This is a Hydrogen installation kit, with installation video

i watched the video, because i'm a curious bastard.

1. that's a rusty/chipped fire extinguisher bracket that is being used upside down as the 'mounting bracket'. i also recognize the clear cylinder, it appears to be from a water filtration system. the top appears to be a custom contraption, though i need to do some digging on that. the fact that there's no visible fuses on an electrical device that connects directly to a battery is a huge no-no. the good news about that is if your car burns down, you can likely sue this company for everything they have.

the primary assumption that must be made is that it's producing a meaningful amount of hydrogen. if it isn't, the entire device is the same as the "fuel shark" cigarette lighter device that was only a capacitor and an LED, and has become internet famous for being absolutely useless.

2.he's explaining to connect to the crank case ventilation tube BEFORE it enters into the PVC valve. specifically, if this entire contraption works as explained, and the pcv valve is operating as it should(many start sticking after years of operation, sticking closed would be horrific with this device), it should only open when the engine is revved above idle, allowing fumes to be passed through into the intake. this means that the valve is closed during normal idling periods like waiting at stop lights, or in stopped traffic. with the method explained to connect, it means that this contraption is now pushing explosive hydrogen gasses into the crankcase. explosive gasses behind the piston, if built up to any substantial level, as they would need to supply a running vehicle enough to effect gas mileage, means the engine block will explode, it's just a ticking time bomb as to when. so using a device like this, if it produces a meaningful enough amount of hydrogen to effect gas mileage, means you should have a backup vehicle, replacement engine block, and wear ear protection when operating the vehicle in heavy traffic.

3. what's also interesting is that there's no alteration to the vehicle computer. we're now introducing extra gasses into the combustion cycle. to properly control the combustion cycle, the mixture must be adjusted. there is no mention of alteration to the vehicle computer systems for this. if there is no adjustment needed, it fundamentally means that there's not enough gas being input into the motor to alter the combustion cycle.

propane conversions for gasoline injected vehicles have been around for decades, i would encourage you to look into those kits. they operate on very similar principles and the science behind them is sound, though they don't offer any magical fuel benefits outside of a difference in fuel costs.

 

Good lord man

 

Not really. The other end of that hose is attached to the intake. Any time the engine is running, there will always be some level of vacuum in that line. The "V" in PCV is for ventilation.

 

You'll hear negatives because basic laws of thermodynamics mean the system is a waste of money and increases fuel consumption. You need more electricity to generate hydrogen than the energy content in the hydrogen. That electricity comes from the alternator, which has a load on the engine. That means there's more parasitic drag on the engine than propulsive power from burning the hydrogen.

 

Thanks for reminding me that I still need to install a Mr. Fusion in my truck.

 

Electrolysis is about 70% efficient. The alternator is about 70% efficient. The engine itself is about 30% efficient. Efficiencies multiply, so at the end of the day you get about 14% of the energy you burn in gas converted to hydrogen.

What is the mechanism by which feeding hydrogen into the intake supposed to improve mileage? It has a lot of heavy lifting to do to overcome the cost of that hydrogen.

As a chemical engineer who has worked for several large oil companies specifically on problems relating to optimizing combustion for internal combustion engines and also drives a Tacoma, I know something about this very thing-- which I think is what you are looking for. My takeaway is this thread has some really good responses to your question and you should listen to them.

Not sure if OP is serious here, but if you are, please do some experiments and post results. We would all love to see it.

If you actually do want to make H2 gas by reduction of bicarbonate, a good starting point would be to calculate the cost of one batch of starting materials vs. the value of the energy obtained by combustion of the H2 yielded. In brief, if this was a reaction which had any value, chemical companies would already be doing it which would drive up the price of bicarbonate to the point it would not be economical for you to compete.

A good entry point might be to start googling 'what is Avogadro's number' and 'what is energy conservation'.

Edit: I finally watched the video
and OP this looks like it would probably have some effects. Specifically the gentleman in the video is performing hydrolysis of a sodium hydroxide solution by application of battery voltage and venting the gases into the PCV valve. Please replicate his setup and post your studies. In particular the effects I am eager to see are how much faster your rubber hoses and engine oil are degraded by exposure to the reactive gases and caustic vapor emanating from the contraption.

The only upside I can imagine is it might help keep your PCV valve clean.

 

1. people in the UK do LPG conversions. It's been done. Don't know why. Fuel is also expensive there.

2. CNG vehicles exist in America. They have for a long time. There are CNG stations.

last person I knew with one had one provided as a company car for long distance commuting. Supposedly he also put one in an SUV.

where do you get the fuel...
how safe is it...
if it's high pressure, flammable, etc. well...yeah...

vehicles designed for gas are kind of safe. Somewhat.

 

Every Tacoma already has a small hydrogen fuel cell called a battery. Pipe the battery vents into the PCV line and see what happens.
