A piston-powered internal explosion engine for providing power output through a rotating crankshaft. The engine includes an engine block having power cylinders for receiving working pistons, bearing means for supporting the crankshaft, and a crankshaft supported within the bearing means having an output end extending outside of the engine block and a plurality of offset power cranks. The engine includes connecting rods operably coupled to the power cranks and configured to transfer power from the working pistons to rotate the crankshaft, and working pistons that are received into the power cylinders and operably coupled to the power cranks. Each working piston has a head end positioned adjacent to a cylinder head to form a compression chamber and is configured to receive power from an explosion of a compressed volume located within the compression chamber, and to transfer the received power to the connecting rods.

1. A piston-powered internal explosion engine for providing power output through a rotating crankshaft having at least one power crank with a lobe, wherein said lobe comprises an arch surface and a concentric surface, said internal explosion engine comprising: an engine block having a power cylinder formed therein for receiving a working piston, wherein said piston is adapted to linearly displace in correspondence with a rotation of said power crank;a connecting rod operably coupled to said power crank and configured to transfer power from said working piston to rotate said crankshaft, said working piston being supported within said power cylinder and operably coupled to said power crank, wherein an arch surface of a hub of said connecting rod interacts with said arch surface of said crank lobe during rotation of said crank, and wherein during said interaction, said linear displacement of said piston is held momentarily static to provide a dwell while said crank continues to rotate through a range of angular positions; anda compression chamber defined at least in part by a head end of said working piston adjacent a cylinder head, said working piston being configured to receive power from an explosion of a detonated compressed volume of air/fuel mixture located substantially within said compression chamber and to transfer the received power to said connecting rod, wherein said compressed volume of air/fuel mixture is held substantially constant, and a desired compression ratio maintained, from an angular position of said rotating crankshaft of at least 20 degrees prior to a top dead center position of said working piston during a compression stroke, to an angular position of at least 20 degrees after said top dead center position of said working piston during a power stroke, and prior to detonation, to facilitate an explosive, rapid expansion reaction at the time of said explosion. 2. The explosion engine of claim 1, wherein a volume ratio of said compression chamber varies in accordance with, at least in part, said angular position of said rotating crankshaft and a corresponding linear position of said working piston, said variable volume ratio being held substantially constant through a range of angular positions of said rotating crankshaft that include said top dead center position of said working piston, said variable volume ratio being graphically represented by a truncated sinusoidal pattern. 3. The explosion engine of claim 1, further comprising: a floating piston cylinder in fluid communication with said power cylinder;a floating piston adapted to travel within said floating piston cylinder in response to various pressures within said compression chamber; anda biasing element adapted to bias said floating piston toward a sealing position, wherein said floating piston seals said compression chamber and said floating piston cylinder, said floating piston separating said floating piston cylinder from said power cylinder, wherein, during said compression stroke of said working piston, said floating piston is caused to displace in response to a threshold pressure within said compression chamber reached at said desired compression ratio, which said threshold pressure overcomes said biasing element causing at least a portion of said air/fuel mixture to shift into said floating piston cylinder, and wherein, during said power stroke of said working piston, said biasing element urges said floating piston toward said sealing position, thus causing at least a portion of said air/fuel mixture to shift back into said power cylinder prior to said detonation. 4. The explosion engine of claim 1, further comprising: a cam surface formed on a journal of said power crank; anda follower surface formed on said connecting rod, wherein a moving interactive relationship between said cam surface and said follower surface retains said working piston at an uppermost position of linear travel between said angular positions of said crankshaft, in which a dead space volume is established between said cylinder head and said working piston. 5. The explosion engine of claim 4, wherein said power cylinder comprises a head having a hemispherical upper surface at least partially defining said dead space volume. 6. The explosion engine of claim 4, wherein said cam surface is truncated along a pitch line of said power crank and said follower surface defines a pitch line of said connecting rod pivoting about said working piston at a topmost position of linear travel.
