First generation Hyundai R diesel engines

At the very end of 2008, a presentation of a new series of diesel power units developed at the Hyundai-Kia European Research and Development Center in Rüsselheim took place. These are engines with a cast-iron block, an aluminum 16-valve head with hydraulic compensators, a modern Bosch CP4 common rail fuel system with 1800 bar piezo injectors, a variable geometry turbocharger and an intercooler, as well as a timing chain drive.

In addition to the base 2.0-liter D4HA engine, there were two more 2.2-liter units: D4HB for front / all-wheel drive models and D4HC for rear / all-wheel drive cars. Plus, each of these engines was offered in two versions: High Power or Low Power.

In total, the first line included three diesel engines, but in five different modifications:

In 2020, a new generation of R-series diesels with an aluminum cylinder block was introduced. They also received a completely different fuel system with electromagnetic injectors and a maximum injection pressure of 2200 bar, and instead of a pair of timing chains, a belt appeared here.

The second line includes two diesel power units with a working volume of 2.2 liters at once:
