Blackburn Council is to date the only legal operator of natural-gas powered vehicles in Great Britain. At present Blackburn has nine gas powered vehicles: two Freight-Rover 3.5-tonne tippers, two Freight Rover vans, and five Bedford Astra vans. These vehicles were converted from petrol-engined vehicles to dual-fuel vehicles. Stop-start and cold-start operations with gas show less engine wear, no sludge formation and no dilution of oil on cylinder bores, so oil-drain periods can be extended. Spark-plug life is estimated at 250,000 miles, and exhaust systems last indefinitely because of the cleaner emissions with negligible acids formation. A gas conversion kit can be transferred from vehicle to vehicle, the initial cost being in the region of 1,000 pounds Sterling. Ultimately, the whole-life cost, including fitting, seems likely to be well within 400 to 500 pounds Sterling per vehicle--cheaper than a catalytic converter.
