ONE CIRCUIT COOLING SYSTEM FOR GAS V-ENGINES
8/8
4 REQUIREMENTS OF THE ENGINE COOLING SYSTEM
The cooling system must be able to dissipate all the heat generated by the engine and keep the same at
the correct in all possible operating conditions.
The heat generated and the cooling temperature are reflected in the thermal balances of each engine.
The heat generated by the engine and shown on the thermal balance sheet is a value determined under
specific operating parameters and standard conditions, meaning that in real conditions the heat
generated by the engine may vary, depending on its operating conditions and on environmental
conditions. The cooling circuit should be sized taking into account these variations, as well as taking into
account the fact that the cooling system may well get dirty. KOHLER recommends having a
reserve capacity of 15%.
The cooling liquid must satisfy the requirements listed in product information IO-C-M-20-001. The cooling
circuit must be designed to take into account the fact that using antifreeze in the coolant reduces heat
transfer by 3% for each 10% of antifreeze added to the coolant.
The cooling circuit pressure must always be positive throughout the circuit and comply with all minimum
requirements laid down for each engine in product information sheets IO-G-M-60-002, IO-G-M-60-006,
IO-F-M-60-002 and IO-D-M-60-001.
The cooling circuit must have a certain flow rate, defined in product information sheets IT-G-A-20-007
and IT-F-A-20-005.
