ON BOARD INSTRUMENTATION TO AGRICULTURAL TRACTORS PERFOMANCE EVALUATING 2009-36-0379
This paper describes a project developed of a electronics instrumentation to obtain the needed data to compare the performance of differents agricultural tractors. A first system allows the measurement and recording of variables used in laboratory tests. The laboratory tests are made according to a technical standard used by agricultural tractors manufacturers. In this article, it will be presented the specific fuel consumption results for different characteristics and manufacturers tractors. In this case, this agricultural equipment were subjected to different working conditions in dynamometer tests. The performance of these vehicles also can be evaluated during a variety of agriculture business activities, such as transportation, preparation of soil, planting and harvesting. The second measurement system developed is an on board interface which allows registering the values of main physical parameters, needed to evaluate the performance of the tractor in field operation.
