THE "CLEAN AIR" BUS. A FURTHER REPORT ON THE OPERATION OF THE COUNTRY'S FIRST LPG POWERED BUS COVERING THE PERIOD OF OPERATION FROM 1ST APRIL 1974 TO 31ST MARCH 1976

The report is an account of the operational and mechanical problems associated with the liquefied propane gas powered bus. Also included in appendices are a road test report by commercial motor and weekly records of fuel and oil consumption over the period. Changes in the type of fluid flywheel fitted have improved vehicle performance but the fuel consumption remains high at an average of 3.5 miles per gallon. It was not possible to make direct comparisons of efficiency although the propane gas is cheaper than diesel oil. The power unit was very smooth and quiet in operation. Apart from the unexplained fracture of an oil pipe the system has been very reliable. The Rolls Royce B81 power unit mounted in a vertical, rear, transverse position has been shown to be reliable under urban operating conditions. Its acceleration is superior but its higher fuel consumption makes it uneconomical although it is hoped that the recent relaxation of fuel tax grant for propane powered vehicles will make it more competitive. /TRRL/
