Most agricultural work vehicles, such as tractors, are provided with driving and working power through a diesel engine.

The diesel engine is a reciprocating internal combustion engine that operates by ignition of light or heavy oil as fuel and ignition, and has a high durability but has a serious effect on air pollution compared to gasoline engines (NOx). ) And particulate matter (PM) emissions are severe.

Therefore, countries are tightening regulations on exhaust gas of diesel engines, and technically delay fuel injection timing, reduce exhaust gas concentration by using exhaust gas recirculation device, and improve combustion performance of engine to reduce particulate matter. Various measures such as improvement are being taken.

In particular, the post-treatment technology includes an oxidation catalyst for purifying high boiling point hydrocarbons in particulate matter (PM), a DeNOx catalyst for decomposing or reducing nitrogen oxides (NOx) in an excess oxygen atmosphere, and a diesel filter for filtering particulate matter (PM). Particulate filter (soot) filtration filter (DPF) and the like.

Among these, the diesel particulate filter (DPF) is a technology that collects particulate matter discharged from a diesel engine with a filter, burns it (recycles), and collects particulate matter and continues to use it. In terms of performance, it is known as a very good aftertreatment device.
