Abstract
Abstract The exhaust gases from an internal combustion engine which is using gasoline and air as fuel, are passed through a catalytic condenser for converting and/or condensing the products of combustion into various liquids and solids which are removed from the condenser, with the remaining and/or newly formed gases being recycled to the cylinders of the engine for further combustion and/or conversion. The system is operable fully closed with no gaseous exhaust to the atmosphere, with the solids from the condenser being removed by means of a filter, and with the liquids being received in a storage tank.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
155 words
An internal combustion engine system including: an internal combustion engine assembly containing first and second banks of combustion chambers; first and second inlet means in controlled communication with the first and second banks of combustion chambers, respectively; first and second outlet means in communication with the first and second banks of combustion chambers, respectively; a condenser housing having a gas inlet, a gas outlet, and a liquid outlet; cooling means in the condenser housing; baffle means in the condenser housing; means in the condenser housing for directing fluid onto said baffle means; means for introducing an air/fuel mixture into the first inlet means of the first bank of combustion chambers; exhaust passage means interconnecting the first and second outlet means of the combustion chambers with the gas inlet of the condenser housing; and return passage means interconnecting the gas outlet of the condenser housing with the first and second inlet means of the combustion chambers.
Claim 2
Dependent Claim
155 words
An internal combustion engine system including: an internal combustion engine assembly containing first and second banks of combustion chambers; first and second inlet means in controlled communication with the first and second banks of combustion chambers, respectively; first and second outlet means in communication with the first and second banks of combustion chambers, respectively; a condenser housing having a gas inlet, a gas outlet, and a liquid outlet; cooling means in the condenser housing; baffle means in the condenser housing; means in the condenser housing for directing fluid onto said baffle means; means for introducing an air/fuel mixture into the first inlet means of the first bank of combustion chambers; exhaust passage means interconnecting the first and second outlet means of the combustion chambers with the gas inlet of the condenser housing; and return passage means interconnecting the gas outlet of the condenser housing with the first and second inlet means of the combustion chambers.
Claim 3
Dependent Claim
43 words
An internal combustion engine system as set forth in claim 1, which further includes valve means in the return passage means to the inlet means of the combustion chambers, for modulating the amounts of gaseS which are returned to each bank of cylinders.

Claim 10
Dependent Claim
35 words
An internal combustion engine system as set forthe in claim 7, which further includes filter means in the passage means interconnecting the liquid outlet of the condenser housing with the inlet of the storage tank.
Claim 11
Dependent Claim
30 words
An internal combustion engine system as set forth in claim 1, which further includes means for introducing oxygen into the first inlet means of the first bank of combustion chambers.
Claim 12
Dependent Claim
37 words
