Since customers are becoming so sensitive about cabin odor, development of more effective deodorant filter is strongly required. Outside of vehicle, which most being disliked is diesel odor, therefore, analysis on this diesel gas and investigation to identity the ingredient for the main cause of the strong odor were executed, and found that acetaldehyde gas is the one. Therefore, identification of the chemical that adsorbs acetaldehyde gas with being impregnated in activated carbon was required, since activated carbon itself does not have ability of adsorbing acetaldehyde gas, and finally found appropriate chemical, vitamin Bx. At the end of this report, sensory evaluation result by twenty panelists with deodorant-type cabin air filter impregnated with vitamin Bx, and its efficiency for deodorant will be shown at the end of this report.
