This facility is used to measure the exhaust emissions, particulate matter, fuel consumption, and other data of a heavy-duty vehicle by subjecting it to actual driving conditions. We are conducting tests to survey NOx and particulate matter generated by heavy-duty diesel trucks while they are actually running, tests to evaluate the utility and durability of diesel particulate filters (DPF), and tests to evaluate the low pollution performance of next-generation low-pollution heavy-duty trucks (DME trucks, natural gas trucks, hybrid trucks, etc.).
