The BMW M4 GTS is one of very few production cars to ever be fitted with a water injection system, used to take the twin-turbo I6 engine from 444 Horsepower up to 493 horsepower, using the beauty of evaporating water to do so!
From BMW, here's how it all works:
"Water is injected as a fine spray into the intake manifold plenum chamber where it evaporates, significantly lowering the temperature of the intake air. This reduces the final compression temperature in the combustion chamber, which also reduces the risk of knock, allowing the turbocharged engine to operate with higher boost pressure and earlier spark timing. The result is increased power and torque, and a substantial improvement in efficiency. Despite the extra power output, thermal stress on all performance-related components is reduced. All of these features ultimately help to diminish wear and prolong engine life. The benefits of water injection can be utilised in various ways, depending on engine and vehicle type. In particular the engineers have considerable latitude when deciding how to balance their priorities between increased power and fuel efficiency. If water injection is taken into account in the design of a high-performance engine right from the start, it is possible to use turbochargers with a higher boost ratio and compression ratio.
Water injection provides a particularly effective way of raising the knock threshold in this range, allowing the compression ratio to be increased. This makes it possible to optimise the power output of the turbocharged engine over a wide operating range. The lower the octane rating of the fuel, the greater the potential of this technology. In terms of practical implementation, the BMW M division’s engineers opted for an arrangement whereby three water injectors in the intake plenum chamber each supply water to two of the straight-six engine’s cylinders. This solution makes for uniform water distribution and a compact system design.
On safety grounds, the BMW M water injection system is equipped with a sophisticated self-diagnosis system. If the water tank runs dry, or in the event of a system malfunction, appropriate measures are taken to protect the engine. Boost pressure is reduced and the spark timing is retarded, allowing the engine to continue to operate safely at reduced power. Even when things are working normally, a variety of precautions are taken to keep the system fully functional. Every time the engine is switched off, all the water in the hose system is drained into the tank to prevent system components from icing up in sub-zero temperatures. The water tank is likewise frost-proof."

calee4nyaboy Yes lol. I know. But I was researching this the night before. Then he uploaded this video. There’s a good chance he already made this video and had it planned in advance. So this instance. Not google spying. Coincidence. 😂
Oh Jason, you missed a really important fact: the water will continue to evaporate even more during the exhaust cycle when the cylinder pressure starts decreasing and the temps are still very high. This absorbs a lot of heat from the cylinders so the piston crowns and ringlands will love this gimmick.
I kind of love the fact that the M4GTS came ready for WMI since it has this WI kit already on. So with a tune and some alcohol in the trunk tank you can probably squeeze 100hp more out of it.
...assuming that all the seals and plastics in the water injection system are compatible with methanol.
I wonder how long it'll be before some clown fills the system with tap water and gets limescale in their engine.
Won't the water be fully evaporated by then? Doesn't really matter though when it evaporates, it takes roughly the same amount of energy to evaporate the water, whenever it happens. Thus, the exact moment of evaporation shouldn't influence temperature at the exhaust stroke, as long as all water is evaporated before leaving the cylinder.
I would say, the evaporation of water should be completed before the compression stroke becaise water is incompressible. The cooling of the piston crown and engine block is occur only during the evaporation of the liquid water via the latent heat of vaporization. So, thr is nothing to do with the exhaust cycle.
@@izzyplusplusplus1004 You are right on the effect of water injection on the pressure inlet of the turbine. However, the turbocharger needs higher turbine temperature to improve the output. So, the temperature and pressure needs to balance up to get The most of of the water injection. The benefits of water injection is more substantial at thel medium to high load operation.
@@xmenlingcheehuat0811 The water is sprayed through some atomizing nozzles so there's absolutely no chance of hydrolocking. The evaporation process occurs for those small water droplets, so spraying it though those nozzles help with the evaporation surface increase.
Therefore the water continues to evaporate in the intake manifold where it is sprayed but then when the cylinder pressure increases, even though the temperature increases as well (during the power stroke) you don't have so much evaporation. Yet the injected water is mostly (not totally) inert during combustion and what survives will continue to evaporate due to the high temperature and the decrease in pressure. I think the excess of fuel from rich mixtures does the same, just that the fuel is more unstable in those conditions and will burn partially.
This is such a solid system. I really wish they would incorporate this into more cars. The cost / benefit makes dam good sense.
I think it would be interesting if you did a video on the advantages/disadvantages of air to air and air to water intercoolers. They each serve their roll well.
With my 2001 VW 1.8t, water/meth injection allowed about 5 degrees advanced timing (turbo was already being pushed past its efficiency range). It was about the same as running ~97-100 octane race fuel (93+105 race gas mix). Upgraded from 3L to 5L windshield washer fluid reservoir and it would last quite a while, best part of a shared res, it lets you know when its low on the dash. The controller was set to start injection at 5lbs of boost and max over 10lbs, car was limited to 20lbs. Also had a boost-actuated dump on the exhaust after the cat that opened at 5lbs.
Windshield washer fluid is mostly methanol alcohol so good do well below 0F. This was about 15 years ago, its cool to see this on other cars now but having another maintenance item is a huge turn off to 'most' drivers. It would have been cool if BMW did a combined reservoir but for 'safety' reasons i'm sure you couldn't legally do that; depleting your windshield washer fluid.
It also has the effect of steam cleaning your engine. And to think this stuff dates back 100 years or even more with aircraft!
Ive got a CFS water /air charger in my f89 its aftermarket and twice as big as the stock one. Ive never had any problem with it
Very cool. I like how this was explained. It makes perfect sense. It would be great if more manufacturers started using this type of cooling in their cars.
All this info and no ads, your channel is the best!
*AWESOME* video! I've always wondered about water injection since I played "Combat Flight Simulator" years ago on my old laptop. Thanks for another great video.
It really amazes me that technology that was used almost 100 years ago, gets threw out and then comes back around. In 1923 John Deere started making the Model D tractor, also the longest running production model ever at 30 years made. They ran straight water in the radiators and had a valve that took water from the rad and injected it into the cylinders to stop ping (pre-Ignition). Also these tractors where capable of running on Gas/Diesel/Kerosene/Distillate and pretty much anything else that was flammable, Jason covered this in another video about a engine mixing gad and diesel for more efficiency. Just amazes me what technology invested that long ago comes back around and makes a difference in today's world and technology.
It disappears are comes back because there is much more control over what happens. The original systems you mention were very crude, simple tech that failed all the time, but the theory was good. Now, with computers doing all the control, these theories can be put into practice in a much more predictable way.
M water?! That´s a good one. Good Explanation Jason, Regards from Europe.
Jason, again well done. Really like your teaching style, great subjects too. Thank you.
Very cool! I love the idea of using the refrigerant lines to cool the intake manifold/ head/ or intercooler/ injection system. Seems logical to cool it as much as possible
Just buy Ford RS, their head gaskets leak from factory.

Enjoyed the video as always, love the tech. But a side issue that I would like to know is. Does the water injection in any way help to clean inlet ports from coking up as in regular direct fuel injected engines? Btw, water injection goes way back in motoring history. interesting subject. Ooops I see others have already discussed the subject.
I only use Fiji water in my BMW 😂 *jk, I'm a broke college kid*

Keep it up
Where do you find all these graphics like the BMW with no body on it and the cutaway engine? I've always wondered how RUclips channels get things like that
BMW's media website. Anyone can access it! :)
I wonder if a water/alcohol mix would be even better. Water and alcohol are miscible in all proportions and alcohol has a higher latent heat of evaporation. I am thinking the mix would have even greater cooling properties than pure water. Perhaps 90% water and 10% alcohol.
Would be. No freezing, some extra power etc.
An excellent explanation as always. This technology has been around for years. I think WW2 airplanes used methonal injection. My neighbor was an amazing inventor, engineer&mechanic. He put water injection systems on multiple vehicles including a huge diesel powered fishing trawler. This was mid '50s to about 1975 when he just quit everything else to build dirt track race cars.
Super Nice explaining. I did not Know this. Thanks for god content.
And they also solve the carbon deposits in the engine :p
Not true. Water solves only carbon deposits on top of pistons, inside cylinders and exhaust valves/turbo vanes. Nothing else. And this is only part of engine.
@@Fosgen doesn't it also solve the problem on the intake side? which is where all the carbon buildup happens
@@85CEKR No mate. Water is injected as cool liquid (maybe 20C degrees more than room temperature), and covering anything with slightly warm water, already covered with some dust and oil (typical for intakes of turbo charged engines), won't have any effect at all. Oil is not soluble in water, and oil viscosity is higher than water. Oil and dirt will star on intake side, for long time, unfortunately. Best way to clean it is taking off engine and soda/sodium blasting.
Water injected has it's value when turned into the steam because of temperatures inside combustion chamber. Then some specific reactions occurs:
C + H2O = CO + H2
C + H2O = CO2 + 2H2
These reactions occurs mainly on surface, so cleaning of deposits is not quick but it works and overtime surfaces coated with oil and carbon (sludge) may be completely clean. But it takes time and high temperatures of steam, constantly flowing along dirty surfaces.
@@Fosgen huh, didn't know that water did react with CO2, the free H2 might give it w tiny boost while maybe also diffusing trough the steel and stealing the carbon
@@crackedemerald4930 water is known to increase in volume by 1700 times when turn from liquid into the steam. This can be turned into mechanical energy in combustion chamber as water is squeezed with air before combustion.
And what happens then in the cylinder? How the water influences the combustion/emission?
Since it's evaporated Its just like driving on a humid day, more water in the air but it doesn't play a part in combustion
But still can have an effect, at least it reduces the useful displacement, what may be insignificant, I don't know, that's why I asked. ;)
@@robertkulyassa2084 to a very small degree but we need to remember that that is a replacement for displacement, and that is forced induction. Increasing the boost pressure gets more oxygen into the cylinder regardless of the fact that a tiny amount of the displacement is used up through water vapour.
@@robertkulyassa2084 the overall effect is +49 horsepower
The water can absorb heat, it expand at a good ratio (since its fairly light molecule) and can reduce wasted energy going out of the engine in heat. Fuel, when burned, also create water vapor.
I just watched this guys turbocharger video from 2011 and wow. The growth is really evident.
You are a gift to us. Thank You.,
What is positive side to using mix of methanol and water? Wouldn't pure water corrode inside of intake manifold and engine head? Thanks in advance
I'm fairly sure that the intake manifold and the head are made out of aluminum, so no corrosion
Positive is it helps prevent knock. Thus higher boost/hp levels can be acheived smoothly. It also slightly cools the engine.
Methanol acts as an antifreeze
I don't think that corrosion is a big problem with this, because the water is only used rarely and in high heat situations, so it probably evaporates almost instantly. And water vapour is a byproduct of combustion anyway.
Methanol and water makes more power than water alone, interestingly pure water injection cools the air more than the mixture. Methanol also acts as an antifreeze, this tech was first used in airplanes where the water freezing was more of a concern.
How about utilizing liquid oxygen to cool it.
Rian hot damn, that’s cool.
it took 2 times to understand all of it, because it's water in engine. But you made it extremely good, and informative. Thanks
Amazing amazing stuff, this absolutely intrigued me!!! I want to know where I can learn more? Only if the information being given is explained in the same way you presented it.
What about the tank itself freezing if you park outside in winter? Is it pure water?
@@xenonram He doesn't say what happens to tank itself. Its it heated? It will freeze if left outside.
The tank is probably made if something a little flexible
@@isaackarjala7916 yeah, I guess the same thing as with washer fluid. It can easily freeze, and nothing especially bad will happened with the system.

*NOTIFICATION SQUAD* 😆😆😆
Im surprised it took the auto industry this long to come up with this. After learning a bit about compression ratios, knock prevention and air fuel ratios it was obvious to me that its more logical to use cheap water to drop temperatures instead of just more fuel
Actually implemented in the 60’s in the Oldsmobile Jetfire, though they used a combination of water and methanol.
@@EngineeringExplained dude could this also solve the carbon build up on direct injection engines?
It's been done before but having to check a water tank and filling isn't something most car owners ever want to do. Mist would probably prefer 493hp all the time and lower fuel mileage.
It was also available on 1st gen STi Type-R with manual or automatic water spray, the 90s were a cool time.
the reason you don't see it widely used is because it adds a bunch of components, nozzles, lines that cost money. Not to mention the computer having to adjust according to outside temps. All that stuff adds money and weight for a negliable amount of HP. Pretty useless in most cars simply because they don't have turbos.
Brilliant stuff.
Great vid!
so its basically a meth injection ?
Why use water for +50 hp??? Just use a fake hood vent, every one knows you can get +200 hp with it
I’m glad that we’re finally getting over putting fake hood vents on production cars. Still a couple that do it, but mostly dead.
@@EngineeringExplained But, gotta keep the JDM badges. Good for many hp's, even on German cars!
Thanks. Nice video .
I know its lots of research but its the best content on your channel (im a bmw fanatic) 😀😀😀
Imagine one of those injectors being stuck open. Rips the whole block apart
Marke injectors very rarely stick open and how is a mist of water being sprayed into the intake manifold going to rip the block apart? lol
@@shenaniganshop3309 ever heard of flooding an engine? On (at least slightly) compressible gasoline that's one thing. Water is not compressible. That's going to increase the "compression ratio" drastically
Marke liquid gasoline isn’t compressible either lol and how often do you hear about leaky fuel injectors hydro locking an engine? Not very so I’m sure it will be even less common then a fuel injector leaking since it gets used much less, also the water injectors spray a very fine mist that’s why five liters of water can last a whole 15 gallon tank of gas, they hardly spray any water. Not gonna be a problem.
@@shenaniganshop3309 If you say so dude
Marke instantly thought of rolling my poor 84 LT125 Suzuki ATV in a local pond. It didn't hydro lock luckily. But interesting thought, bet they injectors are engineered to fail in a closed position. Like o2's fail lean,so the ecu interprets and saves us by running rich. Rambling on here......have a good one
But what if you used methanol instead?
it wouldn't be so exciting and "new" to the uninformed consumer hahahaha
Wet shot. I’m not sure how much it would cool the cylinder (alcohol having a lower boiling point), but you’d definitely get an increase in power output. WET SHOT!
Max of 50/50 is safe in a non race vehicle. Methanol by its self burns in a almost invisible flame. Though I don't think BMW will post a rating with any mix of methanol, for safety/legal/warranty reasons.
Edit: to be safe, and cheap. My system I use -20 windshield washer fluid.
Put some quality vodka in there! You have both alcohol and water😂, but I'm afraid it's going to be expensive
Very good topic sir
Finally. Thank you, i was wandering how water injection works in M4 GTS
Does that require distilled water?
Exactly
Of course!
Mountain Dew
The reason I ask is because a system that advanced could have a filtration system with a micron rating that would be sufficient to clean water. Also where I live gas is around 2.20$ per gallon and distilled water is 75 cents to 1$. Does that water really need to be cleaner than the fuel?
@@melaniew77msn it's not about the price, distilling water is a easy and cheap process and it makes water almost pure, and about the filtering the water, maintaince costs of BMWs are already very high, a filter would be something to be changed once in a while, and it would make maintenance higher and make the car less independent, so thank you bmw! This car better off without a filter for that water!
Wow, BMW actually made an engine that might not explode in the first 10,000 miles even if you're driving it hard.
Are modern BMWs really that bad?
I still love my old 92 E36. No vanos, no turbos, no problems. As far as I can tell the M50 engine is pretty bulletproof.
zuilok yes they are bad. As soon as the warranty is over, they will just empty your wallet.
@@zuilok some of them have well-known issues that are problematic, but if those are handled then they're just demanding of higher/more attentive maintenance, like anything German.
Informative and entertaining as always. Can you please do a similar video on the Mercedes M256 engine?
Good job on graphics! Wish the video spent more time explaining WHY it's preferred to inject water opposed to adding a second cooler, WHERE the water is actually "evaporating" into and HOW this evaporated water effects the stoichiometry of the internal combustion engines plus any clever air/fuel ratio tricksBMW uses when water is actively being sprayed to adapt

Ive never had these issues with my old Toyota Celica.
First off idk where you're from but windshield washer fluid is made from a methanol and distilled water blend..
Had a setup like this on my old drag car 20 years ago. Works well
I’ve use water injection for many, many years on my turbo cars. I use the windshield washer reservoir and windshield washer fluid (the -20 degree stuff) in the winter and usually straight water when temps are staying above freezing.
There's engineering then there's over-engineering.
Hi Jason, great video and explanation as usual. Is it possible for you to do an in depth video for a WRC shock and suspension systems? From the videos I've seen they've very sophisticated units especial for the off road version, handling the jumps and the smaller bumps and riding over rocks etc. How they control compression and rebound. The newer generation of vehicles seem to be exceptional at how they control a big bump and brake at the same time; The rebound seems to be very well managed as well as the ride quality. Thanks
New old stuff is cool. Was used in aircraft years ago, GM used it on the turbo charged 62-63 Oldsmobile Jetfire F85, GM called it Turbo-Rocket Fluid. Saab used it in the 80's and I use it now, works wonders keeping detonation down and allowing more timing.
We were using water/methanol injection under turbo boost back in 1980. We also had a MSD timing control unit that reduced the advance under boost.
I just watched a video of a runaway Detroit that had water fed into the intake and it seemed to take it well, it sparked my interest now I’m here
Nicely explained as usual, thanks! I wonder how this will affect reliability though...
We were doing this on medium speed diesel engines in the late 1970s. We had a mixing pump prior to fuel manifold. Power went up as did engine temps. We had to fit nimonic valves and seats as standard burnt out.
Very interesting video! My dad added a water injector to a mid '80s VW "Rabbit" that didn't have fuel injection, and it wasn't a regular carburetor. That weird application was what we had, and he said the water helped it. I imagine he was right, because he was an engineer and basically right about everything.
In the 70’s I worked on P-3 Orion aircraft jet engines. We had an ADI induction system on the aircraft. At hot air temperatures the water alcohol mixture would inject into the engines on takeoff. The pilots said it was a significant boost equivalent to having an additional engine.
Saw one nearly crash the other day, maybe thats why we're in the middle of upgrading xD
Very smart, I like it
So is this very similar to water methanol injection then? Pretty interesting. Thanks again for an eloquent explanation!
You are a badass. So well explained.
This is awesome love the vid and the concept I hope its successful my only concern is if one of those injectors leak and water pooling in the intake I'm also assuming that the water vapor is a small enough amount it wont effect the burn of the air fuel mixture
I worked on US Marine Harrier jets for years and the original version AV-8A version made in UK used a water injection system to increase thrust from the Rolls Royce F402 turbofan engine approximately 2,000 lb., from about 19,500 lb. to 21,500 lb., as I recall.
Would love a side-by-side comparison of SRT Power Chiller vs BMW M water injection systems!
Good explanation! Could you please slowly in the next videos ? it's hard for me that is not native :) Thanks
So cool!
This reminds me of the idea of a six stroke engine, wherein water is injected at the end of the fourth stroke, creating steam, which then provides another power stroke, the fifth; then the sixth stroke occurs, which is the exhaust. Still another improvement would be to implement a real Atkinson cycle wherein the expansion volume is greater than the compression volume (not just based on ignition and valve timing).
great, I love it
My dad was a Pratt and Whitney engine mechanic in ww2. He told me the R2800 radial engine in the F4U Corsair fighter plane used water injection.
Saab used Water Injection on the 99 Turbo in 1975. In fact you could buy a "Saab Water Injection" upgrade kit in Saab dealerships up until about 1987 for installation on the 900 T16.
Thank you
Very cool
HAPPY 3MIL!!!❤️
Wow! 5 liter of water create additional 50HP! that is truly Awesome innovation.Thank you sir for that simple tutorial🤝👍🏽
I knew a guy who sold kits for water injection that improved fuel economy dramatically. The atomised water also turns to steam expanding during the combustion cycle improving torque.
Hi Jason, along the lines of adding water to this engine, what is your take on the current trend of HHO decarbonising treatments? Do they really work, can they cause damage and has anyone done a before and after tear down to see the results?
Very cool. Where I lived there was a man who was always experimenting spraying water in his carburator because he had noticed that his car rode better when it was misty. This was in the 1980s and early 1990s. He was ridiculed by most car journalists, but now he got his recognition! Unfortunately long after his death.
