Abstract: A fuel property sensor is provided with three bypass passages and a measure passage. The measure passage is located inside of a closed loop which is comprised of common tangential lines of adjacent bypass passages and a part of profile line of each bypass passage in a cross section perpendicular to the measure passage. Even if the fuel property sensor is rotated around the axis of a fuel pipe in assembling the fuel property sensor to the fuel pipe, at least one of two bypass passages is always located above the measure passage in a vertical direction. Hence, bubbles included in the fuel are restricted from flowing into the measure passage. The fuel property sensor can detect the concentration of ethanol contained in the fuel with high accuracy.
Abstract translation: 燃料特性传感器设有三个旁路通道和测量通道。 测量通道位于闭环的内部，闭环由相邻旁路通道的公共切线和垂直于测量通道的横截面中的每个旁路通道的轮廓线的一部分组成。 即使燃料特性传感器在将燃料特性传感器组装到燃料管中时围绕燃料管的轴线旋转，两个旁路通道中的至少一个总是位于测量通道上方的垂直方向上。 因此，包含在燃料中的气泡被限制在流入测量通道内。 燃料特性传感器可以高精度地检测燃料中所含的乙醇的浓度。
