Abstract

The disclosure relates to an internal combustion engine with a cooling circuit having a water jacket portion in the cylinder block and a water jacket portion in the cylinder head which has an intake portion and an exhaust portion. Flow from the intake and exhaust portions mix in an outlet housing which has a cylinder head outlet thermostat. A coolant pump provides flow to a first branch to the exhaust portion and a second branch to the water jacket portion in the cylinder block. A block thermostat is located in the second branch downstream of the coolant pump and upstream of the water jacket portion in the cylinder block. The intake portion of the water jacket portion in the cylinder head is fluidly coupled to the water jacket portion in the cylinder block.
