Abstract

PURPOSE:To give an optimum supercharged pressure in an equipment which controls a maximum supercharged pressure at the lower side of a supercharger to a set value by providing a corrective device which changes the specified value of the maximum supercharged pressure controller on the basis of detected temperatures of an engine. CONSTITUTION:An output of a temperature sensor 12 is sent to a comparative circuit 22a in the form of a voltage signal A proportional to an engine temperature and compared with a set level B stored in a set voltage generating circuit 22b. When the result is A>B, an output voltage C is generated and turned into an electro-magnetic valve actuating voltage D via an actuating circuit 22c to ease a spring 21c of a supercharging relieve valve 21 for advancing a timing at which the relief valve 21 is opened, that is, reducing the set value of a maximum supercharged pressure. In either thermal condition of an engine where it is overheated or cold, an optimum supercharged pressure may be provided.
