Supply circuit for supplying at least one fluid to a supercharged engine and method for supplying at least one fluid to the engine

摘要

A circuit for feeding at least one fluid to an internal-combustion engine, notably of Diesel type, includes a circuit (20) for supercharging air to the engine intake, including a supercharging pipe (36), a supercharging device (28) with a compression stage (26) and a compressed air cooling radiator (38), as well as a circuit (22) for recirculating the exhaust gas to the engine intake, including an exhaust gas recirculation pipe (40) and an exhaust gas cooler (46). The feed circuit includes a connecting pipe (50) allowing to connect, upstream from cooler (46), air supercharging circuit (20) and exhaust gas recirculation circuit (22).
