Patent number: 11168629Abstract: The present invention is one that accurately measures an exhaust gas component regardless of variation in atmospheric pressure around a test object that is a vehicle or part of it, and an exhaust gas analysis apparatus that measures component concentration in exhaust gas discharged from the test object that is the vehicle or part of it. The exhaust gas analysis apparatus includes: an exhaust gas detector that mixes the exhaust gas and reactive gas together and detects the resulting phenomenon; a pressure gauge that measures the atmospheric pressure at the time of measurement of the exhaust gas or pressure at a predetermined point inside the exhaust gas analysis apparatus as measured pressure; and a correction part that, on the basis of the measured pressure by the pressure gauge, corrects the measurement error of the exhaust gas detector associated with a variation in the supply amount of the reactive gas.Type: GrantFiled: September 9, 2019Date of Patent: November 9, 2021Assignee: HORIBA, LTD.Inventors: Naoto Mizutani, Masahiro Nishikawa, Haruhisa Mohara, Shun Fukami, Yosuke Kondo

Patent number: 10132785Abstract: In a gas analysis apparatus including analyzers that need ignition, such as FIDs, in order to make it possible to surely ignite the analyzers while downsizing the entire apparatus, the apparatus includes first and second analyzers to accept a sample gas, a first gas line provided with the first analyzer, a second gas line provided with the second analyzer and joined downstream of the first analyzer in the first gas line. At least one of the first analyzer and the second analyzer is configured to cause pressure fluctuations in the gas line including the analyzer when analyzing the sample gas. A first backflow prevention mechanism is disposed between another of the analyzers and a junction of the gas lines. The first backflow prevention mechanism is configured to prevent a fluid from flowing backward from the one of the analyzers through the junction toward the another of the analyzers.Type: GrantFiled: May 11, 2017Date of Patent: November 20, 2018Assignee: Horiba, Ltd.Inventors: Shun Fukami, Haruhisa Mohara, Shintaro Aoki

Patent number: 10101309Abstract: An exhaust gas analyzing apparatus of a vehicle mounted type equipped with an analyzer that is configured to analyze components contained in exhaust gas includes a sampling line that is an exhaust gas flow path extending from an exhaust gas introduction terminal that is configured to introduce the exhaust gas from the outside to the analyzer; a pressure reduction source that is configured to reduce a pressure in the sampling line to a predetermined pressure; and a temperature-regulating mechanism that is configured to regulate a temperature of the exhaust gas flowing in the sampling line to be at least a first temperature. The first temperature is set to be a temperature equal to or higher than an evaporation temperature of moisture at the reduced predetermined pressure and lower than an evaporation temperature of moisture at one atmospheric pressure.Type: GrantFiled: May 15, 2015Date of Patent: October 16, 2018Assignee: Horiba Ltd.Inventors: Shun Fukami, Shintaro Aoki, Toshio Ohta
