minir56 1.6l engine noise

fault phenomenon: the user reports that the vehicle engine fault light is on. Fault analysis: (1). Troubleshooting analysis stepsCheck the engine control unit and find a fault code: "2B16---low credibility of the intake pipe differential pressure sensor"; When the engine is idling, observe the intake manifold pressure data, which is 87 kPa, which is normal.

The cause of the failure, the sound of the valve or the fuel injector, the carbon tank solenoid valve also has this sound, but the sound is relatively crisp. There is a way to distinguish it, that is, to give some oil at idle speed to see if the frequency has changed. If the frequency remains unchanged, it is the sound of the solenoid valve.

minicountryman engine noise is loud

1. Reason: engine oil Because the old engine oil is getting thinner and thinner, more and more carbon accumulates. When the oil is thin, it is easy to spee the oil, resulting in more and more carbon accumulation and loss of a lot of power.When replacing with new oil, the engine cannot adapt to the viscosity of the oil, which may increase the speed, resulting in loud engine noise.

2. You can go to the 4S store in time to check the internal structure of the car engine, and comprehensively overhaul the noise source of the car engine to solve the problem of car engine noise. MINI Countryman is MINI's first SUV model. The original family atmosphere of MINI is retained on the body line.

3. The reason why the BMW mini car engine is particularly noisy is that the timing system inside the BMW mini engine is the timing chain. The solution is: you can go to the BMW 4S store in time to check the internal structure of the car engine, and comprehensively overhaul the noise source of the car engine to solve the problem of car engine noise.

4. 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.

5. The reason why the engine still makes noise after the mini is turned off is: the cooling sound of the ternary catalyst; the cooling sound of the exhaust pipe; the abnormal sound of the water pump; and the sound of the cooling fan working. Mini's models include: minijcw, minicountryman, miniclubman, minicoupe, minipaceman, etc.

6. As for the others, it may be internal problems of the engine, such as EGR valve blockage. There is a hissing sound in the engine.Just like steam or air coming out of the engine, the engine will quickly lose power after hearing this sound. There may be a problem. The engine is overheated. Check the cooling system.

Benben MINI engine noise loud, how to repair

Poor oil quality. If you use poor-quality fuel, the combustion in the engine will deteriorate, resulting in violent vibration and noise in the engine.

Solution: In this case, replacing better quality fuel can generally reduce the engine noise; the engine is fixed and loose. You should know that the engine is not simply placed in the engine compartment, but is supported and fixed by parts such as claw pads. If those parts are aging and loose, it will lead to the start-up. The machine makes noise when it is working.

First, if the sound comes from the back of the car, then it should be a problem with the silencer.

It may be the jitter caused by insufficient combustion in the engine during operation, or it may be the jitter caused by the fracture shift of the fixed support of the engine or the rubber part of the bracket village sleeve.

Solution: Engine abnormal sound indicates that the technical status of a certain mechanism of the engine has changed. It is mainly caused by some parts being worn or improperly assembled and adjusted. Some abnormal noises can also foreshadow that the engine may cause accidental damage. Therefore, when the engine has abnormal noise, it should be repaired in time to prevent the failure from expanding.

Benben mini, like other mini cars, due to the low displacement of the engine used, the car has to step on the accelerator to increase the engine speed when lifting, so the noise is loud.

Why is the BMW mini engine particularly noisy

1. The abnormal sound of the BMW mini engine is mainly caused by the abnormal speed state, the excessive gap between the piston and the cylinder, or the wear of the contour of the gas distribution cam.The abnormal noise of the engine is most likely to be related to the speed status of the engine, and it may also be related to the load, which can be eliminated by gradually lifting the load.

2. The reason why the BMW mini car engine is particularly noisy is that the timing system inside the BMW mini engine is the timing chain. The solution is: you can go to the BMW 4S store in time to check the internal structure of the car engine, and comprehensively overhaul the noise source of the car engine to solve the problem of car engine noise.

3. This should be normal, because the hot parts of the engine and the exhaust pipe make a sound during the cooling process after parking. Heat expansion and cold contraction, the temperature of extinguishing and exhaust drops rapidly within a certain range, and the sound of small-scale deformation of the metal surface.

4. The BMW mini starter needs to be started with a battery. It clicks and can't be started because the battery is out of power. It can be started after being fully charged. It is difficult for ordinary car owners to distinguish which are faulty and which are reasonable. When I went to the repair shop to test the abnormal sound of the vehicles, only nearly 20% of the vehicles really had problems.

5. When accelerating, the engine makes a hissing sound, or when it slows down, it also appears. In short, it changes with RPM, and the volume changes. The possible reason is that the power steering oil is missing, fill it up. The generator bearing may be damaged. Problems with power steering pumps and water pumps will produce similar noises.
