Yuchai YCD4J22D-90
Source-checked against supplied Yuchai workbook 玉柴动力T2柴油机.xlsx, sheet YCD4J22D: 1500 rpm: rated engine 60 kW, standby engine 66 kW at 1500 rpm; matched genset 常用：50 / 备用：55 kW (model cell D6; rating cells D24, D25, D44). Engine rated power is labelled 额定 in the source, not explicitly ISO prime duty. Catalogue power_kw is the highest listed rated engine output. All calibration variants are retained here; frequency-specific prime/standby/electrical fields remain blank because the workbook does not explicitly specify frequency or ISO prime duty. No emissions certification inferred from workbook title. Production status is unknown. Discontinued is the user-authorized catalogue classification (2026-10-21 import), not manufacturer-confirmed cessation; no production-end year is asserted.
