Abstract

Discharge of harmful gases, eg. unburned hydrocarbons, CO, oxides of N and SO2 into the atmos., is prevented by treatment with steam in presence of a body contg. Ge or Ce. The harmful gases are esp. exhaust gases from an i.c. engine. The process can also be applied to turbine engines, turbo-reactors, domestic heating appliances and industrial flues. The engine power and fuel consumption are improved. The amts. of CO, unburned hydrocarbons, oxides of N and SO2 discharged are nil, compared with 4-5.5% CO and 1-3% of the other gases for an untreated engine. The engine operates easily on a lean combustion mixt., in contrast to an untreated engine. Treatment is esp. over an alloy or cpd. of Ge or Ge with a metal, e.g. Fe, contg. 0.5-100 (36-40)% Ce or 45-80% Ge. [DE2551350A1]
