Patent ID: 8857404

Claim:
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; and a 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.
