Device for expanded gas outlet for piston internal combustion engine supports operation of conventional exhaust device, has e.g. automatic pressure valve and exhaust opening in cylinder side wall

摘要

The device supports the operation of a conventional exhaust device and has an automatically operating pressure valve and an exhaust opening in the cylinder side wall. The pressure valve closes the opening from the outside. The opening is exposed by the piston before reaching bottom dead center and the pressurized exhaust gases automatically open the valve and escape. A controlled valve can be used instead of the automatic valve.
