Carbonyls emission from ethanol-blended gasoline and biodiesel-ethanol-diesel used in engines
AbstractDetailed carbonyls emissions from ethanol-blended gasoline (containing 10% v/v, ethanol, E-10) and biodiesel-ethanol-diesel (BE-diesel) were carefully investigated on an EQ491i gasoline engine equipped with a three-way-catalyst (TWC) and a Commins-4B diesel engine. In engine-out emissions for the gasoline engine, total carbonyls from E-10 varied in the range of 66.7–99.4mgkW−1h−1, which was 3.1–8.2% less than those from fossil gasoline (E-0). In tailpipe emissions, total carbonyls from E-10 varied in the range of 9.2–20.7mgkW−1h−1, which were 3.0–61.7% higher than those from E-0. The total carbonyls emissions from BE-diesel were 1–22% higher than those from diesel at different engine operating conditions. Compared with fossil fuels, E-10 can slightly reduce CO emission, and BE-diesel can substantially decrease PM emission, while both alternative fuels increased slightly NOx emission.
