WATER COOLED TURBO-SUPERCHARGER

摘要: PURPOSE:To prevent the temperature of bearings in a supercharger from increasing to value at which bearing seizes up and lubricating oil deteriorating, by changing circulating amount cooling water accordance with both tendency variations thereof. CONSTITUTION:In condition an engine 2 is operated, sensor 60 delivers always detection signal indicating part vicinity controller 50. Meanwhile 50, computer 50A for computing rate per unit time ( deg.C/ sec) computes bearings. The detected are compared critical previously set. When they exceed set values, 50 feeds valve opening control 20 as well drive pump 30 so that excess fed directly radiator 7 through supply pipe 40.
