摘要
TY1151流量变送器属于差压式流量计范畴的一种,它在内燃机空气测量中存在一定的误差。充气效率是内燃机一个重要性能指标。以480Q柴油发动机上应用TY1151差压式流量变送器测量充气效率为例,初步探讨了造成误差的主要因素及改进办法。
There exists distinct error in measuring the internal combustion engine air with TY1151 current capacity transmitting instrument,a type of pressure differential capacity transmitting measurement.Capacity efficiency is an important performance index of internal combustion engine.The paper discusses the major cause of the error with the example of TY1151 current capacity transmitting instrument applied in the 480Q Diesel Engine.
