Based on the research on the development status of methanol vehicles and formaldehyde testing technology at home and abroad, a comparison test was conducted between National V gasoline vehicles and methanol vehicles, and it was found that CO and THC emissions of methanol vehicles are lower than those of gasoline vehicles, NOx emissions are roughly the same as those of gasoline vehicles, and PM emissions are significantly lower; formaldehyde emissions are higher than those of gasoline vehicles. However, the existing testing methods cannot achieve direct and continuous testing of formaldehyde, and there is an urgent need to develop a direct measurement method for formaldehyde and corresponding testing equipment for in-use methanol-fuelled vehicles.
Key words: Methanol / Emission levels / Formaldehyde
