HHO impediments to mileage improvements

Let’s explain what HHO gas is and why it's different from Hydrogen "H2" gas.

HHO, sometimes called Brown's gas or Hydroxy gas, is a dangerous mix of two (2) parts pure Hydrogen “H2” and one (1) part pure Oxygen ”O” gas that is created when water “H2O” is turned into gas.  HHO is dangerously explosive and cannot be stored or compressed.  Hydrogen and Oxygen cannot be separated from HHO gas once they atr mixed.  In fact there are numerous documented incidents of people injured and killed trying to store HHO.

However, if the Hydrogen and Oxygen are separated when they’re created, each gas is much safer to use.  In fact, burning Hydrogen is as safe as burning natural gas. As for Oxygen,… well we can’t live without it, and is not, in and of itself, explosive!

To be fair, adding HHO into your engine’s air/fuel mixture does produce many of the benefits that pure Hydrogen does. People have been injecting HHO into their engines for years.

These efforts typically fail to achieve the expected results for two reasons:

  1. It's not safe (we’ve just discussed this).
  2. Without the addition of electronic devices that modify your vehicles exhaust sensors, air intake sensors and/or the vehicle's computer, the increased fuel mileage expected isn't realized on a continuing basis. (You can thank the EPA for this).

The U.S. Department of Environmental Protection (EPA), with the help of the auto industry, has developed, and mandated, a pollution control system for every US vehicle, both cars and trucks, in order to reduce pollution caused by the incomplete burning of fuel, and the creation of NOx, a component of Smog pollution, which is caused by excessively high engine combustion temperatures. 

If you get a chance, look on the web for pictures of Smog in Los Angeles in the 1960’s and 1970’s or Beijing, China today.  That’s the result of NOx pollution.

  1. The first component of your vehicle’s pollution control system sets the amount of air an engine can take in to reduce the risk of high combustion temperatures which produces the pollutant NOx, (Smog).  This is called the Air/Fuel Ratio. In reality, allowing more air into the combustion chamber would burn fuel more efficiently, but could cause higher combustion temperatures which, once again, can create NOx pollution (Smog).
  2. A second component of your vehicle’s pollution control system uses additional (unburned) fuel to cool down the combustion chamber and reduce excessive heat, which, as stated above, is the cause of NOx (Smog).

Your vehicle has an onboard computer that constantly checks for a higher than allowed amount of oxygen in the exhaust.  If the exhaust sensors detect too much oxygen, the computer instructs the fuel system to send more fuel to the combustion chamber, despite the fact that there's not enough air to burn it. because the Air/Fuel Ratio has been set by the EPA.  The unburned fuel lowers the combustion chamber temperature and prevents the creation of NOx (Smog).

What happens to all that unburned fuel?

  • Unburned fuel sent into the exhaust cannot do any work and therefore reduces your fuel mileage.
  • Some of it is absorbed by the vehicle's Engine Oil which leads to oil break down, more friction and engine wear.
  • Some of it forms carbon deposits in the combustion chamber which can foul spark plugs, causing misfires and a dangerous condition called pre-ignition.
  • Most of it is sent into the exhaust as unburned fuel which itself is a pollutant.

The EPA's solution to prevent polution caused by unburned fuel being sent out of the exhaust pipe and into the environment is the vehicle's Catalytic Converter, which burns most the unburned fuel before it leaves the exhaust.

What a system!  Control pollution by wasting fuel.  After all, “You” pay for the wasted fuel.  It’s not costing the Government any money.  In fact they get more taxes for every gallon you buy, and the higher the price the more taxes they collect. 

So let's summarize why HHO gas doesn’t increase mileage?

When HHO, which contains one (1) part pure oxygen, is put into the fuel mixture the exhaust sensors detect too much oxygen which causes the vehicle's computer to tell the fuel system to add more fuel as a way of reducing combustion temperatures and prevent the production of NOx (Smog).  The unburned fuel goes directly into the exhaust to be burned in the Catalytic Converter. Since it can no longer be used in the engine, it therefore reduces fuel mileage. Oxygen sensors monitor changes in exhaust oxygen levels continuously as you drive, so as more HHO is added, the vehicle compensates by adding more fuel, which, once again, cannot be burned.  Even the additional Hydrogen in HHO cannot overcome the effect of the additional pure Oxygen.  It's a vicious cycle.

HydroTube® is not an HHO device.  HydroTube safety and efficiently separates Hydrogen from Oxygen and keeps them separated!
