Abstract
An engine having a multi flow rate control valve may include a valve, a valve housing and a driving unit. The valve may have a hollow pipe structure and coolant holes through which a coolant supplied to a space at a center portion of the valve is to be distributed and cooled outside of the valve. The valve housing may be coupled with the valve such that an inner side of the valve housing is capable of being in close contact with an outer side of the valve, and have coolant outlets formed at positions corresponding to the coolant holes. The driving unit may rotate the valve to selectively connect the respective coolant holes to the corresponding coolant outlets or close the coolant holes by bringing them in close contact with the inner side of the valve housing.
