Geely King Kong hot car idling shakes for a while, and all four cylinders are working?

The car problem, the repairs done are suitable! It is recommended to see if the pressure of the oil pump is enough, whether the oil circuit is smooth, and whether there is any blockage! In addition, whether the added gasoline has a high moisture content and whether the fuel tank is stained!

Geely King Kong hot car idling shakes for a while, and all four cylinders are working? The Civic is a good car and comfortable to drive, but no matter how good a person is, there are shortcomings, and no matter how good a car is, there are times when it is uncomfortable. At 8000 kilometers, the red light began to have a slight jitter a little more and more obvious, and finally can only be checked, there is no fault code and no problem, which is strange, I really don't want to endure the distress of this jitter, put more research in our car friends will someone to solve this phenomenon.

With curiosity and learning to invite this buddy to eat, I later learned that the reason, not that the car is not bad, but that our engine has a large compression ratio and high fuel requirements, which is also an environmental protection requirement, in fact, it is quite advanced. At least it meets the national environmental protection requirements and benefits future generations. He also gave all kinds of inspections without problems, a classmate of the oil testing company told him, it should be dirty oil circuits, new cars should not, the classmate told that gas stations are clean underground oil tanks, you do to ensure that your fuel tank oil circuit is not dirty?!!

So it feels right. The classmate gave him two Siyoupu fuel cleaners, and he said that he didn't feel it at first, but after 10 kilometers, he felt that the throttle was lighter and the noise was less. After a tank of fuel, the power feels strong at low speeds.

The jitter was reduced, and the car was completely smooth after 3 tanks of oil. That's what I did, and it was a perfect solution to the idle jitter problem in the end.

There are three reasons for the severe shaking and vibration of Geely King Kong engine, which are as follows: 1. The engine is seriously corrupt and carbon deposited. The common reason for the shaking and vibration of the car is that the throttle is too dirty and the nozzle has too much carbon.

If there is too much carbon inside the engine, the gasoline ejected from the cold-start injector will absorb a lot of carbon and the carbon deposits need to be removed immediately. 2. The engine lacks cylinders. Engine cylinder shortage mainly refers to the engine judgment of more than one cylinder is not working properly, which is manifested as obvious intermittent flow of automobile exhaust gas, while the exhaust pipe shakes violently, the engine shakes obviously, sometimes accompanied by a sudden sound, and it is necessary to check the ignition coil failure.

3. The combustible mixture of the engine becomes lighter or thicker. The lower the temperature, the more oil is required for cold start, and the carbon deposition affects the smooth or not of cold start. The front oxygen sensor needs to be replaced.

Engine vibration problems need to be checked and maintained immediately, check whether the ignition system, air intake system, and fuel system are faulty, and if there is a fault, troubleshooting should be carried out immediately.

Check the tire pressure first to see if the front and rear tire pressure is consistent. The balance of the original wheels is off or deformed, causing the car to swing under high-speed driving, and the steering wheel shakes rapidly from the rock state. The ball joint of the transverse thrust rod is loose or the bracket is loose and closed, resulting in unstable driving.

Carbon deposits can cause insufficient combustion of gasoline and cause the engine to shake. The impact of engine carbon deposition on the car is quite large, first of all, to reduce the engine power, that is, to make the power output uneven and gradually decay, in other words, more and more powerless. The second is to increase fuel consumption and increase your financial burden.

The third is the difficulty of cold start, that is, the difficulty of ignition, it is not easy to get on the car, and finally the carbon deposit in the combustion chamber is strict, and a heavy one will also cause cylinder detonation, and there will be a sound of low-speed acceleration, which will cause damage to the piston and crankshaft, and cause high temperature of the engine, which will seriously affect the safety of the car. Then there is the excessive discharge, which not only fails the annual inspection and inspection, but also directly aggravates the harm of polluting the environment.

There is another reason: the throttle valve is faulty. Both of these problems can cause engine shake and unstable speed.

Geely King Kong generation, the hot car idling is a little shaky, shake once in three or five seconds, sometimes shake once in half a minute, what is the problem, the spark plug has just been replaced! When the store is maintenance, it is directly added to the company with fuel additives in the fuel tank to clean the oil circuit, which should be able to clean the carbon deposits, and now 8w kilometers, the car has never been idle and shaken.

If you notice significant body shaking when starting or stopping the vehicle without turning off the engine, it may mean that the vehicle has one of the following three conditions:

1.The engine has a lot of carbon deposits.

The most common cause of car shake is a dirty throttle or excessive carbon build-up in the fuel injector. When the carbon deposition inside the engine is excessive, the gasoline sprayed by the cold start fuel injector will be absorbed by the carbon deposition in large quantities, 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 on the car, and the gasoline adsorbed on the carbon deposition after the car 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, causing 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.

Solution: Clean the oil circuit and check whether the idle motor has carbon deposits and should be cleaned.

2.Problems with the ignition system.

Check the working condition of the spark plug, high-voltage wire and ignition coil, the ignition system is not working well, and the spark plug tripping condition is not good, which will also lead to this kind of failure.

Solution: Check whether the spark plug has too much carbon deposit, and replace the spark plug.

3.The oil pressure is unstable.

If you have cleaned the engine carbon deposit, washed the throttle, changed the oil pad and spark plug, etc., and still found that the body shakes when idling, it is recommended that you go to the 4S shop to check whether the fuel 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, the body shake will be triggered.

Solution: Check the oil pressure and replace the parts if necessary.

4. Aging of engine parts.

Car jitter is also related to the aging of the engine feet (also known as claw pads). The engine foot is actually the suspension system of the engine, and the engine foot is responsible for absorbing the subtle shake of the engine when it is running, and if there is a problem with the engine foot, these vibrations will be transmitted to the steering wheel and cab, causing shaking when idling.

Workaround: Replace the parts.

As soon as it rains, Geely King Kong idles unsteadily when waiting for the traffic light, what is the reason for the serious shaking of the car? It has been determined that there is a lack of cylinders, coils, etc., the throttle has been so thinking about the problem, I have solved the problem of jitter, that is, PetroChina also cleaned the underground oil tank once in February, but the private car never cleaned the fuel tank, the problem is not coming, we add 95 98 can ensure that the impurities are not excessive every time, if the impurities are normal, why do gas stations have clean underground oil tanks,. In fact, it is caused by poor combustion, oil impurities, moisture impurities and gums.

Isn't it shaking? I also didn't have a fault in the end, after adding 2 Si Youpu, I ran 4 tanks of oil, the shaking was completely gone, it was smooth and quiet, and the fault code disappeared by itself, you can learn from it. It's really not a problem with the engine.
