Deutz engine is first to be EU Stage V certified


Deutz has become the first engine manufacturer in the world to be Stage V emissions standard certified after a certificate for the 2019 EU emissions directive for mobile machinery was issued to the company this week by the German Federal Motor Transport Authority for its TTCD 6.1 engine.

Customer promise

The approval comes four years after the Cologne-based engine manufacturer announced to its customers that the current engine generation would meet the requirements for Stage V, introducing the ‘Stage V ready’ seal.

Michael Wellenzohn, member of the board of management, sales/marketing and service, Deutz AG, said, “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.”

Major challenge

The Stage V emissions standard represents a significant challenge to engine manufacturers, mainly because the recently introduced limit on the number of particles can be met only by fitting a diesel particulate filter (DPF) – a technology standard on Deutz TCD engines. Changing from the current EU Stage IV to Stage V requires no additional installation space, thus avoiding expensive modifications to customers’ equipment.

Deutz has developed what a ‘Heat Mode’ to burn off the particles collected in the DPF as it raises the exhaust-gas temperature, ensuring the machinery is operated safely. 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.
