The turbosupercharger of described type is driven by the exhaust stream of explosive motor generally.For this reason, turbosupercharger has setting turbine within an exhaust-gas stream.Turbine drives compressor by common shaft, the inflation of compressor compresses motor.The parameter describing turbosupercharger function is mainly the volume flowrate or mass flow rate that the ratio of compressor inlet pressure and outlet pressure and compressor transmit.
German patent DE 102007030233A1 discloses a kind of method determining to be equipped with the explosive motor MAF of exhaust turbine supercharger, in the method according to compressor delivery pressure and the ratio of inlet pressure and the rotating speed determination MAF of exhaust turbine supercharger turbine.US Patent No. 6990814B2 discloses a kind of for regulating the method for turbocharger compressor, and the method intention prevents compressor from entering cannot guarantee that the too fast bad operating condition of rotating speed maybe can occur in stable supply inflation.For this reason, the entrance and exit pressure of compressor and rotating speed is measured and by performance plot compared with standard state.When deviating with standard state, activate the valve of compressor bypass to be regulated the rotating speed of compressor by the service a part of compressive charge being recirculated into compressor.
Modern diesel engines and some spark ignition engines have exhaust gas re-circulation apparatus, and it can carry out decreasing pollution discharge by a part of engine exhaust being recirculated into gas charging system.Oxygen concentration in temperature herein between main combustion period in cylinder and the inflation of supply is very important.In the motor with exhaust gas recirculatioon and turbosupercharger, need complicated regulating system to be used for regulating this two parts simultaneously.
Disclose a kind of method for determining turbocharger performance in US Patent No. 7296562B2, wherein according to suction port of compressor and outlet pressure, according to compressor rotary speed and the performance determining turbosupercharger according to the opening time of engine valve and the position of exhaust-gas-recirculation valve.Wherein, other can be used to relate to the data of ambient air and inflation.The compressor determined or the performance of turbosupercharger for regulating exhaust gas recycling system to reduce the pollutant load of engine exhaust.It does not provide the adjustment to turbosupercharger self.

The turbine model of this exhaust turbine supercharger makes it possible to as each combination (inlet pressure of such as exhaust driven gas turbine and the ratio of outlet pressure and rotating speed) of independent input variable distributes or arranges turbocharger efficiency value.Depend on the level of detail of model, interpolation (interpolation) can be performed.On the contrary, by this model that reverses, the rated rotational frequency that turbocharger efficiency is maximum can be determined.This model also directly can provide the adjustment of respective value for exhaust driven gas turbine of controlled variable.
By using predetermined properties figure or model, thus can obtain the adjustment improved further turbosupercharger, it is all best for even wider condition range.
In other preferred embodiment of the present invention, except the controlled variable of exhaust driven gas turbine, also determine the controlled variable regulating exhaust gas recirculatioon.This controlled variable can be in particular and is arranged in exhaust gas recirculatioon pipeline and controls the position that explosive motor is recirculated into the exhaust-gas-recirculation valve of the air displacement in inflation.Corresponding controlled variable can be determined based on the rated rotational frequency of such as exhaust turbine supercharger and actual speed, and activate driving element (particularly exhaust-gas-recirculation valve) with may correspond to.
By changing the setting of exhaust driven gas turbine, such as rotate guide blades by pivot or open or close bypass valve, stress reaction affects inflation pressure and exhaust gas recirculation flow, i.e. the amount of exhaust gas recirculation and/or the proportions of ingredients between fresh air and exhaust gas recirculation in inflation.Due to the turbine efficiency of the different turbosupercharger of each operating condition to motor, multiple inflation pressure and exhaust gas recirculation stream may be set, therefore, it is possible to further optimize by obtaining other adjustment of exhaust gas recirculation stream.
