Deutz engine first to get Stage V certificate

German specialist’s TTCD 6.1 engine achieves compliance with regulations due to come into force in 2019


German engine specialist Deutz has become the first manufacturer in the world to claim the EU Stage V emissions regulations certificate for mobile machinery.

The German Federal Motor Transport Authority formally certified the Deutz TTCD 6.1 engine earlier this month for Stage V, the new rules for which will come into force from 2019.

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 by certification of the TCD 3.6, 4.1, 6.1, 7.8 and TTCD 7.8 models.

Deutz said that by obtaining the first EU Stage V certificate, it was also delivering on its environmental promise and positioning itself as an engine manufacturer with an eco-friendly focus.

The EU Stage V emissions standard represented a major challenge to engine manufacturers, said he company, due to the reason that the recently introduced limit on the number of particles can only be met by fitting a diesel particulate filter (DPF).

Deutz said it has been using DPF technology for more than a decade and has made it a standard 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, the company added.

Operating a DPF demands thorough knowledge as 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 added that it has developed a ‘Heat Mode’ specifically to raise the exhaust-gas temperature and to ensure the machinery is operated safely.
