Jason - speaking here with some experience related to this challenge... You question about the use of port injection on the basis of it impacting the volumetric efficiency so much. If you go with direct injection that will increase the volumetric efficiency considerably you then end up just having to reduce the compression ratio even further. Also direct injection of a high pressure gaseous fuel is very challenging with regard to the control of the fuel. Time proportioned direct injectors (mechanical or electrical) rely on a very dense fuel in order to minimize the mechanical movement to achieve the required response time.

Full disclosure: I don't know jack about cars, so take with a huge grain of salt. However, due to my hobbies, I have had to learn a little about how to work with liquified gas fuels, specifically propane. Based on that, my guess is that the 80% fill limitation has to do with two things: safety margin for tank pressure increasing with temperature; and, importantly, maintaining sufficient *liquid* fuel surface area for it to boil into the gaseous state needed to run the engine. Those are the considerations typically described for propane tanks, anyway. :)

It felt like we were on a real revolutionary path away from fossil fuels (remember, EVs weren't really a thing yet at that time). But it was very clear that a lot of R&D would still have to go into it. The H2 tank essentially took away all trunk capacity and made the vehicle quite butt-heavy to handle, which may also have been one of the reasons for the power limitations.

Nothing about it would get away from fossil fuels. You can't drill a well to get hydrogen.

Yes, solar can be used for that but that solar could also be used to replace power made from fossil fuels in other areas. Until we have some source of clean energy for ALL power needs, hydrogen is not the answer. Hydrogen is not an energy source (unless we get fusion figured out), it's a gaseous or liquid battery.

Talking about fuel with super high pressure storage. We have been using CNG and LPG in cars, we also use them a lot in Thailand. CNG = super high pressure, so high that it needs a lot of safety to be able to use it almost safely. CNG makes a lot less power with the same ignition timing, and it wears the valve seats a lot faster than gasoline due to its slower burning rate. The system for both CNG and LPG require the heat exchanger too, we call them regulator/vaporizer. LPG makes almost the same power as gasoline with a good tune, regular drivers won't be able to tell the difference if setup & tuned correctly for the fuel alone (same timing). Good thing about CNG is that it can be used in both gasoline and diesel engines. But the thing is it's super slow to refill the tank, and the pump requires super high pressure to be able to fill the tanks. If they are low on LNG(dense liquid) at the pump, they can't fill you the CNG(compressed). While LPG is a lot faster to refill and makes more power with the same setup. I also use LPG(bi-fuel) in my 2 cars, one with 2AZ-FE engine and one with J35Z2 engine. Saves a lot of money, at least half at worst, up to gasoline price at the moment. And I can tune the thing myself with a piggyback CNG/LPG ECU of my choice. I made 278ps with E20 RON95, and 260ps'ish with LPG with same timing and richer Air:LPG equipvalent mixture ratio compared to Air:E20 equivalent mixture ratio. We have a lot of LPG pumps here, while CNG pumps are decreasing in numbers. While hydrogen has been mentioned occasionally by some manufacturers and also looks interesting, I don't really know a thing about it. Thank you for spending time to explain it all to us.

Thank you, I’d always wondered how they did it.

13:45. That would probably be correct that the tank could only be filled to 80%. LPG tanks can only be filled to 80% to leave enough headspace in the tank so stands to reason that liquid hydrogen would be in the same boat.

Hey Engineering explained. I love these hydrogen-related videos. Keep them comming. I work as an engineer with specialization in hydrogen solutions and wanted to share an insight regarding hydrogen ICE engines. Currently there is some ongoing research happening all over. I happened to have a discussion with one of the researches and he said they have been rebuilding an old gas engine to be optimized for hydrogen operation. They have been able to reach efficiency of 1,1 kg/100km, which is very close to that of a modern FCEV. I asked him if there are some benefits to having a hydrogen ICE vehicle over FCEV, and he stated that basically the biggest upside is that you can use hydrogen that is not as "clean" (thus cheaper) and also that it is important to understand that it can work not only with hydrogen, but with standard gas also. So the hydrogen can basically work as the main fuel, and gas will be the "spare" fuel, or vice versa. Very similarly to how it is done today with gas-CNG ICE cars. This allows for highly optimized system that allows you to mostly drive on hydrogen, but minimizes the anxiety from having limited range. Just felt that you might find this interesting :)

The main problem with oil we pump from the earth is that we can not make more of it, at least not the amount we consume every day in this modern world. There is almost no talk at all about the problems of fule cells and EVs that use way to much rare earth metals, that is a dead end if people think that can replace all our current vehicles.

Given that it is so well insulated refrigerating it might not use too much energy, i cannot imagine that using a fuel cell to power refrigeration would be more energy efficient than just venting the hydrogen though.

Part of my guess was there going with liquid over gaseous was that the tank manufacturing for a 5 bar tank was considerably cheaper over a 700 bar tank, and probably quite a bit less explosive in a massive collision. Although I don't know what I'd like less, being subjected to a 700 bar uncontrolled blast of a tank failure, or splashed with LHYD prior to it detonating.

Since we are talking about alternative fuels, what do you think about LPG conversions? Prins offers systems for DI engines now. Since LPG burns cleaner than gas, would that be beneficial for DI engines to avoid carbon deposits? LPG used to deliver a bit less power and poorer fuel economy, is it still the case with today's systems? From what I understand, LPG has a higher octane rating than pump gas, so maybe newer systems take advantage of that? A video on that would be very interesting! Thanks!

VIDEO SUGGESTION: Changing from an OEM wheel with hardened steel lug nut seat inserts to aftermarket aluminum wheels without hardened steel lug nut seat inserts; How does this effect proper torque value? Especially as the aluminum seats start to gall from the much harder steel lug nuts and become sticky, as they inevitably do, when not lubricated (which "every expert" warns not to do). I wonder if the correct solution may actually be to lube the seat surfaces to prevent the sticking and galling (not lubing the threads), and applying a compensatory torque value due to the lube on the seats.

He said in the video that using DI for Hydrogen allowed for more power than using regular gas. So there is a huge difference between what's possible when using DI instead of port injection of hydrogen in a naturally aspirated engine. It should be the same with LPG. However I'm not certain that is still the case if the engine has a turbo or compressor.

@michaelharrison1093

Жыл бұрын

For gaseous fuels like methane, propane, and bio gas direct injection helps on the basis that the fuel no longer displaces a large proportion of the air going into the engine. If the engine is turbo charged then this is a way of making port injection work as you can simply turn up the boost a little to solve this displacement issue. Hydrogen as a fuel in an ICE is a whole different problem and not just one problem. The auto ignition temperature is lower than any other fuel and so is the flame speed and it will burn with just about any air fuel ratio. Basically Hydrogen just wants to explode and this is not what you want in an ICE. To be a good fuel for an ICE you basically want to find a fuel with all the opposite characteristics that Hydrogen has. I.E., you want a slow burning fuel with a high auto ignition temperature - something like gasoline or diesel fuel.

@@michaelharrison1093 assuming you could solve those problems, what efficiency gain would you get? The implied efficiency from the video is 4kg / 100km, which is way worse than the Mirai fuel cell at 1kg / 100km, would direct injection take a hydrogen ICE up to 3kg / 100km? Of note, 1kg of hydrogen moves a Mirai 100km, but takes 54kWh of electricity to make from renewables. 54kWh of electricity will move an EV 300km.

I wonder if you can use liquid hydrogen to cool air for the turbo instead of using intercoolers. I could see its been beneficial for the cars that aim for the top speed since intercoolers induce a lot of drag. I imagine it would be a small tank along the main gas tank to provide that cooling effect AND you can use it as fuel at the same time

The only thing I dont know is how gas combusts in the presence of hydrogen in the cylinder (it might cause some issues) - and this might be one of the reasons nobody really tried it (or I never hear about it).

And if you rich and want really fast autoban trip (or several fast laps on race track) you fill up with hydrogen right before you go. To make it viable for somewhat expensive but really mass market cars hydrogen should be cheap and available at every gas station and I think it really not a big problem if you run out of hydrogen - car just lose some power. Also more strict emission regulations might make it more viable since you don't need so much horsepower to get to the top speed and you burn some hydrogen in your fuel mix.

Venting is ALWAYS a problem. Hydrogen can spontaneously combust at certain concentrations in normal air. At some point between the vent (100% Hydrogen) and a few meters away (100% air), the mixture will reach a spontaneously combustible mixture. This doesn't happen all the time, obviously, but if we put Hydrogen fueling stations in every city, we will see big explosions. Lots of big explosions. It will happen. Be patient.

Rockets use cryogenic hydrogen too. And it's a nightmare, because hydrogen molecules are very small, and therefore leak through anything. NASA's new big rocket (SLS) had a lot of trouble with these leaks. The industry is moving to methane instead, which almost as good overall, but far easier to handle.

Hydrogen is extremely sustainable. The production can be done wherever there is water, instead of mining metals for batteries across the world & transporting them to a country & manufacturer the batteries there & transporting the batteries to the place where cars are made & cost to recycle the batteries (seldom ever mentioned) & cost of battery replacement before the end of life of the EV. Hydrogen is recycled as part of the natural water cycle, after use, where the batteries will require human intervention to recycle, lest the environment is poisoned. Lead acid batteries are nearly 100% recycled, but even the best Lithium batteries are not recycling anywhere near as well as lead acid, meaning the recycled lithium is just poisoning the water supplies… hydrogen does not have that problem. Hydrogen is far more sustainable.

Perhaps Porsche will have better success with their synthetic fuels. I just hope ICE can live on in some form (at least for sports cars, if nothing else). But huge respect to BMW for trying, impressive engineering nonetheless.
