The Difference Between Gasoline And Hydrogen Engines

This video will look at eight major differences between gasoline and hydrogen fuels used in internal combustion engines. This includes the combustion reaction and byproducts, air fuel ratio, ignition energy, flame velocity, auto-ignition temperature, diffusivity, quenching distance, and density. These properties result in drastic differences between using the two fuels, though both can easily be adopted and used in traditional otto-cycle piston cylinder engines, often with little modification to the existing engine hardware. Are hydrogen engines the future of internal combustion? Let's find out!

14 Minutes of uninterrupted teaching. My high school teachers would be pretty jealous of your efficiency. Thanks!
-
I really like how all the pro's and con's are presented in just the facts. I wish the news was like this.
-
As a car guy I really enjoyed your content. I've been working on internal combustion engines for 40 years, and it was great to get your insight into what the future will bring. Thanks so much
-
I remember looking at this in a Ford research study using cylinder pressure analysis. The study showed very high maximum rates of pressure rises compared to gasoline. We thought that the engine would have to be structurally much more robust to accommodate the pressure loads. This was way back in 2006 or 7 when the study was presented.

10:13 "Thermal event" I love how you describe "fire" at first. Highest geek level achieved..
-
It is nice to get this stuff at least at a basic university level and not dumbed down. As an engineer I find videos like this do a good job of explaining just short a deep dive into high level math. With the objection to that is that it would really limit your audience. This is a good balance between going all the way into it while explaining enough. On the other hand need for the chemistry is a given these days for this level of video. Overall, a really good well balanced job
-
I am not skilled from a chemistry perspective, but this was the best video I've seen that clearly explains the difference without too much technical complexity. Well done. Thank you
-
The way you always integrate the mathematics into the science of your videos makes you one of the few credible sources on the internet. Thank you for that.

White board got bigger after 2 million subs. After 3 million subs will the white board be like those chalk boards are universities that have a rolling ladder?
-
Excellent!!!! The only person that I know that can have 15 pages of text in engineering in a video less than 15 minutes long. Very dense content. With a whiteboard on the background? Priceless....
-
While not the focus of the video, at all, I think that was one of the best explanations of engine knock and its relation to octane that Ive seen around... Most 'car guy' vids manage to present it in either an extremely confusing, or flat out incorrect way. Nicely done!
-
I e been a mechanic 40 years and this is the best tutorial I’ve ever watched. Thanks for posting this 😊
-
I should get some sort of diploma from watching every Engineering Explained videos. 🤣
-
Diffusivity is the word of the day!
-
Do you think metal embrittlement would be an issue with hydrogen? Also, do you think direct injection of pure O2 instead of naturally aspirating could offset some of the downsides of using H in an ICE? (ignoring, momentarily, the risks of putting a pure fuel and pure oxidizer in close proximity to each other..) Finally, great video! 👍
-
Great stuff as always ! I always want to know pro's and cons of alternatives and you do that very well . Thanks !
-
Hydrogen be like "I NEVER KNOCKED ON NOBODY!"
-
I appreciate you the time invested in producing this video, thank you.
-
Thanks man! I've been curious about Hydrogen as fuel for internal combustion engines for a long time and you just answered a boatload of (important) questions I never knew existed.
-
Great video! Very well done and easy to understand. I did get the impression that control of the comparison leaned a bit toward gas and that naturally aspirated engines might not be the best vehicle for comparison also I would like to see an actual real world rundown comparing emissions of gasoline, nitrogen and LP
