Poor Heat Transfer Diesel Engine Due To Cooling Water Quality

Poor Heat Transfer Diesel Engine Due To Cooling Water Quality

(OP)
We have a problem about our Diesel Engine type MAK 453 A and MAK 453 C, in the last few years we dont use water treatment for our cooling water, consequently the engine can't perform, cooling water leak to combustion chamber due to cylinder head crack, engine over temperatur and cant achieve the peak load due to cooling water poor heat transfer

Our laboratory check result for cooling water:
Conductivity : 186.6 Ms/cm
Total Dissolve Solid (TDS) : 93.46 ppm
PH : 7.22
Turbidity : 6.14 NTU
Total Suspended Solid (TSS): 10 mg/l

Anyone can help us about this diesel engine type cooling water requirement? We want to compare with the real standard cooling water for diesel engine (With source is better)

Big thanks

RE: Poor Heat Transfer Diesel Engine Due To Cooling Water Quality

for engine coolant requirements, check with engine manufacturer.

regarding cylinder head crack, the cylinder peak pressures have likely been exceeded. check engine injection timing or other causes for high peak cylinder pressures.

then again, since water treatment is not used, has the engine coolant cooler been investigated? the case may be fouled tube or otherwise (poor heat transfer). poor water quality can also foul the metal lining inside the engine resulting in poor heat transfer and failed engine components.

good luck!

RE: Poor Heat Transfer Diesel Engine Due To Cooling Water Quality

The Diesels with which I am somewhat familiar use glycol + distilled water + additives, i.e. commercial antifreeze/engine coolant, as primary coolant, and seawater on the other side of the heat exchangers.

Are you saying you've been using plain water for primary coolant?
As in causing or allowing rusting of some very expensive cast iron parts?

Or not using heat exchangers at all?
With same effect on engine cooling channels?

Why?
