In the last issue of《Dimensional classroom》Medium，Xiaowei took you to know Fogler. ECOPLUS Introduction to fault alarm and emergency operation of energy-saving and emission-reduction packaged transfer case clutch。Current period《Dimensional classroom》Xiaowei will take you to learn.Wittgen W 100 HRi/W 130 HRi Introduction of Engine Exhaust Aftertreatment System of One-meter Milling Machine and Related Operation。

W 100 HRi/W 130 HRi The engine of the rear discharge one-meter milling machine adopts Cummins which meets the fourth national emission standard. B6.7 Engine，Rated power 162 kW。The two one-meter milling machines use an integrated exhaust after-treatment system.，Different from half-meter milling machine，Xcept diesel oxidation catalyst DOC、Diesel particulate filter DPF、A selective catalytic reduction device is also added. SCR，In addition to the integrated aftertreatment system，A urea tank and a urea pump are additionally arranged.。

The same as Wittgen's other four devices.，W 100 HRi/W 130 HRi Function switches and alarm icons related to the after-treatment system are added.，The function of the post-processing system can be intuitively prompted.。The same，When the equipment enters the flammable and explosive area，The inhibit regeneration switch needs to be turned on， Prohibition DPF Carry out active regeneration，Avoidance of explosion hazard due to high exhaust temperatures from active regeneration，Turn off the inhibit regeneration switch after the equipment leaves。Click on the video to learn more about Wittgen W 100 HRi/W 130 HRi Relevant knowledge of after-treatment system of milling machine engine！

《Dimensional classroom》It is a video column produced by Wittgen China Technology and Training Center to introduce equipment operation and precautions.，Launch on a regular basis，I hope you will continue to pay attention.。In addition，If you have any questions you want to know, you can also send us a bullet screen or leave a message.。
