A laboratory-scale gasoline injector deposit simulator was developed to simulate deposit formation, and the Fourier Transform Infrared (FTIR) technique was used to analyze the deposit formation mechanism under various wall temperature.

• 摘要建立了实验室尺度的沉积物生成仿真装置，并尝试以FTIR傅里叶转换红外线光谱法分析沉积物生成的化学机理，以探讨不同壁面温度下的喷嘴沉积物生成过程。
