Sludge control

Although p oly (a-olefin) s (PAO) and esters are the prominent synthetic base stocks for automotive appfications, combinations of the two are becoming the choice in offering a balance of properties such as additive solubility, sludge control, and elastomer compatibility (34). [Pg.245]

Further fractionation of the solids was effected by extraction with a chloroform-methanol mixture to separate the lipids. The control sludge and the fractions were tested for acetogenic activity at twice their normal equivalent sludge concentrations to ensure production of measurable quantities of acetic acid. The data plotted in Figure 4 indicate that the lipid fraction contains the substrates responsible for the rapid increase in acetate following addition of raw sludge. Acetate increased at approximately the same rate as the raw sludge control. No acetate was observed... [Pg.46]

Over the years, detergents have found equally important usage in many other types of lubricants, including gear oils, farm tractor hydraulic fluids, automatic transmission fluids and industrial oils. The performance properties that detergents impart to these lubricating fluids include rust and corrosion prevention, improvement in lubricant elastomeric seal compatibility, enhancement of sludge control under oxidative conditions and improvement of wet clutch and wet brake friction level and stability.
