The Impact of Powering an Engine with Fuels from Renewable Energy Sources including its Software Modification on a Drive Unit Performance Parameters

Abstract

The application of fuels from renewable energy sources for combustion engine powering involves a great demand for this kind of energy while its production infrastructure remains underdeveloped. The use of this kind of fuel is supposed to reduce the emission of greenhouse gases and the depletion of natural resources and to increase the share of renewable energy sources in total energy consumption and thus support sustainable development in Europe. This study presents the results of research on selected performance parameters of transport by internal combustion engines including: power, torque, the emission of sound generated by the engine, the content of exhaust components (oxygen O 2 , carbon monoxide CO, carbon dioxide CO 2 , nitrogen dioxide NO 2 ), and the content of particulate matter (PM) in exhaust emission. Three self-ignition engines were tested. The fuel injection controllers of the tested internal combustion engines were additionally adjusted by increasing the fuel dose and the load of air. The material used in the tests were mixtures of diesel oil and fatty acid methyl esters of different concentration. A statistical analysis was performed based of the results. The purpose of the work was to develop a resulting model for assessing the operation of engines fueled with biofuel and diesel mixtures while changing the vehicle's computer software. A computer simulation algorithm was also developed for the needs of the tests which was used to prognose the state of the test results for variable input parameters.

Analysis of modular transport systems functioning in selected European countries

“…This, however, does not meet the growing transport demand [3]. As the study shows, introduction of the EMS is associated with transport cost reduction, CO2 emission reduction [4][5][6][7][8] and decreasing the number of vehicles on the road [3,9].…”

Identification and analysis of factors influencing climate change in terms of CO2 emissions

“…In the EU 72.8% of the total emission of transport related harmful substances comes from passenger cars, whereas heavy vehicles account for 18.8% of emission. Assuming that 5.1mld [t] accounts for 100% of transport related CO2 emission, the global share of particular transport forms is as follows [16]:…”

Method of modelling operation and maintenance processes in public transport systems using a certain class of stochastic processes

“…Bus transport system operations involve many different costs including those involved in application of lubrication oils. In the case of relatively big bus combustion engines and a short time (coverage, service life) between successive oil changes this is a problem significant both in terms of economy and ecology [10][11][12][13][14]. Hence, many authors take up the subject of engine lubricants, the possibility of extending their operation time, and the models of transport means operation and maintenance processes often include the costs of lubrication oils as a separate cost category [1,[10][11].…”
