Do you think green cars that runs with natural gas or petroleum gas are safe for our enviroment ?

Question

This cars are running now in latin american : fueled from natural gas or petroleum gas ...I wonder if this a safe solution for our enviroment...?

Answer 1

Yes. Modern cars run quite cleanly. Fuel injection helps engines burn fuel completely and efficiently. Better manufacturing keeps oil from burning in engines, and catalytic converters clean the exhaust. Diesel fuel used to be dirty, but new low-sulfur diesel is much cleaner. Modern petroleum cars hardly pollute, as long as they are working properly.

Natural gas is the cleanest fossil fuel there is. After processing, it is nearly pure methane, which burns cleanly to water and carbon dioxide. It burns so cleanly, cars that use it don't even need catalytic converters, and can actually clean smoggy urban air. Best of all, natural gas costs less than half as much as petroleum.

Both of those fuels are organic fossil fuels, and produce carbon dioxide when burned. CO2 is important to life on Earth and won't harm your immediate environment, but it is a greenhouse gas believed to cause global warming. However, compared to pollutants like sulfur dioxide, carbon monoxide or nitrogen oxides, I think carbon dioxide is of little immediate concern. (Besides, hybrids, clean diesels and natural gas cars are a logical next step toward electric, biodeisel, and hydrogen.)

I've read about some neat eco-cars produced in Central America. If those cars are like the ones you're talking about, Then I'd say they are perfectly safe for the environment. And as far as the color goes, every car looks good in green.

Answer 2

It's not as polluting, so it deserves some credit.

Answer 3

The trouble with methane is it is a far more serious greenhouse gas than CO2. and natural gas is also in decline world wide so prices are rising.

Answer 4

I own a pathfinder which I have had converted to run on petroleum gas (actually a mixture of propane and iso-butane). It emits about 20% less CO2 and only a fraction of the other polutants (Sulphur Oxides, NOXs, and sooth) of what vehicles running on gasoline and diesel emit. Though this is not a complete solution (a much higher reduction in CO2 emissions is needed) it is certainly a step in the right direction.

In Costa Rica, where I live, the fuel is readily available and costs about 40% less then gasoline does.
