Abstract:
1. An opposed piston internal combustion engine having a basic module comprising: a combustion chamber defined within a cylinder, a pair of opposed pistons slidably fitted in said cylinder and sealing two sides of the combustion chamber, said pair of opposed pistons comprising a first piston and a second piston, a crankshaft having a plurality of crankpins, said first piston is comprising at a first end a piston crown contained in the cylinder, said first piston is comprising at a second end a first wrist pin, said first piston is comprising arms interconnecting said piston crown and said first wrist pin, wherein said arms, at the first end side of the piston, are extending laterally, with respect to the cylinder, outward, then longitudinally in-line with the cylinder to the side opposite the cylinder from the piston crown, and then inward laterally towards the wrist pin to form an opening which surrounds the cylinder and crankshaft, a first connecting rod drivingly coupling said first piston to a first crankpin of said crankshaft, said first connecting rod being pivotally mounted at an end to said first wrist pin, a second connecting rod drivingly coupling said second piston to a second crankpin of said crankshaft, said second connecting rod being pivotally mounted at an end to a second wrist pin, said second wrist pin moving in unison with said second piston, and a high pressure in the combustion chamber is loading with compressive loads said first connecting rod and said second connecting rod.
