Patent number: 9506394Abstract: A method of controlling the temperature of an engine of a vehicle, such as an internal combustion engine and/or the temperature of one or more auxiliary components of the vehicle, such as a cabin heater for the vehicle includes monitoring one or more parameters of the engine including the temperature of the engine. Optionally data relating to the temperature of the engine is feedback to a control unit. The method includes monitoring one or more requirements of the one or more auxiliary components of the vehicle and/or monitoring one or more parameters of the one or more auxiliary components of the vehicle. In dependence upon said monitoring, the method includes selecting a cooling mode for a cooling system disposed about said engine and said one or more auxiliary components.Type: GrantFiled: May 31, 2013Date of Patent: November 29, 2016Assignee: JAGUAR LAND ROVER LIMITEDInventors: William Hutchins, Stuart Briscoe

Patent number: 9506395Abstract: A cooling system for a supercharged internal combustion engine may include a charge air cooling circuit, in which a low-temperature coolant circulates and which may have a low-temperature charge air cooler for cooling charge air and a low-temperature coolant cooler for cooling the low-temperature coolant. The system may include a refrigerant circuit, in which a refrigerant circulates and which has a vaporizer for vaporizing the refrigerant and a condenser for condensing the refrigerant. The system may include a coupling heat exchanger for a fluidically separated, heat-transmitting coupling of the charge air cooling circuit with the refrigerant circuit. The coupling heat exchanger may be arranged in a vaporizer bypass of the refrigerant circuit thereby bypassing the vaporizer and be arranged in a coupling branch of the charge air cooling circuit. The coupling branch may branch off via a branching-off point from a feed of the charge air cooling circuit.Type: GrantFiled: August 6, 2014Date of Patent: November 29, 2016Assignee: Mahle International GmbHInventors: Tobias Isermeyer, Peter Wieske, Rene Dingelstadt

Patent number: 9506398Abstract: A wastegate valve device for a supercharging device may include a valve disc, which is connected to an actuator device via a drive train. The wastegate valve device may include at least one damping element arranged between the valve disc and the actuator device. The drive train may have an inner section, which is arranged inside a fluid path of a driving fluid. The inner section may include a spindle arm, which is connected to a spindle and to the valve disc. The spindle may be connected to an operating arm, which is arranged in an outer section of the drive train. The operating arm may be arranged outside the fluid path, and may be connected to an operating rod, which is connected to the actuator device. The damping element may be arranged in a connection region of the drive train.Type: GrantFiled: March 19, 2013Date of Patent: November 29, 2016Assignee: Mahle International GmbHInventors: Marius Dusik, Werner Schadler, Peter Wieske

Patent number: 9506400Abstract: A hydrogen generator that can be operated in a broad temperature range is disclosed, which comprises a first ammonia conversion part having a hydrogen-generating material which reacts with ammonia in a first temperature range so as to generate hydrogen; a second ammonia conversion part having an ammonia-decomposing catalyst which decomposes ammonia into hydrogen and nitrogen in a second temperature range; an ammonia supply part which supplies ammonia; and an ammonia supply passage which supplies ammonia from said ammonia supply part to the first and second ammonia conversion parts. The first temperature range includes temperatures lower than the second temperature range, and hydrogen is generated from ammonia by selectively using the first and second ammonia conversion parts. An ammonia-burning internal combustion engine and a fuel cell having the hydrogen generator are also disclosed.Type: GrantFiled: May 1, 2014Date of Patent: November 29, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kyoichi Tange, Norihiko Nakamura, Haruyuki Nakanishi, Hidekazu Arikawa
