Internal-combustion engine supercharged by exhaust turbo

Abstract

Abstract PURPOSE:To improve the performance at the time of a low speed revolution, by a method wherein a plurality of outlet ducts of bloweres of exhaust turbo chargers are made to join to each other and an air charging bypass valve discharging air into the atmosphere provided in an air charging duct connected with an air charging pipe of an engine is provided. CONSTITUTION:An exhaust sluice valve and a suction sluice valve are closed when an engine speed is less than a half (low speed) of its maximum speed. Although an actuating exhaust turbo supercharger is one unit 32 only and capacity of an exhaust turbine is halved, high charging pressure can be obtained. When the air suction pressure becomes more than a given value at the time of low speed revolution, an air suction bypass valve is opened, suction air is discharged into a bypass duct and the air suction pressure is kept at a given value.
