众所周知，汽车发动机废气中的物质随燃料而变化。因此，有必要了解现代发动机的碳氢化合物（HC）和羰基（醛和酮）排放量，特别是随着替代和可再生生物燃料的使用将增加。对于汽油，一种有前途的候选生物燃料是2，5-二甲基呋喃（DMF）。这项工作介绍了已使用气相色谱/质谱法（GC/MS）确定的主要碳氢化合物，并使用高效液相色谱法（HPLC）对加州空气资源委员会（CARB）方法1004规定的13种不同羰基化合物的排放进行了量化。试验在单缸直喷式火花点火（DISI）发动机上进行，转速为1500 rpm，λ = 1，点火正时恒定。对于GC分析，使用质谱鉴定了中等范围的HC。结果表明，未燃燃料（DMF）的排放占主导地位。其他主要排放物包括环戊二烯，甲基乙烯基酮，...
It is known that species in the exhaust gas of automobile engines vary with fuel. As such, there is a need to understand the individual hydrocarbon (HC) and carbonyl (aldehydes and ketones) emissions from modern engines, especially as the use of alternative and renewable biofuels is set to rise. For gasoline, a promising candidate biofuel is 2,5-dimethylfuran (DMF). This work presents the key individual HCs that have been identified using gas chromatography mass spectrometry (GC/MS) and quantifies the emissions of 13 different carbonyls as specified by the California Air Resources Board (CARB) Method 1004 using high performance liquid chromatography (HPLC). The tests were conducted on a single cylinder direct-injection spark-ignition (DISI) engine at 1500 rpm, λ = 1 and constant ignition timing. For the GC analysis, the midrange HCs were identified using the mass spectra. The results showed that unburned fuel (DMF) dominates the emissions. Other main emissions include cyclopentadiene, methyl vinyl ketone,...
