Abstract
Abstract An apparatus is disclosed for adapting an internal combustion engine for operation on compressed air. The apparatus includes a source of compressed air, valving means for introducing the correct amount of air into the cylinders and valve actuation means to cause timed opening of the valve means for introducing compressed air to the appropriate cylinders at the correct time. The apparatus is constructed so that it can be readily mounted on or removed from the engine thereby allowing portability from one engine to another or conversion of the engine back to operation on a combustible fuel.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
142 words
Apparatus removably adaptable to an internal combustion engine having at least one cylinder containing a piston reciprocable therein, an intake valve, an exhaust valve and a hole for reception of a spark plug, said apparatus comprising a source of compressed, non-combustible gas, valving means including a manifold and at least one gas distribution valve, said gaS distribution valve being connected to said cylinder at said hole and to said manifold, said manifold also being connected to said source of compressed gas, and valve actuation means connected to said gas distribution valve, said gas distribution valve upon actuation by said valve actuation means permitting introduction of said compressed gas through said spark plug hole from said manifold into said cylinder when said intake and exhaust valves are closed and said piston is in a position to provide a power stroke in said engine.
Claim 2
Dependent Claim
142 words
Apparatus removably adaptable to an internal combustion engine having at least one cylinder containing a piston reciprocable therein, an intake valve, an exhaust valve and a hole for reception of a spark plug, said apparatus comprising a source of compressed, non-combustible gas, valving means including a manifold and at least one gas distribution valve, said gaS distribution valve being connected to said cylinder at said hole and to said manifold, said manifold also being connected to said source of compressed gas, and valve actuation means connected to said gas distribution valve, said gas distribution valve upon actuation by said valve actuation means permitting introduction of said compressed gas through said spark plug hole from said manifold into said cylinder when said intake and exhaust valves are closed and said piston is in a position to provide a power stroke in said engine.
Claim 3
Dependent Claim
49 words
Apparatus according to claim 1 including bracket means attachable to said engine, said valving means including a housing attachable to said bracket means, said gas distribution valve being cam-operable and mounted in said housing for permitting flow of said compressed gas from said manifold to said spark plug hole.
Claim 4
Dependent Claim
33 words
Apparatus according to claim 2 wherein said valve actuation means includes a cam connectable to the distributor drive of said engine, said cam being engagable with said gas distribution valve for actuation thereof.
