INTERNAL COMBUSTION ENGINE Russian patent published in 1997 - IPC

FIELD: mechanical engineering; internal combustion engines; cleaning of exhaust gases. SUBSTANCE: engine has cylinder block 1 with cylinders 2 and manifolds. Catalytic converter is installed in exhaust manifold 4. Catalytic converter consists of housing which is also housing of exhaust manifold, one inlet hole and at least one outlet hole of reactor. Reactor housing accommodates oxidizing catalytic filter 17 made up of porous sections with oxide coating, for instance, copper oxide, and reducing catalytic filter 18 made up of porous sections with metal coating, for instance, copper. Exhaust manifold is provided with end face covers 8 and 8 which form spaces 22 and 23 uniting manifold and reactor spaces. Rotary gates 12, 13 designed for changing direction of gas flow are installed in end face spaces on walls of covers. EFFECT: improved quality of cleaning. 1 dwg
