Hydrogen Generating Module to Help Your Car? 506
TomClancy_Jack writes "A Canadian man claims to have invented a hydrogen
electrolysis box that can be fit onto any existing internal combustion
engine. He claims that engines using his "H2N-Gen" box
'produce a more complete burn, greatly increasing efficiency and reducing fuel
consumption by 10 to 40 per cent - and pollutants by up to 100 per cent.'

When you plug something into your cigarette lighter outlet, the voltage regulator senses a dip in voltage, and sends more charge into the alternator feild coils. This causes the alternator to generate more power by adding more flux. The extra flux causes the alternator to become harder to turn, and the engine compensates by burning more gasoline.

you have extra power in your car because of the altenator. it is turned because your car is running and producing more power than you are using unless you're going up hill or accelerating. If you're at a dead stop and your engine is at idle where is the power of the combusing gas going? into heat, noise, and the altenator recharging your battery which is probably full after the first 5 min. So you have extra electricity.
No. There's no extra energy. The resistance of the alternator to turning is proportional to the electricity generated. Add more electrical load, and the alternator is harder to turn.
They have tried using this extra electricity for charging batteries for use in hybred electric cars but you have the offset of dragging around large batteries that weigh 50 lbs each and you have to have a couple to really get any extended electric mileage out of the system.
No. Hybrids are successful mostly because they recapture braking energy and allow the engine to be shut down when it is making more power than necessary.
They have tried using this extra electricity to power flywheels to store the power and release it back into the system when you release the brake but again you have this giant heavy flywheel to drag around.
No. Such systems were mechanical variants of a hybrid; that is, capturing the energy of braking and storing to use to accelerate the vehicle. There were some systems that used a huge flywheel as the vehicle's store of energy, but they never caught on.
The article uses this electricity to release the power that is naturally stored in the water solution. Einstien proved that all mater has a great deal of energy but getting it out has always been the problem. With gas we are getting no more than about a third of the actual energy out of the material we use up. That means that out of a gallon of gas we get the output of 1/3 actually making our car go. The rest is waisted.
No. Cars are not nuclear powered. Einstein has nothing to do with internal combustion. No material is used up or converted to energy. We're just rearranging the matter to a state of less potential energy. We harvest that energy as heat, which we then try to convert into kinetic energy. We only convert about 1/3, the rest stays as heat.
If we made an engine that recaptured the unspent fuel or had a system of burning the fuel completely we would have a better ratio of conversion from matter to energy.
No. There is very little unspent fuel, less than 1% in most modern engines. Again, the car is not nuclear powered, no fission or fusion taking place, no matter converted to energy.
Now we can't get the entire subatomic amounts Einstein was talking about but we can have the best chemical reaction amounts if we make a system that extracts the energy more effeciently from this reaction.
I don't know what you're talking about here, and I don't think you do either.
An example of this is when we add oxygen to gas (common practice now) to make a better chemical reaction inside the engine. We are taking a cheap additive and mixing it with a relitivly expensive main ingredient to make it burn better. If we add different chemicals we get different outputs, some help some hurt, most do both. Adding water helps the combustion by adding pressure and oxygen but hurts the engine by pressing water vapor into the oil and making our engine grind and wear out. Additive are nothing new and they have been proven to work. The main difference is that the right additivs are dangerous and hard to introduce to the system easily.
No. Oxygen additives don't produce a better chemical reaction, just a cleaner version of the same reaction. Adding water doesn't help combustion, just try adding some to your campfire. The old water injection systems reduced intake charge temperature by the phase change of water to steam, allowing greater compression ratios and greater efficiency.

The 35% efficiency is the thermal cycle efficiency, with 65% of the heat being lost through the cylinder walls, cylinder head, and exhaust.
The problem is that to maximise the T1-T2 difference, heat loss must be minimised, and the compression ratio needs to be high since the gas expansion is what drives the temperature change. Spark ignition engines cannot run at very high compression ratios due to the phenomenon of pre-ignition, and this limits their efficiency. Diesels can run at very high compression ratios indeed, because the fuel only burns when it is injected. Their burn cycle also reduces heat loss. That is the reason why Diesels are more efficient than spark ignition engines. Direct injection gas engines (semi-Diesels with auxiliary spark ignition) have been developed by the Japanese but they still require a fuel that costs more to refine than Diesel, and are no more thermally efficient.
Adding hydrogen can promote more complete combustion and perhaps allow a slightly higher compression ratio, but it still does not get you anything like Diesel efficiency. (You can actually raise the compression ratio a little by injecting ordinary water, but the complication -DI water, extra tanks adding weight, injection gear- outweighs the advantages.) And anyone who has spent time fighting, as my R&D dept did over a period, with those water/KOH hydrogen generators will be aware of the problems. Like keeping the KOH out of the output gas stream.
In short, sorry, nothing to see here, Sir Harry Ricardo did all this stuff so long ago it was already old when I went to U and I'm over 50.

It would be a trivial matter of telling people to refill it more often. So we have to assume that most of the 20lb box ISN'T water. Let's be generous and guess that half of it is a 1 gallon (10lb) water tank.

Liquid Injection. These products add liquid into the fuel/air intake system and not directly into the combustion chamber.
The EPA has evaluated: Goodman Engine System-Model 1800; Waag-Injection System*.
Ignition Devices. These devices are attached to the ignition system or are used to replace original equipment or parts.
The EPA has evaluated: Autosaver; Baur Condenser; BIAP Electronic Ignition Unit; Fuel Economizer; Magna Flash Ignition Control System; Paser Magnum/Paser 500/Paser 500 HEI; Special Formula Ignition Advance Springs.
Fuel Line Devices (heaters or coolers). These devices heat the fuel before it enters the carburetor. Usually, the fuel is heated by the engine coolant or by the exhaust or electrical system.
The EPA has evaluated: FuelXpander; Gas Meiser I; Greer Fuel Preheater; Jacona Fuel System; Optimizer; Russell Fuelmiser.
Fuel Line Devices (magnets). These magnetic devices, clamped to the outside of the fuel line or installed in the fuel line, claim to change the molecular structure of gasoline.
The EPA has evaluated: PETRO-MIZER; POLARION-X; Super-Mag Fuel Extender; Wickliff Polarizer [fuel line magnet/intake air magnet].
Fuel Line Devices (metallic). Typically, these devices contain several dissimilar metals that are installed in the fuel line, supposedly causing ionization of the fuel.
The EPA has evaluated: Malpassi Filter King [fuel pressure regulator]; Moleculetor.
Mixture Enhancers (under the carburetor). These devices are mounted between the carburetor and intake manifold and supposedly enhance the mixing or vaporization of the air/fuel mixture.
The EPA has evaluated: Energy Gas Saver; Environmental Fuel Saver; Gas Saving and Emission Control Improvement Device; Glynn-50; Hydro-Catalyst Pre-Combustion Catalyst System; PETROMIZER SYSTEM; Sav-A-Mile; Spritzer; Turbo-Carb; Turbocarb.
Mixture Enhancers (others). These devices make some general modifications to the vehicle intake system.
The EPA has evaluated: Basko Enginecoat; Dresser Economizer; Electro-Dyne Superchoke; Filtron Urethane Foam Filter; Lamkin Fuel Meter
I have my doubts about this concept... (Score:2)
This sounds very similar to other products I've seen around in the past, just maybe better engineered, since references are made to older ones being rudimentary.
At a previous job of mine, we tested one of the older products, and also made our own electrolyzer to compare it against. Running an engine connected to a generator with a constant load, we compared fuel economies and did pollution testing. Following the directions that came with the electrolyzer we bought, there were no improvements or changes.

They are making pretty much the exact same claims - although a lot less stridently and with no exact claims of fuel savings.

This one needs filling up with water every 5,000km - and since it fits into a 14"x14"x20" box - you know there's not a lot of water inside.

Brown's Gas is not hydrogen (at least not only) (Score:2, Informative)
It's hydrogen and oxygen, the exact amount released by electrolyzing water. This man is not just injecting hydrogen into the air intake, but one oxygen for every 2 hydrogen.
This results in a re-combining of the hydrogen and oxygen during combustion. This also creates high temperature water vapor which assists in the combustion process, increasing power output from the ordinary gasoline combustion. Brown's gas burns at several thousand degrees centigrade.

Presumably if/when this works for the big guys the company will have more money to throw around. Economy of scale will kick in and bring the device to the average consumer at a lower price.

Aren't diesel engines no-emission? My understanding was that diesel engines only had unburnt fuel coming out which could then be recaptured...

The total mass in a system must stay the same. That's my poor paraphrase of the law of conservation of mass.
So, you have to get the mass of incoming air and incoming fuel to come out of the engine. It will have the same mass as the sum of the mass of incoming air and fuel. If there's no emissions then diesel engines violate the law of conservation of mass.
Sorry.
