汽車廢氣 汽车废气
Bei der Verbrennung des Kraftstoffs im Motor mit Luft entstehen gasförmige Verbrennungsprodukte. Kraftstoffe bestehen aus einem Stoffgemisch organischer Stoffe, die aus dem Erdöl gewonnen werden. Dieses ist wie das Erdgas oder die Kohle aus ehemaligen Resten der Lebewesen in sedimentären Erdschichten in vielen Millionen Jahren entstanden. Die fossilen Brennstoffe enthalten chemisch gebundene Kohlenstoff-Atome.
