The Korea Institute of Equipment and Supplies (KIMM) introduced on June 10 {that a} KIMM analysis staff mentioned cooperative efforts with the Ulaanbaatar Metropolis’s public transportation authorities and Mongolian College of Science and Expertise to use KIMM’s particulate matter discount expertise to previous buses in Ulaanbaatar to attain sustainable metropolis improvement.
KIMM has been conducting a expertise improvement undertaking led by Dr. Lee Dae-hoon, head of the Dept. of Plasma Engineering, to cut back vehicle exhaust emissions in Ulaanbaatar since final yr.
In 2019, Mongolia formally requested the Korean authorities to offer assist to scale back particulate matter emission from the automobiles in Ulaanbaatar. Tremendous mud air pollution in Mongolia could be very critical because of the widespread use of low-grade heating gasoline; a scarcity of emission discount applied sciences in energy vegetation and factories; and numerous previous automobiles nonetheless in use. Moreover, it’s tough to use current diesel particulate filter (DPF) applied sciences in Mongolian automobiles because of the excessive sulfur concentrations in gasoline sources and low atmospheric temperatures within the winter.
KIMM has developed the world’s first plasma burner-based diesel particulate filter (DPF) expertise, which captures particulate matter generated in the course of the combustion means of diesel engine earlier than burning and removes it. A temperature of at the least 550°C is required for this elimination course of. As such, when the temperature of exhaust fuel will not be excessive sufficient throughout low-speed driving in downtown areas or in the course of the winter, a diesel oxidation catalyst (DOC), gasoline after-injection from the engine, or separate burners are put in to lift the temperature accordingly.
Particularly, development equipment and different particular automobiles present very low exhaust fuel temperatures. In consequence, when making use of typical burner applied sciences, it was tough to use the DPF itself due to ignition failure or unstable flame ensuing within the era of white smoke. To deal with these points, KIMM has developed a DPF system that may be operated stably, even in particular automobiles, by means of improvements utilizing plasma burner expertise, which improved the ignition and flame stability of the burner.
This expertise has been utilized to particular navy automobiles since 2018, and subject checks have demonstrated its capability to alleviate the inconvenience skilled by troopers on account of extreme particulate matter emission. Since 2021, subject checks of this expertise have been utilized to development machines similar to mixers and dump vehicles, as soon as once more confirming vital reductions within the era of white smoke. The sphere checks in Mongolia would be the first of their sort to be carried out abroad.
The KIMM analysis staff signed on June 8 a memorandum of understanding with the Mongolian College of Science and Expertise (MUST), a associate establishment on this undertaking. By means of this settlement, the 2 events agreed to proceed their cooperative analysis efforts for profitable software of plasma DPF expertise in Ulaanbaatar, Mongolia.
KIMM president Park Sang-jin acknowledged that the large-scale software of KIMM’s personalized emission discount expertise in Mongolia will improve South Korea’s standing as a technologically superior nation and contribute to supporting the enlargement of home firms abroad. He additionally added that, shifting ahead, KIMM hopes to contribute to the advance of worldwide points concerning particulate matter air pollution by additional supplying superior applied sciences to different nations with comparatively poor gasoline high quality and car circumstances.
