EXHAUST GAS SAMPLING APPARATUS, EXHAUST GAS ANALYSIS SYSTEM, EXHAUST GAS SAMPLING METHOD, AND EXHAUST GAS SAMPLING PROGRAM

摘要

To provide an exhaust gas analysis system that can accurately analyze exhaust gas discharged from an engine of a hybrid vehicle and can also be applied to a test that continues sampling into a sampling bag over a predetermined sampling time, a sampling apparatus is adapted to include a main flow path through which the exhaust gas flows, a sampling flow path that is connected to the main flow path to sample the exhaust gas into a sampling bag, and a constant flow rate mechanism that is provided in the main flow path and configured to be able to change a main flow rate that is an exhaust gas flow rate through the main flow path. Additionally, a control device is adapted to control the constant flow rate mechanism to change the main flow rate and change a sampling flow rate that is an exhaust gas flow rate through the sampling flow path.
