Safety device for a supercharged diesel type internal combustion engine (Machine-translation by Google Translate, not legally binding)

Safety device (1) which is fitted in the connection between the charge air pipe (7) and the supercharging-pressure dependent full-load stop (3) of a supercharged diesel type internal combustion engine. The safety device (1) consists essentially of a 3/2-way valve (11) actuated by a control unit (15), and also of a pressure reducing valve (2) arranged in parallel with this 3/2-way valve. The function of the safety device (1) is to simulate a reduced supercharging pressure when critical temperatures of the internal combustion engine are inadmissibly high, e.g. in the case of the engine coolant, and thereby reduce the quantity of fuel supplied.

EL DISPOSITIVO (1) DE SEGURIDAD CONSTA ESENCIALMENTE DE UNA VALVULA (11) DE 3/2 VIAS. EL DISPOSITIVO (1) DE SEGURIDAD TIENE LA TAREA DE SIMULAR PARA EL MOTOR DE COMBUSTION UNA PRESION REDUCIDA DE SOBREALIMENTACION Y CON ELLO DISMINUIR EL VOLUMEN DE INYECCION ALIMENTADO CUANDO LAS TEMPERATURAS LIMITES DEL MOTOR DE COMBUSTION, POR EJEMPLO DEL REFRIGERANTE, SON DEMASIADO ALTAS.
