SCR System AdBlue Resistance Magnet

SCR is short for Selective Catalytic Reduction, and SCR is a type of active emission control system for diesel powered car. Automotive-grade urea is often served as reductant source, otherwise known as DEF (Diesel Exhaust Fluid) or AdBlue. The reductant agent will be injected into the exhaust stream of the engine, then convert nitrogen oxide into nitrogen, water vapor and carbon dioxide through the chemical reaction, hence discharged through vehicle tailpipe. According to the EPA emissions standards, all heavy-duty diesel truck engines should reduce particulate matter and nitrogen oxides to near zero level.

Adblue has already became consumables of SCR System nowadays. Components of Adblue are urea (32.5%) and demineralized water (67.5%). The concentration of urea has a big influence on the reduction rate of nitrogen oxide and crystallization point of the urea solution. The improper concentration is not only can’t improve the transformation efficiency, but also causes residual ammonia, thus lead to the secondary pollution.

Magnetic design of Adblue Refilling System

The in-built warning sensor will alert the driver when the AdBlue level is low, and actually, there should not be much need to top up too often. AdBlue should be poured in by professional filler nozzle, and how to avoid the miss-filling of Adblue must take into consideration during the early design stage of the whole SCR System.

The introduction of magnetic design is a wise choice for SCR System, and ISO 22241-4 detailed describes the working principle of magnetic design. There is a magnetic switch on the nozzle, which will only be opened under the magnetic field of magnetic adaptor on the filling point. Then Adblue will be allowed into the talk. Therefore, miss-filling into the diesel tank is made impossible.

About AdBlue resistant magnet

As urea solution, the AdBlue is alkaline. The steel, cast iron, cast aluminum and solder will be corroded by AdBlue, and relevant corrosion material will affect the normal operation of SCR System. This is exactly why designers apply magnetic design in SRC System. The magnet also has risks to be corroded under the alkaline conditions, and HSMAG Team has developed AdBlue resistance magnet for filling system under this background.
