The 4BT3.9 series diesel engine is an early model developed by Cummins. Later, Cummins established a joint venture in China, Dongfeng Cummins, and the 4BT3.9 was one of the first engines produced by the company.This engine has a displacement of 3.9 liters. Due to its early design, it has lower emission requirements, only meeting Euro II emission standards. It also has lower requirements for fuel quality, which helps reduce operating costs.
With the development of Dongfeng Cummins, more and more Cummins engine parts are being produced locally. The 4BT3.9 engines offered by ANTAIOS are all manufactured in China. We can provide 4BT3.9 engines with power outputs ranging from 80-130hp, covering a wide range of applications. In addition to construction machinery, we also offer Cummins 4BT3.9 replacement services for vacuum pumps, air compressor units, generator sets, and other applications. Our 4BT3.9 engines are all custom-made and undergo standardized bench testing before leaving the factory to ensure they match your specific needs.
