Where the car passes through the depth of water, the car engine shakes

The most common cause of car shake is a dirty throttle or excessive carbon build-up in the fuel injector. When the carbon deposition inside the engine is excessive, the gasoline sprayed by the cold start fuel injector will be absorbed by the carbon deposition in large quantities, resulting in the mixture of cold start being too thin, making it difficult to start, in this case, only when the gasoline absorbed by carbon deposition is saturated, it is easy to get on the car, and the gasoline adsorbed on the carbon deposition after the car will be sucked into the cylinder by the vacuum suction of the engine for combustion, and the mixture becomes thick, and the combustible mixture of the engine is dilute and thick, causing idle shaking after cold start. The lower the temperature, the greater the amount of oil required for the cold start, and the more carbon deposits will affect the smooth cold start.

It is inevitable that the carbon deposit will be generated during the engine work, but when the carbon deposit is too much in the engine, it will cause the engine to work poorly and produce different failures. When there is too much carbon deposit inside the engine, the gasoline sprayed out by the cold start fuel injector will be absorbed by the carbon deposit, resulting in the mixture of cold car start is too thin, making it difficult to start, until the gasoline absorbed by the carbon deposit is saturated, it is easy to get started, and the gasoline adsorbed on the carbon deposit will be sucked into the cylinder by the vacuum suction of the engine after landing, so that the mixture becomes thick, and the combustible mixture of the engine is dilute and thick, causing idle shaking after the cold car starts. Workaround:

Clean the oil circuit and check whether the idle motor has carbon deposits and should be cleaned. Or for a period of time, drive at high speed in low gear and increase the engine speed, the purpose of which is to increase the air intake of the engine and the flow of gasoline, which helps to remove carbon deposits from the nozzle.

1. Oil road problems: mail road problems are generally caused by oil road blockage, resulting in poor oil supply, which is manifested as engine shaking, unstable standby speed, and stalling during driving; In addition, engine shake will also occur when the oil pump fails, and the oil pump problem should be judged by disconnecting the oil pipe and checking the flow rate and flow rate.

2. Circuit problems: check whether the right fit is accurate, and the general ignition is not normal is the right fit problem; Check whether the spark plug has aged, whether the gap is the same, and whether the gap has changed; In addition, if the distributor does not work properly, it will also cause the engine to shake.

3. Mechanical reasons: check the running status of the engine, whether there is abnormal sound, valve sound; Check the working condition of the belt and whether it is loose.

The problem is that there is a little water in the cylinder, the spark plug is wet, there is a lack of post, shaking, and there is a lot of water in, that is, the connecting rod is deformed, and this is about to decompose the machine [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, what's the reason for the delay in starting my car after passing through the water.

Why does the car shake so much after driving for a while? The old driver told the truth!

Common causes and solutions of car shaking:

1. Dirty air filter: The air filter is designed to protect the engine and reduce wear, and is generally replaced at about 10,000 kilometers.

2. High-voltage line breaking: High-voltage line breaking refers to the opening of the high-voltage wire core, which can affect the ignition and cause the engine to shake. Spark plug life:

The spark plug has a lifespan, and the ignition efficiency is significantly reduced after more than 3-40,000 kilometers, and can affect the ignition, which is the most common failure. Replace all the spark plugs.

3. Low idle speed: The engine idle speed value has been set in the computer, and when the number of revolutions is low to a certain range, the car computer will automatically adjust it. If the idle speed is too low and the jitter is beyond the control range of the computer, some cars have adjusting screws on the throttle to adjust the idle speed, and some cars can not adjust, this kind of car can check the idle valve, throttle, air flow meter, vacuum sensor, adjust the ignition time (car with distributor), you can increase the idle speed.

Low idle speed can occur even when the water temperature is low, so you can check and replace the thermostat.

4. Abnormal water temperature: The engine operating temperature has a normal range, and the ignition time will become early, the oil-gas mixing ratio will change, the oil viscosity will become thinner, and the lubrication performance will deteriorate when the water temperature is high. The general fault cause is the jitter caused by the lack of antifreeze, the thermostat cannot be opened, the fan does not rotate, and the temperature of the temperature control switch is inaccurate.

5. Fuel injector is blocked: The fuel injector of the EFI truck is a key component of automobile fuel injection, and the service life is very long, which can reach hundreds of thousands of kilometers. However, because there is gum in the gasoline, the fuel injection hole of the fuel injector will be blocked, so the amount of fuel injected by each fuel injector is inconsistent, resulting in the inconsistent work of each cylinder and causing the engine to shake.

The solution is to remove it and clean it.

6. Carbon deposition and oil scale blockage: The throttle, idle valve, and air intake hole will be blocked by carbon and oil scale after being used for a period of time, and the air intake will be poor, which will affect the stable idle speed and shaking. It is necessary to inspect and clean the above parts with cleaning agent, and there is no need to remove them for cleaning.

This is a normal sound, the car shakes after the water is pressed in the rain, the main reason is that the chassis of your vehicle is low, and the chassis of the vehicle is sealed, like a boat, so there will be a feeling of floating. The shaking is very strong, mainly because the exhaust is not smooth, the exhaust pipe is in the water, and other electrical appliances also see water, and the air intake system will also help. The feeling of not being able to supply oil The sound of idling is abrupt, this is because the car is in the water, and the water is assisted, of course, I feel bored with refueling.

Preferably in 1st gear with the throttle around 2500 rpm.

It should be caused by a lack of cylinder. Clean the spark plugs and injectors. It should be fine.

It is possible that a splash of water while wading has wet your dot system.

The weather is too cold, and the oil flows poorly. A normal phenomenon of cold starting. Changing a thinner winter oil can be improved.

Remember.

1. The reason for the shaking of the car after wading

When the car is flooded, a small amount of water enters the high-voltage line, and the engine air filter element is soaked in water, resulting in increased air intake resistance and water ingress into the combustion chamber, resulting in poor ignition system work, and the spark plug cannot be ignited in serious cases, and the car will even stall.

2. How to operate the car when wading

When the car needs to wade, you should lower the gear to 1 or 2 gear in advance and keep the throttle flushing through. When the water floods the exhaust pipe, the power will drop greatly, and when it is useless to refuel, you should keep the large throttle over the water, and do not change gears halfway. After crossing the water, it should be parked for neutral.

Hit the throttle a few times, drain the water in the exhaust cylinder, and press the brakes a few times when driving again, and then drive after the brakes are normal.

If there is an obstacle ahead when passing through a waterlogged road, the driver can maintain the engine speed by pressing the accelerator pedal in neutral gear and try not to collect the oil as much as possible to prevent the exhaust pipe from shutting down due to water inflow.

If the engine stalls on the way, you should never try to start the engine or gear trailer, and you can only tow it back to the repair shop in neutral gear for repairs.

What is the problem of car shake after wading, engine idle shake fault diagnosis generally has several situations, the most common reason for the formation of car flutter caused by severe engine carbon deposition, the engine has a general cleaning agent, which can remove carbon deposition without dismantling the oil to clean carbon sludge, which is very convenient to use, suspension differentiation does not clog together, and miscible with oil will not lead to delamination, better and safer cleaning of your engine.

Cars are prone to breakdowns after wading in water:

1. As the core part of the car, the engine is naturally indispensable for machinery and circuitry, so the engine is very afraid of being blistered. Once the engine is soaked in water, it can cause many problems, such as cylinder blowout, exhaust pipe corrosion, short circuit and so on.

2. ABS is a high-end device to ensure the stability of the braking direction of the car and prevent side slip and deviation. If the ABS is blistered, the mechanical ABS will be corroded, and the electronic ABS may be short-circuited. In any case, it is a very big hidden danger to your driving safety.

3. The airbag detonator is a device that detonates the airbag at the time of crisis, and most of the detonators detonate the airbag through gunpowder. If water enters the detonator, the gunpowder will naturally fail, so this is also quite dangerous.

4. Nowadays, many car owners like to install on-board computers for the convenience of driving, which naturally cannot withstand the baptism of water with high-end electronic instruments.

5. The dashboard of the car is a precision instrument device, and once the water enters, the dashboard will fail. As a result, the dashboard becomes waste.

Idle judder is most likely a problem caused by carbon deposits in the engine or carbon deposits on the throttle. If it is slightly shaking, and it is smooth and regular, it is considered normal jitter. Because when the engine is working, it is inevitable that it will shake.

For example, when the vehicle is started in cold weather in winter (also called cold start), the engine will shake, which is a normal phenomenon, because the engine lubrication effect is relatively poor at this time, plus the mixture is relatively thick, and the combustion is not sufficient.

The unstable idling of the car behaves as:

When idling, the engine shuddes and revs unevenly. The reasons are: blockage of the idle air measuring hole, poor working of the idle device, weak sparks of individual cylinder spark plugs, poor sealing of individual valves, air leakage of the intake manifold, too early or late ignition time, improper idle speed adjustment, etc.

When the engine idle speed is unstable, the idle speed should be adjusted first, if the fault can not be eliminated after the idle speed adjustment, the idle speed measuring hole and the idle air measuring hole should be checked whether it is blocked, if the measuring hole is blocked, it can be cleaned with gasoline or acetone and blown through with compressed air; If the measuring hole is not blocked, the engine speed should be stabilized at a certain speed, and the intake manifold or carburetor should be checked for air leakage in the middle and lower gaskets.

If there is air leakage, it can be eliminated by fastening screws or adding or subtracting gaskets. If the idle speed is unstable and accompanied by the decrease of engine power, the working condition of the spark plug, the sealing performance of the valve and the ignition time should be further checked, and the maintenance and adjustment should be carried out if necessary.

The computer tests it to see if the water temperature sensor data is normal [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Because when the car stops idling, the engine speed of the car becomes lower, and the temperature naturally drops, in addition, the car has a thermostat, no problem.

The thermostat automatically adjusts the amount of water entering the radiator according to the temperature of the cooling water, and changes the circulating range of the water to adjust the heat dissipation capacity of the cooling system and ensure that the engine works within the appropriate temperature range. The thermostat must be kept in good technical condition, otherwise it will seriously affect the normal operation of the engine. If the main valve of the thermostat is opened too late, it will cause the engine to overheat; If the main valve is opened too early, the engine warm-up time will be prolonged, and the engine temperature will be too low.

All in all, the role of the thermostat is to keep the engine from subcooling. For example, after the engine is working normally, the temperature of the engine may be too low if there is no thermostat in the winter. At this time, the engine needs to temporarily stop the water circulation to ensure that the engine temperature is not too low.

You can check whether water has entered the engine cylinder, if it does, it will cause damage to mechanical components such as engine connecting rods, and then cause the car to shake.

The air filter is dirty. Correctly determine filter characteristics. The characteristics of the filter are mainly filtration efficiency, resistance, transmittance, dust holding capacity, filtration air speed and treatment air volume.

If conditions permit, we should choose filters with high efficiency, low resistance, large dust holding capacity, moderate filtration wind speed, large treatment air volume, easy manufacturing and installation, and low filtration as much as possible. This is the need for economic analysis that comprehensively considers the one-time investment, secondary investment and energy efficiency ratio when selecting air filters.

It may be that the air filter is dirty, and the air filter is designed to protect the engine and reduce wear, and it is generally replaced in about 10,000 kilometers. It may also be a high-voltage line break: a high-voltage line break refers to the breakage of the high-voltage wire core, which can affect the ignition and cause the engine to shake, which can be measured with a multimeter.

Rain is a relatively common natural phenomenon, which is very common in our real life. However, the long-term rain is a very headache for all car owners. Because due to the rain, it will cause serious water on the road, and at this time, it will have a serious impact on the driving of everyone's vehicles.

It may cause us, the vehicle to appear wading. So what is the reason for the shaking of the vehicle after the car wades in the water? It may be due to the ingress of water into the high-voltage line, which leads to poor ignition.

At this time, we should pay attention to and pay attention to it, and actively go to the maintenance organization for testing. Identify specific causes and make specific measures. Of course, the risk of wading in the water, not only that, but there are many more serious consequences.

Some vehicles even stop directly in the water. For vehicles, the damage is very significant. So, but in fact, we must be doubly careful when wading in the water.

So how exactly do we do it? Let's take a brief look at it together. <>

The first is to slow down, and remember that when we need to wade through the water, we must slow down. Because if we drive too fast, then our car inertia is very large, at this time, coupled with the resistance of the water itself, it will have a great impact, causing the water to rush deeper and higher. Because of our vehicle systems, there is a greater danger.

Second, clarify the depth of water. In addition, we must not blindly wade through the water, we must confirm the depth of the water, whether we can pass safely, if the water depth is too high, do not blindly move forward, should choose other alternate routes. In this way, some unwanted effects are reduced. <>

I hope you can pay attention, after all, these things are closely related to us, if something really happens, it is also a big loss for us, and it is very unworthwhile. So you need to be cautious. Of course, I personally recommend that we should take a detour in the water, because there are many things that are not a**.
