Abstract

In the reduction of the content of pollutants in the exhaust gases of an internal combustion engine, by enriching the air-fuel mixt. by addn. of ozone in proportion reaching 200 mg/10000 l and more esp. 200-500 mg/l of the mixt., a chemical product is added capable of combining with nitrogen oxides produced during combustion to form a non-toxic product.
