LNG fuel is stored in the LNG tank. LNG is drawn out of the tank with a unique LNG pump, powered by hydraulic oil from a hydraulic pump. The LNG is then vaporized-using excess heat from the engine coolant-and exits the tank module at 100 ºF and 4,500 psi.
At the same time, a diesel fuel pump draws and pressurizes diesel fuel from the pilot diesel tank.

Both the diesel and natural gas are sent to the fuel conditioning module, where they are pressure regulated, filtered, and distributed to the fuel injectors via common fuel rails.
All Westport LNG system components are electronically governed by the control units, allowing continuous adjustments that provide optimal and unparalleled engine efficiency.
