Abstract
Engines are very important power units in aircraft and automobiles. After running for a period of time, carbon deposit formed on the surface of the engines, which will increase energy consumption, reduce the performance of the engines, and pollute the environment. Therefore, it is important to understand the morphology and chemical composition of carbon deposit to avoid the formation of carbon deposit. In this paper, the surface morphology and elemental composition of carbon deposit were studied by scanning electron microscope and energy dispersive X-ray spectrometer. In addition, the chemical groups of carbon deposit were explored by thermogravimetric and Fourier transform infrared spectroscopy. The results show that the carbon deposit originates from fuel oil and lubricating oil and their additives, engine matrix, and air. Carbon deposit is composed of organic components, inorganic components. The organic components include saturated hydrocarbons, unsaturated olefins, alcohols, phenols, aldehydes, ketones, acids, and esters.
