The number of cars on the streets is increasing every day. People are choosing private over public transportation for the convenience it provides in terms of comfort, accessibility and flexibility. At a time when one can’t really do much about the number of cars on the streets, the best bet is to make sure that they don’t pollute the environment.
The use of Compressed Natural Gas is a great solution to this challenging situation. While purchasing natural gas engines, you should be aware of both its pros and cons.
Purchasing or shifting to natural gas engines from their gasoline or diesel counterparts might prove to be a hefty initial investment but the returns are significant. One can expect to save anywhere around 4000-5000 dollars every year by choosing natural gas. Apart from reduced costs for both individuals and businesses as incentives, other factors also make it a great choice for the overall good.
It is environment friendly, resulting in a 90% decrease in both nitrogen oxide and particulate matters when compared to diesel engines. Carbon dioxide emissions also reduce by 25%, helping combat global warming. It’s also safer because in case of a spill, natural gas will just dissipate into the environment while liquids like diesel will end up contaminating the water bodies. It’s safer even if your vehicle happens to collide because liquid fuel is flammable and dangerous in the event of a collision. Air and water pollution are not the only two things it helps combating. Noise pollution is also severely reduced with used of natural gas engines. They operate in a much quitter way than diesel engines.
A place like the U.S can greatly benefit from the use of natural gas engines because that would reduce their dependence on foreign countries for their oil needs as 90% of natural gas consumed in the U.S. is produced locally.
However, there are some possible disadvantages that you also be need to aware of before a purchase. Firstly, as mentioned before, vehicles with natural gas engines are considerably more expensive. Additionally, although natural gas itself might be a cheap and clean fuel, it necessarily does not give a great mileage. Moreover, it’s very difficult to calculate its fuel efficiency as it is measured in MPGe or Miles per Gallon equivalent. Last but not the least, unfortunately there aren’t many natural gas engine powered vehicles in the U.S. market right now to choose from.
Some manufacturers that lead in the manufacture of natural gas engines are Cummins, PACCAR, Navistar International, Clean Energy Fuels, Quantum Fuel Systems Technologies Worldwide and Westport Innovations.
