Cooling water supply device for internal combustion engine testing equipment

Abstract

Abstract PURPOSE:To prevent the occurrence of rust of an internal combustion engine being in stock by preparing a diluted antifreeze having a certain concentration in a diluting tank and supplying it to the internal combustion engine as cooling water. CONSTITUTION:A diluting tank chamber 11 is provided to connect an antifreeze supply pipe 15 and a service water supply pipe 16, and a cooling water tank chamber 10 is provided and is connected to the tank chamber 11 through a cooling water transporting pipe 26, and a cooling water supply pipe 44 to an internal combustion engine testing equipment 48 is connected to the tank chamber 10. A certain quantity of supplied antifreeze A and service water B are mixed to prepare diluted antifreeze having a desired concentration, and this diluted antifreeze is preserved in the tank chamber 11, and the diluted antifreeze is transported to the tank chamber 10 by the request instruction from the tank chamber 10 and is supplied to an operating internal combustion engine 51 as cooling water. Cooling water is removed from the internal combustion engine 51 to fix the quantity of remaining water after the test, and the occurrence of rust of the internal combustion engine is prevented because of diluted antifreeze though the quantity of removed water is not uniform or the quantity of remaining water is varied by water drops in waterways.
