Comparative analysis of exhaust gases from MF285 and U650 tractors under field conditions CIGR Journal
Rashid, Gholami; Hekmat, Rabbani; Ali Nejat, Lorestani; Payam, Javadikia; Farzad, Jaliliantabar.
Agricultural machinery is an important source of emission of air pollutant in rural locations.  This work deals with the effects of types of tractors and operation conditions on engine emission.  The values of some exhaust gases (HC, CO, CO2, O2 and NO) from two common tractors (MF285 and U650) at three situations (use of ditcher, plowing and cultivator) were evaluated in the West of IRAN (Kermanshah).  In addition, engine oil temperature at operation conditions was measured.  Also results showed the values of exhaust HC and O2 of MF285 are lower than U650, while the other exhausts gases (CO, CO2, and NO) of MF285 are higher than U650.  Value of NO emission increased as engine oil temperature increased.  All of exhaust gases except CO have a significant...

PERFORMANCE AND EMISSION OF POLLUTANTS OF AN AGRICULTURAL ENGINE WITH TWO POWER TAKE-OFF SETTINGS REA
Schlosser,José F.; Farias,Marcelo S. de; Estrada,Javier S.; Santos,Gustavo O. dos; Gil,Emilio.
ABSTRACT Farming operations are usually performed implements driven by a power take-off (PTO) from tractors. Some manufacturers offer PTO settings named as economic (540E). Such configuration drives implements at lower tractor’s engine rotation, thus providing lower fuel consumption. An engine performance using standard (540) or 540E settings are different and poorly studied. The amounts of pollutants emitted by engines vary mainly with the applied load and rotation. The aim of this study was to compare the performance and exhaust emissions of a farming tractor engine under different PTO loads, using both standard (540) and 540E settings. Specific fuel consumption using 540E was an average 14.7% less than the standard setting. However, 540E promoted...
