SCR+DPF

Simply put this is the combination of two technologies used in series.

Selective catalytic reduction
Selective catalytic reduction (SCR), a process where a gaseous or liquid reductant (most commonly ammonia or urea) is added to the exhaust gas stream and is absorbed onto a catalyst. The reductant reacts with NOx in the exhaust gas to form H2O (water vapor) and N2 (nitrogen gas). READ MORE...

Diesel Particulate Filters (DPF)
Diesel Particulate filters have been in use on non-road machines since the early 80’s and within the automotive industry since mid 90’s. Diesel engines during combustion of the fuel/air mix produce a variety of particles generically classified as diesel particulate matter due to incomplete combustion. The composition of the particles varies widely dependent upon engine type, age, duty cycle, READ MORE...
