PURPOSE:To obtain an engine emergency stopping device which is operated certainly at the time of over heating with a simple structure by shutting commu nication between an upper tank and a receiving pressure chamber of a single acting type hydraulic cylinder by means of a soluble bulkhead or a pressure breaking wall which are arranged on the leading out part of a steam leading out pipe in the upper tank. CONSTITUTION:When an engine E is in a over heating condition, the inside of the upper tank 3 of a radiator 2 is filled up with steam of high temperature and high pressure. When the temperature environment inside the upper tank 3 attains the fusing point temperature of a soluble material 19, the soluble material 19 melts so as to communicate the inside of the upper tank 3 with the receiving pressure chamber 15 of a hydraulic cylinder 9 serving as an engine stopping operating tool through a steam loading out pipe 7. The hydraulic cylinder 9 is operated by steam pressure inside the radiator 2, and fuel supplied from a fuel injection pump 1 is shut so as to stop the engine E. By such a way, the auto stopping device of the engine E which is operated certainly at the time of over-heating in a simple structure without necessitating electric power supply can be presented.
