Publication number: 20180231410Abstract: In a conventional air flow meter, in the case of foreign matter having a large particle diameter, the inertia thereof is used as a measure to prevent contact with a detection element, but for foreign matter having a particle diameter of 10 ?m or less and an extremely small mass, the inertia thereof inside a bypass structure has almost no effect, and the foreign matter can adhere to the detection element. AC dust or the like defined by the SAE standard J726C in the U.S. being mainly cited an example of the abovementioned foreign matter having a particle diameter of 10 ?m or less and an extremely small mass, it is known that sand (dust) manufactured by refining Arizona desert sand is readily charged, and once dust having an extremely small particle diameter that has become electrostatically charged adheres to a detection element, the problem arises that the dust is difficult to eliminate, due to the Coulomb force thereof.Type: ApplicationFiled: November 18, 2015Publication date: August 16, 2018Inventors: Ryosuke DOI, Shinobu TASHIRO, Yasuo ONOSE, Noriyuki SAKUMA
