What are the common sense of vehicle maintenance, and is it a problem with engine oil that is noisy

There are several reasons for increased engine noise:

1. Failure to change the oil on time The viscosity of the oil does not match.

The viscosity of the engine is too high in the cold start or low temperature working state; At normal operating temperatures, the viscosity is too low. If one of these two situations occurs, it may cause a series of problems such as engine noise and insufficient power.

2. There is it in the cylinder.

Carbon deposits. If you don't change the oil on time, the old oil will become thinner and thinner, so the carbon will accumulate more and more. The oil is thin and easy to channel the oil, resulting in more and more carbon deposits and a lot of power loss. When changing to a new oil, the engine does not adapt to the viscosity of the oil, probably.

Pull up. speed, which in turn causes the engine to be noisy.

3. Valve leakage.

The valve leakage sound is outside the valve door, which is more significant at high load and low speed, and the sound increases with the increase of load.

Engine compartment. Soundproofing issues.

If you listen to the engine working normally from outside, and feel that the noise is too loud when you sit in the car, it means that your vehicle is poorly insulated.

Appear. Detonation.

, ie. Spark plug.

After flashover, the phenomenon of spontaneous combustion occurs at the end of the combustible mixture, and the spark plug ignites the mixing.

The flame center formed by the gas is the new flame center formed by the spontaneous combustion of the terminal gas mixture, in the opposite direction, and propagates at the speed of impact, producing a sharp one.

Knock the cylinder. sound, increasing engine noise.

First of all, we need to know that vehicle maintenance is divided into routine maintenance, and.

Major maintenance. Routine maintenance is generally carried out once every 5000 kilometers or so, and the oil needs to be changed.

Oil filter.

The major maintenance of 60,000 kilometers is carried out once, and the oil is changed respectively

Machine filter. Air filter.

Gasoline filters, air conditioning filters, spark plugs,

Brake fluid. Transmission fluid.

In addition, while we do routine maintenance, the standardized maintenance process also includes tires.

Tread. Inspection, chassis inspection, steering wheel,

Brake pads. Brake discs.

Suspension swing arms, floor plates, fluid levels, light checks, etc.

We also need to know that the maintenance interval of some wear parts:

1. Engine oil, 5000 10000 kilometers to change once, some oil, the service cycle can be longer.

2. Steam filter, air filter, air conditioning filter, replace once every 20,000 kilometers.

Antifreeze. 20,000 km or every two years.

4. The spark plug is changed once every 30,000 to 40,000 kilometers, and the spark plug is aging, which is also one of the reasons for the lack of engine power.

5. Transmission oil, 50000 60000 kilometers to replace once, different types of transmission oil should not be mixed.

6. Brake fluid, 20000 40000 kilometers to replace once, different types of brake fluid shall not be mixed, otherwise right.

Brake system. There is a certain impact.

Steering assistance. liquid, 20,000 40,000 kilometers to change once, should not be mixed.

The above are some common maintenance common sense, change the oil, air filter.

And. cabin air filter.

They are all relatively simple, hands-on friends, you can do it yourself, you can save the labor cost of the repair shop. All kinds of filters are available online and are also cheaper than repair shops.

There is no absolute relationship, the car has been used for a long time, the gap between the various parts is loosely matched, the engine energy consumption increases, the door seal is aging, and the sound insulation is not good, which will lead to louder noise, the car is a consumable, if you want to have good sound insulation, it is difficult for the general scooter to do.

Hello, the general vehicle for a long time, the tire noise will be louder, if the engine noise is loud, it is related to the oil.

The so-called car maintenance refers to maintaining and restoring the technical performance of the car, ensuring that the car has good usability and reliability, timely and correct maintenance will prolong the service life of the car, improve the safety performance, save money and avoid many troubles of repairing the car. Therefore, timely and correct maintenance of the car is an important part of prolonging the service life of the car and ensuring driving safety.

The often said car maintenance is mainly from the work of maintaining the good technical condition of the car and prolonging the service life of the car. In fact, its content is wider, including car beauty care and other knowledge, in summary, there are mainly the following three aspects:

1. Body maintenance.

Car body maintenance is also commonly known as car beauty. The main purpose is to remove all kinds of oxidation and corrosion outside and inside the car, and then protect them to highlight the car as much as possible"Beauty"。It mainly includes:

Car paint maintenance, cushion carpet maintenance, bumper, skirt maintenance, instrument panel maintenance, electroplating processing maintenance, leather and plastic maintenance, tire, wheel maintenance, windshield maintenance, chassis maintenance, engine appearance maintenance, etc.

2. In-car maintenance.

The purpose of in-car maintenance is to let the car travel hundreds of thousands of kilometers without major repairs and ensure that the car is in the best technical condition. However, with the development of science and technology, energy-saving maintenance products have been paid attention to by the majority of car owners, adding anti-wear agents can save fuel, reduce the failure of the machine, and prolong the service life of the machine. It can reduce failures by 75% and greatly extend engine life by 2---5 times.

It mainly includes: lubrication system, fuel system, cooling system, brake system, carburetor (injector) maintenance, etc.

3. Refurbishment of the car body.

Such as the diagnosis and treatment of deep scratches, the repair of multi-material bumpers, the repair of hard injuries of wheel hubs (covers), the refurbishment of leather and chemical fiber materials, and the refurbishment of engine colors.

Car maintenance is divided into two categories: regular maintenance and unscheduled maintenance, and regular maintenance includes daily maintenance, first-level maintenance, and second-level maintenance; Non-scheduled maintenance includes running-in period maintenance and seasonal maintenance. The main tasks of car maintenance are nothing more than cleaning, checking, tightening, adjusting and lubricating.

1. Clean the water tank regularly. Rust and scale can limit the flow of coolant in the cooling system, reduce heat dissipation, and cause engine overheating or even engine damage. Therefore, it is necessary to clean the tank regularly to remove rust and scale from it.

2. Replace the oil and filter element regularly. The oil quality of any quality grade of lubricating oil will change during use, in order to avoid the occurrence of failure, the oil should be changed regularly in combination with the use conditions, and the oil volume should be moderate, generally the upper limit of the oil scale is better).

3. Keep the crankcase well ventilated. Most gasoline engines are now equipped with PCV valve crankcase forced ventilation devices), but contaminants from the blow-by gas can be deposited around the PCV valve and may clog the valve. Therefore, contaminants must be removed regularly from around the PCV valve.

4. Use lubricating oil of appropriate quality grade. For gasoline engines, SD-SF gasoline engine oil should be selected according to the additional devices and conditions of use of the intake and exhaust system; Diesel engines should be selected according to the mechanical load of CB-CD grade diesel engine oil, and the selection standard shall not be lower than the requirements specified by the manufacturer.

5. Clean the fuel system regularly. Regular cleaning of the fuel system to control the formation of carbon deposits keeps the engine in top condition.

6. Maintain three filters. The three filters are air filters, oil filters, and gasoline filters. The three filters filter the air, oil and gasoline on the automobile engine, so as to protect the engine and improve the working efficiency of the engine.

7. Clean the crankcase regularly. During the operation of the engine, the oxides of high-pressure unburned gas, acid, moisture, sulfur and nitrogen in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall, and mix with the metal powder produced by the wear of the parts to form sludge. Therefore, the crankcase should be cleaned regularly to keep the inside of the engine clean.

Car maintenance is mainly to change the three filters, and there is also to change the oil, which can solve the problem of high engine noise.

The maintenance is mainly the oil filter.

Others, such as cleaning the throttle, need to be carried out according to the condition of the car.

If you want to solve the problem of loud engines.

You can choose a better full compositor.

This may work better.

<><Is it normal for a car to become louder after maintenance?

Does everyone know? After the maintenance and oil change, especially after changing the engine oil of different types, many car owners report that the noise of the engine will become louder! Sometimes we may have questions; Is it a fake phone when the noise gets louder?

Actually, it's not necessarily the reason. The master believes that after changing the oil for maintenance, the noise of the engine becomes louder, and this phenomenon cannot be generalized.

Let's start with a brief introduction! Carbon deposits are like blood clots on the human land, but if it is a little, it will not affect much, but if there is more, it will be problematic. In fact, the car is the same, the carbon deposit has become more, the intake and exhaust valves, cylinder edges, piston tops, spark plugs, etc. will be greatly affected, because the carbon deposits have affected so many places, in the process of driving, if you want to have the same power as a new car, it can only be a little more at the accelerator, and the speed will definitely increase, and the noise will not be able to change the noise.

That's right! At present, most of the engine levels that can be bought in general life cars are 3-cylinder, 4-cylinder, and 6-cylinder. As you all know, the smaller the number of cylinders, the more pronounced the vibration of the engine itself, and the more obvious the vibration, the louder the sound transmitted to the cabin.

Therefore, when the parts that dampen the engine age, the damping effect will be reduced accordingly, and the vibration and noise felt by the passengers sitting in the car will also become larger. These deposits can increase the compression ratio of the engine and increase the tendency to detonation; The red-hot state of carbon deposits in the cylinder is also easy to cause premature ignition, such as falling into the cylinder will aggravate the wear of the cylinder and the active number of plugs, and will also accelerate the pollution of the engine oil. Secondly, too much oil increases the stirring resistance of the crankshaft linkage, and the noise will also increase.

It is true that the oil labels do not match. We all know that engine oil and fuel are also labeled, and different grades of engine oil should respond to different use environments and needs. Most areas of our country can use 5W-30 40 type oil all year round, like the first liquid brigade in some extremely cold or high temperature areas, you need to choose winter or summer oil according to the vehicle use environment.

If an untimely oil type is used, it is possible to have poor engine operation, increased noise, difficulty starting, high temperatures, etc.

All in all, many reasons such as aging or loose engine belts, poor fuel quality, and exhaust pipe system failure will cause the car engine to become more and more noisy and increase fuel consumption. When the problem arises, we must find the car maintenance master for the first time to find the problem and repair it in time, so as not to cause greater damage to the engine.

There are many reasons for loud noise in the car, and engine oil is one of them. Lack of oil, mismatch of model, and failure to replace maintenance over the cycle will cause poor engine lubrication to varying degrees, thereby aggravating engine wear, and the noise of the engine will increase significantly. In addition, the interior noise may also be wind noise and tire noise, of which the wind noise is large in addition to the design reasons, should minimize any modification on the appearance, because this will destroy the vehicle drag coefficient of the car, and then affect the stability and quiet performance of the whole car in the aerodynamic range, wind noise also need to check the closure of windows, sunroofs and other positions.

Tire noise is usually related to tire selection and tire wear, the noise performance of tires with different patterns and widths is different, and the difference in use time will also cause a gap in noise performance.

Finally, after excluding the above reasons, you can try to strengthen the sound insulation and noise reduction treatment for the whole vehicle, mainly the engine compartment, four doors and the trunk position to install sound insulation material interlayer, pay attention to the selection of fire and temperature resistance level of sound absorption materials.

Hehe, the problem you said should be analyzed from many aspects, first of all, your good habit of regular maintenance of the car is worthy of --- praise!

The noise of the cold car is related to the degree of wear and tear of your car engine and the oil you use, when the new car has a good clearance between the parts, the noise is naturally small, when running a certain kilometer, especially when often overloaded or choose to use unqualified oil, the parts and components will naturally increase after wear, and the noise will appear to be louder. Suggestion: It is best not to overload your car (especially often); Change the oil with the right viscosity seasonally; It is best to go to a 4S shop to change the oil; If you feel that the cost of the 4S shop is higher, you can buy a guaranteed brand of engine oil and go to the general maintenance point (appropriate cost) to replace it; It is not recommended to change the oil or filter in the roadside maintenance shop (if the oil quality is not guaranteed, the cost of the filter is three or five yuan) [If the oil quality is not good, the damage to the engine will be great, and there is nothing wrong with the cold surface, once it works in a high-temperature environment, the inferior oil can not achieve the due lubrication effect, and unconsciously accelerate the wear of the engine.

Remember! I wish you a safe drive and good luck.

After the car changes the oil, the engine becomes louder?

Is the engine noisy or **noisy? Don't listen to those people's nonsense. As long as you don't add fake oil, you can.

There are also special ingredients that some engine oils contain different. For example, ours, anti-wear super American eutectic lubricating oil, which can not burn engine oil, enhance power and reduce noise. I am the manufacturer can be contacted.

There is no such thing as a special oil for motor oil.
