High Silicon in Engine Oil Analysis - Machinery Lubriion

2 · High Silicon in Engine Oil Analysis. After oxygen, silicon is the most abundant element in the earth''s crust. Silicon does not occur naturally in elemental form but rather coined with oxygen in a compound called silica (silicon dioxide). Silica occurs in a free form (quartz, sand, etc.) or coined with a variety of metallic oxides, in which

Characterizing Diesel Particulate Filter Failure During …

2016/4/8· The alkalis have been observed to poison the alyst coatings in the diesel oxidation alysts and diesel particulate filters with respect to NO oxidation, or NO 2 make []. The reduction of the NO oxidation performance of the DOC and DPF can compromise the soot regeneration process in the DPF during normal vehicle operating conditions, resulting in higher soot loads in the DPF.
