摘　　要：农用拖拉机负荷是影响其发动机工作性能的主要参数指标,直接影响拖拉机的田间工作效率及性能。相关研究表明:拖拉机发动机功率至少使用80%,且发动机转速较低时可以实现拖拉机高效运行。为此,对麦赛福格森-MF 8480的发动机在田间作物收获时的发动机负载参数进行了控制测试,构建相关数学模型反映发动机功率、发动机转速和燃料消耗特性之间的关系,并给出拖拉机运行期间不同发动机转速下的工作时间和油耗分布图,揭示了拖拉机田间运行效率及发动机各个参数运行关系。研究结果可为研究农用拖拉机发动机运行参数关系及提高田间运行效率提供理论依据及参考。Agricultural tractor load is the main parameter that affects the working performance of the tractor engine indicators,which directly affects the field efficiency and working performance of agricultural tractors.Relevant studies have shown that efficient tractor operation can be achieved when at least 80%of the tractor engine power is used and when the engine speed is low.In this study,the engine load parameters of Massey Ferguson MF 8480 were tested in a controlled manner during field crop harvesting.A mathematical model was constructed to reflect the relationship between engine power,engine speed and fuel consumption characteristics,giving the working time and fuel consumption distribution at different engine speeds during the operation of the agricultural tractor.The analysis of engine speed and load pattern reveals the relationship between tractor operating efficiency and the operation of each engine parameter in the field.The results of the study are intended to provide a theoretical basis and reference for the study of the relationship between the engine operating parameters of agricultural tractors and the improvement of field operating efficiency.
