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.

混凝土攪拌車油泥影響體現在：

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

1.冷啟動困難，冷車怠速達不到規定的轉速，嚴重時冷車怠速會熄火，熱車后怠速低。

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.發動機動力下降，加速不暢，油耗增加。

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

3.發動機尾氣排放變差，同時也會縮短火花塞、氧傳感器、三元催化器的使用壽命。

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

4.積碳也會造成發動機的活塞環的卡滯，影響活塞環的密封性能，攪拌車造成機油消耗量增加，導致發動機燒機油，縮短了發動機的使用壽命。

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.

先用一塊破布大致上清理一下，然后稍微放一點汽油出來用毛刷惉上把剩下的不好清理的往下刷。刷完以后用換下的機油或者機油瓶里剩余的那點底子惉毛刷上邊再給上一層油就行了。一般也不會專門去清理。拆下來先用洗潔精加水洗頭遍，再用柴油洗再上機油，然后用布把多余的機油抹干凈，上到車子上就可以了。平時用淘汰的兒童牙刷沾點機油刷前后齒的接觸部位，盡量少而均勻，這樣才少沾灰塵。拆下鏈條，把鏈條放入大的可樂瓶中，倒入適量清洗劑，(酒精五塊一瓶，藥店有售，可洗三次以上）蓋上蓋子，搖晃數次，取出裝上。

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.
