20160138420 | SPLIT TURBOCHARGER BEARING ASSEMBLY - A turbocharger bearing assembly of a split turbocharger for an engine is disclosed in which key rotational parts are rotatably supported by a pair of spaced apart bearings located in a bore of a tubular bearing housing forming part of a bearing assembly. The rotational parts of the turbocharger bearing assembly are balanced as a unit before the turbocharger bearing assembly is assembled to a cylinder block of the engine by insertion into a bore formed in the cylinder block. | 05-19-2016 |
20160138501 | TURBOCHARGED ENGINE EMPLOYING CYLINDER DEACTIVATION - A method of operating a gasoline engine having a first subset of cylinders and a second subset of cylinders includes providing a flow of compressed air from a single-sequential compressor to the engine, selectively deactivating the first subset of cylinders, and igniting gasoline mixed with the compressed air in the second subset of cylinders. The single-sequential compressor includes a dual sided impeller having a first blade arrangement in fluid communication with a first air inlet, and an opposing second blade arrangement in fluid communication with a second air inlet. Additionally, deactivating the first subset of cylinders includes sealing the first subset of cylinders such that the flow of compressed air is provided only to the second subset of cylinders. | 05-19-2016 |

20160186634 | EXHAUST AFTER-TREATMENT SYSTEM FOR AN INTERNAL COMBUSTION ENGINE - An exhaust after-treatment system for an internal combustion engine is provided having an exhaust passage in fluid communication with the exhaust manifold of the engine. A turbocharger coupled to the exhaust passage is operatively driven by a first portion of exhaust gases exiting the exhaust manifold. A bypass line is disposed parallel to the turbocharger, and fluidly coupled to the exhaust passage upstream and downstream of the turbocharger. The bypass line receives a second portion of the exhaust gases exiting the exhaust manifold. A fuel injector disposed in the bypass line injects a pre-determined amount of fuel in the bypass line to the second portion of the exhaust gases. An exhaust after-treatment module located downstream of the turbocharger and the bypass line receives the mixture of the first portion and the second portion of the exhaust gas. | 06-30-2016 |
