20100326380 | INTERNAL COMBUSTION ENGINE WITH DIRECT COOLING OF CYLINDER COMPONENTS - A mulitcylinder internal combustion engine includes a cylinder block, a cylinder head and a gasket mounted between the cylinder block and cylinder head. A coolant passage extends through the cylinder block and laterally along an uppermost portion of a shared cylinder wall extending between adjacent engine cylinders. The laterally extending cooling passage is defined at least in part by a passage formed in the cylinder head gasket. | 12-30-2010 |
20120312257 | INTEGRATED EXHAUST CYLINDER HEAD - A cylinder head including an integrated exhaust manifold (IEM cylinder head) is coupled to a cylinder block of an engine. The IEM cylinder head comprises an exhaust collector coupled to cylinder exhaust valves, an exhaust port coupled to the exhaust collector, and a coolant jacket for cooling the cylinder head. An upper wall of the cylinder head at a region above the exhaust collector and proximal to the exhaust port may include a degas valve and a temperature sensor. The degas valve may be coupled a top most portion of an upper coolant core of the coolant jacket to direct accumulated steam and/or gas out of the upper coolant core to a degas bottle. The temperature sensor may send a temperature signal to a controller, and if the temperature signal is greater than a threshold, the controller may send an indication to an operator of over-temperature conditions of the engine. | 12-13-2012 |
20130068189 | CYLINDER HEAD ASSEMBLY HAVING AN OIL ROUTING PLUG - An engine provided herein. The engine includes a cylinder head assembly, a cap including an opening, an oil routing plug positioned in the opening including a recess traversing the plug, the recess and a portion of the wall of the opening defining a boundary of a plug oil passage, and an oil supply passage extending through the cylinder head assembly including an inlet fluidly coupled to a lubrication circuit and an outlet opening into the recess. | 03-21-2013 |
20130098315 | ENGINE SEALING ASSEMBLY - A system for an engine is provided. In one embodiment, the system includes a cylinder head, an engine block, and a gasket assembly sealing the cylinder head to the engine block. Further, the gasket assembly may include a plurality of apertures positioned between an inner beading region and an outer beading region to concentrate a clamping load. | 04-25-2013 |
20130239915 | Engine Assembly - An engine cylinder head is provided. The engine cylinder head includes a portion of a first combustion chamber, an upper coolant core and a lower coolant core directing heat from the first combustion chamber and including a first coolant passage and a second coolant passage, the first coolant passage and the second coolant passage laying along a lateral axis, at least a portion of the first coolant passage separated from the second coolant passage via first and second walls. | 09-19-2013 |
20130284128 | HEAD GASKET HAVING VARIABLE AREA COOLANT OPENINGS - An engine assembly is provided herein. The engine assembly includes a head gasket interposing a cylinder block and a cylinder head, the head gasket comprising a first layer in face sharing contact with a portion of a cylinder head attachment surface included in the cylinder block and having a first-layer coolant opening adjacent to two neighboring cylinders and a second layer having a second-layer coolant opening having a smaller cross-sectional area than the first-layer coolant opening. | 10-31-2013 |
20150053155 | HEAD GASKET HAVING VARIABLE AREA COOLANT OPENINGS - An engine assembly is provided herein. The engine assembly includes a head gasket interposing a cylinder block and a cylinder head, the head gasket comprising a first layer in face sharing contact with a portion of a cylinder head attachment surface included in the cylinder block and having a first-layer coolant opening adjacent to two neighboring cylinders and a second layer having a second-layer coolant opening having a smaller cross-sectional area than the first-layer coolant opening. | 02-26-2015 |
20150090203 | ENGINE ASSEMBLY - An engine cylinder head is provided. The engine cylinder head includes a portion of a first combustion chamber, an upper coolant core and a lower coolant core directing heat from the first combustion chamber and including a first coolant passage and a second coolant passage, the first coolant passage and the second coolant passage laying along a lateral axis, at least a portion of the first coolant passage separated from the second coolant passage via first and second walls. | 04-02-2015 |
