Contributing to an environmentally friendly world with CNG Systems

CNG is a substitute for fossil fuels such as gasoline and diesel that is quickly growing in popularity. What makes it popular is that it falls under the category of alternative fuel solutions because it is more environmentally friendly by producing fewer greenhouse gases. Natural Gas has been used to fuel our households for many years but has yet to achieve standard use as a fuel for vehicles. CNG mainly consists of compressed methane gas, where the gas is compressed to less than 1% of the volume it occupies at standard atmospheric pressure. The United States is a leader in most cases, though worldwide, Pakistan has the highest number of vehicles running on CNG, with over 3600 CNG refueling stations. In vehicles, CNG can be used as the main or dedicated fuel source or as part of a bi-fuel system burning one fuel at a time. Manufacturers such as Fiat, Toyota, General Motors and Volkswagen currently sell bi-fuel vehicles. These engines can run on either gasoline from a tank or CNG from a separate high pressure cylinder. The driver selects which fuel to use by a flip of the switch on the dashboard.

Advantages

Because CNG burns up to four times cleaner than gasoline emitting far less Greenhouse [GHGs] gases like carbon monoxide and carbon dioxide, CNG vehicles have lower maintenance costs and offer a longer service life. Fleet operators have said reported reduced maintenance costs by 40% by converting their vehicles to CNG. CNG has a higher octane rating which, when used at a very high compression ratio in certain vehicles, will yield more power than a stock gasoline version. Natural Gas Vehicles [NGVs] experience less knocking and have superior starting and drivability. Another obvious benefit of natural gas is that it is 15%-50% cheaper per equivalent gallon than gasoline. Unlike fuels that are used in liquid form, in the event of a leak the gas which is lighter than air will dissipate into the air and avoid any possible chance of ignition or explosion.

Disadvantages

While it’s tempting to think of the reduced maintenance costs, the initial investment of incorporating CNG into your vehicle is quite costly. Converting vehicles to CNG systems ranges from $3000-$6000, depending on the type of vehicle. Those vehicles containing CNG systems require a greater amount of space for fuel storage resulting in less storage space available in a trunk of a car or the bed of a pick up truck. Also, possibly the greatest disadvantage is that CNG filling stations have limited availability that so this type of conversion proves to be more practical for those people living in areas with easy access to the stations.

Canada is one of the largest producers of natural gas in the world and so with this abundance; it makes it a very viable resource and an economic option for motor fuel. Like any other investment, a decision to convert to CNG should be based on solid information and a desire to sustain a healthy environment.
