<P>PROBLEM TO BE SOLVED: To provide an engine cooling water circulation system for test which is capable of testing test pieces including more types of engines. <P>SOLUTION: An engine cooling water circulation system 1 for test includes a test piece 2 including an engine 3, and a circulation device 5 which circulates and supplies cooling water to the engine 3. The engine 3 includes a cooling water passage 31 which comprises an inflow port 32 which leads in the cooling water cooled by a radiator in mounting into a vehicle, an outflow port 33 which leads out the cooling water to the radiator, a lead-out port 41 which supplies the cooling water to a heating facility of the vehicle, and a lead-in port 42 which collects the cooling water from the heating facility. The circulation device 5 includes a heat exchanger 12 which cools the cooling water, a route through which the cooling water cooled by the heat exchanger 12 can be supplied to the lead-out port 41 and the lead-in port 42, a third three-way valve 15 which is provided in a branching point of the route, a route for supplying the cooling water led from the outflow port 33 and the lead-out port 41 to the heat exchanger 12, and a second three-way valve 14 which is provided at a joining point of the route. <P>COPYRIGHT: (C)2012,JPO&INPIT |
