The design concept and core technology of Yunnei DEV series engines originate from Germany,s FEV Company. In 2002, Yunnei Power, the largest domestic manufacturer of multi-cylinder small-bore diesel engines, collaborated with FEV, one of the world,s top three authoritative internal combustion engine R&D institutions, to develop electronically controlled high-pressure common rail diesel engines meeting Euro IV, Euro V, and Euro VI standards, using the cutting-edge international advanced diesel technologies. As a result, the DEV power brand was born with great momentum. The DEV series engines adopt modern electronic control and high-pressure common rail technology to further enhance power performance and precisely balance the relations among power, fuel consumption, and noise control. This marks a perfect leap in diesel engine performance and represents advanced diesel engines in China. Currently, the DEV series engines cover displacements from 1.0 to 13.0L, power outputs from 18 to 390kW, and torques from 70 to 2550N·m, including models such as D10, D19, D20, D25, D30, D36, D40, D43, D45, D47, D65, D67, D90, and D130. The full DEV engine series can be perfectly matched with various vehicle types such as micro trucks, light trucks, medium trucks, heavy trucks, pickups, special vehicles, engineering vehicles, dump trucks, SUVs, MPVs, passenger cars, etc., comprehensively meeting the diversified needs of all models in terms of power, economy, reliability, environmental protection, and comfort.
The YN series is a classic product line of Yunnei Power, covering multiple fuel types including diesel and natural gas. It is extensively suitable for applications such as light-duty trucks, medium-duty trucks, light buses, special-purpose vehicles, and construction vehicles. The products comply with China National Emission Standards from Stage I to Stage VI. With a large market base, the YN series is known for its durability and reliability. In addition to diesel engine models, the YN series also includes natural gas engines, such as YN30NF and YN45NF.
