An internal combustion engine having a cylinder block comprising one cylinder or a plurality of cylinders, a piston reciprocable in each cylinder, a crank shaft, a cylinder head with inlet and exhaust valves, inlet and exhaust conduits, an ignition or injection device and valve timing means operatively associated with the cylinder head, fuel supply means in communication with the engine intake side, a feed line for supplying a pressurized or ambient air pressure additional fluid such as a gaseous or a liquid fluid to the cylinders of the engine toward a location upstream of the inlet valve seat(s). The feed line outlet may be formed as a Venturi tube. The feed lines and portions of the intake and exhaust conduits may be incorporated into an intermediate flange member adapted to be mounted on the engine block intermediate the intake/exhaust conduits and respective associated intake/exhaust manifolds. The feed lines may include non-return valve means. The additional fluid may comprise air, starter gas or an emulsion made up of drilling oil and water.

In an internal combustion engine at least one cylinder, a piston reciprocal within said cylinder, a cylinder head, inlet and exhaust valves located in said cylinder head, a valve seat in said cylinder head for each of said inlet and exhaust valves, one of an ignition and an injection device mounted in said cylinder head, an inlet conduit opening to and extending upstream of said inlet valve, an exhaust conduit opening from and extending downstream of said exhaust valve, a feed line communicating with and located within the inlet conduit upstream of the inlet valve, said feed line having an outlet orifice in said inlet conduit and disposed in the immediate vicinity of said valve seat of said inlet valve at a location which with respect to said valve seat is as remote as possible from the one of said ignition and injection device, control means at the opposite end of said feed line from said outlet connecting said feed line to the atmosphere, and said control means arranged to limit the amount of air drawn in through said feed line to not more than 5% of the swept volume of said cylinder.
