You won't get anywhere close to 15% increase with HHO. It has been proven and verified by factual scientific study that HHO generators are a waste of time on vehicles.
No one should ever buy plans for an HHO generator either. It's nothing more than simple electrolysis. Electrolysis has been around for what seems like forever. Hell, I even made an HHO generator in my high school chemistry class. The information is well known and well documented... and above all... FREE.
In addition, look up polar covalent bonding and you'll understand how much energy it takes to separate hydrogen and oxygen bonds, how much energy is lost in the process, how little is produced, and why it's useless in a vehicle.
Every single HHO kit, information packet, or instructions that are sold are all a scam. Period. These companies try to promote the latest and greatest "invention", but they are all the same exact process. They continue to claim that they have a secret catalyst, or a new rod plating technology, or a special electrical modulator, etc. Again, all of this has been around for decades, and it's nothing new. In addition, you're still producing only a few measly liters of HHO per MINUTE. Your engine will gulp down that much air in a SECOND. Think of a dilution factor in the range of 10,000:1, and you'll see why you won't get any improvement with HHO.
Oh, and diesel133 has no clue as to what he's talking about when it comes to HHO. Here's an example:
HHO is 3 times more potent than gasoline? Really? Hmmmmdiesel133 said:
Gasoline = 30735.81 BTU/L
HHO = 9.54 BTU/L (at atmospheric pressure, same as what's produced on an HHO generator)
Gee, does that look like HHO is 3 times more potent than gasoline? :hehe:
And the whole "conservation of energy" is piss poor and misguided application of physics. It's a common trick that HHO promoters use. They try to validate their claims with "scientific equations" that are simply either not true, or not applicable and thus misconstrued (just like the link that he posted... the information there is laughable at best). Again, look up covalent bonding, and you'll see that there is a measured amount of energy it takes to break hydrogen and oxygen bonds. In addition, you'll find out that it's not 100% efficient. As a matter of fact, you spend more electricity to break the bonds than what you get back in actual useable energy. So in the end, you get a net loss, rather than a gain. The best HHO kits out there produce up to a max of 3 liters per minute of HHO. Since we can clearly see the amount of BTUs that HHO has, we can understand quickly why HHO has very little to no effect.
Oh, and this had me laughing too:
No, HHO gas does NOT have those properties. Earlier you mentioned that to run HHO, you must lean out the fuel. This is true, but why? The reason is that as the fuel mixture becomes leaner (especially true with gasoline), the burn rate slows down. This is how you create hot spots on a gas engine and burn it up. Supplementing hydrogen into the mix increases the burn rate back to normal levels.diesel133 said:
However, here are the problems... and it's something that no HHO promoter will tell you.... In order to even start to see a benefit from hydrogen, you must be at least 18:1 AFR on a gas engine (normally at 14.7:1), and to run optimally, you should be at about 21:1 AFR (insanely lean). Now, to make up for the lean condition, you need an adequate supply of hydrogen. Well, with the best HHO kits making at most 3 liters per minute, you are seriously lacking the volume of hydrogen needed to make up for the lean condition. Instead, you need an onboard tank of pure compressed hydrogen pumping in enough volume to make up for the difference, but this is not what an HHO kit is all about. So the end result is... no mileage gains from HHO. Instead, you'll increase mileage simply from a lean condition, but with something like a gasoline engine, you'll burn it up faster. For a diesel application, our engines gulp in much much much more air than a gas engine, so HHO is even further diluted, and thus becomes even more useless.
Seriously, if you want to experiment with HHO, do not buy plans, do not buy a kit, don't fall for scams. Your money should only go to Home Depot for parts, and to your local water department for your source of water to run it. Don't be surprised when nothing happens. In fact, I have a nice little experiment for any HHO user to try, and it specifically applies to diesel engines (since they have less fuel management sensors):
Hook up an HHO generator to an on/off switch accessible inside the cab (preferably where the driver can easily reach it). Find a nice long stretch of flat road. Do not use the cruise control, but instead maintain a steady speed with your foot on the accelerator pedal comfortably where it won't move. Once a steady speed is maintained, flip the switch and turn on the HHO generator. If it actually works, you should pick up speed without pushing any further on the accelerator.
This works for diesels because they don't care what the oxygen content of the air is, nor do they even monitor the air/fuel ratio. So there's no sensors to trick, nothing to do whatsoever. It's a simple and straightforward experiment.
the feedback from his eBay customers all say it works, there's just too many people saying it works who are not out there being paid too, or promoting it but just saying they have it and works so I'm giving it a shot plus my brother will buy it off of me and use it to weld. I'm actually more prepared to see this thing not work haha but who knows, not trying to be cocky here but did you ever see it in person or try it pocket?
