It was found that by using tractor specifications and data collected
in the ‘‘ECU Load Profile’’ histograms it is possible to conduct
monitoring on the engine performance and exhaust emission
parameters during operational period of the tractor.
Test results showed that in the ploughing process, the main
amount of fuel was consumed and CO2 emitted during technological
process of ploughing, and CO – during the work at headlands.
Large quantities of NOx are formed during the technological process
of ploughing, and also significant quantities – when working
at headlands (see Fig. 11). Technological process of ploughing
amounted to 74.8%, and work at headlands amounted to 25.2% of
total duration of the test. In the process of ploughing hourly fuel
consumption was 24.03 kg/h. Of these, 92.09% of fuel was consumed
for the technological work, and 7.91% – for the work at
headlands. Exhaust emission components in the technological
process of ploughing and in the work at headlands distributed as
