User ID: 75756457 Canada 12/14/2019 06:54 PM Report Abusive Post Report Copyright Violation | The problem is with a barrel of oil and how it breaks down. "On average, U.S. refineries produce, from a 42-gallon barrel of crude oil, about 19 to 20 gallons of motor gasoline, 11 to 12 gallons of distillate fuel, most of which is sold as diesel fuel, and 4 gallons of jet fuel." You still have to refine enough oil to keep the aeroplanes in the air. Lets say you replace the need for gasoline. That works out to the production of 39 Million barrels a day of waste byproduct called Gasoline. Even if you replaced 99% of a barrel of oil but still required 1% to sustain the global system. You would need the current global petroleum production system to obtain it. Last Edited by HYpEr7l93r on 12/14/2019 06:55 PM MlCHAEL |

Bi fuel gives you the ability to switch over after you run down the cng and are not near a refuelling station. We had a dedicated van in the 90s that had 14to1 pistons in it. Have not seen that since the 60s 70s when super high octane fuel was available. That thing had a 360 in it and ran like a raped ape but even with 3 to 4 tanks in it only got 150 to 175 range. With cng you can run higher compression engines. |

User ID: 78252253 Australia 12/14/2019 07:29 PM Report Abusive Post Report Copyright Violation | I have had multiple CNG and LPG cars over the last 30 years. Quoting: Toejamsoup CNG is gutless but cheap, LPG about 8o% power of petrol but half the price. I have T-boned a truck and had a head on collision on highway, both in CNG vehicles. No flaming fireball. Eventually you miss the power on CNG, no good on hills or for towing. LPG good for both but need to refill twice as much as petrol. . LPG 80% the power of petrol?! Got a Ford Territory with the Orbital LPG liquid Injections System. Uses 12 to 14 litres per hundred kilometres. It starts on petrol. If you floor it hard, it reverts to petrol. So here's the thing, when it runs on LPG, it feels almost v8 like, even though it's a Barra straight six/4 litre. If I could have it run LPG only, I would. Just paid .76c/litre this morning to fill it up. $46 was the cost. Last Edited by jonk on 12/14/2019 07:29 PM |

Anonymous Coward User ID: 73327673 Canada 12/14/2019 07:58 PM Report Abusive Post Report Copyright Violation | Sure, It works. Lots of the taxis in thailand have it. But, the ones that do have a great big tank in their trunk, so big that there really isn't any room for stuff in there. Keep in mind that a gallon of liquid NG or Propane doesn't have as much energy in it as a gallon of gasoline. Not by a long shot. There aren't many stations that can fill em up, and the ones that are out there always have a really long line and it takes a while. |

Quoting: Anonymous Coward 77327948 Actually, not. Engines running on gassified fuels are spotless on the inside, and have longer service intervals than their gasoline counterparts.. The engine runs very clean. Only problem with CNG, and I have a Ford F-150 bi-fuel CNG, is that the tank is only certified for 15 years. Now I have to buy regular fuel or purchase a new tank. It has been a wonderful truck which I have driven all over the western US. Sure you have to plan where you can get your next fill up but that is why you have it be bi-fuel.; if no service for CNG put regular in it. I have over 200,000 miles on it and the service guys are always impressed with how clean it is. |
Anonymous Coward User ID: 76811228 United States 12/14/2019 11:01 PM Report Abusive Post Report Copyright Violation | even better if it runs on Ammonia (less pressure and better millage)... Both are far better than hydrogen (think "Big bomb") Quoting: Anonymous Coward 76811228 Are you fucking high? Do you have any idea how dangerous anhydrous ammonia is???? A CNG tank going up would be bad for people within 100 yards, an ammonia tank rupturing would be a hazmat incident requiring the evacuation of everyone within a mile radius. I've personally been involved in an anhydrous ammonia leak, there were two routes out of the facility if I had taken the other one I would be dead right now. 3 firefighters out of the 10 who responded had to be hospitalized despite being decked out in full protective gear and SCBA masks... the shit can absorb through your skin. One guy at the facility also was hospitalized, and almost died. The tank that leaked wasn't even that big, I'd say it was about 3 or 4 times the size of an automotive fuel tank. And guess what you use to make ammonia? Natural gas!!! totally wrong about ammonia (it is in small tanks and dissipates quickly in open air) We are not talking about a 10,000 gallon Ammonia tank leaKING IN A building!! |

I have over 200,000 miles on it and the service guys are always impressed with how clean it is. Not sure if you can still buy the Dual Fuel vehicles, but 25 years ago a number of businesses and people did because they got HUGE tax credits for buying them since they qualified as "Clean Air" vehicles which effective cut their cost to buy by about 50% to 60% (in certain states). Knew a couple of people who bought 3/4 ton Suburbans and after the tax credits only had to actually pay about 50% of the out the door cost to buy them. Here about 1/2 of the city buses run on CNG. The fuel cost to run them is about 1/4 the cost to run them on diesel, so the mass transit authority LOVES them!, but they did have to open a couple of remote fueling stations away from their main garage location. UPS locally has switched about 80% of it's over the road tractors to CNG. For local delivery they still use gas/diesel vehicles, but for over the road I am told they are aiming for nearly 100% CNG for our major terminal here sometime in the next 2 years. I am noting more and more Interstate truck stops are also installing CNG fueling capability. Obviously the downside is the tank size/location, the problem with limited refueling (why you need a DUAL fuel option if you aren't running it in a fleet situation), and the up front purchase cost ... but if they are still available to buy there are some serious benefits (cheap fuel, longer engine life).

Standards Pre-Determine CNG Cylinder Life In the 1990s, the NGV industry created CNG cylinder certification standards. Cylinders built to meet the original (1992) version of Standard NGV2 were designed for a service life of 15 years, with labeling requirements setting a "Do not use after" date. A 1998 revision extended allowable cylinder life certification to 20 years. The 2007 revision raised that figure to allow a 25-year lifespan. [link to www.government-fleet.com (secure)] .
