The Besturn B50 shakes very badly when idling, and is powerless when accelerating, and the spark plu

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. And one more reason:

The throttle valve is faulty. Both of these problems can cause engine shake and unstable speed.

1.Cleaning the throttle: Remove the engine trim cover, remove the throttle, clean it with carburetor cleaner, dry it with a cotton cloth and install it.

Cleaning the throttle valve basically every time we go to the 4S shop, the maintenance staff will suggest us to do this. Under normal circumstances, the cleaning cycle of the throttle is 20,000 km.

2.Clean the carbon deposits inside the engine: Open the oil cap, pour the whole tank of detergent (mixed with the old engine oil), close the oil cap, idle for 10 minutes and turn off the engine.

Cleaning the carbon deposits inside the engine, the detergent dissolves the sediments such as sludge, gum, moisture and metal debris inside the engine, and can reduce the pollution of new engine oil and prolong the service life of the engine. Its cleaning cycle is generally once every 30,000 km.

Read the instructions clearly How many liters is the fuel tank of your car? Generally, a bottle of fuel additives is used for 50-80 liter fuel tanks. Cleaning the carbon deposits in the oil circuit includes cleaning the fuel injector, combustion chamber, spark plug, throttle valve and other parts.

The purpose is to solve the intractable diseases such as insufficient horsepower, fuel consumption, wheezing and poor acceleration or difficulty in starting caused by carbon, gum and dirt in the oil circuit system.

4.Cleaning the carbon deposits in the air intake system

Buy a bottle of air intake system cleaner, pour it into the liquid storage tank of the special cleaning equipment, connect it to the air intake system, and use the vacuum to suck the detergent into the air intake road to achieve the purpose of cleaning. Cleaning the carbon deposits in the intake system mainly refers to cleaning the carbon deposits inside the intake tract and intake manifold. The purpose is to remove carbon deposits from the intake system, increase intake flow and speed, and reduce engine shake and idle instability.

Hope it helps.

1. Fault judgment:

It is usually manifested as: the engine is found to work abnormally or the power is insufficient, the engine works unevenly at high, medium and low speeds, and the rhythmic vibrating muffler discharges black smoke and discharges guns. The lack of cylinder in the engine can lead to large fuel consumption, black smoke, weakness, horsepower decline, the vehicle cannot increase speed, serious shaking, and increased driving noise.

And it is very bad for driving safety. Especially on the road section that needs to be sloped, the engine load of the vehicle with a lack of cylinder increases, the body shake is more obvious, and it is very easy to have an instantaneous dead fire.

Second, the lack of cylinder operation of the engine will bring great harm

1.The speed and power of the engine decreased.

2.Increased fuel consumption and emissions of pollution.

3.Aggravate the wear of running parts and shorten the service life of lubricating oil.

Third, the maintenance method: first check the circuit fault, and then check the valve tightness (cylinder compression ratio), if there is no problem with the above inspection, it is more troublesome, belongs to mechanical aging or damage, need to be overhauled.

It shows mechanical failure, spark plug replacement, engine shaking, and cylinder pressure is OK.

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.

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.

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.

Aging of engine components.

Car jitter is also associated with aging of the engine feet. 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.

Tire failure. First of all, it may be that the tire balance is not good, and the owner needs to do a four-wheel alignment and dynamic balance as soon as possible.

The other condition is more severe, possibly due to deformation of the steel rim, which typically occurs in vehicles that have been used for a long time. Generally, when the car is replaced with new tires and new steel rims, it is necessary to do a tire balance, otherwise the steering wheel will be prone to shake when the counterweight is uneven. Body shake will have an impact on driving comfort and handling judgment.

Summary. This is mainly due to the poor combustion of the engine, which caused this phenomenon. Clean the carbon deposits inside the engine, then clean the fuel injector, and clean the throttle.

Hello, don't click to end, I'm textual to give you the full answer, 2-3 minutes.

If this phenomenon occurs, this is mainly due to the failure of the engine, which may be a problem with the residual width of the spark plug or a problem with the ignition coil, or it may be that the atomization of the nozzle is not good. There is also the lack of cylinder pressure and the oil pump pressure of this engine. Specifically, it is necessary to check these aspects, and these aspects should be checked in detail.

I went to the car repair master to check Na Yunqiao, the master asked, how long the car did not drive, I said two months, the master checked the spark plug four are working hole keys, the master said to open two days, I drove 20 kilometers, the shaking is not so shaky, but to drive fast, quietly lead, the fault light, has been shining.

This is mainly due to the fact that the engine burns badly, and the phenomenon of belt stimulation occurs. Hold the carbon deposits in the engine and clean the lead, and then clean the fuel injector, and the throttle is basically fine.

I'm in the car right now, I'm on fire, I'm kicking the accelerator, 4-5 thousand rpm, and the fault light keeps flashing.

This is mainly due to the failure of the engine and the combustion is not good, mainly to clean and inspect the following aspects.

Okay, thanks. You are welcome.

Ask, how much does the repair shop cost, how long does it take, and how long can it be cleaned?

It's probably about three or four hundred yuan. This one is very fast, which is an hour or two.

Summary. The water temperature of the car is controlled by several parts. When the water temperature is too high, the thermostat opens to cool the engine by allowing cold water to flow into the engine.

The overheated water flows back to the radiator tank to dissipate the heat. At traffic lights or slow driving, the car moves forward slower and lacks wind speed to help dissipate heat from the radiator tank, at which point the fan of the radiator should automatically start to dissipate heat. The design of the car is such that even in the summer, when the car is stationary, the water flow and heat dissipation functions can far keep the engine from getting too hot.

Therefore, it is abnormal for the water temperature of the car to be too high.

Hello, the answer has been sorted out for you. Generally, such a problem should be checked whether there is a problem with the thermostat, and the Lu family cannot be completely opened, resulting in the obstruction of water flow. Or the water tank raw potatoes are rusty and the water is not smooth, and the heat cannot be discharged normally.

The water temperature of the car is controlled by several parts. When the water temperature is too high, the thermostat opens to cool the engine by allowing cold water to flow into the engine. The overheated water flow is returned to the heat dissipation tank.

At traffic lights or slow driving, the car moves forward slower and lacks wind speed to help dissipate heat from the radiator tank, at which point the fan of the radiator should automatically start to dissipate heat. The design of the car is that even in the spring shirt, when the car is stationary, the water flow and heat dissipation function can keep the engine from being too hot. Therefore, it is abnormal for the water temperature of the car to be too high.

Hello dear, there is a second kind of problem that our cavity is rotten and the third cylinder valve is leaking. Causing the cylinder pressure to be too low can also cause this problem. If we want to solve the problem, we use this cylinder pressure gauge to measure the infiltration, and the pressure of the third cylinder, if the pressure is relatively low, we need to disassemble the cylinder head and replace the valve.

To solve this problem, dear here, I wish you a happy life and all the best <>
