To evaluate the real-world performance and reliability of the Yuchai YCK13N natural gas engine, an extended field validation program was carried out on heavy-duty trucks operating in Nigeria. The test vehicle operates between Uyo and Calabar, running predominantly on national highways, which closely reflects the tough daily working conditions of long-haul heavy-duty transportation.
The test model is a Dongfeng Changxing heavy-duty truck fitted exclusively with the Yuchai YCK13N engine. Coupled with a Fast Gear 12-speed transmission, the highly integrated powertrain delivers consistent power output and excellent fuel efficiency during full-load highway operation.
