Marine engine corrosion prevention system

Abstract

An apparatus for prevention of corrosion with the cooling system of an internal combustion engine is disclosed. The apparatus includes a pressurized inert gas source and a fluid delivery system whereby the gas is dispersed within the cooling system to expel corrosion inducing fluids such as oxygen and water vapor.

       2 . The apparatus of  claim 1  wherein the source of inert gas comprises a pressurized tank.  
   
   
       3 . The apparatus of  claim 1  wherein the inert gas is selected from the group consisting of helium and nitrogen.  
   
   
       4 . The apparatus of  claim 1  wherein the first and second couplings are quick disconnect couplings.  
   
   
       5 . The apparatus of  claim 1  further including a valve, said valve being attached to the inert gas outlet.  
   
   
       6 . The apparatus of  claim 5  wherein the valve comprises a solenoid valve.  
   
   
       7 . The apparatus of  claim 5  further including a programmable controller, said controller being connected to said valve.  
   
   
       8 . The apparatus of  claim 5  wherein the valve comprises a pressure regulator.  
   
   
       9 . An apparatus for purging corrosion inducing fluids from a cooling system of an internal combustion engine during storage comprising: 
 a source of inert gas having an outlet;    a first coupling attached to said outlet;    a second coupling in fluid communication with the cooling system whereby the first coupling is adapted to be removably coupled to the second coupling; and    a source of anticorrosive fluid, said source of anticorrosive fluid being in fluid communication with said source of inert gas.    
   
   
       10 . The apparatus of  claim 9  further including a mixing device, said mixing device located at the fluid communication of the anticorrosive fluid and the inert gas.  
   
   
       11 . The apparatus of  claim 9  wherein the source of inert gas comprises a pressurized tank.  
   
   
       12 . The apparatus of  claim 9  wherein the inert gas is selected from the group consisting of helium and nitrogen.  
   
   
       13 . The apparatus of  claim 9  wherein the first and second couplings are quick disconnect couplings.  
   
   
       14 . The apparatus of  claim 9  further including a valve, said valve being attached to the inert gas outlet.  
   
   
       15 . The apparatus of  claim 14  wherein the valve comprises a pressure regulator.  
   
   
       16 . An apparatus for purging corrosion inducing fluids from a cooling system of an internal combustion engine during storage comprising: 
 a source of gas selected from the group consisting of helium and nitrogen, said source having an outlet, said source being coupled to said cooling system;    a first coupling attached to said outlet;    a second coupling in fluid communication with the cooling system whereby the first coupling is adapted to be removably coupled to the second coupling; and    said source being coupled to said cooling system.    
   
   
       17 . The apparatus of  claim 16  wherein the source of gas comprises a pressurized tank.  
   
   
       18 . The apparatus of  claim 16  further including a valve attached to the outlet.  
   
   
       19 . The apparatus of  claim 18  wherein said valve comprises a pressure regulator.  
   
   
       20 . The apparatus of  claim 16  wherein the first and second couplings are quick disconnect couplings.
