| 摘要 |
The invention relates to a method for controlling a vehicle engine (10), said method being characterised in that it comprises a step for measuring a pressure P4<SUB>m</SUB> at the output of a turbine (61) of a turbocompressor (60), in such a way that a supercharging pressure P2<SUB>m</SUB> in an intake manifold of the engine is regulated. In one form of embodiment, the regulation is carried out according to a differential pressure at the terminal of the turbine, corresponding to a difference between P4<SUB>m</SUB> and a pressure P3<SUB>m</SUB> at the input of the turbine. In another form of embodiment, the regulation is carried out according to an expansion ratio in the turbine corresponding to a ratio between the pressures P3<SUB>m</SUB> and P4<SUB>m</SUB>. The invention also relates to a system for implementing said method. |
