The aim in this thesis is to provide a comparison of smoke levels among John Deere 6 Family four-cylinder tractors. The comparison group consisted of 5 tractors, each with a different year of production. The aim is to ascertain if the systems provided in new John Deere tractors show higher efficiency in reducing emissions than those in older tractors. Further, the thesis deals with particular substances emitted by compression ignition engines and their influence on humans and the environment. Furthermore, basic information is provided about European and US standards as well as ways to reduce to the minimum these harmful substance emissions from compression ignition engines to the atmosphere. Diagnostic instruments for measuring exhaust gas emissions from compression ignition engines are described. Further, the thesis contains characteristics of tractors in the study group and results of measurements, arranged in tables and in graphs. Lastly, the results are evaluated and conclusions are made for practice.
