Methods and systems are provided for controlling an EGR valve and VGT vanes during engine braking. In one example, a method may include during an engine braking event in an engine, coordinating adjustments of both of a cross-sectional area of an inlet of a turbine and an opening of a valve of an exhaust gas recirculation (EGR) system to achieve a desired braking power and to maintain an exhaust system temperature above a threshold temperature during the engine braking event.

Method and systems for engine braking via coordinated EGR and VGT actuation

Methods and systems are provided for flowing a first coolant and a second coolant to a charge air cooler. In one example, a method may include flowing only a first coolant, flowing only a second coolant, or flowing a mixture of the first and the second coolants to the charge air cooler based on engine operating conditions. Further, the method may include adjusting additional engine operating parameters based on a ratio of the first coolant to second coolant flowing to the charge air cooler.

System and method for flowing a mixture of coolants to a charge air cooler

A method for operating an engine system is provided. The method includes during a first condition, flowing exhaust gas from a first exhaust gas conduit to a first turbine inlet of a turbine and flowing exhaust gas from a second exhaust gas conduit to a turbine bypass conduit and during a second condition, flowing exhaust gas from the first exhaust gas conduit to the first turbine inlet and exhaust gas from the second exhaust gas conduit to a second turbine inlet.
