Abstract: A control valve of a multi-supercharger system is provided. The control valve includes a first spool rotatably fitted in a valve body and a second spool fitted in the valve body to be coaxially rotatable together with the first spool. A disk member is installed in the valve body to partition a first chamber, in which the first spool is disposed, and a second chamber, in which the second spool is disposed, from each other. A portion of the disk member includes a communication sector, through which the first chamber and the second chamber communicate with each other. A first inlet and a first outlet are disposed in the valve body and a second inlet and a second outlet are disposed in the valve body. A first valve aperture is formed in the first spool for allowing the first spool to communicate with the communication sector.

Abstract: An auxiliary cooling system which is provided separately from an engine cooling passage in a vehicle provided with a turbo engine. The auxiliary cooling system includes a first line which connects a radiator and an intercooler to each other and on which an electric water pump is installed. A second line connects the intercooler and an intake manifold. A third line connects the intake manifold and the radiator, and a bypass valve selectively directly transfers cooling water, heated while passing through a turbine housing provided on a path of the third line, to the radiator or transfers the cooling water to the radiator via an engine block or a heater. Cooling water discharged from the intake manifold passes through an ETC (electronic throttle control) unit and thus reduces a temperature of intake air passing through the ETC unit.
