Abstract:
A system includes a temperature estimation module and a pump control module. The temperature estimation module estimates a temperature of coolant flowing through an engine. The temperature estimation module estimates a temperature of a cylinder wall in the engine based on the estimated coolant temperature and a measured coolant temperature. The pump control module controls a coolant pump to adjust an actual rate of coolant flow through the engine based on the estimated cylinder wall temperature.
