What s going on with jitter? What s the deal with accelerated jitter?

Body shaking is called tremor, which is involuntary movement and is manifested as a particularly rapid back-and-forth movement, mainly due to the alternation of active movement muscles and antagonistic muscles, or involuntary antagonistic contractions.

There are many reasons for body shaking, and the common causes are as follows:

1. Physiological phenomena: If you have a cold, it usually manifests as involuntary shaking of the jaw when you are cold. In addition, when panic, anger, emotional tension, and anxiety, it is easy to have hand tremors;

2. Pathological phenomenaTremor may also occur when hyperthyroidism, Wilson's disease, liver function, and renal function are abnormal. In addition, some patients have familial hereditary diseases, such as essential tremor, which are usually caused by parents and children are also prone to it, and usually have a long medical history, but it does not affect the patient's life.

Some cerebellar diseases or extrapyramidal diseases, such as tremor caused by Parkinson's disease, may also cause body tremors.

The common causes of trembling are as follows, the first is physiological tremor, anyone may have a little tremor when they are nervous, the tremor is not too large, and it will not exist for a long time.

The second is essential tremor, which is more common in young people, and there is often a family history of essential tremor, and 50% of patients can find a family history, such as siblings, parents, grandparents, etc. Essential tremor is characterized by tremors of the hands, followed by tremors of the head and feet. Hand tremor is postural tremor that is more pronounced when performing movements or holding positions.

The third is Parkinson's disease, which is mainly seen in middle-aged and elderly people, and is relatively rare in young people.

The causes of body shaking include physiological aspects, pathological aspects, etc., such as excessive nervousness, hypoglycemia, Parkinson's disease, etc.

1.Physiological aspects. When a person is too nervous, it causes sympathetic nervous excitement, causing muscles to tremble and body shaking. Or in a cold environment, the muscles will shiver, and the body will tremble.

2.Pathology: If there is hypoglycemia, Parkinson's or fever, the body may tremble.

Under normal circumstances, the engine shake should be smooth and regular, and if you can clearly feel the recent increase in the engine shake, then it is time to check. The following are the causes of two types of automobile engine shake failures. 1. The engine shakes more than normal when driving, and sometimes there is a problem that it cannot be started once.

It could be that the throttle is too dirty

Main causes of idle jitter:

1.Serious engine carbon deposits: Cars always have the problem of carbon deposits, including cylinder carbon deposits, throttle carbon deposits, spark plug carbon deposits, intake carbon deposits, etc.

When the engine has too much carbon deposit, it will affect the ignition energy, air intake efficiency and air-fuel ratio of the car, resulting in the unstable power output of the car, and the phenomenon of idle speed and acceleration jitter appears.

2.Unstable oil pressure: If you have cleaned the engine carbon deposits, cleaned the throttle, replaced the oil gasket and spark plug, etc.

And when idling, you still find that the body shakes, it is recommended that you go to the 4S shop to check whether the oil supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is abnormal, or the intake pressure sensor value is wrong, and the work is not good, it will cause the body to shake.

3.Engine cylinder shortage: Engine cylinder deficiency mainly refers to the engine one or more cylinders are not working properly, which is generally manifested as:

The exhaust gas flowing out of the car is obviously intermittent, and the exhaust pipe shakes violently, and the engine shakes clearly, sometimes accompanied by abnormal noises. This is mostly related to ignition coil failure.

4.Aging of engine parts: Shake in the car is also associated with the aging of the engine feet (also known as claw pads).

The engine foot is actually the shock absorber system of the engine. The engine feet are responsible for absorbing slight vibrations when the engine is running. If there is a problem with the engine base, these vibrations can be transmitted to the steering wheel and cab, causing vibrations at idle.

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.

Causes of the car's rapid acceleration and shaking:

1. The rapid acceleration and shaking of the car may be a fuel system failure. Generally, when the car accelerates, when the clutch is stepped on and the gear shift, it will be found that the speed drops sharply, and it will be accompanied by the phenomenon of shaking and staking, especially the performance of manual transmission models is more obvious;

2. Automobile acceleration jitter may also be: the general fault of the half-shaft fault is as follows: when driving to a certain speed range and then accelerating, the front of the car will have a regular jump, and the shake will disappear or reduce after loosening the oil;

3. Fault place: most of the inner cage in the half shaft is overworn, and a certain angle is formed between the gearbox and the half shaft due to the change of the force point, which leads to the feeling of the vehicle jumping. Most of the reasons for excessive wear of the inner cage are due to the fact that the dust jacket on the half-shaft shaft is broken, and the owner does not replace it in time; Therefore, if the dust jacket is broken and leaking, it must be replaced in time, and do not lose a big one because of a small one;

4. In addition, insufficient fuel injection and insufficient oil pressure in the oil circuit will also cause the automobile engine to shake during acceleration. Insufficient fuel injection is mainly due to the failure of the fuel injector, which may be too much carbon deposition or mechanical failure, which needs to be detected one by one. Most of the problems are due to the problem of oil pump and gasoline filter, and some car owners ignore the replacement of gasoline filter, which can easily lead to acceleration shake.

Causes of accelerated jitter:

1. The main reason for the failure is the increase in carbon deposits in the throttle, intake tract, valve and other parts, and when the car is cool, it will suck up some gasoline and stare at it, and wait until the hot car is blindly touched, and these gasoline will volatilize, which will cause the mixture to be too thick when the engine is idling, which will lead to the unstable idle speed of the hot car;

2. Therefore, it is necessary not only to check the throttle and idle motor, but also to check whether the carbon deposit and dirt in the intake tract are too much, if there are more, it will cause the cross-sectional area of the air passage to change, so that the control unit can not accurately control the amount of idle air intake, resulting in too thick or too thin mixture, so that the combustion is abnormal and causes the engine to shake. At the same time, it is also necessary to pay attention to check whether the carbon canister is faulty;

3. The most common fault of jitter during acceleration is that the spark plug is damaged, the spark plug is extremely positive and the point gap is worn to cause insufficient ignition of the spark plug, the mixture is not fully burned and the acceleration is shaking, and there is a crack in the ceramic part of the spark plug, which causes the spark plug not to ignite, and a cylinder that does not work will also lead to acceleration jitter.

Analysis of the causes of car shake:

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. Therefore, when the electrical system is turned on, especially when the orange is rotten, 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 and the throttle will not close tightly or the idle motor will be stuck, resulting in the engine idle speed is too high, and the carbon deposits generated by the engine in the process will also cause the vehicle to shake, especially when starting the car, 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 Yuanwei 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.

The reason for the acceleration shake is the increase in carbon deposits in the throttle, intake tract, and valve parts, resulting in an over-concentrated mixture when the engine is idling, resulting in unstable idling. Acceleration jitter solution: 1. The engine and idle motor have serious carbon deposits, and the oil circuit is cleaned; 2. Check whether the spark plug has too much carbon deposit, and replace the spark plug if it hits the ignition system; 3. Check the oil pressure if the oil pressure is unstable, and replace the parts accordingly; 4. Aging of engine parts, replacement of some aging parts.

The function of the engine: 1. The fuel fed into the cylinder is fully burned and the power is generated; 2. Determine the dynamics, economy, stability and environmental protection of the vehicle.

The cause of body trembling may be physiological factors, such as agitation, cold, etc.; It can also be caused by certain medical conditions, such as calcium deficiency, essential tremor, Parkinson's disease, epilepsy, etc.

1.Physiological factors: Normal people may shiver in the body cavity under certain circumstances, such as cold, overwork, fatigue, excessive emotion, crying, sadness, these reasons may cause the body to shiver, which will generally relieve itself.

2.Calcium deficiency: It can lead to decreased neuromuscular stability, involuntary muscle spasms, and body trembling.

3.Essential tremor: may manifest as involuntary shaking of the limbs, mainly in the head.

4.Parkinson's disease: Patients will also experience body tremors, mainly in the hands, jaw, and head.

5.Epilepsy: Seizures can manifest as involuntary twitching of the limbs, similar to body trembling.

If there are no physiological reasons such as agitation, cold, fatigue, etc., and the body suddenly trembles, you need to go to the hospital as soon as possible, clarify**, and standardize ** under the guidance of the doctor**.

Tremor is an involuntary tremor or shaking of the muscles or body. Tremors can occur for a variety of reasons, including:

Neurological problems: Certain neurological disorders or nerve damages, such as Parkinson's disease, multiple sclerosis, stroke, tremors, etc., may cause tremors.

Medications***: Certain medications, such as antipsychotics, antidepressants, piperazines, etc., may cause tremors as ***.

Anemia: Anemia (iron deficiency anemia, etc.) leads to a lack of oxygen**, which may cause tremors in the muscles and spine.

Anxiety and nervousness: Emotional tension, anxiety, and stress can also cause muscles to shake.

Hypoglycemia: Hypoglycemia (caused by diabetes or insulin excess) may cause tremors.

Thyroid problems: Hyperthyroidism or hypofunction can cause tremors.

If tremors persist or severely affect daily life, it is advisable to consult a doctor for evaluation and diagnosis. Your doctor may take a detailed history, physical examination, and laboratory or imaging tests as necessary to determine the specific cause of the tremor and develop a protocol accordingly. Targeting the primary**, medication, physical**, or other** may help control travel or reduce tremor symptoms. Thank you.

1.Physiological factors: such as involuntary tremor of the head, involuntary tremor when holding something or doing fine movements;

2.Genetic factors: called essential or essential tremor, the course of the patient's disease will not develop greatly, is determined by genetic factors, the age of onset is different, such as patients may be in their teens to more than 50s before they begin to appear, generally do relevant examinations will not have problems, and this kind of shaking will only appear when nervous or fine movements, most of them do not need **.

3.Pathological factors: Some diseases can cause general shaking, such as hyperthyroidism, systemic diseases, including Wilson's disease, and genetic diseases.
