DEVICE FOR PROTECTION OF ATMOSPHERE AGAINST EXHAUST GASES OF ENGINE Russian patent published in 1997 - IPC

FIELD: manufacture of engines; protection of atmosphere against exhaust gases. SUBSTANCE: during operation of engine, exhaust gases are cleaned of CO₂ due to chemical reaction between gases and drops of alkali NaOH (KOH) in inner volume of filter-mixer. Then gases are freed of alkali entrapped by flow in separator and exhaust gases cleaned of CO₂ and alkali enter the engine. Oxygen added to gas flow before engine is obtained due to chemical reaction between peroxide of alkali metal, for example and water. Peroxide of alkali metal is stored in reactor bin. Gas check sensors and components of automatic control system ensure required amount of oxygen in gas fed to engine cylinder. EFFECT: enhanced efficiency. 2 cl, 1 dwg
