冷システム。In the engine cooling waterway that connects the turbocharged engine and the radiator, there is a water pump driven by the engine on the upstream side of the engine when viewed in the direction of cooling water flow, and a water pump on the downstream side that opens depending on the warm-up state of the engine. In an engine cooling water circuit each provided with a control valve and having a bypass for circulating water from the water pump to the engine when the water temperature control valve is closed, a turbocharger is disposed in the bypass and is attached to a housing of the turbocharger. A water jacket is provided with a cooling water inlet and a cooling water outlet that are formed in a vertical relationship with each other, and a flow is formed that circulates through the above-mentioned bypass before the engine warms up, and after the engine warms up. The turbocharged engine is characterized in that two circulation flows are formed that flow from the radiator to the engine and the turbocharger, and further, when the engine is stopped, convection is generated in the bypass due to a temperature difference between the upstream and downstream parts of the turbocharger. water cooling system.
