Title:
VEHICLE-MOUNTED DRAIN SEPARATOR, AND VEHICLE-MOUNTED EXHAUST GAS ANALYSIS DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/218795
Kind Code:
A1
Abstract:
A vehicle-mounted drain separator 100 used in a vehicle-mounted exhaust gas analysis device 200, the vehicle-mounted drain separator 100 comprising: an exhaust gas flow path EL through which exhaust gas flows; and a dilution air flow path AL through which air drawn in from the exterior in order to dilute the exhaust gas flows, the dilution air flow path AL converging with the exhaust gas flow path EL at a convergence point CP provided at a downstream end section. The vehicle-mounted drain separator 100 is configured such that heat exchange is performed between the exhaust gas flowing through the exhaust gas flow path EL and the air flowing through the dilution air flow path AL at least at a location upstream from the convergence point CP.
