1. the heat energy of the Exhaust gas purifying device in the gas exhaust piping (3) that is used to be combined in internal-combustion engine keeps equipment (1), described purification plant has inlet (4) and outlet (5), exhaust from internal-combustion engine can flow into by described inlet, and processed exhaust can be flowed out by described outletIt is characterized in that described equipment comprises:

  • the retractible upstream heat energy holding device that is positioned at described purification plant upstream;

    Be positioned at the retractible downstream heat energy holding device in described purification plant downstream;

    And comprise be used to control described upstream heat energy holding device and described downstream heat energy holding device, respectively with respect to the actuator of the position of the described inlet (4) of described purification plant and described outlet (5), described upstream heat energy holding device and described downstream heat energy holding device can be at (i) motor running positions and are (ii) moved between the heat energy preservation position, at described motor running position, described upstream heat energy holding device and described downstream heat energy holding device are at least in part the position of withdrawal, and allow the exhaust gas to and flow out the pollution abatement device;

    Preserve the position at described heat energy, at least one in described upstream heat energy holding device and the described downstream heat energy holding device correspondingly closed the described inlet and the described outlet of described purification plant.
