What is the problem with Honda Sidi turning on the air conditioner and shaking from time to time?

According to your situation, most of the problem is the compressor, according to my experience in repairing air conditioners, it may be that your compressor flywheel belt is too loose or the suction cup is not working, you first look at the flywheel belt connected to the compressor, to see if the flywheel belt of the compressor is too loose, if you determine that the flywheel belt is connected normally, it can drive the compressor flywheel to rotate, if not, you will check the compressor; You first turn on the air conditioner switch, to observe whether the suction cup of the compressor can be sucked, if not, then check the compressor power supply, if the compressor is not energized, the suction cup will not work, if there is power supply, the suction cup will work automatically sucked back. If you can't tell the difference, you just need to touch the two pipes connected to the compression outlets, the high-pressure pipes are very hot, you must be careful, the low-pressure pipes are cold, and the refrigerant (fluorine) that has been separated after the shrinkage machine has been refrigerated, there is such a performance that shows that the compressor is in good condition, if these are good, you don't understand, it's best to go to the 4S shop to find the master to check the refrigeration system for you.

The idle speed you said is larger than usual, it should be that the compressor belt is oversent, or the slippage cannot drive the compressor flywheel to work normally, and the compressor does not work, so it will naturally not be refrigerated.

The reason is that the throttle valve is dirty, which affects the engine. After the air conditioner works, the compressor will also work, and the compressor is driven by the engine, so the compressor will increase the load of the engine, and increasing the load means increasing the throttle opening and increasing the air intake. If the air conditioner is turned on again at this time, the engine will be idling more aggravated, and the steering wheel will shake.

Therefore, this can be avoided by simply cleaning the throttle.

The main causes of engine shake;

1. The most common cause of engine shake is that the throttle valve is too dirty or the fuel injector has too much carbon.

2. When the carbon deposition inside the engine is too much, the gasoline sprayed by the cold start fuel injector will be absorbed by a large amount of carbon deposition, resulting in the mixture of cold start being too thin, making it difficult to start, in this case, only when the gasoline absorbed by carbon deposition is saturated, it is easy to get started, 3. After the car is adsorbed, the gasoline adsorbed on the carbon deposition will be sucked into the cylinder by the vacuum suction of the engine for combustion, and the mixture becomes thick, and the combustible mixture of the engine is dilute and thick, resulting in idle shaking after cold start. The lower the temperature, the greater the amount of oil required for the cold start, and the more carbon deposits will affect the smooth cold start.

Severe idle vibration is generally caused by engine cylinder failure, aging or loose foot rubber, carbon deposits, fuel system failure, etc.

Solution; The best way is to clean the oil circuit, clean it regularly, and use PNF fuel additives to solve the above problems caused by carbon deposits. The fuel quality is not very good or the initial fuel of the new car is stored for too long, resulting in a rapid increase in the colloidal composition of the oil circuit, which will continue to pollute the fresh fuel and cause no good fuel to participate in combustion in the later stage, and the carbon deposition exceeds the standard, which is especially common for China VI vehicles. We can only gradually alleviate most of the problems by maintaining clean oil circuits.

Analysis of the causes of the shaking of the gasoline version of the car:

1. Suspension system problems.

Body shake is also related to the aging of the suspension system. It is mainly responsible for filtering out the shake of the engine when it is running, and if there is a problem with the suspension, these vibrations will be transmitted directly to the steering wheel and cab, affecting the driving. When the engine is idling, it is easy to cause shaking when the electrical system in the car is turned on.

The engine will increase the load when the electrical appliances are turned on, causing the idle speed to drop, and to compensate for the jitter caused by the idle slip, the engine will automatically increase the speed by partially. So, when the electrical system, especially the air conditioner, is turned on, the engine will often shake. This jitter is likely to be caused by the aging of the shock absorber and needs to be replaced in time.

2. Tire problems.

For tires, the tire must be balanced once when the car is replaced with new tires and new steel rims, otherwise the steering wheel will be prone to shake when the counterweight is uneven. If you find that the tire weight is not equal, you need to add lead to the inside of the rim to average the weight of the tires on both sides. Whether it is a general steel ring or a lightweight aluminum ring, it may deform or crack when subjected to a certain external force.

Deformation of the rim can cause shaking when driving, uneven weight of the rim can also cause shaking when driving, and incorrect angle of the rim can also cause shaking when driving.

3. Throttle problems.

The most common cause of car shake may be a dirty throttle valve and excessive carbon build-up in the fuel injector. After the car travels for a period of kilometers, the throttle valve will be too dirty to cause the throttle to close loosely or the idle motor to stagnate, resulting in the engine idling speed is too high, and the carbon deposits generated by the engine in this process will also cause the vehicle to shake, especially when starting the vehicle, the engine will shake more than normal, and even sometimes there will be a phenomenon that can not be started at one time. Therefore, when the body shakes, the first thing to do is to check the throttle and fuel injectors.

If you find that the throttle valve is too dirty or the fuel injector has too much carbon deposit, you should clean it with fuel injector cleaner or throttle cleaner in time.

4. The oil pressure is unstable.

If you still find that the body shakes after these are finished, it is recommended that you go to the repair shop to check whether the fuel supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is not normal, the intake pressure sensor is wrong and improper work will cause the body to shake.

Oil pressure problems: whether the fuel supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is abnormal or the intake pressure sensor is wrong and the work is not good, it will cause the body to shake.

The most common time for engine idle shake is when the electrical system is turned on, if you step on the brake to hang D gear, turn on the air conditioner (AC compressor switch to turn on), turn on the headlights, the engine begins to shake, and the speed does not drop because of the load of the compressor, which can be determined to be the problem of aging of the engine's "foot glue", and the problem of shaking can be solved by replacing the foot glue.
