主　　题：gasoline intake valve deposits combustion chamber deposits 

摘      要：The cleanliness of gasoline is related to its components and *** commercial gasoline builds up deposits on the engine s injector,intake valve and combustion chamber,which can significantly lower the engine performance and influence exhaust gas *** this study,the intake valve deposits (IVD) and combustion chamber deposits (CCD) produced from combustion of fuel containing 21 v%—42 v% of aromatics and 8 v%—31 v% of olefins have been studied using Ford engine tests,and the characteristics of deposits were studied by IR spectroscopy,TGA and elemental analysis *** test results have shown that deposit formation depends on the fuel composition,especially the aromatic content in the *** is also observed that there are differences in the values of IVD and CCD measured by IR spectrometry and elemental analyses.
