Transient emission and fuel consumption measurements on plant oil tractors

Abstract: The evaluation of environmental impacts of agricultural machinery requires realistic test methods for the exhaust emission measurements. On the engine test bed transient cycles with fast engine speed and torque changes are state of the art. Installed tractor engines were predominantly investigated stationary at constant speed and torque using an eddy current brake on the tractor PTO shaft. Repeatable, transient emission and consumption measurements on tractors can be performed by using an adapted test cycle based on the NRTC (non-road transient cycle). The averaging of the speed and torque values in 10 second intervals (10 s NRTC) allows the implementation of dynamic test cycles on the tractor test stand despite the higher moments of inertia compared to the engine test bench, even at cold start conditions. Besides emissions and consumption, exhaust gas aftertreatment systems and thermal management of the tractor systems can be analysed and optimized. In one of the trials the averag.... https://www.landtechnik-online.eu/landtechnik/article/view/56
