FIELD: engines and pumps.
SUBSTANCE: invention relates to internal combustion engines. Two-stroke ICE features opposed pistons fitted in cylinders and pin-jointed with a pair of crankshafts arranged on engine sides. jointing pins are subjected to, in fact, expanding forces acting between pistons and crankshafts. Proposed arrangement reduces or eliminates lateral forces between pistons and cylinder bored walls. Cylinder and pistons are cooled independently to reduce cylindrical deformation caused by thermal expansion in engine operation.
EFFECT: higher power output.
