Please ask the abnormal sound of the new Swift 1.4T engine compartment cold start

Speedeng 4t burning engine abnormal sound, which can be roughly divided into The engine makes abnormal noise during cold start, the engine makes abnormal noise during rapid acceleration, and the engine makes abnormal noise during idleness. Abnormal noise caused by aging or looseness of the machine foot mat.

If there is a strange sound of the belt and the belt whistling, it is generally caused by the slipping of the belt. If it is the sound of air leakage, it may be blocked, broken and other problems of the exhaust system and vacuum tube; if the external metal parts friction sound when the engine is running, it may generally be caused by damage to the generator, water pump, etc.

There is an abnormal sound after the speeding cold car starts, which is usually caused by the wear of engine parts. When the cold car starts, the internal lubricating oil film of the engine has not yet been formed, resulting in increased friction, resulting in abnormal noise. If this abnormal sound disappears in a short time, it can be regarded as a normal phenomenon and there is no need to worry too much.

Analysis of the reason why there is a strange sound when the speedy cold car starts: 1. It only disappears in a few minutes after the first start in the morning, that is, the valve is ringing. It should be that the oil has not reached the cylinder head in the oil pan shell, which is a normal phenomenon.

Volkswagen Swift has a strange sound when starting, and the new Swift has a strange sound when driving on a bad road

1. The abnormal sound during the bad road of the new speed may be the sound made by the engine. If it is a harsh sound of metal, or a strange sound like a wind whistle, it is caused by the wear or improper adjustment of some parts of the engine.

2. The failure of the exhaust system may also cause the abnormal noise of Volkswagen Swift. The abnormal noise problem of Volkswagen Swift may also be related to the exhaust system. The connectors or abnormal shock absorbers of the exhaust pipe may be loose or damaged, resulting in noise. In addition, abnormal back pressure of the engine may also cause abnormal noise.

3. For example, the "rattling" sound made by the dry friction of the bearing, the "tattling" sound similar to the small hammer hitting the cement floor when the valve gap is too large. When diagnosing abnormal car noise, attention should be paid to creating good auscultation conditions and trying to exclude the interference of other noises so as not to affect the accuracy of judgment.

What's wrong with the noise of the speed engine?

Speeding has a squeaky sound when driving at low speed, which may be because the brake pads are not worn flat and the position of the brake pads is out of the correct position, resulting in a squeaking sound when driving at low speed. Solution: Remove the brake pad and polish the edge of the brake pad with the angle grinder, so that there will be no hard friction and adjust the deviation position.

The most likely time is when the engine is hot, cold or lacks oil.The reasons for such problems can be divided into air filters, spark plugs, ignition lines, gasoline, gasoline filters, gasifiers, oil pumps and other problems.

Stepping on the accelerator, I found that the acceleration was not obvious, lacked power, and the engine had a hysterical sound. The most likely time to happen is when the engine is hot, or cold, or when there is a shortage of oil. The reasons for this kind of problem can be divided into air filter, spark plug, ignition line, gasoline, gasoline filter, gasifier, oil pump and other problems.

Car engine makes abnormal noise? Speeding

1. How to deal with abnormal noise of Speeding engine: If the engine makes an abnormal sound, it means that the engine valve carbon accumulates too frequently and the valve is blocked. Just clean the engine valve; if it squeaks, the engine belt will be loose.Adjust the engine belt. If the belt is not elastic, please replace the new belt so that there will be no abnormal noise.

2. Too much carbon in the engine; improper use of engine oil or dirty oil. In addition, most of the engine noise is caused by abnormal engine noise: the engine lower guard screw is loose. A relatively common small fault, tightening or adjusting the under-engine guard screw; the engine claw pad is aging.

3. There are two most fundamental reasons for the loud noise of the Swift engine: too much carbon in the engine. The engine oil is used inappropriately or the oil becomes dirty. In addition, most of the engine noise is caused by the abnormal noise of the engine: the screws under the engine are loose.

How to deal with the abnormal noise of the Swift engine

The causes and solutions for the abnormal noise of the Swift engine are as follows: the oil is insufficient, resulting in the inability to lubricate normally in various parts. The sound of wear and tear can be solved by adding oil; poor fuel combustion: too low fuel injection pressure, oil injector drip, poor oil injection atomization, and too late oil supply time will cause poor fuel combustion and cylinder knocking.

The engine belt makes an abnormal sound. Including power belts, generator belts, etc., the belt is aging or too loose or too tight will produce abnormal sounds, replace or adjust the tightness; the engine bursts. There is too much carbon inside the engine or the fuel use is not qualified. Clean the accumulated carbon and replace the fuel; the valve makes an abnormal sound.

The solution is as follows: if the car is not driving at low speed and the water temperature is normal, if there is a beep,It is the noise made by the electronic fan used in the cooling tank, and the cooling fan in the car is driven by a separate motor, which may be a failure of the temperature sensor or temperature regulator.

c. If there is too much carbon inside the engine, you can first try the carbon cleaning effect by disassembly-free cleaning or pulling at high speed, otherwise you can only clean the carbon by disassembling the engine. Generally, the more serious ones are often accompanied by the serious burning of engine oil. The valve makes an abnormal sound.

Solution: The abnormal sound of the engine indicates that the technical state of a mechanism of the engine has changed. It is mainly caused by the wear of some parts or even improper assembly adjustment. Some abnormal sounds can indicate that the engine may be accidentally damaged, so when the engine has abnormal noise, it should be repaired in time to prevent the failure from expanding.

What is the reason for the abnormal sound of the Volkswagen Swift engine

1. [Pacific Automobile Network] The abnormal sound of the engine indicates that the technical state of a certain mechanism of the engine has changed. It is mainly caused by excessive wear or improper assembly and adjustment of some parts. Some abnormal noises can predict that the engine may cause accidental damage. Therefore, when the engine has abnormal noise, it should be repaired in time to prevent the expansion of the fault.

2. The abnormal sound of the engine indicates that the technical state of an engine mechanism has changed. The main reason is that some parts are excessively worn or improperly adjusted, and some abnormal sounds can indicate accidental damage to the engine. Therefore, when the engine makes an abnormal sound, it should be repaired in time to prevent the failure from expanding.

3. The engine accumulates too much carbon;The engine oil is used improperly or the oil is dirty. In addition, most of the engine noise is caused by the abnormal sound of the engine: the lower guard plate screw of the engine is loose. A relatively common small fault, tightening or adjusting the under-engine guard screw; the engine claw pad is aging.
