Why are natural gas vehicles better?Thank You!?
Compressed Natural Gas is the most common alternative fuel as many cities and governments have converted used it to power their diesel buses and trucks.
Advantages
Very easy on the engine, giving longer service life and lower maintenance costs.
Reduces the demand for finite petroleum supply
Reduces exhaust emission pollution
Improves fuel consumption and engine efficiency. When CNG and air in the right proportions are brought together, they mix thoroughly and rapidly, thereby improving the combustion efficiency, while the engine stays clean internally
Dry gaseous fuel does not dilute the lubricating oil, thus saving on oil filters and oil chargers
Disadvantages
Driving complaints due to loss of power with CNG. Dynamometer tests indicate that CNG-fuelled vehicles have 10-15% lower power output than petrol engines.
Increased exhaust-valve wear in CNG-operated vehicles are anticipated due to the drying effect of the gaseous fuel
Limited service availability
High cost of conversion
The additional weight of CNG cylinders does pose a problem
Countries who have more stringent regulations on exhaust gases would require retarding the timing even more and this would decrease power output and fuel efficaintcy.

Menendez, T. Boone Pickens and Hatch tout natural gas vehicle legislation
U.S. Senators Robert Menendez and Orrin Hatch are joined by T. Boone Pickens on July 8, 2009 to introduce new legislation that would help increase the use of natural gas vehicles

How can i convert my 1999 Honda Accord to CNG Natural Gas Vehicle?
I live in California. Can i convert to CNG Natural Gas Vehicle? or Only way is to sell my car and buy Honda Civic GX ?

Why not try propane,? Easier and cheaper.
What’s under the hood of a natural gas vehicle?
natural gas vehicles have horsepower, acceleration and carrying capacity similar to that of their diesel and gasoline counterparts, but there are big differences as well. In part four of our CNG Now! education series, we show you how CNG tanks can actually be safer than those used in gasoline-powered vehicles and how dedicated NGVs and bi-fuel vehicles can have a lower rate of maintenance and cost less to repair.

NEW, natural gas vehicles refuel in your home?
Anyone know you can buy a natural gas car and fuel your car at home?
Never need to drive to the gas station ever again.
Save money fuel at home using PHILL?

Did anyone see the Honda GX PDF.file on the Clean Site?
AND
The same car on the Honda Site?

Although cost was the main factor in switching over to cars that run on compressed natural gas, Sawicki was also swayed by the environmental benefits of the vehicles.
And in California, other benefits including tax credits and breaks allowing natural gas car drivers to drive in the carpool lanes, park in more convenient parking spaces and ride across the Golden Gate Bridge for free were also incentives for Sawicki.
Sawicki, whose Crown Victorias get about 300 to 325 miles to the tankful, fills up for about $1.62 a gallon at Fort Pierce Utilities. His two Crown Victorias, which were both originally sold at a surplus auction, and Ford Contour all run on natural gas. The only natural gas vehicle for sale to the general public that he knows of, he said, is a Honda Civic GX which sells for about $24,590.
It can be done, but it’s not particularly easy. http://www.ngvglobal.com/index.php?option=com_content&task=view&lang=en&id=341&Itemid=2 will give you the home refueling information.
The concept is simple, a small Home Refueling Appliance (HRA*), is fitted wherever a vehicle is parked for a reasonable period of time, a garage, carport or driveway at the home or workplace. The HRA is then connected permanently to the local natural gas and electricity supplies and provides fuel for the compressed natural gas (CNG) vehicle in the same manner as a refueling hose at a public station, pumping natural gas into the on-board CNG cylinder in the vehicle.
Where it differs slightly from normal refueling, is that the gas is pumped in over a longer period of time. The refueling time varies depending on how much fuel is already in the vehicle, but generally a complete fill is achieved within a four to twelve hour period. As most vehicles are stationary for at least this period of time each day, the extended refueling time has little or no effect on the usability of the vehicle.
Because vehicle owners park their car as part of their normal routine anyway, it takes less of their time to refuel than if they were to use a public refueling station, especially considering they don’t have to pay a cashier at the end of the process. The gas used is included in the vehicle owner’s regular monthly gas bills, simplifying the payment process and reducing costs at the same time. The extended fuelling time is actually the source of a major cost benefit as the equipment requirements are much simpler for ‘slow fills’ than for fast fills. (See below for more on costs).
There are of course safety standards that would be in effect since natural gas in dangerous to work with, and some cities I’m sure would either outlaw it or heavily regulate its use.
why is it better to use gasoline than natural gas for vehicles?
natural gas produce more energy but it is not recommended for climbing up into steep roads (ex. roads in the mountains). so the real question is, why is it that cars powered by natural gas is inappropriate for climbing up steep roads
You need a greater amount of fuel to climb. Gas can provide the amount of energy as it has more btu’s to it than the natural gas. It is just that it would require much much more natural gas to give you the same equivalent energy as gasoline. Your engine runs on a 13 to 14 part air to gasoline ratio.

Natural gas?
Does natural gas liquify when compressed, just as propane or butane does? If not that would make natural gas powered vehicles very impractical. Wouldn’t it?
Natural gas will not liquify until you reach extreme pressures somewhere in the 4 to 5000 range depending on temperatures. Propane & Butane liquify at around 175 depending on temperatures. The technology is out there to make LNG vehicles practical but making it safe to deal with the pressure is the big problem now.

Why is petroleum always the preferred fuel over natural gas in driving vehicles?
Natural gas, or methane if you prefer, is a much more volatile substance and is more costly to transport.
