Air pressure regulator arrangement for an internal combustion

摘要

An air pressure regulating arrangement for regulating charging air pressure of an internal combustion engine which is provided with an exhaust gas turbo-charger including a charging blower and an exhaust turbine. A pressure regulating device responding to charging pressure of a charging blower operates a control device arranged in an exhaust channel by passing the exhaust turbine with the charging air pressure between the charging blower and a load regulating member of the internal combustion engine being monitored so that, upon exceeding a predetermined charging air pressure, the fuel supply to the internal combustion engine is interrupted until such time as the charging air pressure is decreased to the predetermined air pressure whereupon the fuel supply to the engine is then restored.
