GAP-SEALED PISTON RING, GAP-SEALED RING-REDUCTION PISTON ENGINE AND RING-REDUCTION RECIPROCATING MECHANISM

摘要

The cut sealing double-ring piston engine has raised oil ring sealing performance, reduced piston ring number from three to two, raised cylinder pressure, reduced friction, less wear, raised endurance, compact structure, reduced weight and volume, saving in machining power consumption and lower cost.
