Investigation on Emission Characteristics of Methanol Vehicle''s Aldehyde and Ketone Pollutants
甲醇燃料车醛酮类污染物排放特性研究

Investigation on the character and quantity of aldehydes and ketones emitted from methanol vehicle was implemented respectively by using high performance liquid chromatograph(HPLC) method.Experiments of vehicles equipped with and without three-way catalyst(TWC) under transient and steady mode were carried out.The emission results were compared with that of gasoline vehicle.The data showed that the efficiency of aldehydes and ketones emitted from methanol vehicle and gasoline vehicle were 22.53% and 48.95% w...
