What s going on with the Bora engine, what s going on with the new Bora engine

1. The causes of hysterical sound problems in the engine can be divided into air filter, spark plug, ignition wire, gasoline, gasoline filter, vaporizer, oil pump and other problems. Check the air filter, whether it is dirty, whether the spark plug is old and has to be replaced, the ignition coil is broken, the gasoline is not clean, such as water in the oil circuit. There are also inspections of oil pumps, vaporizers, etc.

2. When driving, the acceleration is normal, and the ignition may be normal, but if you drive at a constant speed, you find that the engine speed is too high, but the speed still can't be raised. Try checking the coolant, if the oil pressure is too high, or too low, check the oil pressure gauge, and there may be a problem with the ignition time setting, which can also cause these symptoms. As for the rest, it could be an internal engine issue, such as EGR

clogged valves, etc.

3. The engine has a sizzling sound, there may be a problem, the engine is overheating, check the cooling system. The exhaust system is clogged, the vacuum tube is leaking, or it is broken.

4. When accelerating, the engine will have a whirring sound, or when decelerating, it will also appear, in short, with the rpm change, the sound volume changes. The possible reason is that the power steering oil is missing, and the fuel is filled. Generator bearings may be damaged.

Power steering pumps, water pumps, will produce similar noise.

The stability of the Bora model is okay, basically there is no abnormal engine noise, and it is necessary to check whether it is caused by resonance.

There will be a knocking sound when refueling, especially when going uphill, especially when going uphill, and the tachometer is also noticeable above 1500 rpm! I went to 2 4S stores to inspect before, but I didn't give a plan and couldn't solve it. It is also obvious that the engine burns oil!

I hope that the manufacturer can make technical improvements to solve these problems! This problem defect has been broken out on the car quality network, and if there is the same problem, the owner can also give feedback.

If your car's engine has abnormal noise, it is best to let the maintenance technician actually test it or test it together. If the air conditioning effect is not good, it should not feel very cool, you can simply see whether the refrigerant is sufficient from the observation window of the air conditioning pipeline, and whether there is catkins or dirty things outside the water tank that cause the system to dissipate heat poorly.

Bora's new engine abnormal noise, this must be a hardware problem, you must go to the car purchase documents and 4S negotiation, if it is a big problem, directly let him give you a new one, this is outrageous. Be sure to be careful when driving lately.

This suggestion went to the 4S store to check it, and the specific cause of the failure was generated.

The abnormal engine noise indicates that the technical state of a certain mechanism of the engine has changed. It is mainly caused by excessive wear and tear of some parts or improper assembly and adjustment. Some abnormal noises can still predict that the engine will be damaged accidentally, so when the engine has abnormal noise, it should be repaired in time to prevent the fault from expanding.

It should be reminded that if it is an abnormal noise in the engine.

1. Abnormal engine noise Symptom description: There will be more abnormal noise in the engine compartment, and most people also judge that it is the abnormal noise of the engine compartment based on the sound, which is usually a metal screech or wind howling noise. Workaround:

It is mainly caused by excessive wear and tear of some parts or improper assembly and adjustment. Some abnormal noises can still predict that the engine will be damaged accidentally, so when the engine has abnormal noise, it should be repaired in time to prevent the fault from expanding.

It should be reminded that if it is an abnormal noise in the engine, most of the owners will not be able to solve it by themselves, and it is best to send it to the factory for maintenance.

2. There is no abnormal sound in the gearbox Symptom description: If there is a "rustling" sound inside the gearbox during driving, and there is no more after stepping on the clutch or accelerator, there will be a sound similar to whistling when changing gears. Workaround:

There are many transmission parts, and the reasons for the sound are also more complex, so it should be noted in the analysis and judgment: whether it is related to a specific speed, such as some planetary teeth that sound at about 50km h are more obvious. Whether it is related to certain gears, which is very important for judging the failure of the transmission, if a certain gear sounds, it must be related to the components that affect the transmission of the gear; If all gears sound, it is often a common meshing shaft failure or a lack of oil in the transmission.

Whether it is related to specific actions, such as increasing and decreasing gears, starting, rapid acceleration, sharp deceleration, turning, etc., are effective means to judge abnormal noise, among them, changing speed and direction are particularly important for judging the rear axle fault. If the abnormal noise of the transmission is obvious, it is recommended to send it to a professional repair shop to check the faulty parts, and then replace them.

3. There is an abnormal sound in the door Symptom description: When driving on the accelerator or brake, there is always some abnormal noise in a certain part of the body, the sound is not loud, and it does not affect normal driving, but it always makes people worry that there is a malfunction. Workaround:

The abnormal noise of the door is mainly caused by the lack of lubrication, but it is necessary to determine whether it is the position of the door hinge or the glass regulator, door lock mechanism, handle mechanism, etc. inside the door. In the case of door hinges or limiters, special door hinges and slideway grease can be used, while special door bumper grease is used for lubrication of glass regulators, door lock mechanisms, handle mechanisms, etc. inside the door. In terms of brand selection, try to choose the commonly used brands in 4S stores, such as Kruber, Hotolube, Fox, etc.

It is not advisable to use engine oil or ordinary butter, it will freeze in winter, and the harmful smell will affect your health.

1. It may be a carbon deposition phenomenon, when there is too much carbon deposition in the engine wheel, the ignition energy of the car will be greatly reduced, and the air intake efficiency will continue to decline, and the engine power will decrease, and then the acceleration will be weak.

2. It may also be that there is a problem with the fuel system of the car.

3. This will also happen when the driver fills up the fuel that does not match.

4. When the vent of the automobile fuel tank cover is blocked, the fuel tank switch, fuel filter or state oil pipe is plugged, there will be insufficient oil volume, and if the engine mixture is too thin, the engine will accelerate weakly.

5. It may also be that there is a problem with the car intake system, the air is also the power of the car, after the air filter is used for a long time, if it is not cleaned in time, there will be a blockage of the wax dough stove, and when the air volume is insufficient, the mixture will be too thick, and the engine power will also decrease.

A summary of the new Bora squeak situation.

The new Bora exhaust pipe is abnormal.

Condition: During the driving process of the new Bora, there was a "sudden" sound from the exhaust pipe.

Solution: If there is a prominent "sudden" sound on the exhaust pipe in the case of the operation of the steam engine, it is mainly caused by the unstable operation of the automobile engine, and the ignition of the mixed gas is abnormal.

New Bora manual reverse squeak.

Condition: When the new Bora manual gear is in gear, there is a "click" sound in the process of reversing.

Solution: Under normal circumstances, the manual transmission of the vehicle in the reverse gear driving, especially the reverse gear to speed up the link will form a significant running sound, there is a sound similar to "angang", for why there is such a abnormal sound when hanging the front gear, mainly because of the structural characteristics of the reverse gear itself, because the reverse gear is missing the spur teeth, and the forward gear is helical gear, you can test other manual transmission vehicles to carry out comparison and certification of the running sound of the reverse gear. However, if the steering noise of your car is very loud, it is also possible that there is abnormal damage to the gears or rolling bearings, and the abnormal noise can be eliminated by dismantling and replacement.

Millions of car purchase subsidies.

New Bora manual reverse squeak.

Condition: When the new Bora manual gear is in gear, there is a "click" sound in the process of reversing.

Solution: Under normal circumstances, the vehicle of Chaheng manual transmission will form a significant running sound in the link of hanging reverse gear driving, especially in the reverse gear to speed up driving, there is a sound similar to "Angang", for why there is no such abnormal sound when hanging forward gear, mainly because of the structural characteristics of the reverse gear itself, because the reverse gear is a straight gear, and the forward gear is a helical gear, you can test other manual transmission vehicles to compare and certify the running sound of the reverse gear. However, if the steering noise of your car is very loud, then it is possible that the gear or rolling bearing is abnormally damaged, and the abnormal noise can be eliminated by dismantling and replacing it.
