A SYSTEM FOR TREATING EXHAUST GASES (ATS) AND SUPERCHARGING OF AN INTERNAL COMBUSTION ENGINE IN PARTICULAR OF AN AGRICULTURAL VEHICLE AND AGRICULTURAL VEHICLE COMPRISING THE SYSTEM

摘要

A system for treating exhaust gases and supercharging of an internal combustion engine (EC), in particular of an agricultural vehicle, the internal combustion engine (CE) comprising an intake line (I) and an exhaust line (E), the system comprising a first supercharger stage (TC1) having a first turbine (T1) arranged on said exhaust line immediately downstream of the internal combustion engine (CE) and related first bypass means (BP1) of the first turbine, a second supercharger stage (TC2) having a second turbine (T2) arranged on said exhaust line downstream of said first turbine (T1) and related second bypass means (BP2) of the second turbine, at least a first exhaust gas treatment stage (ATS1) arranged between said first (T1) and said second turbine (T2), processing means (ECU) configured to bypass said second turbine and maintain said first turbine (T1) operating when the internal combustion engine operates in a first operating condition and vice versa when the internal combustion engine operates in a second operating condition; in which the internal combustion engine supplies less power when it is in said first operating condition if compared to when it is in said second operating condition.
