A Study on Heat Loss of Low Speed Large Marine Diesel Engines

In this study it is' reviewed how to induce thermo-dynamically and mathematically the heat transfer coefficient formulas studied & reported for small high-speed internal combustion engines mainly. And using these formulas it is ensure to fit the calculation value with obtained combustion pressure data through experiment from low speed large marine diesel engine. Also it is analyzed that the measured temperatures of cylinder head, liner and piston crown those of the heat transferred wall area in combustion chamber with load variation. Accordingly, the characteristic of heat transfer has been grasped by analyzing variously a heat loss through combustion chamber wall which influence on confidence & economical efficiency belongs to basic items for internal combustion engines.
