More Information
Summary:A cooling system for a radiator in an internal combustion engine is provided with a pair of fans connected to a first motor for a small electric current and a second motor for a large electric current, respectively. Relays are provided for operating the first and/or second motor sequentially in accordance with the degree of cooling requirement of the engine. A delay device is provided for delaying the operation of the relay(s) for attaining a stronger cooling requirement for a predetermined short period just after the engine is started. A generation of rush current in the relay contacts is prevented.
