The cooling water in the HT(high temperature) circuit cools the cylinder liners, cylinder heads and turbocharger. From the pump water is supplied to the engine manifold which is cast in the engine block. From the manifold the water is distributed to all cylinder liner sections and from each liner upwards through the cooling water channels in the liner collars. From the liner collars further into the cylinder heads. In the cylinder head the water is forced by an intermediate deck to flow along the flame plate, around the valves to the exhaust valve seats and up along the fuel injector sleeve. From the cylinder head the water is discharged via a connection piece into the discharge manifold.

The return water from the cylinder heads and turbocharger is supplied to the HT air cooler.

In the first stage of this cooler, most of the heat from the charge air is extracted. The LT circuit water cools the charge air in the second stage. The necessary cooling for the LT water is gained from a central cooler. By controlling the LT water temperature to the inter-cooler the correct charge air temperature can be obtained.
For preheating purposes, a heater circuit with a pump and heater are connected in the HT circuit before the engine. Before starting, the HT circuit is heated till about 60℃ by a separate heater The pre-heating of the engine is, prior of starting up and loading on HFO, of utmost importance.

75. From the passage we know that the charge air temperature was controlled by ____.
A. sea water from a central cooler
B. fresh water from a central cooler
C. fresh water from a HT circuit
D. fresh water from the LT circuit
76. The cooling water to cool the engine was forced ______ .
A. into the cylinder block and then upwards into the cylinder head
B. into the cylinder intermediate section and then upwards into the cylinder head
C. into the cylinder head and then downwards into the cylinder block
D. into the cylinder ends and then further into the cylinder intermediate
77. After the charge air is discharged into the HT air cooler, _______.
A. the charge air temperature will become higher
B. the charge air temperature will become lower
C. the HT water temperature will remain constant
D. the HT water temperature will become lower
78. Which of the following devices may be used to warm the engine prior to starting?
A. A high temperature cooling water system.
B. A low temperature cooling water system.
C. A central cooler.
D. The second stage cooler.
