Abstract
Internal combustion engine with exhaust gas recirculation and turbocharger. The branch (9) connecting the exhaust duct (4) and the inlet duct (5) is situated upstream of the exhaust turbine (6) and downstream of the inlet compressor (7). This branch (9) discharges into the inlet duct via a venturi (10). The regulation of the quantity of exhaust gas is controlled by controlling the exhaust-pressure-regulating devices. These may comprise a turbine with variable geometry.
