DIESEL ENGINE, DIESEL ENGINE DETAIL, ENSURING THE PRESENTLY INSTALLED STRENGTH, AND METHOD FOR PREVENTING DIESEL ENGINE DAMAGE

摘要

1. The programmed destruction part (7; 107; 407), designed to close the combustion chamber (1) of the emergency engine of the emergency blowdown channel (6) leading through the outer wall (3; 103), where the combustion chamber is surrounded on several sides by a cylinder and, as at least one upper side of at least one piston moving in the cylinder in the up-down direction, which form the outer wall (3; 103) of the combustion chamber (1), and the emergency purge channel (6) is provided in the outer wall (3; 103 ) characterized in that the part is programmed destruction system (7; 107; 407) is designed to protect two-stroke crosshead high power diesel engines with direct-flow purging from all kinds of damage that may arise due to undesirably high overpressure of gases (RU) in the combustion chamber (1) caused by improper operation of the diesel engine, while the programmed destruction part (7; 107; 407) has what is provided in the outer wall (3; 103) the place of the programmed destruction (12), which breaks when the pressure necessary to destroy the place of the programmed destruction (ps) is reached, this is the pressure below the overpressure (ru), starting from which damage occurs in the engine and above the maximum permissible normal pressure in the combustion chamber (pn) under normal engine operating conditions, especially at the pressure necessary to destroy the programmed destruction site (ps) at any temperature (T) in one of the combustion chamber (1) apazone temperature (T0-T1) that is above a threshold pressure (pu) and below a destructive pressure (po) at
