This Hydrogen Engine From Kia And Hyundai Heralds A New Dawn In Automotive – Everything Will Change – Lagrada

The title of this post, is the same as that of this article on Hydrogen Central.

These are the first two paragraphs.

Hyundai and Kia recently unveiled in Korea a zero-emission hydrogen engine that could disrupt the EV market. Both automakers are at the forefront of the development of hydrogen technology, focusing on both fuel cell systems and investigating the possibilities of sophisticated hydrogen engines.

The future of sustainable mobility is being shaped by Hyundai and Kia’s continuous research and dedication to hydrogen as a clean transportation solution. An increasing number of manufacturers are developing hydrogen engines as an alternative to electric cars and vehicles that use polluting combustion engines.

These three paragraphs outline more details of the engine.

What’s more remarkable about this new hydrogen engine presented in Korea is that it solves all the problems of durability and large-scale viability that hydrogen engines have presented until now.

The project team successfully ensured that the Hyundai-Kia hydrogen engine, designed to burn hydrogen, could sustain high thermal efficiency throughout its operation by infusing hydrogen into the combustion chamber at a pressure of 30 bar.

Although the device’s performance was enhanced by the use of a turbocharger, it was found that the enhanced performance and lower pollution emissions of this kind of “direct injection” eliminated the problems that most automakers have with hydrogen engines. As the emissions of carbon dioxide and fine particles were reduced by 99% and 90%, the Hyundai-Kia hydrogen engine would be considered to have zero emissions.

Thirty years ago, I was involved with a company called DMW.

• The company’s first product was an aerosol valve, that instead of using CFCs or HCFCs as a propellent used nitrogen. The patent was sold to Johnson and Johnson, after being shown during the discussions, that led to the Montreal Protocol and the phase out of CFCs.
• This led to a deal with Glaxo to investigate if DMW’s technology could be used in a metred-dose-inhaler for asthma drugs.
• The successful idea was eventual sold to Boehringer Ingelheim and is now marketed as Respimat.

I can compare the Hyundai-Kia hydrogen injector and the Respimat inhaler

• Hyundai-Kia appear to be using a high pressure of 30 bar to sustain high-thermal efficiency.
• I know that the Respimat inhaler  uses high pressure to obtain a fine mist of the drug.

It sounds to me, that both companies are using the same properties of applying high pressure to a small hole, to disperse one fluid in another.
