DEUTZ said it has received a certificate for the EU Stage-V emission directive for mobile machinery, making it the first engine manufacturer globally to receive the certificate, which will apply from 2019. On September 6, the German Federal Motor Transport Authority formally certified the DEUTZ TTCD 6.1 engine for Stage V, the company said in a press release.
In 2015, DEUTZ had announced that the current engine generation would meet the expected Stage V standard and introduced the ‘Stage V ready’ seal. The entire range of DEUTZ TCD engines fitted with diesel particulate filters now bears this seal. ‘Stage V ready’ has 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.
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 has been employing DPF technology for more than 10 years and it is a standard integral feature of its TCD product range. Changing from the current EU Stage IV to Stage V requires no additional installation space, thus avoiding expensive modifications to customers’ equipment.
Operating a DPF demands in-depth know-how. The load profiles are completely different depending on the equipment in which the engine is installed. An intelligent ‘Heat Management’ system is needed in order to be able to burn off the particles collected in the DPF. DEUTZ has consequently developed what it calls a ‘Heat Mode’ to specifically raise the exhaust-gas temperature and to ensure the machinery is operated safely.
