Abstract

Tis paper provides an overview of possibilities for determining tractor’s engine load, fuel consumption and exhaust emissions in real operating conditions. Theuse of accumulated database in tractor’s electronic control modules for the analysis of engine load, fuel consumption and exhaust emissions is analysed. The methodology for analysis of engine power, speed and exhaust emissions’ dependencies, also for analysis of engine exhaust emissions is presented. Tis paper presents testing results of the unit combined of tractor “Massey Ferguson MF 6499” and drilling machine “Vaderstad Rapid” by engine load, fuel consumption and exhaust emissions. Drilling process time, engine load, fuel consumption and exhaust emission components’ distribution are presented in different engine speed and cyclic fuel injection modes. Test results are analysed separately for technological drilling and work processes at the headland. In the technological process of drilling, if the tractor engine speed and, correspondingly, the transmission gear ratio were reduced to get the set working speed, fuel consumption decreased, CO and CO2 emissions varied slightly, but the NOx increased significantly. Significant part of exhaust emissions occurred at headlands. The conclusion is that the fuel consumption and exhaust emissions, including harmful components, can be reduced only by complex optimization of technological processes and tractor operating modes.

Tractor’s engine efficiency and exhaust emissions’ research in drilling work consumption and environmental impact assessment today are obtained according to test data when the mode of engine is steady. Hansson et al (2003) and Lindgren et al (2011) have found that fuel efficiency increases proportionally with increasing the engine load. Lindgren et al (2010) studies have shown that emissions, when working with a mobile loader, significantly increased compared to the steadymode test results. Speed selection in field work has a great influence on the efficiency of work and engine load, as well as fuel consumption and exhaust emissions. In the works of tillage cultivation, tractor operation principle “Gear up, speed down” gives significantly reduced fuel consumption (Grisso, Pitman 2010; Grisso et al 2008). Emissions of CO, NOx and PM exhaust gases increased (Negoižescu, Tokar 2013; Li et al 2006)
