| 摘要 |
The invention relates to a double-acting two-stroke internal combustion engine with at least one cylinder and a twin piston on a rectilinearly guided piston rod with exhaust ports in the middle area of the cylinder, with inlet devices to both working chambers and with at least one charging device connected to the inlet devices. Known combustion engines of this type are expensive in terms of their inlet control and function with unsatisfactory efficiency and high exhaust emission. According to the invention, a compact internal combustion engine functioning with high efficiency and low exhaust emission is created in that the piston rod is of continuous design with at least one hollow chamber and is guided in both ends of the cylinder and that a first flow connection is provided between the hollow chamber of the piston rod and the charge device and alternately open second flow connections are provided between the hollow chamber and each working chamber. In this way the hollow piston rod takes over the inlet control.
