The reasons for the high fuel consumption of Jiefang truck may be that the air filter element is blocked, the nozzle is poorly atomized and the engine is old.

Jiefang automobile was successfully trial-produced in Changchun No.1 Automobile Factory on July 3, 1956. Before liberation, there were 130 cars of different brands on the expressways in China, just like the "International Automobile Exhibition", but none of them were made in China. The appearance of Jiefang brand cars ended the history that China could not produce cars.
