Device for reproduction of clogging phenomenon of physicochemical post combustion line of thermal engine of car, has removable heat exchanger for cooling gas mixture heated at target temperature to allow formation of clogging deposit

摘要

The device has a gas flow circuit (60), and a power supply module (10) for supplying power to the circuit. The supply module creates a gas mixture representative of exhaust fumes from model molecules. A heater (20) heats the created gas mixture at predetermined target temperature. A removable heat exchanger (100) cools the gas mixture to allow formation of a clogging deposit. The supply module includes a flow regulator to introduce each model molecule from the gas mixture with predetermined mass flow. A flow injection module (31) is placed between the heater and the heat exchanger. Independent claims are also included for the following: (1) a computer program comprising program code instructions for controlling a clogging phenomenon reproduction device (2) a method for reproduction of physicochemical clogging phenomenon of physicochemical post combustion line of a thermal engine.
