采用热重/差示扫描量热法（TGA/DSC）对柴油机燃用含水量为0%、5%、10%和15%（体积分数）的乳化柴油和20%棕榈油甲酯（POME）时的气缸盖积碳存款进行了研究。在单缸直喷式柴油机上，对每种试验燃料在2500 rpm恒转速下进行了25 h的存款积累过程。使用TGA系统，然后与元素分析以及红外光谱进行显微观察。已经发现，随着燃料中水的增加，将形成较少的芳香族和较少的反应性沉积物。因此，这种分析方法可用作检验燃烧室内碳存款稳定性的指标，该指标可证实所接受的特定燃料的适用性。
This paper aims to evaluate the cylinder head carbon deposit from diesel engine fuelled by four samples of diesel fuel emulsions containing 0%; 5%; 10% and 15% vol. water and 20% Palm Oil Methyl Ester (POME) were subjected to thermogravimetric analysis (TGA/DSC) in air medium. The deposit build up processes were performed on a single-cylinder direct-injection diesel engine for period of 25h for each set of test fuel under constant speed 2500rpm. The TGA system was used and then correlated with elemental analysis as well as infrared spectra for microscopic observations. It has been found that, as the water increases in fuel, less aromatic and less reactive of deposits would be formed. Therefore, such method of analyses can be used as an indicator to verify the stability of carbon deposit inside the combustion chamber that could substantiate the applicability of a particular fuel to be accepted.
