The characteristics of formaldehyde emissions in the diesel/methanol compound combustion system
柴油甲醇组合燃烧发动机的甲醛排放特性

A naturally aspirated diesel engine equipped with an independent methanol supply system is operated to investigate the effect of the oxidation catalyst on formaldehyde emission from the engine running in Diesel/Methanol Compound Combustion mode.The influence of speed,load,the position of the DOC (diesel oxidation catalyst) from the exhaust manifold,as well as the proportion of methanol in the fuel on the formaldehyde emission is studied.The relationship of formaldehyde and hydrocarbon (HC) emissions is also...
