1. An internal combustion engine comprising:

  • a driveshaft having a first end and a second end and disposed along a driveshaft axis;

    a first cam mounted on the driveshaft, the first cam having a circumferential shoulder of a first cam diameter and a first curvilinear shape with a first frequency;

    a second cam mounted on the driveshaft spaced apart from the first cam, the second cam having a circumferential shoulder of a second cam diameter and a second curvilinear shape which second curvilinear shape has the same frequency as the first curvilinear shape;

    a first combustion cylinder defined along a center cylinder axis, the combustion cylinder having a first end and a second end with an intake port formed in the cylinder between the first and second ends and an exhaust port formed in the cylinder between the intake port and the second end, the center cylinder axis being parallel with but spaced apart from the driveshaft axis a first radius, wherein a combustion chamber is defined within the cylinder between the two cylinder ends;

    a second combustion cylinder having a first end and a second end and defined along second center cylinder axis parallel with the first combustion cylinder central axis but radially spaced apart from the driveshaft axis a second radius larger than the first radius; and

    at least one fuel injector disposed adjacent the center of each combustion cylinder and in communication with the respective combustion chamber.
