ASSESSMENT OF THE ROLE OF THE LIQUEFIED PETROLEUM GAS (LPG) ENGINE IN STAGE CARRIAGE SERVICES VEHICLES

An assessment has been made into the viability of replacing the usual diesel engine in a stage carriage service vehicle (bus) with a spark ignition engine designed to operate on liquefied petroleum gas (LPG). The advantages of the LPG engine are less smoke, less noise, less odour, greater power for acceleration and less first cost. The disadvantages are an increased fuel consumption in terms of miles per gallon and slightly higher emissions of carbon monoxide and unburnt hydrocarbons. The former may be allevated however if the cost of LPG to the consumer is proportionately less than that of diesel fuel. In this the excise duty and rebate system is very important. The availability of LPG is good at present and is expected to increase over the next ten years. /Author/TRRL/
