I was talking to a couple of guys the other day that have fabbed up a hydrogen system on there cars and they went from getting 17 mpg to 26mpg. They had them on 97ish Ford Rangers. My dad and I are going to make a few systems for our older cars and run them for awhile and then well see about putting it on the HHR. Once we get these built and hooked up I will post some pictures. If you guys want more info look on YouTube for Stan Meyers and Roy Mccallister, or just Hydrogen there is alot videos so check it out. Maybe some one will be a little braver than me and go ahead and put it on the HHR, im just not sure and with it still under warrenty dont want to accidentally screw something up.

 

Dude....please stop the madness. Please stop the hype. This stuff is crap.
No we don't want more propoganda...

Ok..lets try a different approach.

Those "couple of guys" you were talking to are idiots. Not in the "yo mamma" sence of idiot, but UNEDUCATED. You and your Dad are also. I am uneducated about many many many things, However this is not one of them.
So help me help you....no help me help us ALL.

STOP THE MADNESS.

 

Actually Hydrogen gas injection has been proven to increase mileage and remove emissions.

article is a couple yrs old but still good

 

He did not say hydrogen injection. He said simply hydrogen. Hydrogen injection is different than most of the recent junk on the internet about water for gas and such things.

Change the name of the thread to Hydrogen Injection please?

 

Hmmm,
That is true. perhaps it is not hydrogen injection...

Cleveland, does Hot Air Injection help?

 

Sorry i click post before i was finished...lol
Could you please explain what type of "system" this is ecl. Didnd't mean to jump down your throat so quickly, but the recent increase in gas prices have made people so GULLIBLE to believe anything. So I am quick to CRUSH the BULLS&%@

 

I almost didn't reply because I thought "hot air" was some sort of a joke. I don't see a smily face anywhere?

LOL

Seriously, you mpg does suffer (at least mine does) before the car is up to a steady operating temp, so if your talking about a hot air "intake" to get your car up to operating temp quicker, I guess that would gain a very small amount of FE in the colder states for the first 5-10 minutes of your drive. You would need someway to turn such a "system" off or risk losing power once the engine was warm or in warm weather. These little hhr engines warm up quick so I think working on fuel efficient driving is more worth it. BTW , I have no idea where you would get lots of hot air in Minnesota on a January morning to run up your intake (or wherever needed to warm the engine) anyway?

 

No, hot air injection does not work. The colder the air, with proper atomization of fuel, the more expansion you create when ignition happens. Therefore more power. Yes, you add more fuel with colder air but then you just end up reducing the throttle position because you are only wanting to produce the power you need for the driving you are doing at the time. Long story short, hot air will not help. I could write a book...... Yes, there is an issue of better fuel atomization at higher temperatures but then you need to use a supercharger or turbo to make up for the high temperature mixture low power potential. That takes power to run and has losses, no free lunch.

 

Just stirring the pot a little bit, but have ya'll ever heard of the Adiabatic, Or Hot Vapor Cycle Engine, that Smokey Yunick worked on? Early testing showed some serious promise (IIRC, there was a working prototype Dodge Omni with the 2.2 that made around 300hp or so, and a 2cyl that made 150hp and got 50mpg). There are a few pages on Google search about it, here's a translated page - http://schou.dk/hvce/
