Abstract

The paper discusses the problem of exhaust emissions from farm machinery. The paper presents selected results of the measurements of exhaust emissions (CO, HC, NOx, PM) from farm machinery under actual operating conditions, during fieldwork. For the tests, the authors used a portable exhaust emissions analyzer (PEMS) for the measurement of gaseous exhaust emissions and for the measurement of the emissions of particulate matter. The analyzers provide an on-line measurement of the concentrations of the exhaust components under actual operating conditions. The tests performed under actual operating conditions provide invaluable information regarding the exhaust emissions. In the paper, the authors analyzed the relations between the engine operating parameters and the exhaust emissions. Despite differences in the methodology, the authors also presented a comparison of the obtained results with the currently applicable exhaust emission limits in order to draw attention to this issue.
