【 摘 要 】

This paper presents the analysis of the base energy parameters and composition of exhaust gases for one-cylinder test diesel engine SB 3.1. fuelled by standard diesel fuel (DF) and Animal Fat Methyl Ester (AME). Animal Fat Methyl Ester (AME) is the result of using waste pork fat. A lot of publications analyze the use of fish fat methyl ester (CFME) and chicken fat methyl esters (CFME) but in Polish conditions we have a lot of pork fat waste. All of measurement was carried out on the some engine speed - 1600 rpm (speed of maximum engine torque) and various engine loads. Some of the analysed parameters were read directly from the laboratory measurement systems (e.g. fuel consumption) and the rest of them had been calculated (e.g. total efficiency of engine). Before the engine tests, the basic physical parameters of the used fuels were determined in the fuel laboratory: dynamic viscosity as a function of fuel temperature, distillation curve, combustion heat and calorific value. The calorific value of the used AMF fuel is 37,4 MJ/kg (42,6 MJ/kg for DF). As a result of the AME fuel viscosity analysis, it was found that in the fuel system of the internal combustion engine this fuel should be heated to the temperature 65°C. Hourly AMF fuel consumption is about 9% higher than for standard diesel fuel (DF). The overall efficiency of the engine, taking into account the calorific value of the fuel and the fuel heating energy, is lower by about 7% for the AMF-powered engine than for DF fuelled engine. In the case of an AMF-powered engine, a higher NOx concentration and a lower smoke opacity than for a DF-powered engine are obtained. For more accurate cause and effect analysis, the indicator diagrams and the rate of heat release in the cylinder of the combustion engine fuelled by the tested fuels (AMF and DF) were measured, which includes the second article: The influence of Animals Fat Methyl Ester (AME) on the indicator diagrams and heat release parameters in diesel engine cylinder.
