<p>PURPOSE:To prevent the clear water cooler from being clogged and improve the cooling performance of the device by a method wherein the clear water cooler is incorporated into the delivery pipe of the pump to cool the clear water by the large amount of water passing through the delivery pipe. CONSTITUTION:When a diesel engine is operated, the pump 1 is operated, the rain water 6, pressurized by the pump 1, ascends through the delivery pipe 7, passes through the energy-saving type clear water cooler 25 and is discharged into a water tank 8. The clear water in the cooling jacket of the diesel engine 2 enters into a clear water path 40 in a cylinder 27 through the pipe 14 and an entrance 15, meanders in up-and-down and is cooled by the rain water 6 passing through a cooling pipe. Thereafter, the clear water returns into the diesel engine through an outlet port 16, the pipe 17, a pump suction port 18 and the pump 12.</p> |
