20130170948 | TURBOCHARGER BYPASS SYSTEM - A turbocharger bypass system and method for minimizing the occurrence of oil seepage from the bearing housing into the compressor housing as a result of a pressure differential across the bearing housing and the compressor housing. A bypass system with a pressure dependent check valve is connected to the inlet air passage of a turbocharged engine. When the pressure in the inlet air passage drops to below atmosphere or a predetermined level of depression, the check valve opens to allow a flow of atmospheric air into the inlet air passage, thus minimizing or eliminating the pressure differential generated as a result of a vacuum in the inlet air passage during motoring conditions, or when an exhaust valve downstream of the turbocharger is closed, such as during engine braking. The bypass system is applicable to both single stage and dual stage turbocharged internal combustion engines. | 07-04-2013 |

20150107553 | ENGINE BRAKING - A system and method for controlling the quantity of compressed air that may enter into an engine cylinder during the intake stroke of a piston during an engine braking event. A control throttle may be positioned to restrict the quantity of compressed air that may enter into the cylinder during the intake stroke. The control throttle may also be positioned downstream of the engine and configured to adjustably restrict the quantity of exhaust gas that may be delivered to a turbine. By restricting the exhaust gas delivered to the turbine, the power generated by the turbine that is used by the compressor to compress intake air may also be reduced. Moreover, by controlling the power available to the compressor, the quantity of compressed intake air may be controlled, which allows for control of the quantity of compressed air that enters into the cylinder during the compression stroke. | 04-23-2015 |
