To validate the real-road performance of the Yuchai YCY24145-50 engine, a field operation test was conducted in strict alignment with the actual working conditions of urban public transport in Kuala Lumpur, Malaysia. The test route covers core urban roads in Kuala Lumpur, with a one-way mileage of 20–30 km and a round-trip distance capped at 60 km, fully replicating the daily operational scenarios of local public transport fleets.

The test vehicle is a Xiamen King Long KINGO minibus powered by the Yuchai YCY24145-50 engine, with a rated passenger capacity of 15 seats. It operates at a typical speed range of 40–80 km/h. The test was executed under consistent route, payload, and speed parameters to accurately reflect the engine's real-world performance in daily service.
