Internal Combustion Engine

Abstract

In an engine, blow-by is substantially eliminated and friction is significantly reduced using one or more combinations of non-metallic rings. By substantially eliminating blow-by and by reducing friction, certain engine parameters may be changed. In addition, by substantially eliminating blow-by and by reducing friction, pollution may be reduced, fuel economy may be increased and power may be increased.

1 . A piston for use in an internal combustion engine, the piston comprising:
 a piston body having a first ring groove for receiving a first ring assembly, wherein the first ring assembly includes a first non-metallic ring and a second non-metallic ring;   the piston body having a second ring groove for receiving a second ring assembly, wherein the second ring assembly includes a third non-metallic ring and a fourth non-metallic ring.   
     
     
         2 . The piston of  claim 1 , wherein the piston is designed to be received by a cylinder having a cylinder wall and wherein the first non-metallic ring biases the second non-metallic ring towards the cylinder wall when the piston is received in the cylinder. 
     
     
         3 . The piston of  claim 2 , wherein the third non-metallic ring biases the fourth non-metallic ring towards the cylinder wall when the piston is received in the cylinder. 
     
     
         4 . The piston of  claim 1 , wherein the second non-metallic ring includes a split. 
     
     
         5 . The piston of  claim 4 , wherein the fourth non-metallic ring includes a split. 
     
     
         6 . The piston of  claim 1 , wherein the piston includes a piston head that is recessed to form a combustion chamber. 
     
     
         7 . The piston of  claim 6 , wherein the piston head is coated with a catalyst for oxygen. 
     
     
         8 . The piston of  claim 6 , wherein the piston head has a top and the top is oval-shaped. 
     
     
         9 . The piston of  claim 7 , wherein the piston head has a top and the top is oval-shaped. 
     
     
         10 . The piston of  claim 2 , wherein the piston includes a piston head that is recessed to form a combustion chamber. 
     
     
         11 . The piston of  claim 10 , wherein the piston head is coated with a catalyst for oxygen. 
     
     
         12 . The piston of  claim 10 , wherein the piston head has a top and the top is oval-shaped. 
     
     
         13 . The piston of  claim 11 , wherein the piston head has a top and the top is oval-shaped. 
     
     
         14 . The piston of  claim 3 , wherein the piston includes a piston head that is recessed to form a combustion chamber. 
     
     
         15 . The piston of  claim 14 , wherein the piston head is coated with a catalyst for oxygen. 
     
     
         16 . The piston of  claim 14 , wherein the piston head has a top and the top is oval-shaped. 
     
     
         17 . The piston of  claim 15 , wherein the piston head has a top and the top is oval-shaped. 
     
     
         18 . The piston of  claim 4 , wherein the piston includes a piston head that is recessed to form a combustion chamber. 
     
     
         19 . The piston of  claim 18 , wherein the piston head is coated with a catalyst for oxygen. 
     
     
         20 . The piston of  claim 18 , wherein the piston head has a top and the top is oval-shaped. 
     
     
         21 . The piston of  claim 19 , wherein the piston head has a top and the top is oval-shaped. 
     
     
         22 . The piston of  claim 5 , wherein the piston includes a piston head that is recessed to form a combustion chamber. 
     
     
         23 . The piston of  claim 22 , wherein the piston head is coated with a catalyst for oxygen. 
     
     
         24 . The piston of  claim 22 , wherein the piston head has a top and the top is oval-shaped. 
     
     
         25 . The piston of  claim 23 , wherein the piston head has a top and the top is oval-shaped.
