An opposed piston engine, comprising:
- a cylinder having a cylinder wall;
- and
- a pair of opposed pistons, each piston of the pair of opposed pistons having a face, the pair of pistons being disposed in the cylinder and movable between first positions in the cylinder in which faces of the opposed pistons and the cylinder wall define a maximum volume and second positions in the cylinder in which the faces of the opposed pistons and the cylinder wall define a minimum volume,
- wherein each face of each piston of the pair of opposed pistons has a top plane and a recess formed therein, each recess comprising a first surface defining part of a cone, the cone defined by the first surface of at least one of the recesses having a longitudinal axis that defines an angle equal to at least one half of a cone angle of the cone with the top plane.
