The thermal increase mode flows the coolant at a second coolant temperature greater than the first coolant temperature thereby increasing the exhaust temperature of the exhaust gas. The thermal decrease mode flows the coolant at a third coolant temperature less than the first coolant temperature thereby decreasing the exhaust temperature of the exhaust gas. |
