    摘要： A very low water (VLW) heat transfer fluid, having an atmospheric boiling point of about 148° C. (about 300° F.) and a low temperature operating limit (LTOL) of −40° C. or below, comprised of one or more polyhydric alcohols, one or more corrosion inhibitors, and between 5% and 10% water. The heat transfer fluid retains many of the features of a non-aqueous heat transfer fluid, while providing a substantially lower viscosity. The heat transfer fluid is suitable for use in internal combustion engines as an engine coolant and in other heat transfer applications.

    摘要： An engine cooling device including a water pump (30), a radiator (20), an exhaust heat recovery unit (40), and a coolant circulation circuit (1) for circulating a coolant in these apparatuses includes a flow rate limiting means that limits the flow rate of the coolant that circulates in the exhaust heat recovery unit (40) in the case where a temperature (Ta) of a sensor element (81) of an A/F sensor (80), that is disposed downstream of the exhaust heat recovery unit (40) in an exhaust path, is below a preset activation temperature (T1). An extent of opening of a second switching valve (70) is made smaller in the case where the temperature (Ta) of the sensor element (81) is below the activation temperature (T1) than in the case where the temperature is equal to or higher than the activation temperature (T1).

    摘要： The present invention relates to a cooling system for cooling of a combustion engine (1). The system comprises a pilot line (12) which has an inlet (12a) to receive coolant from a line (3) of the cooling system and a thermostat (6) comprising a sensing element (6b) adapted to monitoring the temperature of the coolant in the pilot line (12) and a valve (6a). The cooling system comprises a thermal device (13, 26, 31) in contact with the coolant in the pilot line (12) at a location upstream of the sensing element (6b), and a control unit (15) adapted to estimating when it is appropriate to alter the coolant's operating temperature in the cooling system and, at such times, to activating the thermal device (13, 26, 31) so that it warms or cools the coolant in the pilot line (12).
