Revolution engine

Abstract

Engine for producing mechanical energy by internal combustion of a fuel includes a shaft and a crank arm attached to the shaft. The engine further includes a casing, where the interior of the casing forms a hollow cavity dimensioned to allow the crank arm to rotate within the hollow cavity and the crank arm is capable of making a seal with the interior surface of the casing to block fluid passage. The interior of the casing also includes a bypass area that allows fluid passage around the crank arm. A first valve is positioned adjacent to the bypass area and a second valve is positioned adjacent to the bypass area opposite from the first valve. The first valve and the second valve are configured to block fluid passage when closed.

   a first valve positioned adjacent to the bypass area, wherein the first valve is configured to block fluid passage when closed; and   a second valve positioned adjacent to the bypass area opposite from the first valve, wherein the second valve is configured to block fluid passage when closed.   
     
     
         2 . The engine of  claim 1 , further comprising an exhaust valve configured to control fluid passage to an external of the engine. 
     
     
         3 . The engine of  claim 2 , wherein the exhaust valve is positioned to allow fluid passage from the bypass area to the external of the engine. 
     
     
         4 . The engine of  claim 1 , further comprising an intake valve configured to control fluid passage from an external of the engine. 
     
     
         5 . The engine of  claim 4 , wherein the intake valve is positioned to allow fluid passage from the external of the engine to the bypass area. 
     
     
         6 . The engine of  claim 1 , wherein the hollow cavity is shaped as a cylinder. 
     
     
         7 . The engine of  claim 1 , wherein the crank arm rotates concentrically within the hollow cavity. 
     
     
         8 . A system for producing mechanical energy by internal combustion of a fuel, the system comprising:
 a shaft;   a crank arm attached to the shaft;   a casing, wherein:
 an interior of the casing includes a hollow cavity dimensioned to allow the crank arm to rotate within the hollow cavity, 
 the crank arm is capable of making a seal with an interior surface of the casing to block fluid passage, and 
 the interior of the casing includes a bypass area that allows fluid passage around the crank arm; 
   a first valve positioned adjacent to the bypass area, wherein the first valve is configured to block fluid passage when closed; and   a second valve positioned adjacent to the bypass area opposite from the first valve, wherein the second valve is configured to block fluid passage when closed.   
     
     
         9 . The system of  claim 8 , wherein the crank arm is shaped such that the crank arm can push the first valve and the second valve open as the crank arm rotates. 
     
     
         10 . The system of  claim 8 , wherein the first valve and the second valve are configured to form a seal against the crank arm to block fluid passage as the crank arm rotates. 
     
     
         11 . The system of  claim 8 , further comprising a spark plug. 
     
     
         12 . The system of  claim 11 , wherein the spark plug is positioned to produce a spark in the bypass area. 
     
     
         13 . The system of  claim 8 , wherein the first valve is configured to be closed during a compression phase of an operating cycle of the system, and open during a power phase of the operating cycle of the system. 
     
     
         14 . An apparatus for producing mechanical energy by internal combustion of a fuel, the apparatus comprising:
 a shaft;   a crank arm attached to the shaft;   a casing, wherein:
 an interior of the casing includes a hollow cavity dimensioned to allow the crank arm to rotate within the hollow cavity, 
 the crank arm is capable of making a seal with an interior surface of the casing to block fluid passage, and 
 the interior of the casing includes a bypass area that allows fluid passage around the crank arm; 
   a first valve positioned adjacent to the bypass area, wherein the first valve is configured to block fluid passage when closed; and   a second valve positioned adjacent to the bypass area opposite from the first valve, wherein the second valve is configured to block fluid passage when closed.   
     
     
         15 . The apparatus of  claim 14 , further comprising a camshaft that includes a first cam, wherein the first cam is configured to operate an intake valve. 
     
     
         16 . The apparatus of  claim 15 , wherein the first cam rotates one revolution for every four revolutions of the crank arm. 
     
     
         17 . The apparatus of  claim 15 , wherein the camshaft further includes a second cam, and wherein the second cam is configured to operate the first valve in conjunction with the crank arm. 
     
     
         18 . The apparatus of  claim 17 , wherein the second cam operates the first valve by holding the first valve open after the crank arm opens the first valve. 
     
     
         19 . The apparatus of  claim 14 , wherein the first valve is opened by a cam separate from the crank arm.
