Opis:: Methyl alcohol is a cheap and potent adulterant of illicit liquors. Many outbreaks of methyl alcohol poisoning have occurred in our country. Such outbreaks have been responsible for a heavy toll of mortality and morbidity. This paper describes our clinical experience in managing patients with methyl alcohol poisoning, and emphasizes that early identification and prompt treatment is of prime importance. Methanol, also known as wood alcohol, is a commonly used organic solvent that, because of its toxicity, can cause metabolic acidosis, neurologic sequelae, and even death, when ingested. It is a constituent of many commercially available industrial solvents and of poorly adulterated alcoholic beverages. Methanol toxicity remains a common problem in many parts of the developing world, especially among members of lower socioeconomic classes (See Etiology and Pathophysiology and Presentation).

Opis:: In the paper are presented comparative tests of combustion of gasoline and combustion of methanol in spark ignition engine of the Fiat 1100 MPI type. The engine was equipped with a prototype suction manifold with duplex injectors on each cylinder. Implemented system enabled dual fuel operation of the engine with any fraction of the alcohol. Engine performance and start-up capabilities were the same like in case of the operation on gasoline only. Type and parameters of the fuel supply can be changed in any time during operation of the engine. The study dealt with comparison of a selected parameters used to assessment of combustion of the fuels: pressure of the working medium p, rate of pressure rise dp/d, heat release rate dQ/d, temperature of the working medium, and combustion angle. The investigations pointed at considerable differences in run of combustion of the gasoline and combustion of the methanol, as autonomous fuels. Moreover, addition of methanol to gasoline results in considerable differences in combustion process, comparing to combustion of gasoline mixtures. The combustion goes on more dynamically, especially during initial phase of the process, while total time of the combustion is shorter. Effects of these changes are: higher maximal pressures, faster rates of pressure growth and heat release. Extent of change of combustion parameters depends on methanol fraction in total dose of the fuel supplied to the engine. Addition of the methanol effects in growth of general efficiency of the engine, which increases together with growth of methanol fraction and engine load. Absolute growth of the efficiency amounted to 2-5%, while relative growth amounted to 6-16%. Such significant growth of the efficiency should lead to reduction of energy consumption during engine operation.

Opis:: In the paper are discussed test results of dual fuel spark ignition engine with multipoint injection of alcohol and gasoline in area of inlet valve. Engine fuelling was accomplished through a prototype fuel supply system comprising duplex injectors controlled electronically. Implemented system enables fuelling of the engine with pure gasoline, with pure methanol, or simultaneous combustion of the both fuels mixture with any fraction of the alcohol. The tests were performed on four cylinder, spark ignition engine of Fiat 1100 MPI type. In the paper are presented criteria to be fulfilled in dual fuel spark ignition engine run on gasoline and methyl alcohol. The criteria were developed on the base of engine testing performed on engine dynamometer. When developing the criteria, one took assumption of energetic equity of fuel doses in traditional and dual fuel supply system in every operational point of the engine. The second criterion consisted in maintaining a minimal elementary dose of gasoline and alcohol injectors, which would assure stable operation of the engine. In result of the performed analysis one proposed a map of possible ranges of dual fuel feeding of the engine with methyl alcohol and gasoline.
W artykule przedstawiono wyniki badań dwupaliwowego silnika o zapłonie iskrowym z wielopunktowym wtryskiem alkoholu i benzyny w okolice zaworu dolotowego. Zasilanie silnika realizowano przez prototypowy układ dolotowy zawierający podwójne wtryskiwacze sterowane elektronicznie. Zastosowany system umożliwia zasilanie silnika benzyną lub alkoholem oraz równoczesne spalanie mieszaniny obydwu paliw o dowolnym udziale alkoholu. Badania wykonano na 4-cylindrowym silniku o zapłonie iskrowym Fiat 1100 MPI. W artykule przedstawiono kryteria, jakie należy przyjmować przy stosowaniu dwupaliwowego zasilania silnika o zapłonie iskrowym przy używaniu benzyny i alkoholu metylowego. Kryteria opracowano na podstawie badań hamownianych silnika. Przy opracowaniu kryteriów przyjęto założenie równości energetycznej dawek paliwa z zasilaniem tradycyjnym i dwupaliwowym w każdym punkcie pracy silnika. Drugim kryterium było zachowanie minimalnej dawki jednostkowej wtryskiwacza benzyny i alkoholu, zapewniającej stabilną pracę silnika. W wyniku przeprowadzonej analizy zaproponowano mapę możliwych zakresów dwupaliwowego zasilania silnika alkoholem metylowym i benzyną.

Opis:: The article presents research results performed using automotive spark ignition engine run on methyl and ethyl alcohols as well as gasoline as a reference fuel. The research was performed on automotive engine of Fiat 1100 MPI type. The aim of the conducted analysis was to compare the operational parameters of the engine. These parameters included engine power output, overall efficiency, emissions of toxic components in exhaust gases, and a comparison of the combustion process course. This comparison was conducted based on recorded and averaged indicator diagrams, as well as individual combustion cycles. The averaged diagrams were used in analysis of the pressure course during combustion, in analysis of pressure growth rate and heat release rate. Diagrams of individual combustion served for assessment of operational smoothness of the engine when fuelled with alcohols. As the reference, parameters measured in case of gasoline fuelling were used.
