Abstract
Abstract An exhaust system for use with automobile engines and industrial plants for filtering exhaust emissions. An exhaust system comprises the exhaust pipe from the combustion chambers, the dehydrating filters and the cleaning device for the removal of detrimental matter from exhaust gases to protect the environment against pollution. The cleaning device includes the container with an inlet, an outlet and a vertical partition to separate the container into two chambers which contain the water solution of chemical substances to remove the detrimental matter from the exhaust gases. The cleaning device also includes the dehydrating filters. The exhaust gases passing through the water solution and dehydrating filters are caused to give up and deposit the hydrocarbons, the particulate material and to dissolve the pollutant gases, for example, the carbon dioxide and to form the carbonic acid.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
115 words
An exhaust system comprising an exhaust pipe from combustion chambers, dehydrating filters, a muffler, and a cleaning device for protection of the environment against pollution having a container with an inlet and an outlet of exhaust gases, said container comprising a vertical partition to separate said container into two chamber which contain a water solution of chemical substances to remove detrimental matter from exhaust gases; said cleaning device is arranged so that said exhaust gases are forced to pass through the water solution of the chemical substances in a first chamber, to detour the vertical partition in said water solution of the chemical substances and to pass into a second chamber before exiting said container.
Claim 2
Dependent Claim
115 words
An exhaust system comprising an exhaust pipe from combustion chambers, dehydrating filters, a muffler, and a cleaning device for protection of the environment against pollution having a container with an inlet and an outlet of exhaust gases, said container comprising a vertical partition to separate said container into two chamber which contain a water solution of chemical substances to remove detrimental matter from exhaust gases; said cleaning device is arranged so that said exhaust gases are forced to pass through the water solution of the chemical substances in a first chamber, to detour the vertical partition in said water solution of the chemical substances and to pass into a second chamber before exiting said container.
Claim 3
Dependent Claim
41 words
An exhaust system as defined in claim 1, said cleaning device comprising at least two dehydrating filters; said dehydrating filters are separated by means of the vertical partition and located over the level of the water solution of the chemical substances.
Claim 4
Dependent Claim
97 words
An exhaust system as defined in claim 1, wherein said cleaning device is designed so that said exhaust gases are forced to pass through said dehydrating filter in said first chamber of said container, to detour said vertical partition in the water solution of chemical substances and to pass through said dehydrating filter in said second chamber of said container; said exhaust gases passing through said water solution of chemical substances are caused to give up and deposit the hydrocarbons, the particulate material entrained in said exhaust gases, to dissolve carbon dioxide and to form carbonic acid.
Claim 5
Dependent Claim
42 words
An exhaust system as defined in claim 1, wherein said inlet of the container is connected with the exhaust pipe having an inlet for introducing compressed air into said exhaust pipe to transform carbon monoxide of said exhaust gases into carbon dioxide.
Claim 6
Dependent Claim
43 words
An exhaust system as defined in claim 1, wherein said outlet of the container is connected with said muffler by means fo the pipe having an inlet for introducing compressed air into said pipe to increase the speed of the exiting exhaust gases.
