<p>A two-stroke crosshead large Diesel engine, comprising at least one combustion chamber, which is enclosed on multiple sides by a cylinder, and by at least one upper side of at least one piston moving up and down in the cylinder, which form an outer wall for the combustion chamber. The combustion chamber on its outer wall presents a predetermined breaking point, which is suited to protect the Diesel engine against possible damages which might be caused by an undesirably high overpressure (py) of gases in the combustion chamber during a malfunction of the Diesel engine. The predetermined breaking point comprises a predetermined breaking pressure (ps) below the overpressure (py) above which damages are expected, and above a combustion chamber normal pressure (pn) provided at a maximum during normal engine operation conditions.</p> |
