Pure Biodiesel OKed for Deutz Agripower Engines

deutzlogoSome agricultural diesel engines made by German manufacturer Deutz are greenlighted for running on pure biodiesel. In this article from Biodiesel Magazine, testing funded by the German oilseed organization Union zur Förderung von Oel- und Proteinpflanzen (UFOP) shows Deutz Agripower engines of the series TCD 7.8 L6, TCD 6.1 L6 and TCD 4.1 L4 can use B100.

In the course of this project, the engines were subjected to extensive field tests in practice, with a conclusive result for Deutz common rail injection systems and exhaust gas aftertreatment systems…

From the point of view of UFOP, verification for meeting the exhaust stage EU COM IIIB applicable since 2011 with biodiesel as a pure fuel is given upon successful completion of this project. This exhaust stage requires the use of exhaust gas aftertreatment systems. Here, Deutz AG offers around 4 to 8 liters of capacity in agricultural applications for the so-called SCR technique (selective catalytic reduction). The SCR system used operates with a 32.5 percent aqueous urea solution (Adblue), which is injected into the exhaust gas upstream of the catalytic converter with the aim of converting nitrogen oxides into harmless nitrogen.

The study goes on to show that a high quality B100 was very good at lowering particles in exhaust. UFOP added that this only underscores the need to strengthen biodiesel quality standards.
