摘要： An exhaust gas analysis method comprises applying a laser beam to the exhaust gas discharged from an internal combustion engine, receiving the laser beam that has passed through the exhaust gas, and measuring the concentration of any of the components contained in the exhaust gas based on the received laser beam. The exhaust gas analysis method further comprises detecting the absorption spectrum of the laser beam absorbed in the exhaust gas by using the received laser beam (S1), calculating the concentration of the specific gas component by using the absorption spectrum (S2), calculating the temperature of the exhaust gas by using the absorption spectrum (S3), calculating the pressure of the exhaust gas by using the absorption spectrum (S4 to S6), correcting the calculated concentration of the component contained in the exhaust gas by using the calculated temperature (S7), correcting the concentration by using the calculated pressure (S8), and outputting the true concentration value (S9). Accordingly, the exhaust gas analysis method is substantially insensitive to variation in pressure and temperature of the exhaust gas and capable of calculating and analyzing the concentration of any of the components contained in the exhaust gas in an accurate, realtime manner.

摘要： A method for analyzing a temperature of exhaust gas includes calculating an approximate temperature at least one time by fitting a measured spectrum to a portion of theoretical spectra defined in association with a first temperature range using a temperature determined in the an immediately previous preceding temperature analysis as a reference, and then determining a calculated temperature by fitting the measured spectrum to all the theoretical spectra over a second temperature range that is narrower than the first temperature range, using the approximate temperature as a reference.

摘要： The present invention provides a radial turbine which uses a fluid having a plurality of pressures in a single turbine wheel, to thereby reduce the number of components and lower the cost. A radial turbine (100) includes a single radial turbine wheel (15) which converts, into rotational power, swirling energy of a swirling fluid with a first pressure that flows into the radial turbine wheel (15) from a main inlet (21) formed at an outer circumferential end through a nozzle (27) with a radial flow velocity component, wherein a sub inlet (29) is formed on an outer circumferential side of the radial turbine wheel (15) at a position radially and axially apart from the main inlet (21), and the low-boiling-point medium whose pressure decreases from the first pressure as the low-boiling-point medium travels to a radial inner side flows into the sub inlet (29) through a nozzle (35).
