An aqueous, non-ionic coolant composition is used in a cooling circuit (14) of the internal combustion engine (11). In order to also ensure long-lasting protection against corrosion for light metal components of the engine that come into contact with the coolant, e.g. components made of magnesium or magnesium alloys, the cooling circuit has at least one deionization device (28), for example, an ion exchanger, for the coolant.Type: GrantFiled: May 16, 2003Date of Patent: August 12, 2008Assignee: BASF AktiengesellschaftInventors: Bernd Wenderoth, Stefan Dambach

Patent number: 7337755Abstract: A cylinder head cooling structure and an oil temperature control system are provided for an internal combustion engine having a plurality of cylinders, each having a plurality of intake ports and a plurality of exhaust ports. The engine includes cooling oil jackets surrounding the spark plugs in the cylinder head, a thermostat attached to the front surface of the crankcase independently of an oil filter, and an oil temperature sensor disposed on a rear face of the cylinder block above the crankcase in an oil supply path formed on the cylinder rear face for supplying oil to the oil jackets. Oil passages conducting oil into the oil jacket are provided between two separate parts of a bifucated intake port and between two separate parts of a bifurcated exhaust port, and only cooling system oil reaching high temperatures is allowed to flow through the thermostat, thereby improving temperature control response.Type: GrantFiled: September 26, 2005Date of Patent: March 4, 2008Assignee: Honda Motor Co., Ltd.Inventors: Yoshitsugu Gokan, Katsuji Yamamoto

Patent number: 7125499Abstract: Liquid phase liquid crystal polymers (LCPs) are disclosed having a composition and structure that can be varied to provide desirable properties. The liquid phase LCPs have polyiminoborane, polyaminoborane, and/or borozine polymer backbone molecules, with silicon and/or phosphorous side chain molecules linked to the backbone that provide a degree of alignment assigned an Order Parameter (S), defined as S=? [3 cos2 ??1], where ? is the angle between the axis of an LCP molecule and the vertical direction. The inventive liquid phase LCPs have an average Order Parameter in the range of about 0.2 to about 0.99 and are applicable to a number of rinse, coolant, lubricant, sterilization and other protectant processes.Type: GrantFiled: August 12, 2002Date of Patent: October 24, 2006Assignee: LCP Tech Holdings, LLCInventors: Thomas David Ferguson, Rakesh Govind

Patent number: 6938605Abstract: An oil cooling system to provide enhanced thermal control for internal combustion engines wherein the oil cooling system of the present invention works in conjunction with the standard oil lubrication circuit and typical liquid coolant system of an engine to maintain the engine temperature in a constant range even when operated in an environment with extreme thermal conditions for a prolonged period of time. The present invention detects when the oil temperature has exceeded a pre-determined range and sends the oil to a radiator with heat sinks and a fan for extracting the heat therefrom and dissipating it before recycling it back to the oil sump where it serves to lubricate and cool the heat-generating components it comes in contact with.Type: GrantFiled: January 8, 2004Date of Patent: September 6, 2005Inventor: Osama Othman Mostaeen Al-Khateeb
