Stage V certification for Deutz

German engine manufacturer Deutz claims to be the first engine manufacturer in the world to achieve certification for the EU Stage V emission directive for mobile machinery, which will apply from 2019.

At the beginning of September 2017, the German Federal Motor Transport Authority formally certified the Deutz TTCD 6.1 engine for Stage V. According to Deutz, the certification delivers on the promise it made to its customers in 2015 when it announced its current engine generation would meet the expected Stage V standard and introduced the ‘Stage V ready’ seal across its range.

Certification of the TTCD 6.1 will be followed by certification of Deutz’s TCD 3.6 / 4.1 / 6.1 / 7.8 and TTCD 7.8 models in November 2017, the company said.

According to Deutz, the EU Stage V emissions standard represents a major challenge to engine manufacturers, mainly because the recently introduced limit on the number of particles can only be met by fitting a diesel particulate filter (DPF). Deutz said it has used DPF technology for more than ten years and it is a standard feature in its TCD product range. Changing from the current EU Stage IV to Stage V requires no additional installation space, it said, thus avoiding expensive modifications to customers’ equipment.

Operating a DPF requires in-depth know-how, Deutz stated, as load profiles are completely different depending on the equipment in which the engine is installed. An intelligent ‘heat management’ system is needed to be able to burn off the particles collected in the DPF, Deutz said. As a result, it has developed what it calls a ‘Heat Mode’ to specifically raise the exhaust-gas temperature and to ensure the machinery is operated safely.

As Michael Wellenzohn, member of the Board of Management of Deutz for sales, service and marketing, commented, “We made a promise in 2015 and, now that we’ve been awarded the world’s first certificate, we’ve kept that promise. This will provide our customers with flexibility when installing engines in their machinery and give them planning certainty when changing to Stage V. We are particularly proud to receive the world’s first Stage V certification and it underlines our technological lead in exhaust aftertreatment.”
