    摘要： A fan assembly (10) which incorporates variable pitched blades (152), is driven by the engine of a vehicle and is used in cooling the engine. A control system (248) is provided which is responsive to at least one signal representative of an operating parameter of the engine and a second signal indicative of a desired cooling requirement to establish an efficient pitch for the blades of the fan assembly. In one embodiment, the speed of the engine is sensed and used in combination with a cooling requirement signal developed by the engine control module (205) to regulate the pitch of the fan assembly. In a second embodiment, engine charge air temperature and coolant temperature signals are utilized in establishing the desired pitch. Furthermore, fuzzy logic controls (290) can be utilized to anticipate the cooling needs of the engine based on variations in the overall dynamic system as derived from information available through the engine control module.

    摘要： Methods and systems for maintaining near operational mode internal temperatures of a high temperature fuel cell system during a hibernation mode are provided. Embodiments of the claimed invention include powering an electric heater adjacent to the high temperature fuel cell system to heat the high temperature fuel cell system. The use of an electrical heater allows the fuel cell system to maintain approximate operation mode internal temperatures during a hibernation mode and eliminates the problems of excess noise, vibration and exhaust emissions typical of previous fuel cell system heating methods. Gross energy savings of 67% and a fuel consumption reduction rate of 33% have been shown when substituting this method with previous fuel cell system heating methods with no additional manufacturing costs.

    摘要： A fan assembly (10) includes first and second housing sections (70, 72) which, when mated by a first set of fasteners, define a plurality of circumferentially spaced openings (162) that lead to an internal housing chamber (82). The fan assembly (10) also includes a plurality of blade units (140), each of which includes an integral support stem (142) having a journal portion (148) rotatably mounted within a respective one of the openings (162), an enlarged flange portion (144) and a radial post portion (138) rotatably supported by a hub member (106) within the internal chamber (82). Each blade unit (140) preferably has a thrust bearing (156), bushing sleeve (158) and fan blade (152) integrated with the support stem (142), with the fan blade (152) being preferably molded to the support stem (142) following positioning of the thrust bearing (156) and bushing sleeve (158) to form an integral component. The fan assembly (10) further includes an actuator member (112) that is movably supported within the internal housing chamber (82) and which is adapted to engage a pin (166) of the support stem (142) at a position offset from a rotational axis thereof to adjust the pitch of the fan blades (152). The fan assembly (10) is adapted to be attached to a drive device (12) with a portion (42) of the drive device (12) covering a first set of fasteners (78) such that the first and second housing sections (70, 72) can only be disassembled following detachment from the drive device (12). A sensing arrangement (58, 180) is also preferably provided to generate signals indicative of at least one of the pitch and rotating speed of the fan blades (152).
