The EMU (electric multiple units) engine afterburner, a technology patented by a Beijing-based researcher, is expected to exceed 500 kilometers per hour, according to the State Intellectual Property Office.

The afterburner was developed by Wang Guisheng, a former researcher at the Beijing Power Machinery Institute.

According to sources, the new afterburner is expected to achieve speeds of more than 500 kilometers per hour if more power can be put through the engine afterburner while it is traveling at a relatively high speed (such as 200 to 300 kilometers per hour) on a straight track.

Since this patented technology combines existing railway locomotive (diesel and electric locomotives) technology and turbo jet engine afterburner technology, the doubled power and locomotive integration with independently-owned intellectual property rights were born in China, according to experts from the State Intellectual Property Office.
