ABSTRACT:
An opposed piston internal combustion engine comprises an output shaft, at least one cylinder, at least one pair of first and second opposed pistons slidable in said cylinder, a first cam connected to the output shaft and a first cam follower assembly connecting the first piston to the first can, a second cam connected to the output shaft and a second cam follower assembly connecting the second piston to the second cam, an intake valve comprising a slide valve obtained by first piston covering and uncovering an intake port provided in a sidewall of the cylinder at a first end of the cylinder, and an exhaust valve comprising a slide valve obtained by the second piston covering and uncovering an exhaust port provided in the sidewall of the cylinder at a second opposite end of the cylinder, the first and second cams cooperating to provide a cycle of relative movements between the pistons and of valve actions giving rise to five cycles of (i) intake, (ii) compression, (iii) expansion, (iv) exhaust, and (v) return, during which the opposed pistons travel towards a same end of the cylinder.
