Abstract
The present invention relates to an internal combustion engine (1), having an intake section (2) which has an intake line (3) in which a compressor (4) of an exhaust-gas turbocharger (5) is arranged; having an exhaust section (6) which has an exhaust line (7) in which a turbine (8) of the exhaust-gas turbocharger (5) is arranged; and having a low-pressure exhaust-gas recirculation device (9) which has an exhaust-gas recirculation line (10) which branches off from the exhaust line (7) downstream of the turbine (8) and which opens into the intake line (3) upstream of the compressor (4) and in which an exhaust-gas recirculation valve (11) is arranged. Here, a throttle device (12) is arranged in the intake line (3) upstream of the compressor (4).
Claims12
An internal combustion engine (1),
- having an intake section (2) which has an intake line (3) in which a compressor (4) of an exhaust-gas turbocharger (5) is arranged;
- having an exhaust section (6) which has an exhaust line (7) in which a turbine (8) of the exhaust-gas turbocharger (5) is arranged;
- having a low-pressure exhaust-gas recirculation device (9) which has an exhaust-gas recirculation line (10) which branches off from the exhaust line (7) downstream of the turbine (8) and which opens into the intake line (3) upstream of the compressor (4) and in which an exhaust-gas recirculation valve (11) is arranged, and
- having a throttle device (12) arranged in the intake line (3) upstream of the compressor (4),
- wherein the exhaust-gas recirculation valve (11) and the throttle device (12) are combined to form a module (22).
