富氧装置对柴油机高原性能的影响

Effects of Oxygen-rich Equipment on Diesel Engine Performance at Plateau

在内燃机高海拔（低气压）模拟试验台上,对F6L913柴油机进行了0 m和5000m海拔下的性能（动力性、经济性）模拟试验,以及5000m海拔下的柴油机加富氧装置性能模拟试验,分析高海拔和富氧装置对柴油机动力性和经济性的影响.试验结果表明,与0m海拔相比,5000m海拔下柴油机功率下降43.7％,燃油消耗率增加40％～60％;加装富氧装置后,与原机相比,5000m海拔下柴油机功率平均提升11.8％,燃油消耗率减小8.4％.

The performance of diesel engine F6L913 at 0 m and 5 000 m altitude was studied on the engine test bed for simulating high altitude（ low air pressure） , and the performance of the engine with oxygen - rich equipment was at 5 000 m alti- tude was tested. The results show that both power performance and fuel economy of the engine decreases at 5 000 m altitude, the power under different speeds decreases 43.7% on average and the rate of fuel consumption increases clearly. Oxygen - rich equipment can improve power performance of the diesel engine, with the help of Oxygen - rich equipment, the power advances 11.8% on average under different speeds at 5 000 m altitude, and it can also improve fuel economy of the diesel engine.
