| 发明名称 | Method for controlling the speed of an internal combustion engine supercharged by means of a turbocharger | ||
| 摘要 | A method controls an internal-combustion engine (1) supercharged by a turbocharger (12) and including a turbine (13) and compressor (14). The control method includes steps of determining a pressure objective downstream of the compressor (14), determining a critical threshold of a reduced-mass-flow rate that delimits on a “reduced-mass-flow rate/compression ratio” plane a critical area substantially close to achievement of sonic conditions, and filtering by a first filter the pressure objective downstream of the compressor (14) when a current reduced-mass-flow rate is higher than the critical threshold. | ||

| 主权项 | 1. A method for controlling an internal-combustion engine (1) supercharged by a turbocharger (12) and including a turbine (13) and compressor (14), said control method comprising steps of: determining a pressure objective downstream of the compressor (14); determining a critical threshold (Mcritica) of a reduced-mass-flow rate (QAHR) that delimits on a “reduced-mass-flow rate/compression ratio” plane a critical area substantially close to achievement of sonic conditions; and filtering by a first filter the pressure objective downstream of the compressor (14) when a current reduced-mass-flow rate (QAHR) is higher than the critical threshold. | ||
