2. 15 TON
Engine coolant · · · a) When the engine coolant temperature is 140 ℉ (60 ℃ ) or lower
Engine coolant sent from the engine coolant pump ( ① ) is heated throuth the exhaust air
heat exchanger ( ② ) and the engine ( ⑧ ). The heated engine coolant returns to the engine
coolant pump ( ① ) by making a shortcut via the thermostat ( ④ , ③ ).
① : Engine coolant pump ⑧ : Engine ⑮ : Exhaust muffler
② : Exhaust air heat exchanger ⑨ : Gas mixer ⑯ : Exhaust water drain filter
③ : Thermostat (140 ℉ (60 ℃ ) ⑩ : Gas regulator ⑰ : Exhaust water drain hose
④ : Thermostat (158 ℉ (70 ℃ ) ⑪ : Electromagnetic gas valve ⑱ : Exhaust water drain trapper
⑤ : Sub heat exchanger ⑫ : Air filter ⑲ : Sub oil reservoir
⑥ : Radiator ⑬ : Engine coolant temperature sensor
⑦ : Engine coolant reserve tank ⑭ : Radiator cap
