摘要
讨论了内燃机台架试验国家标准GB1105.1—1987应用于高原非增压柴油机有效功率修正时存在的问题,在此基础上提出了简单实用的修正公式,并对比了该公式对高原和平原非增压柴油机的修正结果.也把该修正结果和油耗线的核算结果以及ISO1585的修正结果进行了对比.该公式适合我国国情,无需标准状况的机械效率,可对任何海拔高度的试验机的任何工况点的有效功率进行即时修正.
The paper deals with the problems when the national diesel bench test standard GB1105.1-1987 is applied to correcting the brake power of naturally aspirated diesels at high altitude. Based on that, a simple and practical correction equation has been derived, and the results are compared of applying the new correction equation to naturally aspirated diesels at high and low altitude. Also, the results are compared with those from the fuel consumption line method and ISO1585 correction equation. In the final analysis, the new equation is suitable for application in China regardless of the mechanical efficiency and can correct the brake power of tested diesels in time in any condition and any altitude.
