In addition, the corresponding KBA certifications also exist for the liquid-cooled Hatz H-Series motors 3H50TICD and 4H50TICD in the power classes from 19 to 55 kilowatts.
For the environment: State-of-the-art technology in the Hatz H-series
The Hatz H-series engines are a consistent new development based on the downsizing principle. Selected materials, combined with components such as turbochargers or the Bosch common rail system (off-highway version), come together to form one of the industry's most modern powerhouses with low displacement. To meet the requirements of EU Stage V, the three- and four-cylinder engines are also equipped with a separable – and therefore very maintenance-friendly – combination of diesel oxidation catalytic converter and diesel particulate filter (DOC/DPF).
With optiHEAT (optimised Hatz Exhaust Aftertreatment Technology), the Hatz engineers ensured the best possible design of the DPF in terms of size, optimum adaptation to the possible load profiles in use and a regeneration strategy in line with requirements. In addition, combustion is perfected with iHACS (intelligent Hatz Advanced Combustion Strategy). iHACS ensures extremely low soot input from combustion as well as very low oil consumption and significantly reduced ash input into the filter. The result is a long filter service life with a comparatively small size. Hatz achieved another industry-wide innovation with diesel article filter regeneration. For the first time, an automatic cylinder deactivation during standstill regeneration was integrated in industrial diesel engines.
