en.Wedoany.com Reported - China Harbin Dongan Automotive Engine Co., Ltd. (referred to as "Dongan Power", 600178.SH) successfully completed the ignition test of the R10TE dual-rotor supercharged engine on June 17, 2026, at its advanced Powertrain System Research Institute Test and Trial Center in Harbin. This engine was iteratively developed by Dongan Power in collaboration with AVL List GmbH (AVL) based on the single-rotor R05E engine, adopting a 1.0-liter dual-rotor plus supercharging architecture, filling a technological gap in China's high-power rotary engine field.
Founded in 1998 and headquartered in Harbin, Heilongjiang Province, Dongan Power is a listed subsidiary of China South Industries Group Corporation, primarily engaged in the R&D, manufacturing, and sales of automotive engines, transmissions, and powertrain products. It is one of the core enterprises in China's micro-vehicle engine sector. AVL, headquartered in Graz, Austria, is a globally leading independent powertrain engineering service provider, offering engine design, simulation, and testing solutions for the automotive and aviation industries.
According to Dongan Power's disclosure, the R10TE engine delivers an output power exceeding 120 kW at a rated speed of 5500 rpm, with a power-to-weight ratio of over 1.8. The initial design weight of 87 kg was reduced to 69.9 kg through fine optimization. In terms of lightweighting, the team replaced traditional cast iron housings with aluminum alloy and reinforced material strength through processes such as supersonic flame spraying and electroplating alloy materials. Technologically, the engine retains mature features like dual ignition systems and wear-resistant coatings, while innovatively adopting a high compression ratio of 11.5, dual-channel turbocharger, advanced composite material sealing system, and lightweight aluminum alloy housing. Dongan Power has filed over 70 related patents for this technology.
For specific low-altitude flight scenarios, the R10TE employs a dry oil pan, multi-stage oil pump, and mechanical water pump forced cooling structure to ensure stable power output under complex conditions such as hovering and tilting. The R&D team will collaborate with the China Aeronautical Comprehensive Technology Research Institute (301 Institute) to advance independent and random airworthiness certification. According to Dongan Power Deputy General Manager Cao Xianhua, in the low-altitude domain, this engine can extend aircraft range from 250 km to 500-1500 km; in the New Energy Vehicle sector, it can be directly installed in vehicles or used as a detachable "mobile power pack." Currently, Dongan Power's rotary engine platform has engaged in in-depth exchanges with companies such as XPeng HT Aero, Changan Flying Car, DJI, and Harbin Aircraft Industry Group.
The R10TE is expected to enter mass production by 2028. This successful ignition marks a key breakthrough in Dongan Power's low-altitude power business, with its rotary engine product matrix now covering displacements from 0.5 to 1.0 liters and power outputs from 50 kW to 120 kW. This achievement is poised to provide an independently controllable power solution for China's low-altitude economy and new energy vehicle industry.
