    A used LNG Sterling daycab with the Cummins Westport ISL-G was driven from Whittier (Los Angeles) to Dallas (Salem) Nov 8 2016. Not having fueled an LNG truck before, the commercial driver obtained the attached instructions from CLEAN ENERGY and reviewed videos to learn what happens during fueling. This 2006 Sterling had the spark-ignited, Cummins Westport ISL-G engine (9 liter, it would seem.) This engine needs LNG at -195F to -207F @ 85-120 psig. The dealer has two others for sale.

    The truck traveled from TX to CA piggybacked to a diesel truck with three others. They are disconnected from each other by lifting the front of the frame with a chain and driving the other trucks out from under it. Before setting it down, the steering wheels are bolted on. The rear wheel brakes are returned to their operational position by backing off a long bolt on each side. In order to start the truck, the fuel valve on the tank was put in the open position. The vent valve is left closed.

    The route involved these stops:
    Groom (Amarillo) TX G & J Truck Sales http://gjtrucksales.com
    3989 South K St Tulare CA
    1262 E Madruga Rd Lathrop CA
    4305 W Capitol Ave West Sacramento CA
    275 S Peninger Rd Central Point OR
    200 W Oak St Lebanon OR LinnBenton Community College ADV TRANS TECH CENTER

    The 110 dge LNG tank had been loaded with fuel on the way in from TX. After inspection of all the fluids and lights, it was driven 60 miles from Whittier to Santa Clarita which is on the outskirts of Los Angeles to allow for easier traffic when leaving the next morning. After parking, the fuel valve was closed. During the night, the fuel gage went from 3/4 to 5/8 full. The next day, the fuel gage read empty for the last 50 miles of the 120 miles from Santa Clarita to Tulare.

    The first fueling involved practice venting the tank. Pressure was almost 200 psi on arrival, so the vent hose on the station dispenser was attached to allow the tank to be vented down to 100 psi by opening the vent valve and then shutting it. At this point, the dispenser automatically added LNG - it is VERY quiet. At 40 dge, the pressure was, again, over 150 psi so the dispenser shut off. Tank was vented again and the dispenser then put in another 40 dge.

    At Lathrop, the fuel and vent hoses were, again, attached to the tank. The vent valve on the truck tank was left open to see if this would work better and the fueling went uninterrupted. But it seemed to be taking on too much fuel as the dispenser reached 70, 80, 90. So, at 100 dge, the STOP button was pressed and all the hoses were disconnected and the vent valve shut.

    The next fueling at West Sacramento was done with the vent valve shut and proceeded well. 10 dge was added for the 60 miles just driven, so the truck seemed to be getting the expected 6 mpg. Because of recirculating the LNG from the station to the truck and back into the station - which must have been happening at the last fuel stop - the tank was very cold now. The next run would have to cover 315 miles to Oregon.

    Though there were active fuel sales showing at all the stations, the only other truck encountered was a tandem gravel hauler at West Sacramento. The driver had two LNG tanks which fueled through a single connection on the driver side of the truck. This connection point also displayed the pressure of each tank. These two dozen Peterbilt trucks operated by Chavez Transport in Dixon CA make three 150 mile round trips each day, fueling at the end of the day. The driver said using LNG has worked out well for the most part.

    After a night stay in Redding, the trip over the Siskiyou mountains was done the next day into Central Point Oregon. 45 dge was added which works out to 6.8 mpg. The truck was then driven to Linn-Benton CC Advanced Transportation Technology Center to be evaluated before being picked up by the customer.

    It seems a truck running on LNG can keep running long after the gages seem to show there is no fuel left, though the truck seller said to refuel when the tank reaches 1/4. With experience, the venting and hose handling is straight forward to figure out. Both VISA and VOYAGER cards were used. The LCNG station in Oregon was first filled with LNG (to supply a trucking firm using CNG) last August after Interstate in Tacoma and Kroger in Portland had received their fleets of LNG trucks several years ago. So this may have been the first LNG truck to make the 1000 mile trip on Interstate 5.

      Clean Energy responded that a number of LNG trucking firms are now plying Interstate 5 from San Diego to Seattle. This brochure includes seven locations for LNG that have become operational in the last six months in Fife WA , Central Point OR, Carson CA, Coachella CA, Perris CA, City of Industry CA, and San Diego CA:

        June 21 2017 - An LNG filling station in Belgium built for heavy trucks is being expanded to add a publicly accessible CNG filling station. In Europe, more than one million cars are already fueled by CNG, with Italy and Germany leading the way. Belgium is lagging behind in Europe, but the total number of CNG vehicles in that county will have more than doubled to almost 6,500 since early last year with 100 CNG stations coming online.
