摘要： PROBLEM TO BE SOLVED: To provide a performance evaluation device capable of accurately simulating a temperature state of the emission gas at a cold start of an engine.SOLUTION: A performance evaluation device includes: a gas cell 1; a test gas feeding pipe 2; a test gas exhaust pipe 3; a cooling gas feeding pipe 4; a bypass pipe 5; and a heating furnace 7. The test gas exhaust pipe, the cooling gas feeding pipe, and the bypass pipe are provided with the first to the third valves 8 to 10. With the switching of opening/closing of the first to the third valves, before starting the test, a cooling gas flow is generated which reaches the bypass pipe via the gas cell from the cooling gas feeding pipe, and the interior of the gas cell is maintained at a low temperature. However, when the performance test is started, the feeding of the cooling gas is stopped and the test gas having a high temperature is fed to the gas cell. As a result, the test gas is generated which flows to the test gas exhaust pipe via the gas cell from the test gas feeding pipe. After that, the heating furnace is controlled based on the detection signal of a temperature sensor so that the temperature of a position of the temperature sensor 12 becomes a predetermined temperature setting value.

摘要： PROBLEM TO BE SOLVED: To mix a carbon powder or PM with a model gas continuously and quantitatively to evaluate the PM oxidizing activity of a catalyst in the model gas with high precision. SOLUTION: The evaluation gas supply device includes a powder supply means for supplying the carbon powder or PM into a standard gas continuously so as to set the same to a predetermined concentration to form a carbon mixture and a mixing means for mixing the carbon mixed gas with the model gas to form an evaluation gas. Since the carbon powder or PM is diluted in two stages, the evaluation gas containing a minute amount of the carbon powder or PM can be stably prepared with a high precision. The flocculation of the arbon powder or PM is supressed as compared with a case abruptly diluted to a low concentration to prepare the uniform evaluation gas. COPYRIGHT: (C)2005,JPO&NCIPI
