求翻译：2#样品明显地不同于1#和3#样品，也不同于正常的在用柴油机润滑油样品，主要表现为积碳浓度过低，清净分散剂的作用微弱。是什么意思？

Sample 2 is significantly different from the 1 # and 3 # samples, but also different from the role of dispersant in the normal diesel engine lubricating oil samples, mainly coke concentration is too low, pure weak.

Sample #2 clearly different than 1 # and 3# sample, is also different than the normal diesel engine oil in the sample, leading to a low carbon concentration, purification of the dispersion effect is weak.

The 2# sample is obviously different with 1# and the 3# sample, also is different normally with is using the diesel engine lubricating oil sample, the main performance excessively is low for the carbon deposition density, the pure dispersing agent function is weak.

2# sample significantly different from the 1# and 3# samples, are different from normal diesel oil samples, mainly for low carbon concentration, weak detergent dispersant effect.
