1. a kind of engine system, including:

  • Engine;

    Inlet channel is connected to the engine;

    Compression set comprising along the compressor of inlet channel positioning;

    Barometric pressure sensor is used to measure the atmospheric pressure of the upstream of compressor;

    Manifold Air Pressure sensor is used to measure the Manifold Air Pressure in the compressor downstream;

    AndController is configured in response to being based on the Manifold Air Pressure and the atmospheric pressure during specified operating conditionsThe judgement of the compression set deterioration that predetermined pressure difference between power carries out adjusts operating parameter;

    The wherein described specified operating conditions include one of the following or multiple:

    Engine speed is more than engine speed threshold value;

    Engine horsepower is more than horsepower threshold value, and the horsepower threshold value is set to the horsepower for making the compression set accelerate;

    Engine temperatureMore than temperature threshold;

    Engine on time is more than time threshold;

    Or engine off-load operation level is transported more than engine off-loadRow threshold value;

    AndWherein, the engine system does not include compression set velocity sensor, and to the judgement of compression set deteriorationIndependently of the measurement of compressor speed.
