The Selection of an Energy-Saving Engine Mode Based on the Power Delivery and Fuel Consumption of a 95 kW Tractor during Rotary Tillage

The objective of this study was to estimate power delivery efficiency and fuel consumption based on engine modes. In study, a 95 kW power-shift tractor used analyze during rotary tillage. Rotary tillage conducted in field experiment with the conventional, APS (auto shift) power, ECO To conditions, soil hardness water content were measured, samples collected from experimental site texture by using USDA triangle. Finally, an efficient suitable mode selected for working load. It observed that tractive efficiencies when highest among other modes, accounting around 89.23 73.45%, respectively. However, approximately 23.02 L/h, which also comparatively higher than Additionally, each compared Brixius prediction model. statistical analysis predicted those tests showed there no significant differences modes; indicates controller could perform high accuracy. conventional mode, delivery, efficiency, 66.48%, 55.89%, 17.04 respectively, low. slip ratio 18.80%, On hand, PDE, TE, 77.57%, 58.44%, 19.39 but lower mode. Furthermore, comparative loads located ungoverned region very close engine’s maximum torque, allow sudden unwanted turn-off due fluctuations loads, is be avoided. modes governed region, outside operating range. Therefore, we recommend users operate tractors tillage, considering economics loads.
