The company is owned by the Chinese company Superior Aviation Beijing, which is 60% owned by Chairman Cheng Shenzong and 40% owned by Beijing E-Town, an economic development agency of the municipal government of Beijing.
The engine is a four-cylinder four-stroke, horizontally-opposed, 3820NaN0 displacement, fuel injected air-cooled, direct-drive, gasoline engine design. It produces 2000NaN0, with an 8.9:1 compression ratio.[2]
The engine is not type certified and is therefore intended for homebuilt aircraft.[3]
In March 2019 the engine type was withdrawn from service and all customer engines were subject to a mandatory, immediate buy-back by the manufacturer to remove them from service. The company made this decision based on detonation problems found in some XP-400 engines that could not be resolved. Due to parts commonality, the decision was made to buy-back the XP-382 engines as well.[4] [5]
