Not really. If you truly wanted to run your vehicle on vapor, you would not use gasoline at all. You would install a natural gas conversion kit. Formulations of gasoline would not change at all.

Yes, it may increase NOx, but this is why I have incorporated EGR into my lawn mower setup, and the vehicle will have the same thing, and possibly water injection to prevent the formation of NOx. For a bit of background info on me, I have taken a car in the past that had 3.1L V-6, turbocharged it, installed bigger injectors, installed an aftermarket more agressive camshaft, threw the stock computer in the trash and installed a Halltech computer. I then tuned it on the street and got it to pass the emmissions test on the dyno. If I can get that car to pass emmissions, then I KNOW I can get a vapor car to pass the sniffer test. |
Re: 3X Gas Engines Sniffing Vapors
<sigh> This thread misses the mark. Let me count the ways.
1) Most gasoline engines are about 35% thermodynamically efficient. There is no way to get 3 x 35% = 105% energy out of a gallon of gas. 2) Even doubling is the efficincy is impossible due to the Carnot cycle theroretical limit of (T hot - T cold) / T cold. 3) Natural gas engines never have liquid in the cylinder, so there is no combustion "hold up" during the power stroke. And nat gas efficinecy, for a given cyclinder dimension, is quite similar to a gasoline engine. 4) Diesel engines are more efficicient, yet the diesel fuel doesn't evaporate more than gasoline as a prelude to combustion. |

There's some flaws that I see........ 1. You assume the motor is running at perfect tune and in perfect shape. VERY few internal combustion engines are in fact in perfect tune and in perfect shape. I base all of my research on real world facts, not on laboratory "perfect world", no variables facts. 2. See #1 3. Natural gas has a MUCH lower BTU than gas, but you say that Natural gas effeciency is quit similar to a gasoline engine of comparable size. This is more proof that burning a vapor is much more effecient than trying to burn liquid. 4. Diesel fuel has a MUCH higher BTU rating than gasoline, and requires a MUCH higher compression ratio in order to self ignite the fuel. Since the diesel burns at a slower rate than other fuels, diesel engines have a longer stroke compared to the bore to take advantage of the slower burn, and they have a smaller rev limit. Not to mention that modern day diesel engine fuel systems are VERY similar to gasoline direct injection systems in that VERY high fuel pressures are used, thus helping to vaporize the fuel. |
