The filter has a little water, and the oil has been changed again, how to tell if the engine is floo

The oil dipstick, the oil level does not rise, and it is okay if it does not change color.

Yes.

When the air is filtered into the water, the engine will enter the water. It doesn't matter if the air filter is flooded, just replace it in time, don't let the water enter the engine through the air filter, otherwise it will affect the engine work. Solution:

stop the engine; Remove all spark plugs; Remove the air filter; Start the engine again to drain the water from the spark plug.

The role of an air cleaner.

The model of the air filter is different for each model, but the function is to filter. Engine ignition requires gas, first air enters the intake duct from the outside of the vehicle, filters through the air filter, then enters the throttle valve through the air flow sensor, and finally enters the engine combustion.

Therefore, the air filter element is particularly important, the air is mixed with some larger dust or particles that need to be filtered by the air filter element, the filtered air enters the throttle through the air flow sensor, and the remaining two links of the air flow sensor are responsible for monitoring the air intake through the throttle per unit time, and then the throttle opening is directly controlled by the accelerator pedal, so as to control the intake air flow, and finally the mixed air and gasoline are synthesized and burned in the engine.

No, it depends on how wet the filter is. There will be water in the spark plug after the engine is flooded. Disassembling the spark plug and hitting the car will cause water to spray out and the oil will change color.

No. First, the air cleaner element, located on the upper part of the engine cover. It is mainly for the air conditioner to circulate the air inlet filtration, if the rain is heavy, the raindrops may be directly inhaled, and the filter element will also enter the water state. It is not possible to prove that the engine is flooded.

Second, if it's parking, the water is flooded to that location. Since the engine air intake is lower than that position, the engine is generally flooded. But if it is not started, the water only enters the intake tract and does not enter the engine cylinder.

It's not a big deal. If you start the engine, it's really doomed.

Hello! The air filter inlet engine will not enter the water, the air filter is on the upper part of the engine cover, mainly for the air conditioning external circulation air intake filtration, if the rain is heavy, the raindrops may be directly inhaled, and the filter element will also enter the water, which cannot prove that the engine is water. The engine water is generally not to look at the engine room, but the main exhaust pipe water in, so the car is flooded or turned off when driving in the water, the vehicle cannot be started, to prevent water from entering the engine along the exhaust pipe.

The engine is a machine that can convert other forms of energy into mechanical energy, which was first born in the United Kingdom, and can be applied to both the power generation device and the entire machine including the power unit, such as: gasoline engine, aero engine. Hope it helps.

Air filtration inlet water, if severe, may enter the combustion chamberAs a result, the engine lacks fire and the cylinder pressure is insufficient. Water from the air filter generally does not get into the oil. In this case, it is recommended that you contact your local 4S shop for inspection and repair.

If you are not satisfied with the test results, you can complain to the car quality network. We will help you follow up with the manufacturer as soon as possible and wait for the manufacturer to deal with it.

Maintenance of the engine.

The core of engine maintenance is lubrication, and routine maintenance operations include cleaning, inspection, tightening, adjustment, replenishment, etc. Engine lubrication is primarily to reduce the friction between moving parts, reduce the wear of parts, and make them move freely, and its primary tasks include ensuring that the moving parts are fully lubricated, and replacing or compensating for the lubricating oil and filters.

Cleaning is the basis for preventing corrosion of parts, reducing wear of parts and reducing fuel consumption, and its primary tasks include the care of the surface of parts and the cleaning of the surface and interior of each assembly and parts. Inspection is to check the machine, to determine whether the operation of the parts is changed, whether there is deformation and damage, the primary operation content is to check the surface of the car assembly and parts, the operation and the tightness of the connecting bolts.

Yes.

If you keep the air cleaner peeled.

In the case of water ingress, even if it is not very serious, it can also lead to poor refueling, dullness and insufficient fuel supply to the engine. If it is so serious that even the cylinder is flooded, then when the engine is running, it is easy to have the phenomenon of "top cylinder", which will aggravate the wear and tear of the engine, and even scrap it directly. In general, we can't ignore the problem of water ingress into the air filter, and it needs to be replaced if necessary.

Air Filtration Considerations.

After opening the lid of the air filter assembly, we found that the color of the main air filter element of this car has been the same as the color of the dust on the body, although the filter element is not directly exposed to the outside of the car body, but through the transition pipe, high-level draft thick air duct and other channels, the main air filter element is relatively directly exposed to the air.

The filter paper of the main air filter element can block all kinds of magazines and dust suspended in the air outside the air intake system, ** It is not difficult to see that the surface of the filter paper of the main air filter element of this car, in addition to the color completely "gray", also adheres to a large number of fibers and dust on the outside of the filter paper.

You can observe the oil dipstick, if the water content in it is too high, the position of the lubricating oil will exceed the position marked on the ruler, or check the coolant of the engine, if the oil is found in the coolant, it means that water has entered.

Appearance, observe the oil dipstick, check the coolant, look at the color of the engine oil, where the engine oil is installed.

First, how to judge the oil water ingress.

1. If the amount of water contained in the engine oil of the engine is relatively large, the oil level of the engine will rise. At this point, we can judge by the dipstick.

Observe the oil dipstick.

Once the moisture content in the oil is too high, it is easy to tell that the level of the lubricating oil will be beyond the range marked by the dipstick.

2. Check whether the engine coolant contains engine oil. If some parts of the engine are damaged, then the engine coolant will enter the lubrication system, and oil is often found in the coolant, so checking whether the engine coolant contains oil is also a way to check whether the oil is ingressive.

Check if the engine coolant contains engine oil.

3. Carefully observe the appearance of the engine oil, and you can also easily judge whether the engine oil contains water. Engine oils that do not contain water have a translucent oil color, while oils containing water have an opaque brown or earthy yellow color.

Observe the color and appearance of the oil.

If the oil contains moisture, then after the engine has been running for a while, the oil will take on a milky white color with foam. This is due to the chemical reaction between the oil and the coolant under the action of high temperatures inside the engine, and the oil will be emulsified into an emulsion.

Second, what are the consequences of water ingress into the engine oil?

Light oil ingress will cause the engine temperature to be too high, heavy will lead to cylinder pulling pads and other failures, and more serious will lead to engine scrap. So, what are the principles that cause these failures?

1. Under normal circumstances, the water content in the oil is below 0 03, if the water content exceeds 0 1, the additives in the lubricating oil (such as antioxidants, cleaning and dispersing agents, etc.) will react with the water and fail, and the performance of the oil will decline.

2. Under the action of high temperature inside the engine, the oil will react chemically with the coolant, and the oil will be emulsified, and the lubrication effect of the oil will be reduced a lot.

4. After the oxidation resistance of the engine oil decreases, the organic acids generated by the oxidation of the engine oil will react with the water to form inorganic acids, and the acidic substances of the land punch skin will cause corrosion to the engine parts, thus making the parts rust or damaged.

When the oil enters the water, it will emulsify, that is, the oil will turn white. In addition, the amount of oil will increase.

If you open the oil cap (engine filler) and find milky white oil, it can be regarded as water ingress into the oil.

Check for extraneous first.

Whether there is an active oil leak in the department.

Pay special attention to whether there is oil leakage at the oil seals at the front and rear ends of the crankshaft. Oil leakage at the front end of the crankshaft can be caused by broken or damaged oil seals at the front end of the crankshaft, aging or worn contact surfaces between the crankshaft pulley and the oil seal. The oil seal at the rear end of the crankshaft is broken and damaged, or the oil return hole of the rear main bearing cover is too small, and the oil return is blocked, which will cause oil leakage at the rear end of the crankshaft.

In addition, attention should be paid to whether the rear end of the camshaft oil seal is leaking. The oil seal should be replaced in time if it is aging, broken and leaking. In addition, it is necessary to check whether there is leakage in each part of the engine lubrication system.

If there is oil leakage at the front and rear oil seals.

Even the front and rear cylinder head covers, front and rear valve lifter chambers, oil filters, oil pan gaskets and other organic oil seepage, but can not find obvious oil leakage, should check the crankcase ventilation device, clean the crankcase ventilation duct, especially check whether the PCV valve due to carbon deposition and gelation stagnation caused by poor work. Poor ventilation of the crankcase is likely to lead to an increase in pressure in the crankcase, resulting in multiple oil leaks.

If the joints of the oil filter and some oil lines are still leaking after being tightened, attention should be paid to check whether the oil pressure is too high and whether the oil pressure limiting valve is not working well.
