Great and insightful. Can i get the slides?

Such a great presentation! And a fascinating subject. I hope to see such linear generators used in vehicles in a few years. It's funny how such gems have 100 views on YT.

Great.

Outstanding lecture delivered by Prof. Thibault Guiberti. Our gratitude goes to KAUST - Combustion Institute Summer School for making the video of the presentation available.

Would it be possible to download the ppt presentation slides?

Great overview. I never did any combustion classes at school. Enjoying learning how different fuels burn in different ways. 1.13 min - when you have the right conditions ammonia burns fine :)

Great talk Dr. Karim. Thanks!

I'm curious. Would fixed-timing ammonia motors help control these issues? Some plug-in hybrid vehicles only use motors to drive generators and feel electricity to the batteries. Under fixed conditions, you could control air-fuel, ignition timing, temp, etc. pretty precisely.

From What I Have Read, Laser Ignition' Projected Into An Optical Diffuser, To Scatter The Laser Beam For Engines To Burn Ammonia With No Pilot Fuel.

H2 powering transport is only promoted by those who are either thermodynamic ignorant or those with vested interests.

Brilliant

Thank you very much Giorno.....

Can it be used for ammonia?

cranking of ammonia to generate hydrogen is not necessary, ammonia can be used as fuel

Engine Speed 600rpm? What kind of joke-test this is? What kind of Engine you see running 600rpm on modern automobile?

Quite interesting! Is it possible to achieve food-grade purities? What about the impurities heavier than CO2? They will also desublimate with CO2 right?. All the best.

best of luck that` a real honorable news for us

awesome lecture clearing the questions about combustion in IC engines

Excuse me? I'm not sure about ammonia combustion engine type is a good IDEA!! Burning NH3 will cause NOx instead, The NOx gasses such as Nitrous oxide can cause more global warming than CO2 300 time and live more than 100 years!! So please examine carefully!!!

the lower temperatures for ignition required by the alcohols - could it be because ot the Oxygen in the mollecule? Excellent lecture, btw - thanks!

Excellent!

Waiting for the 3rd day video

校友❤😊

looking forward to the next seminar

Just the evidence I was looking for..thanks

This is wonderful technology

Is there any work about ammonia use in gas tubine? maybe would fit trucks and busses.

Very helpful seminar

Thanks, very complete and interesting presentation. In the case of the SI it was not mentioned the ignition energy used/spark plug types for the studies and it was not mentioned the impact of using different ignition energy levels. I am assuming automotive ignition controllers and j-type were used for the studies due to the engine size mentioned. It would be very interesting to know the impact of using a powerful ignition controller (for industrial gas engines) with at least 1000mJ output power and different spark plugs technologies on emissions, IMEP, efficiency, Temp other.

NH3 seems much better suited to turbine than piston due to the slow flame front and the potential need for multi-stage combustion

Why doesn't a turbine configuration solve all of ammonia's issues? You can run rich to burn with low NOx emission then a second burn phase lean to consume the fuel. Swirl burners have been shown to keep ammonia flame stable, which solves the flame propagation issue without blending other fuels. Any power deficiency relative to gasoline can be overcome with a high RPM 3x supercharged turboshaft configuration (as in helicopters)

Thank for your uploading and sharing! it is very nice reseraches and result. Thank you once again!🥰

Are you aware of your self-identity or living with misconception? ruclips.net/video/KoBxm0FJY3U/видео.html

Brilliant, thank you

I don't understand this. Is the Ammonia Anhydrous Ammonia? Is it some sort of Gaseous (Non Liquid) compressed Ammonia that is injected? Is it the same as grocery store ammonia, and it's mixed with gasoline?

dummies ammonia powered vehicle have been around for over 30 years.

Very interesting. One point I would like to add though, is that a higher mechanical compression ratio is not what produces the heat in a surface combustion engine(diesel) but cylinder pressure. In other words, you could have a Diesel engine with a supercharger to produce the cyl pressure required to initiate combustion even if the compression ratio was only 16:1. Conversely, you could have a naturally aspirated diesel with a mechanical compression ratio of 22:1 and have the exact same cyl pressure. Pressure also being influenced by camshaft timing. Again, very interesting, I enjoyed it.

We designed several professional research processes such as selecting the topic, writing the research proposal, writing the research paper, building and managing the research teams, and ..., however, we are at the beginning of a revolution that is fundamentally changing research. Introduction to the processes is on vasfetoba.com. Also, you can watch these videos on RUclips: ruclips.net/channel/UC26Aaw8DaLgBM7wzX-1Evjw

Really helpful glad that it got shared !

I want to know how these severe changes will affect the economy. Will prices jump through the roof? Will decarbonization make more poor people who will have nothing but clean air? Are we at least 90% sure that it will stop global warming? Imagine this scenario, millions of poor people cooking on a hot summer's day. Not a pretty picture. Engineers, be careful what kind of world you're creating!

I think Jan refers to the lack of CO2 as we run very lean. What is happening is that the temperature is not sufficient to make CO go to CO2. The blacksmith is always burning at close to stoichiometric conditions or even rich. Then CO to CO2 is limited by the lack of oxygen, not temperature.

I strongly admire this smart professor. All the best for you my favorite professor))))

Really informative thank you

Great lecture! Thanks.

I am about half way through. Excellent stuff, for engineers especially. I think I disagree that when more oxygen is present CO2 cannot be formed. This notion goes directly against centuries of blacksmithing practice of limiting air access to increase concentration of CO at the expense of CO2 to alter C composition of the final product. Perhaps the phenomenon can be explained by decrease in pressure.
