Abstract: Aspects of the disclosure include a system for controlling an exhaust gas communicated from an engine system to a turbine component of a turbocharger system. The system can include an engine having an operational speed; a turbocharger system including a turbine component, the exhaust gas being output from the engine in an exhaust line; a controller in communication with the engine; and a sensor disposed in the exhaust line being in communication with the controller, the system operating according to the following method: measuring the first temperature of the exhaust gas, determining if the measured first temperature of the exhaust gas is within a temperature safety window of the system; calculating an engine speed of the engine; and adjusting an engine speed setpoint and speed of the engine based on the measured first temperature and the calculated engine speed.

Abstract: Aspects of the disclosure include a system for controlling an exhaust gas communicated from an engine system to a turbine component of a turbocharger system. The system can include a sensor configured to determine a temperature of the exhaust gas; and a controller configured to adjust an engine system speed based on the temperature of the exhaust gas being greater than or less than a temperature safety window.

Abstract: A digital subscriber line access multiplexing apparatus is disclosed in the invention, including subscriber side wide band service processing module, multiplex/demultiplex module, memory, network side processing module. Using the invention, the multiplexing apparatus could locate farther, and the distance of the signal transferring would be longer, satisfying the wide band service needs of the out-of-the-way area; and for the places where the optical fibers aren't laid or there is no free optical transmitting resources, there is no need to put large amount of manpower and material resources to lay the optical fiber or increase the optical transmission equipment, while satisfying the needs of wide band services. A method employing the digital subscriber line access multiplexing apparatus for signal transferring is also disclosed in this invention.
