Making combustible gas from water is proven technology and has been around since the 1950’s. When talking about combustion engines we’re not talking about a stand alone fuel source or renewable energy. We’re talking about a combustible soup, a mix of hydrogen and oxygen, that assists the combustion cycle. When used correctly with an efficient set of plans, this system does save on gas usage. Your vehicle will burn less gas increase horsepower and emit cleaner emissions.
We’re mostly familiar with the catalytic converter that has necessitated the use of unleaded gas since around 1975. 3-way scrap catalytic converter price guide break down hazardous carbon monoxide to harmless carbon dioxide. They also break down toxic hydrocarbons into carbon dioxide and water while reducing nitrogen oxides to regular nitrogen and oxygen. For the Cat to do it’s job it has to be hot which can take a while. In order to meet strict emissions standards an air pump has been added to heat the Cat up sooner and reduce harmful emissions quicker. Pump air into the exhaust and it gets hot more quickly. When the Cat reaches 400 to 600 degrees Fahrenheit it begins to clean up the exhaust.
In summary, if you total up all the low numbers it works out to be $144.00 totaling the high numbers equals $333.00. If you are good, and can strip a car down in about an hour or so that is nice return on your time.
With the consistent progress in the chemical formulation and metallurgy, this device has become very high-tech. It is an effective gadget and is very efficient.
There are a host of new “clean diesel” cars hitting the market you might want to take a look at. The miles per gallon figures are staggering. How about the Volkswagen TDI Golf that gets 42 mpg in the city and 49 on freeways? How about the 35 mpg BMW 335D? These are just a few of the diesel vehicles coming onto the market as a non-hybrid method for dealing with high fuel costs. To increase performance, each is fuel injected and highly tuned.
The O2 sensors also tell DME if the air from the air pump is reaching the catalyst. If the secondary air injection system is working properly DME should see a drop in voltage in a conventional O2 sensor. On the newer A/F sensors the technician will need to access fuel trim data to see if the fuel system is trying to adjust when the air pump is artificially triggered. So the air pump pumps air but there are some mechanical controls in the way of the air actually getting to the exhaust side of the equation. There is a vacuum switchover valve (VSV) and a vacuum operated “Dump Valve” that when vacuum is applied by way of the VSV allows air to enter the exhaust through a check valve which keeps exhaust gasses from returning through the “Dump Valve” damaging it and the pump.
Here’s the takeaway: if you intend to continue having mechanics perform all of the maintenance and repair work on your vehicle, find someone you can trust. In the meantime, consider buying your auto parts online and learning how to install them on your own.
