what are the fuels uses in HCCI engines?
because it must ignite automatically, it should be highly reactive...
so can it be concluded that ab HCCI is a Conventional Diesel engine that is port-injected and not Direct-injected?

If only we didn’t have have climate alarmist pushing world governments to pass regulations that kill the combustion engine cars.

RCCI........two fuel tanks required for Granny Doris to misfuel....

It'd be interesting if they could use some kind of oxygen enriched fuel that would eliminate the need to use outside air in the combustion process. It has already been proven that higher O2 concentrations increase the efficiency of the DI diesel combustion process.

biggest issue is they cost 40 percent less than electric vehicles...so,they arent going away ever.

COMBUSTION FOR LIFE!

Good Vid Jason, .... So what about something SI, like the Eco-boost engines ?

No old style gas engines here - 2 EVs - Tesla Model S & a Mini Electric. ----- No more climate damaging fossil fuel engines.

I'm like number 13000 :D

Currently, Porsche and other Manufacturers are creating Synthetic Fuels . For Internal Combustion Engines which, Combustion Engines will be around longer.

Just do a double nozzle filler and find a way to get out the left over fuel somewhere and than we maybe can get somewhere

RCCI is the next best compromise. But I think the magic is already premixed fuels at the pump.
The f1 turbo era of the 80s were running special blend of racing fuel that had toluene, benzene, diesel, and regular gas. I think it was the BMW team I read an article on where they said gas mileage increased. They were still spark driven but I think heat charging through a controlled heat exchange could prime the primary fuel injection just as it mixed with dense cool air. The secondary fuel is then added in the cylinder and is ready for sparkless ignition via compression.
But the problem is cold starts... not sure how can that be done reliably before the primary intake fuel injector is heat primed... maybe special heat plugged injectors?

For the future of fuel combustion engines... why not just burn gasoline to create electricity in a small efficient turbine? No pistons and complex timing required.

Jason, great video as always. Would love you to explain 6-stroke engines. Hydrocarbon-steam hybrids and their limitations.

I’d love to see combustion engines around as long; they’re just more fun to work on and drive

The deserted eight undoubtedly deserve because indonesia multivariately match via a inconclusive spaghetti. cooing, drab letter

Simple , future of ICE (Internal combustion engine) is working in stationary condition , on sweet spot of power/torque while turning high-efficiency alternator for charging EV's :)Just like diesel locomotive.. Of course , that will also be thing of the past when we learn to harvest energy of the sun efficiently !

Just so the manufacturers know, I would enthusicastically embrace buying two different fuels to reap the benefits of an RCCI engine.

ICE going to be a range extender in future plug in hybrid electric vehicles & range extended electric vehicles //

Automobile engines do not seem to have future for now. Recently, Audi said they will no longer develop new IC engines, due to Eurocomission pushing on Euro-7 but rather try to improve existing ones - and soon we will see many of this.
However, internal combustion engines have future in airplanes - to the point where we can call it a second birth.
Search for Celera 500L - a future of civil aviation. Already flying 460mph (Some civil jets fly hardly more!).
Also, ships. Huge diesels are not going anywhere.

What about a PCCI with diesel?

I hate elon musk for tesla🤬🤬

15:12
After all of this stuff about ICE engines
Just listen to the last bit ,
Sums it up very well .
Buy a Tesla .
And more torque also and that from zero rpm

Organic contaminants and sulfur in fuel are the primary cause of soot. Eliminate contaminants to eliminate soot.
Synthetic fuels made from CO2 and water have no contaminants.

The reciprocating piston Internal Combustion Engine will continue to be used until it is displaced by another motive force which better meets consumers' needs.
All of the engines discussed are reciprocating piston internal combustion engines.
No External Combustion Engines or engines using rotary, not reciprocating, motion are discussed.

Hardly an examination on the future of ICE.

If you use Hemp oil, you lose the emissions.

LPG and Biogas... ;)
It's the future... for combustion engines... ;)

Thanks for including the little bit about electric cars and their efficiency. Can you make a video more in depth about that?

I just read somewhere that Audi stopped any research on combustion engines, so yeah ... they will switch to electric for the developed world and keep selling the actual technology to the rest of the world.

Engines that work in cold and dont require expensive motors/batteries that fail in cold.

Hi, wouldn’t it be fair when you compare efficiencies between combustion engines and electric engines that you take the total efficiency - on the electric side especially from generation to use?
Kind regards from Germany

RCCI is about a hundred years old and very easy to implement, diesel guys have been doing it just about since diesels were invented simply by fogging some propane into the intake manifold on their diesel engines.

My guess: ultra lean hcci turbocharged free-piston engines. Basically a high efficiency combustion-based eletric generator. Timing isn't as much of a issue there because of the constant load and you can take out the whole unit and put a battery there once it becomes more viable because those engines are small and made with modularity in mind (at least that's the Toyota's approach).

Excellent video! Very well and clearly explained! Bravo

I would put 2 fuels in my car.

Short answer, no they don't.

I have a thought/question which is, at the moment it is said that fuel cells (FC's) run on hydrogen or methane gas (with the use of catalysts), why can't hydrocarbon fuels be gasified (most hydrogen produced at the moment is from steam reforming natural gas and it is said this is a large industrial process, but in the past engines were made to run on TVO (tractor vaporising oil) where the fuel was heated (usually by the exhaust) to make it vaporise, I know it's not the same but it should be possible to gasify gasoline and/or diesel) and treated/catalysed for use in a fuel cell to power a vehicle. If it could be made to work wouldn't that have the advantages of each of the 3 main competing technologies (EV's, FC's, ICE) whilst at the same time managing to overcome the problems associated with each of the technologies (as I see it the problem with ICE is not the hydrocarbon fuel but the combustion process), so with the above in mind my answer to your question would be, the ICE is dead --- long live the hydrocarbon fuel cell.

Hydrogen/HHO supplemented diesel would fit into the RCCI category if I'm not mistaken?
That combination seems to be gaining popularity for generators and even some haulage applications.

If you still read this I would be really interested in knowing if there are any studies about water injection.

Petroleum will never go away! Neither will combustion engines, at least not until they get rid of batteries! With batteries, an electric car is far worse for the environment, not to mention people really dont realize what is actually charging their car comes from the same energy, in one way or another, that fuels my car! You can thank Rockefeller for all the misinformation on natural oil!

If the Texas winter storm power demand spike is any indication, we still aren't close to fully electric cars taking over. Can you imagine the same inadequate power grid saddled with millions upon millions of massive fast chargers?

The oil industry runs the world.

There’s actually a demand for that kind of engine in LPG conversion of diesel engines.
The LPG is a high octane fuel that can be port injected.
The engine needs to inject some amount of diesel to start the ignition.

Combustion engines now seem like Rube Goldberg contraptions compared to electric motors. EV Horsepower to weight advantage, and efficiency due to not having to lose energy with reciprocating losses and friction losses. I always wondered how much energy is lost accelerating/decelerating the pistons vs engine friction losses, i.e. which is greater and what fraction of energy is lost?

if the electrical powered system is better than ICE and hydro carbon fuels - why do humans breath oxygen and exhale CO2? isn't it more efficient for us to throw lightning bolts like Zeus?

@Engineering Explained - you were touting electric cars being efficient than ICE, can you prove it?
suppose we have 1 hectare of land and 1 year of time. we can either a) use it to grow crops and turn into ethanol to power an ICE car. or b) cover the land with solar panels to generate AC power, which then coverts to DC to charge an EV. finally, we compare the ICE car and the EV car, which car will drive a longer distance, based on that 1 hectare-land-year unit? in both cases, the original source of energy is sunlight. so this comparison fairly compares whether ICE or EV makes the most efficient use of sunlight. (difficult to compare when using hydro / nuclear)

achates power made some massive improvement's but seems they aren't working much in the civilian world. currently they are working on powerplants for military equipment. they had an F150 getting almost 40mpg with their 2 stroke engine

Wow, it's almost like you don't know anything about global warming and climate science. You do realise that we need to get to pretty much zero combustion of fossil fuels, do you?
You can't talk about the future of combustion engines without mentioning man-made global warming and its implications. So your video misses the whole point. What you would have to discuss is what will a CO2 neutral energy grid look like and is there a place for combustion engines?
This means that the more important thing is the fuel. It's almost all about discussing the fuel. So what options do we have?
-Hydgrogen made form electrolysis of water (inefficient uses about 5 times more energy per distance compared to EV)
-Liquid e-fuels, same problem in combination with an ICE, but even less efficient than hydrogen
-Biofuels, here we often have EROI problems, the inefficient ICE in combination with the fuel makes it an energy sink
Conclusion:
There's likely no future for the internal combustion engine, except for very rich people and maybe in some exotic niches.
Again the goal is CO2 neutrality and not just less CO2 - that's not enough. You don't seem to get that.

Here in Bulgaria we put a LPG sistem on a disel engine this is something like RCCI you put the LPG (or CNG)in the intake and the result is that you have a good increase of power and a little economy

Why can't gasoline/petrol be used in case of diesel in compression ignition engines, though? Is it because of knock and air-fuel mixture preignition-related issues, along with timing? Let's leave out the lubricating properties of diesel for the fuel pump, injectors and other parts that depend on the fuel itself for getting lubricated while running.

We better do something, the earth warmed faster in 2020 than normal because of less particle pollution from planes, cars and more

I like the opposed piston design. How does it stack up against these options wrt emissions?

Have you ever done a video on multiair tech? It's very interesting.

Dude, awesome information - however, please get out of the bathroom when doing the Audio! Put a towel over your head, and do a take, then listen to how much better it sounds - no slapback echo from dreaded head-in-toilet-bowl sounding audio. Thanks much

What about carbon-neutral fuel? I feel like this is the most promising by a mile.

diesel fuel has 30% more energy than regular gasoline/petrol!

The future is wood gas engines. Prove me wrong.

Perfect explaining combustion engine work.

What about particulate emissions filters? Diesel trucks in Australia and Europe are required to have particulate emissions filters, that use something like AdBlue to essentially act like a particulate cat convertor.

Porsche's efuel sounds interesting

Look into the Ducted Fuel injection (DFI) that is currently being developed to address the soot issue for diesel vehicles. It's projecting up to a 90% reduction in particulate emissions, leaving only the NOx to deal with. It's fairly promising from what I've read.

Electric cars make sense for urban anthills, less so most of the world. I suspect that only subsidies are driving this discussion and without them and the agenda behind them this would all go away. A far better solution might be non-plugin hybrids with smaller efficient gasoline engines, designed with far larger batteries than in the past and engineered to self-charge in place even when not rolling down the road. Users could pick the charging interval whenever they "turn off" the vehicle. Tap for 0, 15, 30, 60 minutes or until charged.

I'm pretty sure if Nissan's variable compression engine comes out, the technology could be used to extend the operating range of an HCCI engine.
Also freevalve will completely change the game.

I think the world is meant to save fuel, not carbon dioxide emissions and when electric cars Spread gasoline and diesel will be a cheap than now and world continue with combustion engine and AC engine

you working in an oil rig while cleaning crude oil from beaches, fixed!

A complete waste of time. Will always be a Rube Goldberg contraption, prone to trouble and inefficiency. And boy, it will be very expensive to maintain. It had its time, now bury it!

Can you do a video on gas turbines?

What about MWI (Micro Wave Ignition) ?

Don’t know what ever happened to the natural gas injection for Diesel engines it seemed to be catching on right before all of the new emissions standards started in 2007
It was working as a dual fuel system only less complex it was basically injecting natural gas in the same way drag racers inject nos but was showing that it was helping diesels run extremely clean yes it would be a pain but is probably better than the DPF and DEF systems that are being used currently

general public people gonna put gas in the diesel and diesel in the gas

Realworld - freevalve and 2s opposed piston
50%+ efficient, clean and indestructible/ durable

Whatever happened to opposed piston engines like Achates?

Could you do a segment on the old three on the tree transmission I grew up with. Yes, I’m old.

How do these options compare to hydrogen engines? Especially in terms of efficiency and emissions

I am revisiting this video, throttle body bodies are being used to control NOx emissions nowadays by starving Oxygen from the combustion with Exhaust Gas Re-circulation as well. But why does DI (Direct Injection) produce so much soot in either Gasoline or Diesel? Is DI less efficient in the mixing of the fuel with air than Port Injection is? What causes soot formation in the combustion process?

So I understand that the future of IC engines is that they don't have a future, especially in an environment where their use is being heavily taxed when the alternative technology is heavily subsidized.

The future of combustion engines? Being generators, for instance as range extenders for electric vehicles. Then they don’t require being able to handle more load they can run at optimal rpm for generating electricity.

So, better to keep driving my Euro4 H6 3.0 NA with more CO2 but less NOX and others carcinogenic microparticles !

What type of Combustion engine has a longer longevity lifespan, a turbo or non-turbo?

Variable compression?

Future of combustion engines.
Flat two engines, located under the trunk's floor, generating energy to power the batteries and the electric motors of the car.

To improve efficiency, how about electrically positively charging the head isolated from the block, and grounding pistons to produce a St Elmos fire type spark within the cylinder. enabling multi centred combustion?

The term "IF" says it all

Isn't Mazda doing HCCI already? WIth Skyactive-X engine?

4:36 "How do we fix the emission part of the problem?"
With a cat. QED.
Engineer for efficiency; clean with a cat. Good 'nuff.

Create incentives or grants to coerce large employers to install solar panels OVER employee parking lots. People with EV's drive to work in the AM, plug their car in to charge through the day. No need to charge at night, which will balance the load on the grid during early to mid evening hours. Solar panels don't develop as much energy on cloudy days, but cloudy days also mean lower energy consumption, due to less energy being used to cool homes and businesses, so the load on the grid in the evening, while higher, won't be as much of a factor.

this wont be the end, were only half way there

I don't think he understands how unstable gasoline is compared to diesel. gasoline will definitely ignite from compression way easier that Diesel

I feel like I'm back in school😁

The Australian fires and the California fires and the home Fireplaces are way worse than today's clean burning engines; time for the Greenpissers to stand aside, i am paying dearly for that bs already.

Hey you've been teaching about IC Engines for quite some time now, And now the Combustion Engines are going to take their last breathes. But How About Building a Combustion Engine in one of your videos, It'll be exciting to learn from you what goes into building an actual engine.

the near future will be synthetic gasoline from renewable energy and pushing EV by step by step till the half of the decade. others are just hopes and propaganda.

Ha ha......all this leads to is your last statement......electric motors are superior to internal combustion engines, but the supply of power for ICE (liquid fuel) is currently more practical that the power (batteries) for EVs. But there is still more room to improve the efficiency of ICE, only it is kinda like the attempts to improve tape based recording/playback systems. Just like the reel to reel, 8-track and cassette died, so too will the ICE reach the end of the road........not tomorrow, but eventually. Although I do wonder if the whiteboard will last until the 22nd century. 🙂🤔😏😮

Fantastic channel, learned so much !

I just want the sound, performance and feeling I get from SI and CI engines

with the RCCI how would you prevent gasoline from self-detonating at the kind of pressure needed for diesel to combust? It doesn't make sense, gasoline can only be compressed up to 10-11 bar, while diesel goes much higher than that. Perhaps swap the two? Premix with diesel and inject gasoline at the top of the stroke?

Basic problem is more than two moving parts. Argument over. Oh yea, natural byproduct of ICE is toxic; i.e. carcinogenic, asphyxiation, poison. The list goes on.

12 cylinders forever!
