Diluting fuel-in-oil separating apparatus of internal combustion engine

Abstract

The diluting fuel-in-oil separating apparatus includes an oil container (an oil pan) and a fuel eliminator (a heater, a bubble generator). The oil container contains lubricating oil of the internal combustion engine, and has a first compartment and a second compartment divided from the first compartment, such that the lubricating oil is introduced from the first compartment into the second compartment. The fuel eliminator eliminates fuel from the lubricating oil in the first compartment. The second compartment is provided with an oil passage having an oil pump supplying the lubricating oil from the second compartment to lubricated parts of the internal combustion engine.

 the fuel eliminator comprises a heater configured to heat the lubricating oil of the internal combustion engine; the first compartment is configured to contain the lubricating oil heated by the heater; and the second compartment is divided from the first compartment, such that the lubricating oil heated by the heater is introduced from the first compartment into the second compartment,   the diluting fuel-in-oil separating apparatus of the internal combustion further comprising:   an oil guide provided in a main body of the internal combustion engine and configured to guide the lubricating oil into the first compartment after the lubricating oil lubricates a piston among the lubricated parts of the internal combustion engine.   
   
   
       3 . The diluting fuel-in-oil separating apparatus of the internal combustion engine according to  claim 2 , wherein a volume of the oil contained in the first compartment is smaller than that contained in the second compartment. 
   
   
       4 . The diluting fuel-in-oil separating apparatus of the internal combustion engine according to  claim 2 , wherein the heater heats the lubricating oil flowing from the first compartment into the second compartment. 
   
   
       5 . The diluting fuel-in-oil separating apparatus of the internal combustion engine according to  claim 3 , wherein the heater heats the lubricating oil flowing from the first compartment into the second compartment. 
   
   
       6 . The diluting fuel-in-oil separating apparatus of the internal combustion engine according to  claim 2 , wherein a heat source for the heater is exhaust of the internal combustion engine. 
   
   
       7 . The diluting fuel-in-oil separating apparatus of the internal combustion engine according to  claim 3 , wherein a heat source for the heater is exhaust of the internal combustion engine. 
   
   
       8 . The diluting fuel-in-oil separating apparatus of the internal combustion engine according to  claim 1 , wherein the fuel eliminator comprises a bubble generator configured to generate bubbles in the lubricating oil in the first compartment. 
   
   
       9 . The diluting fuel-in-oil separating apparatus of the internal combustion engine according to  claim 8 , wherein a volume of the oil contained in the first compartment is smaller than that contained in the second compartment. 
   
   
       10 . The diluting fuel-in-oil separating apparatus of the internal combustion engine according to  claim 8 , wherein a main body of the internal combustion engine is provided with an oil guide configured to guide the lubricating oil into the first compartment after the lubricating oil lubricates a piston, which is the lubricated part. 
   
   
       11 . The diluting fuel-in-oil separating apparatus of the internal combustion engine according to  claim 9 , wherein a main body of the internal combustion engine is provided with an oil guide configured to guide the lubricating oil into the first compartment after the lubricating oil lubricates a piston, which is the lubricated part.
