Gas discharge valve seat and its arrangement in a combustion chamber of an internal combustion engine and to a method for operating such a gas discharge valve seat

摘要

Receiving gas discharge valve (10), which in a combustion chamber wall (16) of a combustion chamber of an internal combustion engine is arranged, with a dispensing probe (24) and with a device for receiving a volume of gas from the combustion chamber (14), wherein an opening of the dispensing probe (24) at least during the removal of the paste into a region close to the wall of the combustion chamber (14) extends, in which a regular combustion takes place, wherein within the dispensing probe (24) a piston (26) is guided, and wherein the valve (10) has a minimum dead volume, characterized in that the dispensing probe (24) an additional locking device for preventing a collision of the dispensing probe (24) with a is in the direction of its upper dead center is associated with the internal combustion engine piston moving.
