China's first medium-speed and high-power ammonia fuel engine successfully ignited​

on November 30. According to CCTV News, on the afternoon of November 30, China’s first medium-speed and high-power ammonia fuel engine developed by CRRC Dalian Company was successfully ignited in Dalian. This medium-speed and high-power ammonia fuel engine It is expected to be used in the country's first ammonia fuel tugboat next year to realize the demonstration application of ammonia fuel engines..

an ammonia fuel engine refers to an engine that uses ammonia as fuel. Ammonia fuel is a green fuel synthesized from green hydrogen. It contains no carbon and is easy to liquefy and store. According to reports, the single-cylinder power of this engine can reach 208kW, and the maximum proportion of ammonia energy can reach 85%. Compared with traditional diesel engines, it can reduce carbon emissions by 80%.

The successful development and smooth ignition of the ammonia-fuel engine marks that China has broken through and mastered the key technology of the ammonia-fuel engine, and realized the coordination of the entire industry chain of ammonia-fuel engine parts, complete machines and application scenarios, which will promote the upgrading of the traditional engine industry..

Sounds like we can harvest new sources of energy from human piss. New law: all state employees must pee in designated septic tanks in order to allow energy companies to harvest and process ammonia for railway locomotives. In fact, the successor to 054B frigate could use this fuel as long as all sailors and officers simply urinate into the designated tanks. Just kidding! New Chinese term of the day: 脑洞大开

Toyota's ammonia fuel engine is Chinese developed by GAC.

Although ammonia fuel might be a pretty poor idea with fewer applications but it just goes to show how much innovation sold by renowned brands are actually done in China by Chinese.

yes. this has been a new trend. foreign companies doing R&D in mainland to produce high tech products.

can you post the link of this news. i would like to read. thanks

Big news for domestically produced civil aviation engines

AECC Shanghai is pursuing mixed ownership reform and will launch an independent IPO in the future. will be listed in Shanghai SE ..

According to the "three-step" overall plan formulated by China Aviation Development Corporation: the first step is to complete the capital increase of the original shareholders; the second step is to introduce strategic investors after completing the employee equity incentive plan; the third step is IPO listing, through capital increase and share expansion and listing. Raise more funds.

According to company, the funds raised this time will be used for the development of key pre-research technologies for next generation machine and self-financed support for national technological transformation projects.

It is reported that China Aviation Development Corporation plans to complete the relevant work of introducing strategic investors in the middle of next year.



the current valuation of China Aviation Development Corporation has exceeded 30 Billion RMB. and total assets were 12.415 Billion RMB, with operating income of 4.202 Billion RMB..

According to the development goals of China Aviation Development Corporation, by 2035, it will basically become a world-class civilian large-bypass-ratio turbofan aero-engine enterprise, and two products will be put into the market to realize the domestic replacement of domestically produced large aircraft engines. At the same time, a research and development system with backbone forward design has been established to form design, manufacturing, assembly, test verification and maintenance and overhaul capabilities, and create a high-quality talent team with international competitiveness and innovation leadership.

Lots of better industry sources but here's a summary

Should be noted that when they say "developed in conjunction with Toyota" they mean Toyota owns some share of GAC. The tech is Chinese and Toyota partially financed the ammonia combustion engine project but do not exclusively own the commercial rights. In any case, owning the knowledge and capability >> commercial rights. GAC i.e. China own the knowledge, capability, and partially own the commercial rights of this not particularly exciting technology but one with "strategic" applications given the nature of the fuel used (very ubiquitous organic waste). Obviously the safety of fuel logistics and use in cars is an issue with NH3 power. Bit of a weird one where the execs at GAC and Toyota even poured money and engineering time into this tech branch. Indeed lots of applications but maybe not great for cars? Then again plenty of Chinese carmakers are developing hydrogen combustion engines... not just H2 fuel cell NEVs which Toyota of course makes a lot of noise about since they're probably most ahead in this field.

You can look at industry sources going into detail on how many shares of GAC Toyota owns. Sort of like how Mercedes Benz is roughly 20% Chinese owned via various groups.

A piece of aerospace history. The excerpt in the image talks about fruitful R&D results in developing carbon fiber composite fan blades and compressor blades, among other parts. According to the original poster, this was from 1978.

A milestone event: on December 8, the first batch of mass-produced WZ-16 turboshafts was delivered to end user (AVIC Harbin).

I remember the hot section (turbine?) is manufactured by Safran?

WZ-16 all components produced in mainland.

its a joint program by AVIC Harbin and ''SafranChina'' for civilian helicopters. 50/50 partnership. all IP rights of WZ-16 are validate within China.

How many units are in the the 1st mass produced batch? 100?
