Ecocat to supply SCR catalysts for YaMZ diesel engines

14 February 2013

Ecocat Oy announced it will be supplying SCR catalysts for heavy-duty Euro IV YaMZ diesel engines manufactured by the Russian GAZ Group. The SCR system delivers a high, 95% NOx conversion efficiency (measured over the ESC/ETC cycles) to enable superior fuel economy.

The vanadia-based SCR catalysts are coated on both ceramic and Ecocat’s own metallic substrates. The urea dosing and control system is provided by Albonair GmbH. Through the combination of a high performance catalyst and the Albonair dosing technology, it has been possible to develop a compact (no other catalytic elements than SCR are required) and cost effective NOx control solution, said Ecocat.

The SCR system—developed in cooperation with a Tier 1 system supplier in Russia—has been certified by YAMZ for their 656/658 Euro IV engine series.

The YaMZ 650 series engines are assembled at a GAZ Group’s plant in the Yaroslavl Region. The engines will be used on commercial vehicles produced by MAZ, KrAZ, UralAZ and GAZ vehicles, intended primarily for the Russian market.
