摘　　要：分析了农用运输车现用冷却风扇驱动方式的缺点后，采用自控电动冷却风扇取代传统的冷却风扇，可使冷却风扇的工作效率提高至78％。驱动方式改进后，发动机可充分利用迎面风的冷却效果，缩短风扇工作时间，从而减少了发动机的功率消耗和散热损失，并可通过控制风扇的工作与否以缩短预热时间，使发动机保持在最佳温度范围内工作。The paper analyses the defect of the driving ways of rural transporter engine's ex isting cooling fan,compares it with a substituted automatic electrical motor fan, indicating the lat ter may raise its efficiency to 78%. The change of way of fan driving results in not only upgrading efficiency, but in reducing its work time as well. However,the improvement reduces engine power consumption and heat transfer loss,and then,makes it work at optimum temperature
