Remember back in the '70s they advertised a "Water Injection" system that connected to a vacuum port on the manifold and let a small amount of water into the intake. It was supposed to stop knock and clean the combustion chambers and increase efficiency by allowing timing advancement.

Has anybody ever tried one of these on a car or a coach? What were the results?

Also what is the scoop on the "Hydrogen Generator" that is supposed to increase mileage?

Hydrogen fuel is supposed to be an answer to fuel economy. The problem is how to make it if you want to produce your own. It takes a lot of power to create hydrogen.

In my experiments, I felt that pure hydrogen, not oxy hydrogen was best. And it worked best while going down the road on cruise. The hydrogen would replace the fuel and maintain speed as the cruise would drop the gasoline feed, sort of regulation as needed.

The home brew hydrogen guys use the electrodes in water but again, high power needs to make it and it still has oxygen in the gas which makes it highly explosive. Take that oxygen out of the mix and the hydrogen is easier to control and regulate.

Commercial hydrogen units are large and have other needs. The car industry wants to put hydrogen filling stations along the highways, like gasoline stations where you would fill up and pay the big bill. Of course, none of this infrastructure is available yet.

Oldsmobile had water injection in the mid 60's on the F85. IIRC the dealers sold the special jet away water for a lot of money although probably less than what people buy water bottles for today. It must have helped a little bit or an OEM wouldn't have offered it. I think it was part of the turbo option.

I experimented quite a bit with water injection in the mid to late 80's (on muscle cars and 4x4's - not on GMC MH's). It mainly works by cooling the intake air - since the energy required to vaporize the water comes from the intake air/fuel. Basically - kind of like an intercooler.

It worked a bit - but I recall that ultimately the net power was down - probably due to the water displacing some of the fuel. I even experimented with adding alcohol and other additives to the water, but eventually gave up trying to find the "holy grail".

Most of the hydrogen kits I've seen (on the net) appear to be nothing more than snake oil. I'm not going to hook up a Skippy's PB jar to my air cleaner and claim 20 mpg...

YMMV.

Water injection was used sucessfully in aircraft as an anti detonate. It can be useful in cars. I have run it, also water/alcohol, and more recently pure methanol in my turbo corvette.

By itself, water offers no benifit. However, IF you get the mix just right, you can get away with more comression than the fuel would otherwise allow, an/or more timing.For an ~8:1 conservatively timed motor, it may not be worth it. Youd have to play with the timing
Snow performance, AEM, and Alky control are very good units, none cheap.

Hydrogen generators are snake oil.

The primary function of water injection is to reduce peak combustion chamber temperatures. The heat capacity of water and the phase change to steam absorbs a lot of heat. Water injection has the exact same effect as EGR - reduces chamber temp and in so doing it reduces the production of NOx. Both EGR and water injection allow more ignition advance due to the lower temps. The extra advance does not directly help economy because you've reduced the thermal efficiency with lower temps. There is a slight gain as you are forced to open the throttle slightly more to make up for the torque loss. This additional throttle opening gives a slight reduction in pumping losses.
Olds used water injection on the turbo 215 V8 in 62-63 cutlass to lower knock.
Bottom line - don't bother with water injection. Set optimum spark and fuel values and you should not have to worry about knock.

Rick M.

I tried it on my coach. I went old school with an Edelbrock variJect system. Not sure i ever got equal water in each barrel. I have EFI and so fuel and spark is pretty much controlled. I could see no difference in the exhaust temperatures. I am sure it does work though as early tractors introduced water for carbon and heat, not to mention planes.

I suppose I was thinking about delaying power enrichment (power valve) as gasoline is an expensive coolant. The truth is it made me nervous. Run out of water and burn a valve or piston. Heat in the combustion chamber is one that I would like to control with some assured technique.

As a side bar, when Randy Van Winkle and I experimented with spark during Lean Cruise( 16.4+ to 1 air fuel) we could not advance the spark far enough to get a knock on th eknock sensor before power was compromised. The pistons were being driven backwards before it pinged. This was crusing easily at 62 mph; given a hill with too much spark and EFI will ping with the best of them.

Water injection was/is real. I am almost surprised that none of the new processor controlled engines are taking advantage of it.
How common was it? Every DC-6 with R2800 still has it and many are still in use in cargo service. It is used on take-off and it is called ADI - Anti Detonation Injection and it is a water alcohol mix with the alcohol only there to prevent the system from freezing.
Many of the famous WWII interceptor and fighter aircraft were so equipped. It was one of the reasons that a P-51 could bushwack an ME-262.

The way it really works is that it does cool the combustion process, but in doing so it changes state. This kind of makes it work like an internal combustion steam engine - gobs of torque.

Two big problems:
The additional pressure delivered can easily damage engine parts like rod bearing and head gaskets.
The extra water that can condense out of the combustion gasses can cause unanticipated corrosion problems.

But, we had fun with the program.....

Did the G model get turbo-fan engines as a mod? Do the fanjet engines use or require water injection to provide the cooling at Max Emergency Takeoff power?

The G has the same turbojets it came with, J-57s. The H is the only one
with turbo fans, TF-33s if I remember correctly.

Water is used to increase the volumetric density of the air, aka more
thrust, so it can actually get off the ground on a hot day.

G'day,

I was a Mechanical Accessories Repairman (ABR 42251) in the USAF. The B-52 H2O injection system was a mechanical accessory. It was
used on all the B-52's that had the J-57's. IIRC (it has been 50 years!) the H model with the TF-33 did not have the system as they
produced enough thrust enough thrust to get the 52's wings flapping! ;-)

I put a turbocharged/water injected 215 Olds in a Corvair van. It had the original factory water-alcohol injection system installed because the engine had a 10.25:1 compression ratio. I ran the van that way for about a year before replacing the turbo system with a 4 barrel. It was a PITA to keep the turbo system/water injection working right. Back then you could go to most any Olds dealer and find an F-85 turbo system in their trash barrel. Apparently the dealership mechanics had trouble keeping them running right too. I think I still have a couple of the F-85 turbo systems that I wanted to put on a 455, but I'm too old now to care about such things.

Buick ALMOST btought it back on the turbo Riviera and turbo Regals. In the dash idiot light backlit strip there is one cell with no bulb behind it. If the sun hits it you can read POWER INJECTION. They went with the air to air intercooler instead in 86/87 and scraped the alky/ wàter injection.

The Rolls Royce Dart turboprop engines used water-methanol injection as a means of increasing take-off power. The purpose of the water-meth was to drop the TIT (turbine inlet temp) so that extra fuel could be added without burning up the turbine blades. Many an operator learned the expensive way that they needed to keep the water-meth tank full and respect the max power time limits on take-off. We saw many an engine come into the shop with only the stubs of the blades remaining.

The recommended water-meth mixture was a 60/40 methanol to water ratio, and our test jocks claimed the high methanol content added power without any significant additional heat. If a mix using more water was used, power dropped slightly for a given fuel flow & TIT.

Of course a turbine reacts somewhat differently to water injection than a piston engine, so very little of this info directly applies to our GMCs.

Many years ago I played around with water injection on a 914. Which was a simple flat 4 cy. early fuel injection . I had 2 switches in the car, one fed the injector and one added resistance to the the head temp sensor.I felt it helped a bit with temps, and maybe a little to the ump. I got the idea when converting back to fuel injection from carbs. Initially I had it running rich. Then one foggy misty mornign I went to play around and noticed it liked the damp air when running rich.
