Opis:
Paper presents schematic description of the research covering production mechanism of Fatty Acid Ethyl Esters (FAEE) from waste vegetable and animal fats, which are creating a base for multi-component fuel BIOXDIESEL as well as results of physical, chemical analysis and results of engine and vehicles tests. The characteristic of wasted material used for production of fatty acid ethyl esters is showed. Cybernetic chain of biofuel BIOXDIESEL, system analysis and structure and scheme of the chemical reaction of Ethanol esterification of fatty acids is presented. Basic properties of exemplary BIOXDIESEL and Diesel fuel were compared. Caloric values of investigated BIOXDIESELS are shown. Mixtures of the BIOXDIESEL fuels with various composition have been tested and compared with Diesel fuel during engine tests on the engine test bench, vehicle test dyno and drive tests. The diesel engines of Fiat 1.3 Multijet, Mercedes300D, Landrover and ADCR compression ignition engine were tested with biofuels. Functional schema of the measurement set up is described. Cyclodynes obtained during testing of the ADCR engine fuelled with Diesel and BIOXDIESEL fuels with their centres of gravity are presented. Obtained and described results in the form of tables and graphs can be summarized with conclusions, that the performance of engines fuelled with BIOX-DIESELS is similar to engines fuelled with Diesel fuel.

Opis:
Dynamic combustion engine test stand allows a very accurate analysis of the engine work. The prototype of such a system was developed and built in a cooperation of Poznan University of Technology with the ODIUT Automex company. The system consists of an asynchronous motor controlled by a regenerative variable-frequency drive with an ability to return braking energy back to the power system. Together they permit to set very precise work points of the combustion engine in every time moment, unlike test stands with eddy current dynamometer, which are only able to brake the engine. Measuring system is used to gather data from all sensors, especially torque sensor, which records the torque on a drive shaft. Sensors are connected to electronic boards, which provide signal processing, and data acquisition. Fuel mass flow meter with temperature and pressure control allows regulating the parameters of fuel supplied to the engine. A set of applications is used for test stand management and data presentation and visualization. Real conditions and vehicle dynamics are emulated using advanced models to allow a comprehensive research of the combustion engine on the test stand. The paper covers the description of developed system, its components, software and models adapted in emulation. Moreover, it provides schematics of the system as well as a block diagram of the vehicle dynamic model.
