EA839 or Audi V6 TFSI engines
The Audi EA839 family of 6-cylinder V-shaped turbo engines has been produced since 2016 and is installed on especially powerful versions of many popular models of the German concern. These engines are divided into two series: with a single turbine of 3.0 liters and a bi-turbo of 2.9 liters.
EA839 3.0 TFSI engines
In 2016, power units of the EA839 family came to replace the turbo engines of the EA837 series. The changes were evolutionary, here is the same aluminum cylinder block with cast-iron liners, four camshafts rotate by chains and are equipped with phase shifters, there is a proprietary Audi Valvelift System or AVS. The compressor has given way to a Twinscroll turbine, which is located in the collapse of the block.
The unit works on the so-called Miller cycle and uses FSI direct fuel injection. There are not so many modifications yet, but their number is growing, the line is in the expansion stage:
3.0 TFSI 24v (2995 cc, 84.5 x 89 mm), direct injection:
- CZSE (340 hp / 500 Nm) for Audi A8 D5 (4N), Audi Q8 1 (4M);
- DLZA (340 hp / 500 Nm) for Audi A6 C8 (4K), Audi A7 C8 (4K);
- CWGD (354 hp / 500 Nm) for Audi S4 B9 (8W), Audi S5 2 (F5);
- DCBD (340 hp / 500 Nm) for Audi Q7 2 (4M), Audi Q8 1 (4M);
- DCBE (340 hp / 450 Nm) for VW Touareg 3 (CR);
- DWVA (367 hp / 550 Nm) for Audi A6 C9 (4L), Audi S5 3 (FU);
EA839 2.9 TFSI engines
Simultaneously with the usual version of the turbo engine, a charged Biturbo modification appeared. The unit with a smaller piston stroke thanks to a pair of turbines develops up to 450 hp and 600 Nm.
Today the line includes both Audi engines and a whole number of versions for Porsche models, including hybrid ones:
2.9 TFSI 24v (2894 cc, 84.5 x 86 mm), direct injection:
- DECA (450 hp / 600 Nm) for Audi RS4 B9 (8W), Audi RS5 2 (F5);
- DECC (470 hp / 600 Nm) for Audi RS4 B9 (8W), Audi RS5 2 (F5);
- DKMB (450 hp / 600 Nm) for Audi S6 C8 (4K), Audi S7 C8 (4K);
- MCS.ZA (440 hp / 550 Nm) for Porsche Panamera 2 (971);
- MCS.ZB (330 hp / 450 Nm) for Porsche Panamera 2 (971);
- MCS.ZD (353 hp / 500 Nm) for Porsche Panamera 3 (976);
- MDC.AB (440 hp / 550 Nm) for Porsche Cayenne 3 (9YA), Porsche Cayenne 3 Coupe (9YB);
- MDG.RB (380 hp / 520 Nm) for Porsche Macan 1 (95B);
- MDG.RC (440 hp / 550 Nm) for Porsche Macan 1 (95B);
- MDG.PA (330 hp / 450 Nm) for Porsche Panamera 2 (971);
- MDG.PC (440 hp / 450 Nm) for Porsche Panamera 2 (971);
- MDG.PD (353 hp / 500 Nm) for Porsche Panamera 3 (976);
- MDG.PE (304 hp / 450 Nm) for Porsche Panamera 3 (976).
