZVA (218 hp / 400 Nm);
• CZVB (218 hp / 400 Nm);
• CZVE (190 hp / 400 Nm);
• CZVF (190 hp / 500 Nm).

In addition to the Volkswagen and Audi models, such an engine was installed on the Porsche Macan under the MCT.BA index.

Diesel engines EVO-2 3.0 TDI

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:

• DCPC (286 hp / 620 Nm);
• DDVB (286 hp / 620 Nm);
• DDVC (286 hp / 600 Nm);
• DHXA (286 hp / 600 Nm).
