Method and system for freeze protecting liquid NOx reductants for vehicle application |
摘要 |
A method and system for freeze protecting liquid NOx reductants, preferably used in vehicle applications, wherein a liquid NOx reductant, carried onboard a vehicle exposed to cold weather conditions, is heated by existing thermal energy generated by fuel compression. The heated fuel heats a potentially frozen reductant and the liquid reductant is supplied to an exhaust gas pipe in front of a catalyst for reducing NOx on the surface of the catalyst and catalytically converted into environmentally safe nitrogen and water.
