Abstract:
1. A cooling system for an engine including a cylinder head and a cylinder block, comprising: a coolant pump; a pre-chamber connected to the coolant pump to temporarily store coolant pumped by the coolant pump; a first coolant line connected to the pre-chamber for guiding coolant to flow through the cylinder head; a second coolant line connected to the pre-chamber for guiding coolant to flow through the cylinder block; a first thermostat connected to the first and second coolant lines to receive the coolant discharged from the cylinder head and the cylinder block, the first thermostat being configured to control a flow of the coolant discharged from the cylinder block in response to a temperature of the coolant; a radiator connected to the first thermostat to receive at least a portion of the coolant discharged from the first thermostat, the radiator being configured to radiate heat of the coolant; and a second thermostat connected to the radiator and the coolant pump, the second thermostat being configured to control a flow of the coolant from the radiator to the coolant pump in response to a temperature of the coolant.
