Development Exhaust After treatment

Biodiesel is a particularly attractive fuel for agricultural machinery. However, the introduction of new emission standards has made the use of exhaust gas treatment systems in agricultural vehicles essential. The combination of biodiesel and exhaust gas treatment causes problems, because the biodiesel contains traces of inorganic elements. These turn into ash during the combustion process in the engine, which can result in permanent damage to the components of the exhaust gas treatment system. Deutz and ASG have investigated the impact of current grades of biodiesel on the systems in real-life operation.


The substitution of fuels based on mineral oils with biofuels is a method to achieve political goals, considerably reduce CO2emissions and save fossil fuels. The EU Commission is pursuing a specific goal in the transport sector, namely that at least 10 % of the conventional fuels used in Europe should be replaced by fuels from renewable sources by the year 2020. This plan...
