Two-stroke oscillating piston IC engine - has pistons rotating about common axis forming working chambers with valves

摘要

Two stroke two chamber oscillators piston engine has two pistons, which are oscillating about a common rotating axis. This engine uses only few components for power transmission. The pistons are efficiently sealed against the chamber walls and have low wear. The oscillating pistons (20, 2a) connected together form two working chambers (13, 13a) in the upper part (11) of the engine. A working chamber has an exhaust valve and fuel injection valve and ignition arrangements. Slots (14) are arranged in region below the BDC for inlet of air or for air and fuel mixture. An oscillating piston (20a) has connecting rod (31) connected to the pin (32) of a crankshaft (33).
