    Conclusions. 1. Among the elements that make up diesel C, there is a small part of sulfur. This sulfur in a complete combustion comes out in the form of sulfur dioxide (SO 2 ). A part of the SO 2, due to the excess air necessary for combustion, combines with oxygen giving rise to sulfur trioxide. SO 3.
