| 摘要 |
The invention concerns an engine unit (1) comprising a combustion engine (2) which opens into an exhaust line (11) which is supplied by a set of high-pressure exhaust valves during a high-pressure exhaust phase, and a recirculation line (14) which is supplied by a set of low-pressure exhaust valves during a low-pressure exhaust phase and which is configured in such a way as to be able to be isolated from the exhaust line (11). According to the invention, the engine unit (1) comprises a deactivation system which, when activated, is designed to keep at least one high-pressure exhaust valve closed during the high-pressure exhaust phase. |
