    摘要： An expansion tank system for a liquid cooling system includes a first chamber for receiving a coolant, a second chamber for pressurized gas, a first gas conveying device for conveying gas from the first to the second chamber, a second gas conveying device for conveying gas from the second to the first chamber, a first pressure sensor in fluid communication with the first chamber, and a control unit connected to the first gas conveying device, the second gas conveying device and the first pressure sensor for controlling the second conveying device to selectively convey gas from the second to the first chamber if a pressure measured through the first pressure sensor is below a predefined first threshold value, and for controlling the first conveying device to convey gas from the first to the second chamber if a pressure measured through the first pressure sensor is above a second threshold value.

    摘要： A drive device comprising at least one control unit (10) for operating a first drive unit (16) with a first operating frequency (fb1) from a first operating frequency interval and a second drive unit (18) with a second operating frequency (fb2) from a second operating frequency interval, which at least partly overlaps the first operating frequency interval. The control unit (10), in at least one operating state, operates the drive units at least occasionally simultaneously with different operating frequencies (fb1, fb2) and varies the first operating frequency (fb1) and/or the second operating frequency (fb2) within the respective operating frequency interval.

    摘要： During engine warm-up, a flow regulating unit in a cooling system operates in a fuel efficiency priority mode. In this mode, a head-side cooling water flow rate (Qhd) is regulated to be equal to or smaller than a first upper limit; a block-side cooling water flow rate (Qbk) is regulated to be equal to or smaller than a second upper limit; and cooling water flowing out of a block-side passage and a head-side passage flows mainly into a bypass passage. When a heating request to heat blown air is made during engine warm-up, the regulating unit operates in a heating priority mode. In this mode, Qhd is regulated to be equal to or smaller than a third upper limit; Qbk is regulated to be equal to or smaller than a fourth upper limit; and at least cooling water flowing out of the head-side passage flows into a heat exchanger.
