| 20080308050 | CYLINDER HEAD FOR AN INTERNAL COMBUSTION ENGINE - The invention relates to a cylinder head ( | 12-18-2008 |
| 20110056456 | CYLINDER HEAD WITH OIL RETURN - Engine oil may pool in various locations in the cylinder head near the valves and underneath the camshaft. Rather than directly conducting the oil to the oil return passages, the oil is conducted to a surface proximate the exhaust ducts before being conducted to the oil return passage so that the oil is readily warmed up during a cold start by the contact with a surface in the cylinder head proximate exhaust ducts. The provision of such a surface proximate exhaust ducts is facilitated by the integrated exhaust manifold design in which the exhaust ducts are merged prior to exiting the cylinder head. By rapidly heating the oil, the oil's viscosity decreases, thereby reducing friction and improving fuel efficiency. | 03-10-2011 |
| 20110079187 | HEATING ENGINE OIL IN AN INTERNAL COMBUSTION ENGINE - The disclosure relates to an internal combustion engine having a cylinder head and cylinder block serving as an upper crankcase portion for holding a crankshaft in multiple bearings. The engine has an oil pump for feeding engine oil to the cylinder head prior to supplying the multiple bearings in the cylinder block. | 04-07-2011 |
| 20110197832 | COOLANT JACKETS FOR AN INTERNAL COMBUSTION ENGINE AND METHOD OF CONTROL - An internal combustion engine is provided. The internal combustion engine includes a cylinder block having a cooling jacket and a cylinder head having two cooling jackets. In one example, the internal combustion engine may be operated so as to reduce engine friction and emissions during cold engine starts. | 08-18-2011 |
| 20110271916 | Internal Combustion Engine with Liquid Cooling - A system for providing cooling to at least one cylinder of an engine is disclosed. The system comprises at least one coolant jacket in a cylinder head arranged on an inlet side of a cylinder and at least one coolant jacket in the cylinder head arranged on an outlet side of the cylinder. The outlet-side coolant jacket may be part of a water cooling circuit, while the inlet-side coolant jacket may be part of oil circuit. | 11-10-2011 |
| 20110296834 | SEPARATELY COOLED TURBOCHARGER FOR MAINTAINING A NO-FLOW STRATEGY OF AN ENGINE BLOCK COOLANT JACKET - An internal combustion engine is provided herein. The internal combustion engine may include a turbocharger including a turbine positioned in an exhaust passage, the turbine having a turbine housing. The internal combustion engine may further include a cooling system having an engine block coolant jacket fluidly coupled to a pump, a cylinder head coolant jacket fluidly coupled to the pump, and a turbine coolant passage traversing the turbine housing and fluidly coupled to the pump and bypassing the engine block coolant jacket. | 12-08-2011 |
| 20120006286 | COOLING ARRANGEMENT FOR INTERNAL COMBUSTION ENGINES - A cooling arrangement for an internal combustion engine is described, with a coolant balancing tank which is capable of being filled with coolant and the inlet side of which is connected via a first venting line to an internal combustion engine and/or via a second venting line to a cooler for cooling the coolant, and the outlet side of which is connected via a coolant return line to the inlet side of a pumping device for pumping the coolant through the internal combustion engine. The cooling arrangement has, furthermore, a flow control unit for variably limiting the coolant volume flow in the venting line. | 01-12-2012 |
| 20120067306 | INTERNAL COMBUSTION ENGINE WITH LIQUID-COOLED TURBINE - Embodiments for cooling a turbine of an engine are provided. In one example embodiment, an internal combustion engine comprises a turbocharger including a turbine having a coolant jacket integrated in a housing of the turbine, and an oil circuit coupled to the coolant jacket of the turbine. By cooling the turbine with the oil circuit, the turbine may be constructed from less-heat resistant materials. | 03-22-2012 |
