Prins VSI-2 Bi-Fuel Kits for Sky Harbor Parking Shuttles
Blue Star Gas reports the conversion of three shuttle buses operated by PreFlight Airport Parking to propane-gasoline bi-fuel operation at Sky Harbor International Airport in Phoenix.
“The company first converted three of its Ford E-450 shuttles to propane autogas bi-fuel systems in 2016,” states a release.
“Three more of the vehicles, which can use either propane autogas or gasoline at the flip of a switch, will be converted by early summer, with the goal to eventually convert all 14 shuttles used at Sky Harbor International Airport.”
‘Much Simpler than the CNG’
Blue Star used Prins VSI-2 kits on PreFlight’s Ford E-450 vehicles.
“The propane system is much simpler than the CNG [compressed natural gas] system, so our own in-house mechanic can do most of the repair work himself,” PreFlight market officer John Walsh says in the Blue Star announcement.
“With diesel, we were having too many mechanical issues around the pollution control systems,” Walsh said. “They were not designed for the type of driving we do which is low-speed, just to and from the airport,” Walsh said.
‘Attractive’ Fuel Price
“CNG – which we have at several locations – is a lot more expensive and a lot more complicated to service.”
As for propane autogas, said Walsh, “The price of the fuel was also attractive.”
