1. An internal combustion engine comprising:

  • a housing;

    a crankshaft, which is rotatably disposed within the housing, and which includes at least one groove formed around an outer surface; and

    a plurality of combustion chambers formed within the housing and disposed around the crankshaft in a substantially parallel relationship to the crankshaft, each combustion chamber including;

    at least one intake port for receiving a fuel and air mixture into the combustion chamber;

    at least one exhaust port for expelling exhaust gases from the combustion chamber;

    at least one piston which slidably moves within the combustion chamber, effective to selectively compress the fuel and air mixture, and which includes a crankshaft engaging portion which engages the at least one groove, effective to rotatably drive the crankshaft; and

    at least one ignition device, which extends into the combustion chamber and which selectively generates energy which ignites the compressed air and fuel mixture, effective to forcibly move the piston within the combustion chamber, thereby rotatably driving the crankshaft.
