The first certificate in the world under the EU Stage V emissions regulations for mobile machinery is being claimed by German-based engine manufacturer Deutz, with the new rules coming into force from 2019.
On 6 September, 2017, the German Federal Motor Transport Authority formally certified the Deutz TTCD 6.1 engine for Stage V.
In 2015, Deutz said that the current engine generation would meet the expected Stage V standard. It introduced the “Stage V ready” seal, and the entire range of Deutz TCD engines fitted with diesel particulate filters now carries this seal.
Deutz said that “Stage V ready” had now become “Stage V certified”. Initial certification of the TTCD 6.1 is to be followed in November 2017 by certification of the TCD 3.6, 4.1, 6.1, 7.8 and TTCD 7.8 models.
By obtaining the first EU Stage V certificate, Deutz said it was also delivering on its environmental promise and positioning itself as an engine manufacturer with an eco-friendly focus.
The company said the EU Stage V emissions standard represented a major challenge to engine manufacturers, mainly because of the recently introduced limit on the number of particles can only be met by fitting a diesel particulate filter (DPF).
Deutz has been using DPF technology for more than 10 years and it is described as a standard integral feature of its TCD product range. Changing from the current EU Stage IV to Stage V requires no additional installation space, therefore avoiding expensive modifications to customers’ equipment, it said.
Operating a DPF demands in-depth know-how, Deutz added. The load profiles are completely different depending on the equipment in which the engine is installed, and an intelligent heat management system is needed in order to be able to burn off the particles collected in the DPF. Deutz has developed what it calls a Heat Mode specifically to raise the exhaust-gas temperature and to ensure the machinery is operated safely.
