FIELD: engines and pumps.
SUBSTANCE: stir plate may be positioned upstream of the oxygen concentration sensor in the exhaust pipe of the internal combustion engine, wherein oxygen concentration sensor is positioned in the exhaust pipe. The stir plate is designed to mix the exhaust gas flow in the exhaust pipe. The agitating plate is comprised of a first plate and a second plate. The first plate is comprised of a deflecting plate which runs in an oblique direction and a twisting direction relative to the direction of the exhaust pipe rout. The second plate runs in the direction perpendicular to the exhaust pipe rout. The second plate is comprised of a through hole. The second plate is positioned in the exhaust pipe on the outer circumferential side of the first plate.
EFFECT: higher efficiency.
