Mike Kerhli Interview

Fulesaver-MPG Inc.'s Mike Kerhli has been selling his EFIE devices for about a year now. He tinkered around with some plans from Eagle Research's George Wiseman and found that he had perfected the result enough to know he could save a lot of people some serious time so he decided to start a business doing just that.   How successful has he been so far?  He's sold over 3000 of these devices.  Until recently, he's been working 20hr days trying to keep up with demand. 

 What are these devices an why do you need one?  If you install an HHO kit on a car with an electronic fuel injection system, the air output through the engine becomes oxygen rich due to better combustion.  The Oxygen sensor on the output will flag this condition and cause the engine to send more gasoline into the engine.  What Mike's EFIE devices do is correct that condition allowing you to achieve the full benefits of an HHO Kit.   Mike is responsible for portions of the Water4Gas manual.  His information in this area is referenced by Ozzie Freedom and includes links to his site.  Kerhli recommends the manual as a big time saver to anyone wanting to start experimenting with this technology. 

Today, Mike is focused on adding to his product line. Next up for production is a wide band oxygen sensor or AFR sensor.  Certain new Japanese vehicles require this type of sensor to take advantage of an HHO Kit. It's interesting, this may explain why Mike Allen at Popular Mechanics received incorrect in his testing results. 

More on this topic later. 

EFIE Guy Mike Kerhli: Pulling Together HHO Proof

I had a fascinating conversation today with Mike Kerhli from Fuelsaver-MPG Inc., makers of EFIE (Electronic Fuel Injection Enhancers).  I'll be posting excerpts from that conversation on this website and on  

Mike sent me over a nice list of HHO research studies that have been done around the world.  Apparently, HHO has been studied scientifically a bit more often than the Mike Allen's of the world will find comfortable to tolerate. I'm going to be posting that research here for your perusal starting with this article:

Allgeier, T., Klenk, M., Landenfeld, T., Conte, E., Boulouchos, K., Czerwinski, J., “Advanced Emission and Fuel Economy Concept Using Combined Injection of Gasoline and Hydrogen in SI Engines,” Publication #2004-01-1270, March, 2004, Society of Automotive Engineers, Troy, MI.

  • Abstract:  This paper presents data indicating that a hydrogen-enriched gasoline fuel mixture, in a conventional spark-ignited engine, produces improvements in engine efficiency and emissions.


I was able to actually track down one of the authors, Tilo Landenfeld, all the way in Germany.   In the coming days, I hope to be able to share more information about what I learn here. 

There are a number of SAE articles concerning HHO.

Dynojet Research and HHO Gas Devices

I'm always on the hunt for scientific proof that hho gas devices work as advertised.  What's needed here is a set of valid tests on a dynamometer.  These are hard to find but if you browse this site, you'll find lots of links to the various research performed on hho gas.  Hydrorunner is a company that makes hho gas kits and they've posted their dynamometer testing results on their website.  After clicking around a bit, I noticed that the maker of the Dynamometer was Dynojet Research.  Now here's a company that should know a thing or two about testing an HHO device on a dynamometer.  I'd love to interview someone at Dynojet about this:  if you're reading this, email me:

HHO Vs Popular Mechanics

I've been following Popular Mechanics' Mike Allen lately as he writes about testing HHO devices and I've got to say I've been very disappointed so far.    At the time I spoke to him, he had a Water4Gas manual on his desk and when I asked him a question about an EFIE, he flipped to the section of the ebook and read a couple lines to show he was aware of the issue.  But he did not have one installed at the time.  

Here's the problem.  Mike Allen says that people who experience HHO gas saving improvements are imagining  the results based on a change in their driving habits.  They accelerate less quickly, lay off the gas more often and in general drive in a way that maximizes gas mileage.   Here's the problem I have with that.  People I've spoken to actually report having more torque with these devices and say that they drive faster not slower.  Allen looks sort of funny claiming he's tested these devices and that his pretest conclusions were right when in fact he ends his article by saying he's been testing them just like everyone else has been--flat road testing with an electronic gadget attached to the computer to detect mpg changes.   So based on that, he tells us these things don't work. Then he tells us only a dynamometer test would be conclusive.  Well, which is it?   It's not surprising, Allen insisted these units had no value even before he ran a test.   Then he ran a test and concluded they had no value but then ends his article with an admission that his was another of the invalid tests he criticized.  Do you see what I mean here?  

Here's what I think.  I think Mike Allen should use his pulpit to encourage real testing done by labs authorized by the EPA to run scientifically accepted tests to prove or disprove the efficacy of these devices to save gas.    Is it really going to kill his career to simply say, "hey, I adamantly detest the idea that these things actually work but I have to be honest and admit that  running the type of test required to once and for all establish the truth of HHO gas devices."  Is that going to kill you to say it, Mike?    The EPA has been running tests on these things for 30 years. Trust me, they know how to do the testing. We dont need Popular Mechanics to pretend they know how to conduct the test. 

In the meantime, thousands of people continue to report success with these HHO devices including the gentleman from whom Mike Allen purchased his kit.  

Keep in mind that the National Hydrogen Association has endorsed HHO gas devices which they refer to has hydrogen fuel injection systems.
