EXHAUST SYSTEM FOR WASTE GASES WITH DEVICE FOR PROCESSING WASTE GASES AND HEAT EXCHANGER IN PIPELINE OF EXHAUST GAS RECIRCULATION (VERSIONS)

摘要

FIELD: heating.;SUBSTANCE: system (1) of exhaust waste gases (WG) appearing in work of internal combustion engine (2) includes intake system (3) and an exhaust pipe (4), which are interconnected with a pipeline (5) of WG recirculation with the device (6) placed in it for processing WG and a heat exchanger (7). The heat exchanger (7) creates the first dynamic pressure, and the device (6) for processing WG creates a second dynamic pressure, which is less in size than the first dynamic pressure. Device (6) for processing WG is located along the exhaust stream of WG prior to the heat exchanger (7) at the first distance (8) from it. Device (6) for processing WG contains a cell element (17), and in the working process of the system cumulating of effects of creation of the first dynamic pressure and the second dynamic pressure takes place which is provided by the influence of the first dynamic pressure created by the heat exchanger (7) the second dynamic pressure generated along the stream of WG prior to the device (6) for processing WG, with giving the motion of the WG flow (14) entering the device (6) for processing WG, of uniform character regarding to passage of this flow through the device for processing WG.;EFFECT: reduction of pollution of the heat exchanger at the lowest possible dimensions of the heat exchanger and catalytic converter.;13 cl, 4 dwg
