摘要
对拖拉机柴油机节油原理进行了较系统的分析,提出以燃油消耗率和单位行驶距离燃油消耗量作为判断拖拉机燃油经济性的依据。通过 JD3130型拖拉机柴油机的 PTO 性能试验,建立了扭矩—转速、小时耗油量—转速及柴油机最经济运转工况、最佳排烟工况等的数学模型,据此研制了以 MCS-51单片机为基础的拖拉机柴油机节油监控装置。
The principle of fuel efficiency is analyzed systematically.The fuel consump- tion per kWh and fuel consumption per kilometer are proposed as the criterions of trac- tor fuel efficiency.By testing the JD3130 tractor PTO performance,the mathematical models for engine torque-rotating speed,fuel consumption per hour-rotating speed are established.The optimum economic operating conditions and the operating conditions of optimum exhaust smoke are derived.A fuel efficiency monitor for tractor engine based on single chip microcomputer is developed.
