Abstract:
An engine having a piston-cam assembly powertrain, said piston-cam assembly powertrain further comprising:a rotary part and a reciprocating part, a. said rotary part comprising: (i) a first cam plate and a second cam plate, wherein said first and said second cam plates are drivingly connected to a power output shaft a sufficient distance apart to define an annular groove therebetween; wherein (ii) said first and second cam plates present identical cam surfaces; and b. said reciprocating part comprising: (i) a rocking yoke having a first end and a second end positioned between said first and second cam plates, said rocking yoke being pivoted at a point between said first end and said second end; (ii) a first cam follower connected to said rocking yoke at said first end and a second cam follower connected to said rocking yoke at said second end, said cam followers being in contact with said cam surface of said rotary part; (iii) a first connecting rod connecting said first cam follower to a first piston reciprocating in a first cylinder and a second connecting rod connecting said second cam follower to a second piston reciprocating in a second cylinder, said first cylinder and said second cylinder being parallel to each other; wherein said reciprocating pistons cause oscillation of said cam followers to rotate said power output shaft.
