- THIS paper evaluates a new class of detergents, specially effective in controlling sludge formation at the low or moderate temperatures most often encountered in passenger-car operation.This new Detergent C (a copolymer of lauryl methacrylate plus diethylaminoethyl methacry-late) has undergone extensive bench and laboratory tests in comparison with three other major classes of detergent. It exhibits, among other attributes:
-
1.
Complete solubilization of sludge.
-
2.
Complete carbon suspension under both wet and dry conditions.
-
3.
Residual detergency, as indicated by dispersancy in blotter tests under wet and dry conditions.
-
4.
Ability to prevent agglomeration and precipitation of sludge formed during oxidation of lubricating oils, with and without presence of water.
-
5.
Effective sludge suspension after 40-hr laboratory tests, and after several months of storage.
