NOx and PM emissions for GYMCL’s YC6L-60 are 307.3 and 6.5 mg/kW·h, respectively—below the Euro VI emissions standards of 0.4 and 0.01 g/kW·h, respectively, for heavy-duty diesel engines.

Guangxi Yuchai Machinery Co. Ltd. (GYMCL), the main operating subsidiary of China Yuchai International Ltd., claims to have recently introduced China’s first prototype diesel engine compliant with Euro VI emissions standards. At GYMCL’s offices in Yulin City, Guangxi Province, the National Passenger Car Quality Supervision and Inspection Center (Tianjin Automotive Test Center) released test results indicating that the NOx and particulate matter emissions of the heavy-duty model YC6L-60 engine were “well below” Euro VI requirements. The diesel engine, which was jointly developed over a four-year period between GYMCL and researchers from Tianjin University’s National Key Laboratory of engine combustion, features a proprietary low-temperature combustion technology that reduces the fuel-injection pressure requirement, medium-intensity cooled exhaust gas recirculation, and selective catalytic reduction technology combined with diesel particulate filter regeneration capability. A timetable has not yet been announced for production of the engine, according to a company spokesman.
