What should I do if the engine of the big truck is flooded?

If the engine is only mixed with water vapor and enters water from the air filter, we only need simple treatment to clean the water vapor from the air filter, throttle and cylinder. Recently, the engine jitter has become more and more serious, and it has been repaired once, but the fault has not been eliminated. The staff helped him check, and it was judged that some cylinders of the engine were not working properly through abnormal sound and smoke from the exhaust pipe. Then the cylinder pressure of each cylinder is measured, and it is found that there are cylinders with low air pressure, some cylinders with bent connecting rods and heavy pistons. First of all, through analysis, it is considered that the cylinder may be submerged. In this case, it is necessary to check whether there is water in the cylinder. If there is water, besides draining water, check whether the engine has any abnormal phenomena such as trembling and abnormal noise during operation. If there is any abnormality, it is necessary to measure the cylinder pressure. If the cylinder pressure is too low, remove and service the engine. If there is no abnormal phenomenon, the accumulated water in the intake manifold should be treated. Secondly, check whether there is water in the oil pan. If there is water, replace the oil and oil filter. Third, check whether there is water in the transmission. If there is water, replace the transmission. Remind drivers and friends to avoid water in the cylinder when wading in the car. If there is deep water, take a detour. If the water is not deep, drive carefully and don't let the engine stall in the stagnant water. If you don't pay attention to the engine flameout where there is water, the engine cylinder will get water. Never start the engine again at this time and push the car through the stagnant water. @20 19
