Company Introduction

Kunming Yunnei Power Co., Ltd. was established in 1999 as a joint-stock listed company solely initiated by Yunnan Internal Combustion Engine Factory through social fundraising. It has been engaged in diesel engine development and production for more than 60 years. The company is a leading enterprise in China's automotive parts and engine industry, a leading enterprise in China's internal combustion engine industry, the second batch of national innovative pilot enterprises, and the first batch of innovative and high-tech enterprises in Yunnan Province. The company has established research and development testing institutions such as FEV High Altitude Laboratory and NVH Laboratory. The national enterprise technology center of the company has a "five in one" research and development pattern to achieve collaborative development of engine powertrain technology.

The company's leading products are in a leading position in the domestic industry. The DEV series diesel engine, which has independent intellectual property rights and international advanced level, is highly efficient, energy-saving and environmentally friendly. Its emissions have reached the level of China V and China VI, and it has been matched with SUV, MPV and sedan models from multiple domestic commercial vehicle enterprises, including light trucks, medium trucks, heavy trucks, and passenger car enterprises. The YN series non road electronically controlled high-pressure common rail diesel engines produced by the company meet the requirements of the third and fourth stages of non road emissions. The variety is complete and the product range is extensive. Currently, the supporting products mainly include forklifts, tractors, loaders, excavators, rotary tillers, and harvesters. The product is exported to countries and regions such as Eastern Europe, South America, Africa, Australia, Southeast Asia, etc. either as a complete machine or as a whole vehicle. While focusing on traditional internal combustion engine business, the company keeps pace with the development of the times, increases innovation in new energy product technology, actively expands into fields such as hybrid power and hydrogen fuel cell powertrain, and strives to promote enterprise transformation and upgrading, steadily improving market competitiveness.
