DEUTZ bundles exhaust gas technologies in the product line “EAT – Exhaust After-treatment"

The company DEUTZ AG, one of the world’s largest independent engine manufacturers, will in future be bundling its exhaust gas technology expertise in the product line “EAT – Exhaust After-treatment”. The goal is to promote customer-oriented solutions for the system integration of engine/exhaust technology quickly and efficiently, opening up additional growth opportunities by marketing a variety of EAT modules as well as EAT systems, incl. development and application services.

Responsibility for the product line rests with Wilfried Riemann, 49, who joined the company on 1 January 2009. Riemann has a degree in engineering, and also holds an MBA. He has wide-ranging experience in the strategic establishment and expansion of the system business. Riemann was latterly a holder of general commercial power of attorney at ThyssenKrupp Automotive AG, and worked as a programme manager for ThyssenKrupp Technologies AG. In this capacity he was responsible, inter alia, for bringing together the automotive know-how of various group divisions, as well as for the Innovative Car R&D programme. In his new function Riemann reports directly to Helmut Leube, Chief Executive Officer of DEUTZ AG.

With “DVERT” (DEUTZ Variable Emission Reduction Technology), DEUTZ has at its disposal a set of powerful technologies for reducing CO2, nitrogen oxides and particulates. DVERT makes it possible to realise solutions which are consistent with the principle: “as much technology as necessary – not as much as possible.” The main focus of attention for the implementation of the exhaust gas rating Tier 3 concerned internal engine measures, such as for example four-valve technology, common-rail systems with corresponding controls and exhaust gas recirculation systems. In order to comply with the future, far more stringent Tier 4i/f and EU IV standards, the technology spectrum is currently being extended to include exhaust gas after-treatment components such as catalysts, open and closed particle filters, burners for filter regeneration, SCR systems with urea injection (Adblue®) as well as electronic controls. In order to make the integrated engine/exhaust gas concepts as cost-effective as possible, the solutions for Tier 4 interim and EU III B were realised in such a way that they can serve as the basis for the forthcoming levels Tier 4 final and EU IV.

“In addition to powerful modules, the key to creating efficient solutions which require limited installation space and are maintenance-optimised as well as being cost-effective lies in optimising the complete system. For this reason, we offer solutions tailored to the particular field of application, performance class, installation space or region,” explains Wilfried Riemann.



DEUTZ AG is one of the world's leading independent diesel engine manufacturers. As a full-line specialist, DEUTZ produces a wide range of liquid-cooled and air-cooled engines with power outputs ranging from 10kW to 500kW for various applications. Originally founded as N.A. Otto & Cie. in Cologne, Germany, in 1864, DEUTZ AG is now the world's oldest engine manufacturer.
