摘　　要：在低温条件下,柴油发动机存在运行状况不佳,主要表现为动力性低下、燃油经济性差、排放冒黑烟等特征。依据热力学原理,利用柴油发动机正常工作时循环系统的高温循环水,设计了一款燃油预热装置,使即将喷入发动机燃烧室的柴油预先与高温循环水进行热交换,并利用FC2000发动机测控系统,对柴油发动机燃油经济性进行台架试验,对燃油消耗量随温度变化特性进行试验研究,探求农用柴油发动机工作性能最佳时的燃油预热温度范围。Under low temperature conditions,the operation conditions of diesel engine is poor,mainly performed as low dynamic performance,poor fuel economy,the emission of black smoke.On the basis of thermodynamic principle,using high temperature circulating water of diesel engine cycle system in normal working conditions,through a fuel heating device to make it with the spray into the combustion chamber of diesel engine for heat exchange （fuel preheating） in advance,and use the FC2000 engine measurement and control system,to test bench of diesel engine fuel economy,the characteristics of fuel consumption changing with temperature were studied,the best diesel engine preheating temperature range of diesel engine on agriculture was explored.
