Liquefied hydrocarbon gases, containing mostly the mixture of C3-C4 hydrocarbons, in many countries serve as an important source of energy, also for internal combustion engines. On a world scale, at present, about 270 million tonnes of this fuel is produced, of which motorization consumes 26 million tonnes (~10%). Poland is one of these countries, where LPG is a popular engine fuel. Annual consumption of so called autogas is about 1.7 million tonnes with increasing tendency. Almost 3 millions of cars with bifuel engines, mostly spark ignition ones, are driven on Polish roads. An extensive logistical infrastructure accompanies the development of the use of this type of fuel in Poland. There are numerous production companies in Poland working to meet the needs of this branch of industry, as well as a modern service base. Intensive research and development works in this field are carried out. The exceptional advantages of LPG as an alternative engine fuel have been highly appreciated in Poland. These advantages result mainly from the simplicity of its production. Relatively low investment costs and energy consumption are needed to produce high-quality fuel by degasolining of natural gas or crude oil stabilization. LPG is produced as a byproduct in numerous petroleum refining processes and its quality is relatively close to the engine fuel requirements. The source of aliphatic hydrocarbons falling into LPG range can also be the processes of biomass conversion and in the near future, fermentation processes. Environmental advantages of LPG are primarily very low emission of almost all toxic components of engine exhaust gases compared to gasoline or diesel fuel. In this chapter the results of research works aimed at the improvement of exploitation properties, logistics and LPG combustion processes in spark ignition engines are presented. In this area, anti-corrosion additives for LPG of very high effectiveness were obtained and tested. Also, with the help of additives, the problem of water separating from LPG during storage and transport in tankers has been solved. A multifunctional additive was obtained giving LPG adequate lubricity and detergent properties. The influence of water on the process of LPG combustion in a gasoline fuelled engine as well ways to supply water to the combustion zone are being studied. A mathematical model is being elaborated, precisely describing correlations between density and chemical composition of LPG as well as changes of density as a function of fuel temperature. In the realization of these plans LPG producing companies, research and development teams as well as producers of automobile LPG systems are involved. Successful completion of research works and design works will result in elimination of scarce disadvantages of LPG as an engine fuel, preserving at the same time all its numerous advantages as an alternative fuel for the future - the new era source of energy.

Abstract in PolishNiskie koszty wytwarzania, bardzo dobre spalanie, niska emisja toksycznych składników spalin, rozwinięta logistyka i wiele innych argumentów przemawia za stosowaniem LPG jako alternatywnego nośnika energii. Zalety skroplonych gazów węglowodorowych doceniane są szczególnie przez branżę motoryzacyjną. Na tle rosnącego stosowania LPG w świecie przedstawiono osiągnięcia polskiej branży autogazu w zakresie produkcji instalacji samochodowych, liczby samochodów wyposażonych w układy dwupaliwowe oraz infrastruktury logistycznej. Rozbudowie branży towarzyszy działalność badawczo – wdrożeniowa, prace projektowo – konstrukcyjne oraz promocja i marketing. W niniejszym artykule przedstawiono kilka wątków działalności innowacyjnej, której celem jest dalsze usprawnianie logistyki, pełniejsze wykorzystanie zalet LPG jako paliwa silnikowego oraz pośrednio – umocnienie pozytywnego wizerunku autogazu jako paliwa bardzo przyjaznego środowisku.
