20110000188 | HEAT EXCHANGING SYSTEMS FOR MOTOR VEHICLES - A heat exchanging system suitable for use in an exhaust gas recirculation (EGR) circuit comprises a split EGR heat exchanger arrangement. Exhaust gas is used to warm engine oil via a first heat exchanger during initial stages of an engine operating cycle. In the later stages of the operating cycle, recirculated exhaust gases are diverted to flow through the second heat exchanger where they are cooled by the engine coolant. | 01-06-2011 |

20130232951 | THERMOELECTRIC DEVICE FOR OIL TEMPERATURE CONTROL - The present disclosure describes systems and methods to increase the speed of engine warm up by heating oil with a thermoelectric device and also to generate electricity using the same thermoelectric device, exploiting a temperature gradient between engine oil and exhaust gases. The disclosure describes a vehicle engine, comprising: an engine oil reservoir; an exhaust gas system; and a thermoelectric device having a hot side and a cold side and connected to a battery, wherein, the thermoelectric device is configured such that the hot side is thermally coupled to the exhaust gas system and the cold side is thermally coupled to the engine oil reservoir. A diverter valve and duct are provided in the exhaust gas system to selectively convey exhaust gases to the thermoelectric device located in or adjacent to the engine oil reservoir. | 09-12-2013 |
20130306021 | ENGINE SYSTEM AND A METHOD OF MANUFACTURING SAME - An engine system is disclosed in which the transfer of heat from oil flowing through an integrally formed oil transfer passage of the engine is reduced by providing a thermal barrier between the oil and the engine. In one example the thermal barrier is provided by the use of a thick walled plastic tube and in other embodiments ribs are used to separate an oil flow passage from the engine. | 11-21-2013 |

20140305399 | ENGINE BEARING BLOCK ASSEMBLY - A bearing block assembly in an engine is provided. The bearing block assembly includes at least one bearing block to rotatably support an oil lubricated shaft and fastening apparatus to attach the at least one bearing block to a flat mounting surface on a large engine component and a thermal barrier positioned between the shaft and the flat mounting surface configured to reduce the loss of heat to the large engine component from oil used to lubricate the shaft. | 10-16-2014 |
20140352652 | ENGINE OIL SUPPLY SYSTEM AND A METHOD OF CONTROLLING AN ENGINE OIL SUPPLY SYSTEM - An engine oil supply system for a motor vehicle and a method of controlling an engine oil supply system of a motor vehicle is disclosed in which, particularly during an engine overrun period or an engine shut-down, kinetic energy from the slowing engine is used to drive an oil pump so as to store oil in an oil accumulator for later use by one or more engine components without the engine using fuel. The stored oil allows a downsized oil pump to be used thereby saving fuel by providing a supply of oil in addition to or as an alternative to the oil supplied from the oil pump. | 12-04-2014 |
20150252697 | CRANKCASE OIL CATCHER - A crankcase oil catcher configured for placement above a crankshaft and below a piston is described. In one particular example, the crankcase oil catcher has a contour that catches dispersed oil within the crankcase while directing the oil away from a casing wall and towards a crank sump along the contoured surface of the crankcase oil catcher. Inclusion of an aperture within the surface allows for passage of a connecting rod of the crankshaft while providing for a protruding lip around the perimeter of the aperture that prevents oil on the top surface from falling through the aperture. | 09-10-2015 |
