In parts 1 and 2 of the article, liquefied petroleum gas (lpg) is described as a mixture of hydrocarbon compounds of which propane (c3h8) and butane (c4h10) are the principal constituents. The development of lpg as a motor fuel is described and it is suggested that lpg may be regarded as a near-ideal internal combustion engine fuel, being normally complete burning, containing no contaminants such as lead or sulphur, and having an octane rating in excess of 100. The author refers to the marketing of lpg in the Republic of Ireland, and provides information on the use of the gas as an alternative to petrol as related to taxation and the numbers of retail stations throughout the country. Graphical illustrations are provided to assist a discussion on the suitability of lpg as a motor fuel in respect of fuel characteristics and ignition system requirements. Data are presented on ignition systems output and typical distributor advance curves. It is considered that despite the inherent power losses incurred when operating a petrol-tuned engine on lpg, there are a number of positive long-term advantages. These are summarised under the headings of combustion cleanliness, extended oil change periods, extended spark plug life, fuel pilfering and fuel cost saving. Lpg - petrol carburation systems are illustrated and described, and information provided on control equipment, gas storage tank fittings and connections. /TRRL/
