20110120096 | PARTICULATE MATTER MEASUREMENT DEVICE - Disclosed is a particulate matter measurement device that continuously measures changes in a mass of PM contained in an exhaust gas under dynamic operating conditions, such as road travel, with a simple construction. The device dilutes and separates the flow of exhaust gas while an engine is operating. The particulate matters contained in one of the exhaust gas streams is collected by a collection filter to measure the mass and the remainder is measured by a mass-related value measurement means so that physical properties which indirectly indicate the mass of the particulate matters contained in the exhaust gas are continuously measured as time series change data. Then, time series change data for the mass of the particulate matter are found based on correlations of the individual measured data. With this configuration, the flow volume of the dilute exhaust gas that passes through the collection filter and the flow volume of the dilute exhaust gas that is introduced into the mass-related value measurement means are ensured by adjusting the flow volume of the diluting gas that dilutes the exhaust gas. | 05-26-2011 |

20130312482 | ANALYZER CALIBRATING SYSTEM AND EXHAUST GAS ANALYZING SYSTEM - An analyzer calibrating system intended to reduce calibration time and a consumption amount of calibration gas in the case of concurrently calibrating a plurality of analyzers and includes: a calibration gas line for concurrently supplying the same calibration gas to a plurality of analyzers; and a control unit adapted to determine whether or not an output value of each of the plurality of analyzers supplied with the same calibration gas is stable. The control unit calibrates the analyzer having the output value determined to be stable and stops the supply of the calibration gas to the analyzer having completed with the calibration. | 11-28-2013 |
20130317688 | TEST SYSTEM AND VEHICLE PERFORMANCE TEST SYSTEM - A device management apparatus has a display part that obtains various types of information outputted from testing devices, and erasably, switchably, or movably displays the pieces of information on a display, wherein regardless of the display of the pieces of information, the display part preferentially displays three alarm icons that are respectively for three pieces of alarm information including: sensitivity alarm information indicating a reduction in sensitivity of each of the testing devices; accumulated operating time alarm information that is alarm information on an accumulated operating time of the testing device; and inspection date/time alarm information that is information indicating approaching or passing of an inspection date/time of the testing device, and respectively have forms that are changed depending on contents indicated by the respective pieces of alarm information. | 11-28-2013 |
20130317689 | TEST SYSTEM - An administrating device that administrates a plurality of units for test used for a test of a mobile object such as a vehicle or a constituting component of the mobile object comprises a recognizing part that recognizes an assembly of one or more units for test as a group for test and an assembly of one or more group for test as a device for test, and an administrating body part that conducts a predetermined batch operation command or a predetermined batch setting for a unit for test that belongs to the designated one or more groups for test and/or that conducts a predetermined batch operation command or a predetermined batch setting on a unit for test that belongs to the designated one or more device for test. | 11-28-2013 |
20130333443 | HYDROGEN FLAME IONIZATION TYPE EXHAUST GAS ANALYZER - The present invention is intended to be able to determine an appropriate purge time in a hydrogen flame ionization type exhaust gas analyzer and a system incorporating the analyzer which includes: a collector electrode for capturing ions generated from exhaust gas by hydrogen flame; an acquisition circuit adapted to acquire ion current caused by the ions captured by the collector electrode; and an abnormality determining part for determining an abnormality in the case where a difference between a first output value of the acquisition circuit in the case where there flows no ion current caused by the exhaust gas to the collector electrode and a second output value of the acquisition circuit in the case where zero gas is introduced into the hydrogen flame is equal to a predetermined value. | 12-19-2013 |
20140345373 | FUEL CONSUMPTION MEASURING INSTRUMENT - An instrument that directly measures a flow rate and air-fuel ratio of exhaust gas, and from the flow rate and air-fuel ratio of the exhaust gas, calculates fuel consumption measures the fuel consumption at high response speed and with high accuracy. The instrument is provided with: an ultrasonic flowmeter | 11-27-2014 |
20150046101 | FUEL CONSUMPTION CALCULATION UNIT, FUEL CONSUMPTION MEASURING APPARATUS, AND EXHAUST GAS MEASURING APPARATUS - The present invention is intended to, at the time of directly measuring a flow rate of exhaust gas flowing through an exhaust gas flow path and an air-fuel ratio of the exhaust gas, and on the basis of the flow rate and air-fuel ratio of the exhaust gas, calculating fuel consumption, reduce a measurement error of the fuel consumption.
