在实际使用中,燃油超耗问题,往往忽视。因此造成能源浪费,增加使用成本,降低动力性能。拖拉机和农用运输车等农村柴油动力机械,如油耗超过正常耗油量的15％以上,则说明发动机出现了燃油超耗的故障。燃油超耗由多方面引起的,主要原因及其排除方法如下: (1) 供油量过大。这一故障会使发动机耗油量较正常情况显著增加,机温异常增高,积炭和冒浓烟严重,发动机工作不良,动力性能变坏等。排除方法:应检修高压油泵,并在油泵试验台上重新调整正常的供油值;检查喷油器雾化质量和 In actual use, fuel consumption problems are often overlooked. As a result, energy is wasted, costs are increased, and power performance is reduced. Tractors and agricultural vehicles such as rural diesel powered machines, such as fuel consumption more than 15% of normal fuel consumption, then the engine fuel consumption over the failure. Fuel consumption caused by many aspects, the main reason and its removal method is as follows: (1) the fuel supply is too large. This failure will make the engine fuel consumption significantly increased compared with normal conditions, abnormal temperature increased, carbon deposition and smoke serious, poor engine performance, power performance deterioration. Remedy: High pressure oil pump should be overhaul, and in the pump test bench to re-adjust the normal value of fuel; check the atomizer spray quality and
