INTERNAL COMBUSTION ENGINE

摘要

An internal combustion engine comprising a piston (4) slidably disposed for rectilinear reciprocal movement within a cylinder (3). A drive rack (5) pivotally mounted to the piston (4) carries a continuous internally facing row of teeth (19). A drive gear (21) nonrotatably keyed to a drive shaft (2) and internally adjacent to the continuous row of teeth (19) engages a portion of the drive rack teeth. A runner (10) guides the drive rack (5) such that the drive gear (21) cooperatively associates with the drive rack teeth (19) to convert rectilinear movement of the reciprocating piston (4) into rotary movement.
