摘要： A flow rate of air flowing through an air inlet pipe is detected by a heating resistor disposed therein and converted into an electric signal. A digital processing unit carries out calculation to judge whether or not the converted signal coincides with a predetermined temperature value and to correct the converted signal so that the same is caused to coincide with the predetermined value if both the values do not coincide with each other. The corrected signal is used to keep the heating resistor at the predetermined temperature. The digital processing unit is integrated with the air inlet pipe independently of a digital processing unit for engine control.

摘要： An air flow rate measuring device for measuring intake air flow rate in an automotive engine, improved to reduce any error attributable to variation in the configurations of air cleaner and/or duct forming air passage upstream of the flow rate measuring device, thus offering high accuracy of the flow rate measurement. In one aspect of the invention, the inlet opening of a sub-air passage is disposed to contain the axis of a main air passage, while the outlet opening of the sub-air passage is disposed in the vicinity of a wall defining the main air passage. In order to cause a local reduction of the pressure of the principal of the air flow at the outlet opening, a protrusion or a flat surface which causes impediment to the flow if air in the main air passage is provided immediately upstream of the outlet opening. In another aspect, the inlet surface in which the inlet of the sub-air passage opens is stepped in the direction of flow of the air so as to enable air to be introduced into air flow rate measuring portion in the sub-air passage from different regions in the main air passage while giving a preselected order of preference to these different regions.
摘要翻译：一种用于测量汽车发动机中的进气流量的空气流量测量装置，其改进以减少由于流量测量装置上游空气滤清器和/或导管形成空气通道的结构变化引起的任何误差，从而提供高精度的流量测量。在本发明的一个方面，副空气通道的入口设置成容纳主空气通道的轴线，而副空气通道的出口设置在限定主空气的壁的附近通道。为了使出口开口处的空气流的本征压力局部地减小，突起或平坦表面在紧邻导出口的上游处设置有主空气通道中的空气，从而阻碍流动。另一方面，副空气通路的入口打开的入口表面沿着空气的流动方向是阶梯式的，从而能够使空气从不同的空气通道引入到副空气通道中的空气流量测量部分主空气通道中的区域，同时给予这些不同区域的预选顺序。
