Abstract: A method of controlling exhaust gas delivery between two turbochargers is disclosed. Exhaust gas is delivered to a first turbocharger through a first exhaust conduit. A valve is opened to allow at least some of the exhaust gas from the first exhaust conduit to bypass the first turbocharger through a second exhaust conduit delivering bypassing exhaust gas to a second turbocharger when the first turbocharger reaches a predefined operating speed or when the manifold pressure upstream of the first turbocharger reaches a predefined pressure.

Abstract: A control system for an engine comprising a turbocharger includes a cold light off catalyst (CLOC), a main catalyst, a CLOC valve, and a controller. The CLOC is positioned in a bypass passage around a turbine of the turbocharger. The main catalyst is disposed downstream of the turbine and the CLOC. The CLOC valve selectively routes exhaust flow from the engine between the turbine and the CLOC. The controller determines whether a temperature of the main catalyst is less than a threshold; commands a CLOC mode wherein the CLOC valve routes at least some exhaust to the CLOC based on the temperature being less than the threshold; determines whether a boost is requested at the engine; determines whether a full turbine input is needed to satisfy the requested boost; and disables the CLOC mode based on a determination that a full turbine input is needed.

Abstract: A control device of an exhaust gas-conducting section of a turbocharger includes a pivotable closing device with a closing element and an element lever. A first element portion thereof opens and closes a first flow cross-section of a flow connection and a second element portion opens and closes a second flow cross-section of a bypass duct of the exhaust gas-conducting section. The element lever includes a lever end portion engaging into a cavity of the closing element. A holding element is fixedly connected to the closing element. The lever end portion includes a first contact surface and, axially spaced apart, a second contact surface. The first contact surface includes an axially-extending first partial surface and a radially-extending second partial surface connected to one another by a third partial surface. The partial surfaces are designed to be able to effect contact with the closing element.

Abstract: A system and methods for a turbo-boost control system are disclosed for providing a driver of a vehicle with greater control over vehicle performance. The turbo-boost control system instructs an electronic control unit of the vehicle to increase the manifold pressure to a higher level before releasing the pressure through a waste gate so as to provide a greater power output of the engine. The turbo-boost control system includes a control module, a wiring harness, and a signal adjuster. The wiring harness couples the control module with a turbo inlet pressure sensor, a manifold absolute pressure sensor, and an electronic control unit of the vehicle. The control module sends signals to the electronic control unit based on input readings from the turbo inlet pressure sensor and the manifold absolute pressure sensor. The signal adjuster includes a rheostat that enables manual adjustment of the power output of the engine.

Abstract: A control system for an engine comprising a turbocharger includes a throttle valve, a cold light off catalyst (CLOC), a CLOC valve, and a controller. The CLOC is positioned in a bypass passage around a turbine of the turbocharger. The CLOC valve selectively routes exhaust flow from the engine between the turbine and the CLOC. The controller is configured to command the CLOC valve to a first position whereby exhaust flow is routed to the CLOC in a CLOC mode; determine, based on operation in the CLOC mode, a pressure drop within the turbocharger; and command the actuator to move resulting in increased airflow into the engine while in the CLOC mode.

Abstract: A method for controlling a two-stroke engine operatively connected to a turbocharger, the turbocharger being in fluid communication with the engine to provide a boost pressure thereto. The method includes determining an exhaust temperature representative of an actual temperature of exhaust gas being discharged by the engine; determining a temperature difference between the exhaust temperature and a threshold temperature; in response to the exhaust temperature being less than the corresponding threshold value: determining a corrective amount of boost pressure to add to the boost pressure of the turbocharger, the corrective amount of boost pressure being determined based on the temperature difference; and controlling the turbocharger to increase the boost pressure of the turbocharger by the corrective amount.
