When an engine is from stop and starting to accelerate, the digitally controlled fuel injection system would spray a slightly richer fuel mixture. This means that initially, fuel combustion becomes incomplete, until the engine picks up the speed, the intake air rushes faster to deliver enough oxygen and the combustion curve catches up with the richer fuel mixture till it reaches optimum.

It uses the same Type 311 as the Type 056A. They all use the same VDS, including second batch 054A.
Look at the other guy on the right, with his hands on something that looks like a thick rope going into a small square port. That's the Type 206 Towed Array Sonar.
The newest member of the family. DDG Kaifeng.
So fast. The 10th got another destroyer after 123 Huianan and 122 Tangshan.
The bottleneck has been how fast the PLAN or the unit in particular can adopt the ship and put it into operation.
The 10th, which had nothing but Type 051 Ludas, had a slow but drastic start to switch from 051 to 052D in one leap. 119 Guiyang was the seed vessel for them to learn and train on the vessel. Process wasn't easy, and the 10th could not accept new ships, and all the Dalian made 052D destined for them laid there in the shipyard.
But once the 10th moved from backwater to frontline unit, things begin to happen for the unit like a parabolic curve. The new ships began to be adopted, 120, 121, 122, 123, and now 124. They led their first ETF to the Gulf of Aden, and 120 Chengdu was their first unit to break past the first island chain into the Philippine Sea, in a recent escort of the Liaoning with 101 Nanchang, also another first for the unit. Impressive transformation within a few years.
For an unrelated detail, the zh wiki on the 052D has been updated, with the last destroyer of the batch to be 157 Zhuhai. So a destroyer will get the Zhuhai name but its going to the Sixth Destroyer Division and not the Second where its predecessor was based.
Remaining empty pennants left after all of the last of the remaining batch of 052D gets into service. This may help predict what the pennants and the numbers of the next batch of 052DL/052E will be from the next 5 year building plan.
1st Destroyer Division --- 109 to 114 will all be taken up by 055. During construction of the second block of 055, 112 Harbin (052) and 113 Qingdao (052) will probably be retired in the next coming years, freeing both their names and pennants for new destroyers. The question is whether 115 Shenyang (051C) and 116 Shijiazhuang (051C) will retire early or refitted. If retired early, 115 and 116 will be given to the new block of 055, and both destroyer names will be recycled for use with new destroyers. I do not expect new 052D to be added to this division.
2nd Destroyer Division --- Only one pennant left, 166. This is the pennant of retired 166 Zhuhai, the last Luda. +1 here for possible new 052X.
3rd Destroyer Division -- Only one pennant left, 135. +1 here.
6th Destroyer Division --- 158 and 159 will be left. +2 here.
9th Destroyer Division --- 176, 177, 178 and 179 are left. +4 here but the 9th might get only 055 in the future using the 10X and 11X pennants. So I am not sure if the 9th will be getting any more 052X in the future, and likely not at all.
10th Destroyer Division --- 125, 126, 127, 128 and 129 are left. +5 here.
So all in all, about 9 possible pennants left for 052X.
