Abstract:
1. A method for operating a cooling system in an internal combustion engine having a turbocharger including a turbine positioned in an exhaust passage and a cooling system including a pump fluidly coupled to an engine block coolant jacket of an engine block, a cylinder head coolant jacket of a cylinder head, and a turbine coolant passage traversing a housing of the turbine, the method comprising: during a first operating condition, flowing coolant from the pump into the cylinder head coolant jacket and the turbine coolant passage and inhibiting coolant flow from the pump to the cylinder head coolant jacket, the cylinder head coolant jacket fluidly connected to the engine block coolant jacket in a parallel flow configuration, the parallel flow configuration being one in which an inlet of the engine block coolant jacket is fluidly coupled to an inlet of the cylinder head coolant jacket at a first location apart from the engine block and the cylinder head and an outlet of the engine block coolant jacket is fluidly coupled to an outlet of the cylinder head coolant jacket at a second location apart from the engine block and the cylinder head.
