CNG Trucks - Alternative Fuel Choice

 

CNG logoCompressed Natural Gas (CNG) is a fossil fuel substitute for gasoline (petrol), diesel, or propane fuel.



Although its combustion does produce greenhouse gases, it is a more environmentally clean alternative to those fuels, and it is much safer than other fuels in the event of a spill (natural gas is lighter than air, and disperses quickly when released). CNG may also be mixed with biogas, produced from landfills or wastewater, which doesn't increase the concentration of carbon in the atmosphere.



CNG is made by compressing natural gas (which is mainly composed of methane [CH4]), to less than 1% of its volume at standard atmospheric pressure. It is stored and distributed in hard containers, at a normal pressure of 200–248 bar (2900–3600 psi), usually in cylindrical or spherical shapes.



CNG is used in traditional gasoline internal combustion engines that have been converted into bi-fuel vehicles (gasoline/CNG). In response to high fuel prices and environmental concerns, CNG is now being used in pickup trucks, medium and heavy duty trucks and more.

 

CNG compared to LNG

CNG is often confused with liquefied natural gas (LNG). While both are stored forms of natural gas, the key difference is that CNG is gas that is stored (as a gas) at high pressure, while LNG is in uncompressed liquid form. CNG has a lower cost of production and storage compared to LNG as it does not require an expensive cooling process and cryogenic tanks. CNG requires a much larger volume to store the same mass of gasoline or petrol and the use of very high pressures (3000 to 4000 psi, or 205 to 275 bar).



We offer CNG alternative fuel trucks for all of our brands.
