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.
The influence of oil sludge of concrete mixer truck is reflected in:
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. The engine power drops, the acceleration is not smooth, and the fuel consumption increases.
3. The engine exhaust emission becomes worse, which will also shorten the service life of spark plug, oxygen sensor and three-way catalyst.
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.
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.
