Kunming Yunnei Power Co., Ltd. was established in 1999 as a publicly listed company initiated solely by Yunnan Internal Combustion Engine Factory through a social fundraising approach, with over 60 years of history in the research, development, and production of internal combustion engines. Currently, the company has an annual production capacity of 900,000 diesel engines.

The company's DEV series automotive diesel engines adopt advanced international technologies, achieving leading domestic levels in power density and torque density. These engines meet National VI emission standards and are suitable for light trucks, medium trucks, light buses, pickups, passenger cars, dump trucks, and heavy trucks, effectively meeting diverse requirements for power, fuel economy, environmental compliance, and comfort. The YN and DEF series non-road diesel engines comply with China's Stage IV emission standards. The YN classic power series is designed for economical models, while the DEF high-end power series targets mid-to-high-end models, featuring strong power, low fuel consumption, low noise, and high reliability. These are primarily used in construction machinery, agricultural equipment, and fixed power units such as forklifts, tractors, harvesting machinery, loaders, and stationary gensets. The company's G-series gasoline engines and G20 gasoline/natural gas dual-fuel engines offer low fuel consumption and low costs, mainly matching micro trucks, light trucks, and pickups.

The company's products are integrated into best-selling models of major domestic automotive and non-road vehicle manufacturers, securing a leading market position. Additionally, its products are exported with vehicles or machinery to over 40 countries and regions, including Eastern Europe, South America, Africa, and Southeast Asia.

In the new energy sector, guided by the "dual carbon" strategy, the company is accelerating the development of a balanced product strategy that combines traditional and new energy power solutions. It is intensifying efforts in the development and promotion of hybrid, range-extended, dual-fuel, and hydrogen fuel cell products, striving to achieve a breakthrough in its strategic transformation.
