A. The quick answer is:
If you have fuel still burning as it is going past the exhaust valves, they will burn.’Lean’ burning that causes engine damage is addressed in our books.
Eagle-Research fuel savers completely bypass the issue. If you follow our instructions your engine will run cooler, not hotter… and your exhaust NOx will drop dramatically.
The more comprehensive answer (covered in more detail in our books) is:
Givens:1. ONLY vapor fuel can burn.2. Fuel can only burn in a narrow air:fuel mixture range.3. ONLY the fuel that is vapor when the spark plug fire actually powers your engine. 4. OEM fuel systems actually vaporize only a small percentage of the fuel before the spark plug fires.
During the initial combustion (of the vapor fuel) the liquid portion of the fuel then turns to vapor and burns. The problem is that this process takes about 25 milliseconds and most engines only have about 7 milliseconds before the exhaust valves open. So fuel would be burning out past the exhaust valves; burning them up and creating huge volumes of NOx.
OEM fuel systems prevent valves being burned (and excess NOx) by ADDING extra liquid fuel. When the initial combustion (fuel that was vapor when the spark plug fired) then turns the liquid fuel to vapor, the resulting mixture is now too ‘rich’ to burn; and the fire is quenched.
BUT now excessive hydrocarbons are going out into the environment. These ‘excess’ hydrocarbons are burned in your catalytic converter. This is a pet peeve of mine, because I believe fuel should be burned in the engine, where it can be converted into power.
There is another, more efficient method, that has been suppressed since the late 1800s…
Eagle-Research technology makes the engine use less fuel, but in ways that actually RICHEN the initial explosive mixture, three examples, depending on the technology:
1. We produce more vapor fuel from the same volume/mass of fuel going into the engine; so less liquid fuel is required to produce the same power.
2. Our combustion enhancement techniques cause the fuel to be burned more efficiently (faster, more complete and at the right time) so the exhaust gases leaving the combustion chamber are hundreds of degrees cooler than before the technology is applied.
3. We use water Injection to both increase combustion efficiency AND to replace the liquid portion of the fuel that OEM was using to ‘quench’ the flame. During the initial combustion, the liquid water is turned to steam, which quenches the flame. You don’t need to use liquid gasoline to quench the flame…
All this can be easily verified using the colortune sparkplugs (explained in the books) and a pyrometer or simple thermometer in your exhaust pipe. If you see a white flame in the colortunes or your exhaust temperatures rise, you are too lean and not quenching the ‘excess’ combustion.
The conclusion is that our technologies have addressed the ‘lean burn’ question to the extent that, if you follow our instructions, it is nearly impossible to create a condition that will damage your engine by excess exhaust heat.
