The LNG technology uses natural gas as the primary fuel, along with a small amount of diesel as a combustible element to ignite the natural gas. Small quantities of diesel fuel and large quantities of natural gas are delivered at high pressure to the combustion chamber.
The LNG tractors utilize two 70-gallon LNG tanks and one 20-gallon diesel tank. The technology is preferable for heavy-duty applications compared to other fuels like compressed natural gas because LNG as a fuel is less cumbersome to transport. As a fuel, LNG is very dense, providing a large amount of energy for the amount of space it occupies. This makes LNG an excellent potential fuel for large trucks that need to travel a long distance before refueling.

UPS is working with the U.S. Department of Energy's Clean Cities program to advance LNGs in the marketplace. Launched in 2009, the program's objective is to encourage the reduction of foreign petroleum usage and reduce greenhouse emissions. Part of that mandate is improving America's investment in infrastructure. The program's support assisted in the purchase of LNGs and the construction of several fueling stations. The LNG corridor stretches from Ontario California to Nevada and Utah. UPS has an LNG fueling station in Ontario, California, which was built in 1997. In 2011, UPS deployed new LNGs to Clean Energy's Las Vegas fueling station.
