There was a slight clicking sound when I got up in the morning, how to get back

Hello. Low oil pressure. Valve bottom rest is depressurized. It's okay to put pressure up.

There may be a problem with the starting motor

The most fundamental reason for the abnormal sound of the tappet is the low oil pressure, the aging or loosening of the foot glue and the excessive concentration of the mixture will cause the idle click, in addition, when the car starts cold, it will also idle click.

Aging or loosening of the foot glue: The foot rubber is the rubber block between the engine and the frame. Its function is to reduce the vibration and cushioning of the engine when working, and to have the effect of fixing the engine.

Once these feet are aged or loose, the engine will shake, and in severe cases, there will be a "click" abnormal sound, which only needs to be replaced with a new foot rubber.

Precautions for starting the car.

It is not advisable to start accelerating immediately after the automatic transmission car engine starts. It is best to let the engine idle for more than 30s, so that the oil of the automatic transmission can completely fill the oil cavity of each part, so that the automatic transmission can maintain a good working condition, and then start driving in gear.

If it is a cold car state, especially in the cold area in winter, after starting, ensure that the lubricating oil in the engine and automatic transmission has enough heating time, and wait for the temperature of the engine coolant to rise to more than 40 degrees, and the engine idle speed is normal before starting the operation, otherwise, it will increase the consumption of the car painting when starting, resulting in abnormal phenomena such as starting or rapid acceleration.

Oil temperature and quality reasons, as well as engine cleaning valves.

1. When the car is parked for a day, the lubricating oil of the engine basically flows back to the oil pan, when the engine starts cold, the oil pump can not establish the oil pressure in the first time, and the oil film is formed between the parts, especially the valve inside the cylinder head (upper part), which can not be lubricated during the cold start, whether it is a hydraulic tappet or a mechanical rocker arm, there will be a certain valve clearance, resulting in a clicking sound. When the engine runs for a period of time, the oil pressure builds up the oil film, the oil temperature rises, and the sound of "da-da" disappears after the engine works normally (note, if the engine has been clattering when the car is hot, go to the repair shop for testing as soon as possible).

2. In addition to the reason for the oil, there is another element of the engine that will also make a clicking sound - the carbon canister solenoid valve (cleaning valve), its function is that when the engine starts, the solenoid valve installed between the carbon canister and the intake manifold is opened, and the gasoline vapor adsorbed by the carbon canister is brought into the cylinder by air to participate in combustion under the vacuum of the intake manifold. This not only reduces emissions, but also reduces fuel consumption, which also makes a clattering sound during operation. (Added:.)

Oil quality problems sometimes make the engine clatter) Therefore, the clatter sound of the car cold start is not a fault, if the car is hot when this abnormal sound needs to be paid attention to, some luxury car engines will also appear when the cold start of this phenomenon.

3. Engine "tempering" failure. When the car slows down and collects the oil, there is a "poof" sound, which may be the engine "tempering" failure, which is usually called the engine "fire", too much carbon deposition on the valve or the wrong timing of the valve will produce abnormal noise, cleaning the carbon deposit on the valve or adjusting the timing of the valve.

4. The engine lacks cylinders, a cylinder does not work, the engine will be unbalanced and produce abnormal noise, and it is also accompanied by the violent shaking of the engine, insufficient power and other faults, which may be the fault of the ignition module, spark plug and fuel injector, and the corresponding accessories can be replaced.

5. The engine timing adjustment is wrong. If there is a mistake when replacing the timing belt, such as the timing adjustment is wrong, there is likely to be a more serious metal knocking sound inside the engine, and its direct impact is the top valve (the valve is crooked), at this time, you can only replace the valve and other related accessories, and the engine needs to be disassembled.

What is the problem with the "click" sound when the car idles?

If the vehicle has this phenomenon between the cold car state and the hot car state, and it lasts for about 3 minutes, it is not a problem, but the cold car valve clearance is large and the lubrication is poor. If there is a sound you describe during acceleration, it is not a problem with the valve sound.

1. There may be a slight detonation;

2. It may be a slight knock on the cylinder, and the ring is stuck;

3. It may be that the cylinder wall has been introduced, and it is necessary to find an experienced technician to check it.

When the engine starts cold, the oil pump can not establish the oil pressure at the first time, and the oil film is formed between the parts, especially the valve inside the cylinder head (upper part), which can not be lubricated during the cold start, whether it is a hydraulic tappet or a mechanical rocker arm, there will be a certain valve clearance, resulting in a clattering sound. When activated.

Hello. Low oil pressure. Valve bottom rest is depressurized. It's okay to put pressure up.

There's nothing wrong with this, it's the sound that the car relay makes when it's working.

A relay is an electrical control device. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in the control circuit of automation, it is actually a kind of "automatic switch" that uses a small current to control the operation of a large current.

Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.

Working principle: When the input quantity (such as voltage, current, temperature, etc.) reaches the specified value, the output circuit to be controlled is turned on or off the electrical appliance. It can be divided into two categories: electrical (such as current, voltage, frequency, power, etc.) relays and non-electrical (such as temperature, pressure, speed, etc.) relays. It has the advantages of fast action, stable work, long service life and small size.

It is widely used in power protection, automation, motion, remote control, measurement and communication devices.

The foot glue is aging or loose. The foot glue is the rubber block between the engine and the frame. Its function is to reduce the vibration and cushioning of the engine when working, and to have the effect of fixing the engine.

Once these foot glue appear aging or loose, the engine will shake, and in serious cases, there will be a "click" abnormal sound, which only needs to be replaced with a new foot glue.

Precautions for driving a car.

When driving a car, the driver's hands should be on the left and right sides of the steering wheel, which corresponds to the 9 o'clock and 3 o'clock position of the clock. Because it can give the driver better control the steering wheel when cornering, and it is conducive to the airbag to pop in case of danger.

Be sure to wear a seatbelt when driving a car, not only to prevent you from being fined for taking pictures with electronic eyes, but mainly to better protect yourself in case of danger. The harness needs to fit snugly against the body from the shoulders to the waist and then through the hips as far down as possible.

The reason for the engine, the rattling sound is generally the sound of metal impact caused by the sound of the valve ringing, excessive valve clearance or wear, etc.

The reason for the tires, if the car is driving on the highway, if you open the window, you can clearly hear the sound of "da-da" from the body, at this time, it may be that the tire is embedded with stones, and you can stop on the right side to check the tire if it is safe.

1. Many new car owners will suspect that the car engine has abnormal noise when they open the front cover when the car is idling after the first warranty inspection service is returned (because before going to maintenance, they are operating in the cab of the car, and they can't hear the sound of the engine under the front cover when it is normal operational. At present, this sound is heard because in the situation of idling and opening the front cover to find the engine sound, it is natural to hear the sound of the engine operating normally. If you can't hear it in the car, it's not too loud, it's usually the sound of the valve or the fuel injector.

The canister solenoid valve also has this sound, but the sound is brittle. There is a way to distinguish, (Wilf energy-saving engine oil is to give some oil at idle speed to see if the frequency changes, if the frequency does not change, it is the sound of the solenoid valve, if the frequency changes, it should be abnormal sound at the valve.) If you can't hear it clearly in the car, the problem is not big, the vehicle will have a corresponding clicking sound, one is the sound of the fuel injector working, the other is the valve part, and there is a similar sound, which is the sound of the timing chain, but it is different from the clicking sound, there is a Gragra sound.

2. When the general car starts cold, the engine sound will be slightly louder than that of the hot car, as long as the sound sounds uniform and soft, not harsh, there is generally no problem. This is due to the fact that the gap between the cylinder wall and the piston is not yet optimally sized during cold driving, and the lubrication of the oil is not sufficient. Usually when the engine block temperature reaches about 95 degrees, the sound will return to normal.

3. The reason for the oil. Inferior engine oil or not changing the engine oil for a long time, lack of engine oil, etc., can easily lead to increased friction between the valve and the duct and the hydraulic tappet, etc., so that the various sounds in the engine are louder.

4. If you are still not at ease through the above investigation, it is recommended to go to the nearest 4S or auto repair shop to check to confirm the cause of the failure.

Abstract Two aspects, after the power on the car inside the center console of the sound is normal, this is the air conditioning system servo motor in the sound of work, equipped with automatic air conditioning in the car after the car is energized in the center console will appear to make a clicking sound, you do not need to worry, this is not a fault, this is a normal phenomenon.

2.Cars are air-conditioned, and air conditioning is a very important comfort configuration on the car.

What's the deal with the clicking sound of the car when it is powered on?

Hello, I'm glad for your question, here is still in the query and analysis of even two aspects, after the power on the car's center console inside the sound of the sound of the car is normal, this is the air conditioning system servo motor in the sound of working, equipped with automatic air conditioning of the car after the car is powered on the center console will appear da da sound, you don't need to worry, this is not a fault, this is a normal phenomenon. 2.Cars are air-conditioned, and air conditioning is a very important comfort configuration on the car.

Hello not before.

Feels like a relay issue.

Click-clatter.

Feel under the steering wheel.

When you adjust the air vent switch of the air conditioner, a sound appears.

It is the sound of the servo motor of the air conditioning system working, and the center console of the car equipped with automatic air conditioning will appear to click after the car is energized.

When adjusting the air outlet switch of the air conditioner, the sound is normal.

It has nothing to do with relays, steering wheels, etc., but it didn't have before.

This is normal, don't worry

It is normal for the car to have a clicking sound after it is turned off.

That's because the temperature of the engine will rise correspondingly after continuous high revolution, the engine is very hot, and when the cylinder block temperature is uneven, the temperature of the cylinder block is uneven, which reduces the friction sound between the metal joints for cooling and contraction.

Before looking for a fault, you should first rule out whether it is the sound of the engine cooling fan. If there is nothing abnormal in the car, it is a normal phenomenon, the reason why there is a clattering sound is because the temperature of the engine will increase accordingly after continuous high revs, resulting in a very hot engine, when the temperature of the cylinder block is unevenly reduced after parking, resulting in cooling and contraction between the metal joints, the clattering sound is the friction sound between the metals, especially for the old car.

There is a clicking sound after the car turns off

1. The temperature of the engine will increase accordingly after continuous high rotation, resulting in the engine being very hot, and when the temperature of the cylinder block is unevenly reduced after parking, it will cause the cooling and contraction between the metal joints, and the sound of clicking is the friction sound between the metals, especially for the old car.

2. The sound of friction between the joints of some metal parts in the engine due to cooling and shrinkage.

3. If it is an engine with a turbine, it may also be the sound of turbine cooling, which is the sound of metal heat expansion and contraction.

4. If there is any of the above conditions, go to the relevant maintenance point for engine cleaning.

Hello, the car starts with abnormal noise, and the reasons why there is no abnormal noise when it runs fast are: 1. The brake disc is oxidized and rusty; 2. The pattern of the wheel is mixed with foreign objects; 3. The suspension is aging, and some supporting parts in the suspension fail; 4. The cylinder pressure of the engine does not reach the best state when starting; 5. The engine transmission belt is too hard when the car is cold. How to start the car:

1. Adjust the seat before driving to ensure that your feet can step on the clutch, brake and accelerator; 2. For manual transmission cars, when starting with a gear, the clutch must be stepped on the end, the right foot is put on the accelerator, and the left light is played; 3. The clutch of the left foot should be lifted to nearly half and stop for a while, and the handbrake should be released in time when the vehicle is shaking; 4. Tap the accelerator, release the clutch when the car moves forward, and add the accelerator to start; 5. For automatic transmission cars, adjust the seat before starting, step on the brake, push the gear to the D position, and start slowly with refueling. I hope it can help you, I hope you can give a thumbs up, thank you for your support and trust in the platform, thank you.
