Why does the car body shake when the car air conditioner is turned on?

The reasons why the air-conditioned car will shake are: 1. The compressor pressure is too high; 2. The throttle needs to be cleaned; 3. Carbon deposition or aging of the engine; 4. The problem of air conditioning. The way to deal with the shaking of an air-conditioned car is:

1. Check the high and low pressure of the air conditioner to see if the pressure of the air conditioner is too high; 2. Clean the throttle; 3. Clean up the carbon deposits of the engine; 4. Check whether the radiator of the air conditioner is unobstructed. An automotive air conditioner consists of a compressor, a condenser, an expansion valve, and an evaporator. Automobile air conditioner is the abbreviation of automobile air conditioning device, which is used to adjust and control the temperature, humidity, air cleanliness and air flow in the car cabin in a better state.

The reason for the body shaking when the car is turned on is that the spark plug and the engine intake valve have carbon deposits, and the role of the automobile air conditioner is: 1. The continuous change cycle of refrigerant is used to achieve the refrigeration effect; 2. The engine coolant, waste heat or burner are used to generate heat, which is heated by the heater as the heat source for heating, and sent into the air inside or outside the car by the blower, so that the temperature of the air outlet rises to achieve the purpose of heating; 3. Sucking fresh air from the outside into the car can ventilate and ventilate, which also plays a good role in preventing fogging of the windshield; 4. Remove the dust, odor, smoke and toxic gases in the air in the car, make the air in the car fresh, humidify the air in the car, and improve the relative humidity of the air in the car.

Because when the air conditioner is turned on, the engine is just starting, so the car is shaking.

Because of car compressors. worked. Motor. It's hard, so there is shaking.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

Caused by insufficient vehicle power, engine failure, or spark plug failure.

After the compressor of the air conditioner is started, the pressure is too high, which causes the vehicle to vibrate, and the engine of the vehicle needs to be repaired or replaced in time.

The carbon deposition of the engine valve is serious, which makes it difficult to start the vehicle, and the load on the engine will increase, resulting in jitter, and the owner needs to clean the throttle valve in time.

If the spark plug inside the engine is damaged, the spark plug will be damaged by carbon deposit, or the spark plug will be poorly flashed, which will affect the normal operation of the engine, and the owner needs to clean or replace the spark plug in time.

The fan blades of the air conditioner fan are deformed, so when the air conditioner is working, the fan and the engine will resonate, and the owner needs to replace the damaged fan in time, so that the vehicle will not shake.

After the vehicle is turned on the air conditioner, the load on the engine will increase, and if the vehicle is faulty, it may lead to unstable idle speed and high and low speed after the air conditioner is turned on. The most common reasons are as follows:

1. It may be caused by too much carbon deposition inside the engine of the vehicle, resulting in idle shaking after turning on the air conditioner.

2. There is a problem with the ignition system of the vehicle, and it is necessary to check the spark plug and high-voltage wire of the vehicle.

Precautions for turning on the air conditioner in the car.

It is necessary to pay attention to the time to turn on the air conditioner, and the long-term opening of the air conditioner will increase the burden on the condenser, which will not only affect the refrigeration effect of the car, but also cause some damage to the engine, so you can turn it off for a while after a while.

Some car owners like to turn on the air conditioner when the vehicle is not started, so that although people are comfortable, the power used by the air conditioner at this time is in the car battery, which will lead to a serious feeding phenomenon in the battery.

The oil pressure is unstable.

If you still find that the body is shaking, it is recommended to go to the maintenance shop to check whether the fuel supply pressure and intake pressure sensor are normal, if the oil pump oil supply pressure is not normal, the intake pressure sensor value error and improper work will cause the body to shake.

The main reason for cold start cold start body shaking is insufficient fuel combustion, resulting in insufficient power of the car. The ignition energy is low, and when starting, when the temperature of the fuel and lubricating oil is low, we need to rely on more fuel to meet the power. After a long time, the pole gap of the spark plug will gradually increase, resulting in a decrease in ignition energy and poor fuel atomization, resulting in body shaking.

In winter, the fuel consumption of the car is increased when the air conditioner is turned on? Many car owners don't understand, it must be a fault here!

There may be two reasons for the shaking of the air conditioner: 1. The vehicle will produce carbon deposits in many places with the increase of mileage, especially the throttle. If the throttle is dirty, it can block the air intake, resulting in an engine that is not strong or barely able to drive the compressor.

Therefore, there was a situation where the air-conditioned car was shaking. 2. When the engine is working normally, there will be vibration, but part of it will be filtered out through the engine mount, so we don't feel obvious. If the engine mount collapses or breaks.

Good afternoon, when the air conditioner is turned on, it is not normal for the body to shake. The general cause of this is a dirty throttle. Or the air conditioner compressor is damaged, the dynamic balance of the air conditioner fan is not good, and the throttle needs to be checked and cleaned. Replace damaged parts.

The shaking of the air conditioner in the car is generally caused by carbon deposition in the spark plug, carbon deposition in the throttle valve, or deformation of the fan or falling off the screw. After turning on the air conditioner, the engine load increases suddenly, the throttle opening expands, and the shortcomings of dirt are magnified at this time, and the throttle opening is stuck or fails to open to the appropriate position, resulting in the obstruction of the air intake, which will reduce the power of the engine, and finally evolve into engine shaking.

Here is a detailed description of the reasons why the car turns on the air conditioner and shakes:

1. Spark plug carbon deposits:

After a period of use, the spark plug will have carbon deposits, and if it is not cleaned in time, the engine output torque will be reduced. When the air conditioner is turned on, it will shake. Put the spark plug into a container filled with white vinegar and soak for 2-3 hours, and soak for 4-5 hours for serious soaking, then find a hard brush, and the carbon deposits will fall off after brushing a few times.

Then clean it with gasoline and let it air dry for a while.

2. The fan is deformed or the screw is falling off

Check whether it is due to a resonance that occurs when the fan is deformed and running after the air conditioner is turned on, or whether the fixing screw of the fan falls off and causes vibration.

When the car turns on the air conditioner and shakes, check whether the throttle valve is clean, and then see if it is a problem of missing cylinders.

Hello, because the load on the air conditioning engine is large, it is recommended to clean the lower throttle valve and see if the spark plug needs to be replaced.

Hello: After the air conditioner is turned on, the load on the engine increases, so it will shake, and the idle speed of the engine will also increase, which is a normal reaction.

There are many reasons to see if the air conditioner does not speed up, which leads to jitter, and then cleans the carbon deposit.

Hello! The throttle is dirty, clean the throttle and idle valve!

A: The engine is overloaded.

Reason analysis: 1. The air conditioner is driven by the engine.

2. When the engine load increases when the air conditioner is turned on, the engine speed will decrease or shake, and this phenomenon will disappear automatically with the adjustment of the engine fuel injection volume. Otherwise, it is a failure.

Inspection parts: 1. Check the high and low pressure of the air conditioner, when the pressure is too high, it will cause the engine load to increase sharply;

2. Check the suction of the electromagnetic clutch of the air conditioner;

3. Check whether the radiator of the air conditioner is dirty and blocked;

4. Check whether the condensate is too much;

You go to the place where the car is repaired to check whether the air conditioner is out of order or broken, and I feel that this is the case with you. Generally, after the car air conditioner is turned on, the engine speed will be increased by about 300 rpm, if the speed-up device fails or is broken, it is equivalent to your idle speed is reduced, then your car must be obviously trembling.

The power of the car is insufficient, and the power required to turn on the air conditioner is not small, which is easy to cause similar consequences of towing operation, and check and clean the problems of carbon deposits in the oil circuit.

There will be a slight jitter when the compressor is working! If there is a slight shaking, don't worry about it, if it's particularly obvious, there is a problem, clean the throttle and try!

In winter, the fuel consumption of the car is increased when the air conditioner is turned on? Many car owners don't understand, it must be a fault here!

Pacific Automobile Network] When you drive an air-conditioned car, it will shake because the throttle is dirty, which affects the engine. If the air conditioner is turned on again at this time, the engine will be idling aggravated, and the car will shake. Therefore, this can be avoided by cleaning the throttle or cleaning up the engine carbon deposits.

As soon as the car turns on the air conditioner, there are several reasons why it can be checked:

1. The compressor pressure is too high.

If the air conditioner is turned on, there will be idle shaking, it is likely that the shed is because of the problem of high and low pressure, so be sure to check the high and low pressure of the air conditioner to see if the pressure of the air conditioner is too high, because the pressure is too high, the engine load will increase, which will affect the stability of the car.

2. The throttle needs to be cleaned;

If you start the car and turn on the air conditioner, there will be idle shaking, so be sure to check whether the throttle is clean, and clean it in time if it is not clean.

3. Carbon deposition or aging of the engine;

If the engine is not cleaned or aged because of the long chain first balance time, it will affect the normal operation of the engine.

4. The problem of air conditioning.

Check whether the radiator of the air conditioner is unobstructed, which will also affect the phenomenon of idle shaking when the car is turned on the air conditioner.

When the car turns on the air conditioner, it shakes this is the vehicle's throttle is dirty, under normal conditions, turn on the air conditioner, the throttle will increase the opening, to compensate for the additional energy consumption, if the throttle is dirty, it will cause the air intake to be small, the engine can not bear the load will shake, clean the throttle, the specific operation steps are as follows:

1. Remove the throttle hose.

2. Open the throttle flap.

3. Use a brush to clean.

4. Spray with cleaning agent.

5. Replace the hose and it is completed.

Precautions: 1. Do not get the dirt of the throttle inside.

2. Use a special throttle cleaner, otherwise the internal rubber ring will be damaged.

In winter, the fuel consumption of the car is increased when the air conditioner is turned on? Many car owners don't understand, it must be a fault here!

The power of the automobile air conditioning compressor generally comes from the accessory belt driven by the crankshaft, when the AC of the air conditioner is turned on, the switch of the compressor is turned on, the electromagnetic clutch is combined, and the compressor power is turned on, at this time, it will affect the balance of the crankshaft rotation, and at this moment, the engine will shake.

Causes of body shake when the car air conditioner is turned on:

1. The throttle is dirty, the engine will shake slightly, but it is not easy to notice, once the air conditioner is turned on, the load of the starting beam will increase, and the shaking will be aggravated; This is the most common situation, just wash the throttle. At the same time, check whether the condenser is dirty and blocked, and whether there is any problem with the ignition system.

2. The power of the vehicle is too small, and because of the automatic transmission, the power is not enough at high speed, coupled with a high-power air conditioning system, there are some suspicions of "small horse-drawn carts", so the steering wheel shake is intensified.

3. The air-conditioning compressor is damaged, which is the most serious reason for Sun, because once damaged, it is basically impossible to repair it, and it can only be replaced.

This is the case for old cars that are more than 6 years old, while new cars are basically not present. Along with the shaking, there is also a problem that the air conditioner does not produce cold air, but the blower keeps ringing. If both of these phenomena occur, then 90 could be a problem with the compressor.

When the car's air conditioner is turned on, the body shuddering can be caused by a number of reasons. The most common cause can be the failure of the air conditioning system, such as the failure of some components or the lack of refrigerant in the air conditioning system.

In addition, the refrigeration system of automobile air conditioner needs to compress the refrigerant into high-pressure gas through the compressor, and then reduce the pressure through the pressure reducing valve and other components, and cool it down to produce cold air in the evaporator, which requires relatively high mechanical energy support. When the air conditioner is turned on, the engine is unstable, which may cause the body to tremble and shake. In addition, in hot weather, driving for longer periods of time can lead to higher temperatures in the engine, transmission system and chassis.

When you turn on the air conditioner, the air conditioning system will suck air from these hot surfaces and drain it through the evaporator. This draws some heat, which causes the car to shake slightly.

To solve this problem, we need to perform a series of inspections and maintenance. First of all, check the air conditioner and make sure there are no faults. If you find that there is still body shaking, you can also check for damage or wear and tear on car accessories, such as the drivetrain or suspension.

In addition, the wheels and tires need to be checked for balance, which can also cause the body to tremble. In future use, it is necessary to ensure that the air conditioning system is regularly maintained and follow the manufacturer's regulations so that the air conditioning system remains in optimal condition. With regular vehicle inspection and maintenance, you can be sure that your car will not shake and shudder when the air conditioner is turned on, ensuring comfort and safety throughout the driving process.
