To reduce our impact on the environment with the emissions of diesel internal combustion engines, in some trucks and cars SCR catalytic converters are installed. In order to work properly these converters need diesel exhaust fluid, standardised as AUS-32 in ISO 22241. Here you will find all pumps, refueling sets, tanks and accessoires for DEF/AdBlue®.
Diesel engines emit, due to their design, NOx. Those nitrogen oxides are relevant for the ozone depletion. In order to reduce these climate damaging emissions, limits were enshrined in laws, which are known in the EU as EURO 5 and EURO 6. To reach the goal of not exceeding the emission limits most of the modern diesel engines are equipped with SCR catalytic converters. Prior to the SCR catalytic converter AUS-32 is injected which reacts with about 90% of the emitted NOx to harmless N2 (Nitrogen), water and little amounts of carbon dioxide.
