Oil sludge is left by mineral oil for a long time, especially for engines with oil additives. If the oil sludge is too thick and you don't want to dismantle the engine, you can dismantle the valve cover and oil pan, soak it in diesel oil and brush it with gasoline. Especially the oil pump, you must dismantle it and clean it carefully, However, if the cover and oil pan are removed once, the cushion must be replaced. Generally, there are two simple cleaning methods without dismantling the engine. One is to add the cleaning oil added to the engine oil, and the other is to connect the machine to the engine and wash it circularly with a cleaning agent. If you want to thoroughly clean the oil sludge in the mixer engine, you must disassemble the engine and clean it thoroughly with an ultrasonic machine. Next, the small concrete mixer manufacturer will analyze how the concrete mixer cleans up the oil sludge.

混凝土搅拌车油泥影响体现在：

The influence of oil sludge of concrete mixer truck is reflected in:

1.冷启动困难，冷车怠速达不到规定的转速，严重时冷车怠速会熄火，热车后怠速低。

1. The cold start is difficult. The idle speed of the cold car cannot reach the specified speed. In severe cases, the cold car will stall at idle speed, and the idle speed is low after hot car.

2.发动机动力下降，加速不畅，油耗增加。

2. The engine power drops, the acceleration is not smooth, and the fuel consumption increases.

3.发动机尾气排放变差，同时也会缩短火花塞、氧传感器、三元催化器的使用寿命。

3. The engine exhaust emission becomes worse, which will also shorten the service life of spark plug, oxygen sensor and three-way catalyst.

4.积碳也会造成发动机的活塞环的卡滞，影响活塞环的密封性能，搅拌车造成机油消耗量增加，导致发动机烧机油，缩短了发动机的使用寿命。

4. Carbon deposition will also cause the piston ring of the engine to jam and affect the sealing performance of the piston ring. The mixer will increase the oil consumption, cause the engine to burn oil and shorten the service life of the engine.

先用一块破布大致上清理一下，然后稍微放一点汽油出来用毛刷惉上把剩下的不好清理的往下刷。刷完以后用换下的机油或者机油瓶里剩余的那点底子惉毛刷上边再给上一层油就行了。一般也不会专门去清理。拆下来先用洗洁精加水洗头遍，再用柴油洗再上机油，然后用布把多余的机油抹干净，上到车子上就可以了。平时用淘汰的儿童牙刷沾点机油刷前后齿的接触部位，尽量少而均匀，这样才少沾灰尘。拆下链条，把链条放入大的可乐瓶中，倒入适量清洗剂，(酒精五块一瓶，药店有售，可洗三次以上）盖上盖子，摇晃数次，取出装上。

First, clean it roughly with a rag, then put a little gasoline out, and brush down the rest that is not easy to clean with a brush. After brushing, just apply a layer of oil on the top of the replaced engine oil or the remaining base brush in the engine oil bottle. Generally, it will not be cleaned up. After removal, first wash your hair with detergent and water, then wash it with diesel oil, and then apply the engine oil. Then wipe the excess engine oil with a cloth and get on the car. Usually use the obsolete children's toothbrush with some oil to brush the contact parts of the front and rear teeth as little and evenly as possible, so as to reduce dust. Remove the chain, put the chain into a large coke bottle, pour in an appropriate amount of cleaning agent (five pieces of alcohol, sold in pharmacies, can be washed more than three times), cover it, shake it several times, take it out and install it.
