基于流量差法内燃机车随车油耗仪

The Study of the Oil Consumption Meter in Diesel Locomotives

文中介绍一专用于火车机车燃油消耗计量的仪器——内燃机车随车油耗仪,采用涡轮传感器测量流量,并用差值法对燃油消耗量进行积算。针对如何提高系统的测量精度,提出温度——体积误差修正方法。

The oil consumption meter in diesel locomotives in this paper is applied to measure the quantity of oil consumption of diesel locomotives. It uses turbine flow sensor to measure the oil flow, the cumulative quantity of the oil econsumption is computed by one flux subtracting another. The method of Temperature-Volume error correcting is used to improve the measurment precision.
