Opis:: The paper presents comparative analysis of operational parameters, smoke emission and toxic components contents in exhaust gases of a compression ignition engine fuelled with fossil diesel, commercial bio-diesel (fatty acid methyl ester) and their blend. Measurements were conducted on an older generation diesel engine equipped with in-line injection pump. Engine was operated in conditions of full load rotational speed characteristic and also ESC steady-state test cycle. Fourier Transform Infrared (FTIR) analytical system provided contents of 23 exhaust gas components. In particular chosen parameters of investigated fuels (on the base of quality reports), performance and fuel consumption characteristic versus rotational speed, smoke emission (D) and content of carbon monoxide (CO), unburned hydrocarbons (THC) and nitrogen oxides (NOx), sulphur dioxide (S02) and carbon dioxide (CO2) in exhaust gas of the engine fuelled with investigated fuels, emission of specific hydrocarbons of the engine fuelled with investigated fuels, of non-regulated compounds measured during the research, molar mass of analyzed exhaust compounds are presented in the paper.

Opis:: This paper investigated the impact of the exhaust gas recirculation on the concentration of selected harmful chemical compounds from the AVL 5402 research diesel engine powered with diesel fuel (DF) and compressed natural gas (CNG). The engine was operated in the dual fuel mode. It means that the engine was conventionally fuelled by regular diesel fuel and simultaneously by CNG dosed into the inlet pipe. The necessary tests were carried out for the mixtures containing 30, 50 and 70% of CNG (by energy content) in the total chemical energy delivered together with diesel fuel (DF) into the combustion chamber. The research was conducted for the stationary conditions of the engine operation at 1200 rpm and constant 1004 Joules of a fuel chemical energy delivered in each cycle into the combustion chamber. Under such conditions, the impact of the EGR rate changed in range of 0–50% on the emissions of selected unburned hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx) as well as particulate matter (PM), was evaluated. The obtained results confirmed that the EGR system is effective in the reduction of the NOx formation for all tested fuel mixtures. Nevertheless, it was found that the addition of CNG combusted in the diesel engine generates more harmful pollutants in comparison with diesel fuel. However, in some cases the concentration of NOx as well as PM was comparable or lower. It suggests that the combustion of CNG in diesels allows achieving environmental benefits. In this case, further optimization of the engine fuel supply system is necessary.

Opis:: The paper presents the research results of the AVL diesel engine powered with microemulsion fuels. In particular the emission of soot particles from the engine operated under stationary conditions was investigated. The necessary tests were carried out for two microemulsions containing 3.5 and 7% by volume of distilled water dispersed in diesel fuel with necessary surfactants/cosurfactants, i.e. Crillet-6/Span-20. Both tested microemulsions contained similar water micelles size distribution with average dimension of 18 nm. The results of the investigation confirmed that the combustion of tested water – fuel microemulsion in the AVL research engine reduces the emission of soot particles even by 50% in comparison with the diesel fuel.
