摘要
为了更好的适应柴油机配套要求,对柴油机进气冷却系统进行了整体方案设计,并对上壳体、散热器进行了设计计算,确定了稳压腔的容积、散热器的形状、尺寸等。进行了柴油机台架试验,对比了原机与采用进气冷却系统后柴油机的充气效率及在外特性试验条件下的整机综合性能,结果表明采用进气冷却系统后,柴油机最大功率可增加13k W,排气温度降低17℃,最低燃油消耗量降低5.3 g/k W·h。采用该进气冷却系统的柴油机可满足配套玉米收割机、大型拖拉机的需求,同时热负荷和燃油消耗量有所优化。
In order to better meet the matching requirements of diesel engine, the overall design of diesel engine inlet air cooling system is carried out, the upper shell and radiator are designed and calculated, and the volume of the regulator chamber and the shape and size of the radiator wait are determined. The diesel engine bench test is carried out, and the air charging efficiency and the overall performance of the original diesel engine and the diesel engine with the inlet air cooling system under the external characteristic test condition are compared. The results show that after using the inlet air cooling system, the maximum power of the diesel engine can be increased by 13 k W, the gas exhaust temperature can be reduced by 17℃ and the minimum fuel consumption can be reduced by 5.3 g/k W·h.The diesel engine with the inlet air cooling system can meet the needs of matching corn harvesters and large tractors, while the heat load and fuel consumption are optimized.
