Title:
クーラントによって冷却される内燃機関用のクーラント回路
Document Type and Number:
Japanese Patent JP4608539
Kind Code:
B2
Abstract:
In a coolant circuit for an internal combustion engine having two cylinder banks, a radiator for cooling the engine coolant, a pump and a thermostatic valve including a mixing chamber and first and second flow control valves, wherein the pump is connected to the radiator via an intake line for receiving coolant therefrom and supplying it to the cylinder banks which are in communication with the mixing chamber from which a radiator line extends to the radiator for returning heated coolant to the radiator under the control of a flow control valve, or supplying it via a bypass line to the intake line under the control of a bypass valve, a heating circuit is provided extending from one of the cylinder banks via a heater to the pump intake line and a heater control valve is disposed in the heating control circuit so that, upon opening of the heater valve, coolant flows from the other cylinder bank via the mixing chamber to the one cylinder bank and coolant from both cylinder banks jointly flows through the heating circuit back to the pump.
