Engine construction

An engine comprising:

• a housing;
• a pair of cylinders attached to said housing arranged in an oppositely facing in-line manner;
• a piston movably mounted within each of said cylinders, each said piston connected to a connecting rod, each said connecting rod being rotatably mounted upon a crank pin of a crank shaft, said connecting rods having a rotational axis defined as a first axis, said first axis being displaced from the axis of said crank shaft;
• a planet gear assembly attached to said crank shaft with the rotating axis of said planet gear assembly coinciding with said crank shaft axis, said planet gear assembly including at least one in number of planet gears, said planet gear assembly operatively connected with an internal ring gear assembly, said internal ring gear assembly including at least one in number of internal ring gears, the diameter of said planet gear being one-half the diameter of said internal ring gear;
• and
• a planetary crank carrier assembly located about said crank shaft, said planetary crank carrier assembly including at least one in number of planetary crank carriers, said crank shaft being rotatably mounted within said planetary crank carrier assembly, said planetary crank carrier assembly being rotatably mounted to said housing, said crank shaft being eccentrically located with respect to the rotating axis of said planetary crank carrier assembly, a said planetary crank carrier located between a said crank pin and a said internal ring gear, said planetary crank carrier assembly being operatively connected to an output gear assembly which is connected to an output shaft.
