Abstract
Abstract Method and apparatus for increasing the intensity of the secondary combustion of an internal combustion engine emission, by the injection of fresh air for the purpose of reducing the carbon monoxide content thereof, while simultaneously increasing the carbon dioxide content thereof, while lessening the polluting effects of the emission, and further in which emission heated air is introduced into the engine emission flow to further enhance the intensity of the secondary combustion reaction.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
136 words
In combination with an internal combustion engine having intake and exhaust manifolds, a turbo rotor connected to and driven by the exhaust gases from the exhaust manifold, means for charging fresh air into the turbo rotor for mixing with the exhaust gases, air intake means, a carburetor for mixing air received from the air intake means with fuel delivered to the carburetor, a first heat exchanger connected to exhaust gas from the turbo rotor for heating the air fuel mixture from the carburetor, a water-alcohol reservoir, a second heat exchanger connected to exhaust gas from the turbo rotor for heating the water-alcohol mixture from the water-alcohol reservoir, an air-fuel-vapor supercharger driven by the turbo rotor and mixing the heated carbureted air-fuel mixture and the vapor of the heated water-alcohol mixture before delivery to the intake manifold.
Claim 2
Dependent Claim
136 words
In combination with an internal combustion engine having intake and exhaust manifolds, a turbo rotor connected to and driven by the exhaust gases from the exhaust manifold, means for charging fresh air into the turbo rotor for mixing with the exhaust gases, air intake means, a carburetor for mixing air received from the air intake means with fuel delivered to the carburetor, a first heat exchanger connected to exhaust gas from the turbo rotor for heating the air fuel mixture from the carburetor, a water-alcohol reservoir, a second heat exchanger connected to exhaust gas from the turbo rotor for heating the water-alcohol mixture from the water-alcohol reservoir, an air-fuel-vapor supercharger driven by the turbo rotor and mixing the heated carbureted air-fuel mixture and the vapor of the heated water-alcohol mixture before delivery to the intake manifold.
Claim 3
Dependent Claim
37 words
The combination of claim 1, and further including: an electric generator driven by the turbo rotor, a hydrogen-oxygen generator driven by the electric generator for delivering hydrogen to the intake manifold and oxygen to the exhaust manifold.
