[en] In this paper, a Non Linear Programming (NLP) model is developed to establish the amount of ethanol produced in Brazilian distilleries to compose shares for exportation to be used as renewable automotive fuel, blended with gasoline. The model takes into account the minimization of the global annual cost of production, considering the specifications required by the importing countries. The ethanol properties are converted on a volumetric basis to achieve the blend properties. The global optimization solver Baron, available in GAMS, was used to solve the problem. A case study was considered to test the applicability of the model and results show the global optimum

[en] Petro-Canada's views regarding energy deregulation were presented. Their experience with gasoline retailing and their response to competition was also discussed. Petro-Canada regards deregulation as a good thing in terms of its promotion of fair competition. Industrial and residential consumers of energy will benefit from more efficient and innovative service. Today's consumers are very well informed about existing energy products and while they are incredibly price sensitive, they still want to buy value. The relevance of brand names in a competitive market was examined. One reaction to the demanding customer has been to augment the base product (the fuel) with other things, such as convenience store items, car washes, specialized bay businesses and promotional offerings. Petro-Canada has been successful in improving sales volumes with these sales strategies, and profits achieved indicate good target audience acceptance. Shareholders and the board of directors also appear to be in agreement with the Corporation's performance to date

[en] Two events at the 16th World Energy Congress focussed on the subject of mobility, which is a determining factor of worldwide mineral oil consumption. The study 'Global transport sector energy demand towards 2020', written by a working group led by the Norwegian Statoil company, served as a basis for the debates. (orig.)

[en] Opportunities for expanding the propane market in North America are discussed. The goal of change should be to enhance client satisfaction and loyalty. The current customer base is largely comprised of pick-up trucks, vans and buses in commercial fleet service, police and similar fleet service and privately owned vehicles. Opportunities for the expansion of propane exist due to: vehicles being kept and lasting longer, allowing a longer pay-back time; exhaust emission standards becoming more stringent; the possible introduction of emission standards for substances currently not controlled; and properly combusted CO₂ emissions that are at least 12% lower than gasoline. The continuing development of engine fuel management systems, application of extensive road/highway experience, matching supply and refuelling infrastructure to consumer demands, application in air quality non-attainment areas, and original equipment manufacturer, government and industry cooperation are discussed. 8 figs

[en] A directory of companies engaged in automotive propane conversion in Alberta and British Columbia is provided. There are a total of eight entries : three in Calgary, one in Edmonton in Alberta and two in Burnaby, one in Dawson Creek and one in Fort St. John in British Columbia. Each entry provides information about the company, including name, address, phone and fax numbers, owner's or manager's name, conversion equipment brands used, number of bays, type of retail sales and accreditation

[en] Rational self-interest and good environmental citizenship are forcing the development of renewable and environmentally, acceptable working fluids. Fluids that are at least equivalent in performance plus biodegradable have been formulated in Europe and USA rising vegetable oils as base stocks and as innovative additive packages. While much of the research has been made in the field of alternative environmentally, friendly energy, transport media, the thermal stability of vegetable based stock is still a challenging area. This work concentrates more in improving the oxidation stability of the vegetable based stocks. Oven and oil bath test methods were employed in this study. This paper tabled mineral and vegetable oil physical test results and presents thermal stability of oil blends. (Author)

[en] This study is focused on the province-wide emissions in Ontario, Canada and urban air pollution in the city of Toronto. The life-cycle impacts of utilizing alternative fuels for transportation purposes is considered in terms of six major stressors for climate change, acidification and urban air quality. The two types of vehicle considered are plug-in hybrid electric vehicles and fuel cell vehicles. Modeling of the penetration rates for both types of vehicles has been completed based on the maximum capacity of the electrical grid including planned improvements. Results show that the reduction in greenhouse gas emissions from adoption of either vehicle type will exceed 3% of the current emissions from the transportation sector in Ontario. Both vehicles exhibit similar impacts on the precursors for photochemical smog although the province-wide effects differ significantly. (author)

[en] A summary of publicly available data on the propane industry in Canada was presented. The main sources of data are the National Energy Board, Statistics Canada and Natural Resources Canada. The paper is divided into the five sections: the industry, production (supply), demand, prices, and comparison of propane to other fuels. Some of the topics discussed within these five sections were transportation of propane, propane use as a petrochemical feedstock, industrial energy demand, energy demand for motor fuels, residential energy demand, and accidents resulting from propane use. The report states that propane for road transportation and urban transit has risen from 13.9 per cent of domestic propane demand in 1984 to 23 per cent in 1996. At the present time, auto propane sales are declining as a direct result of the declining number of propane conversions below fleet replacement levels. The suspected reason for the decline is that propane conversion equipment technology has not kept pace with changes and improvements in gasoline engine technology. Some preliminary data on propane related accidents is also reported. 13 refs., 9 tabs., 18 figs

[en] This paper estimates the trends of fleet car fuel efficiency and new car fuel efficiency in Great Britain and analyses determining factors of the changes in car fuel efficiency. According to the analysis results, the pure technology effect was partly offset by the increase of average engine capacity of vehicles, especially since the late 1980s. Although in the 1990s, the pure technology effect itself was much reduced than in the earlier period, the shift in consumer choice to bigger cars also obstructed the improvement of fuel efficiency in this period. Meanwhile, this study found about a 10% gap between the official fuel consumption rate of new cars and on road fuel consumption rate, which generally confirms the result of earlier studies

[en] A directory of auto propane dealers in Alberta, British Columbia and Manitoba was presented. Dealers in Calgary, Edmonton, Burnaby, Dawson Creek and Winnipeg were listed along with their addresses, phone numbers, fax, and E-mail addresses. Some of the other information provided included accreditation, equipment used and manufacturer brands used by the dealers
