ABSTRACT:
An opposed piston engine includes at least one pair of pistons synchronously reciprocatingly mounted in a hollow cylinder. At least one projection is formed on the face of one piston, while a corresponding recess is formed on the face of the other piston, the recess being dimensioned to at least partly and preferably substantially receive the projection in the recess, upon reciprocation of the pistons. The piston construction is particularly advantageous in opposed cylinder diesel engines, and can eliminate the need for a glow plug to initiate combustion in even a cold engine.
