Does the car shake caused by the frequent idling of the car engine affect the vehicle?

How often does the engine shake at idle? Probably not.

However, jitter has a certain amount of damage to the oil circuit and circuit system, as well as to the engine.

For example, spark plugs can create carbon deposits.

Fuel injectors. Carbon build-up in the cylinder chamber.

Machine glue stacks and so on.

It's actually a problem.

You can clean the throttle.

The main thing is to clean the idle motor.

It should improve this problem.

The speed is slow, and the machine shakes.

Because when the machine turns.

There should be a balance in the crankshaft.

Does the car shake caused by the frequent idling of the car engine affect the vehicle? The main reason why there is no problem with the accessories of the new car is that it burns badly, and the quality of the fuel added recently is related, and it is not that refueling 98 at a large gas station is equivalent to no problem. The phenomenon is that if the oil is not extinguished, and the oil is not extinguished, then the fuel injector may be a little blocked, or there may be slightly more impurities in the oil circuit and fuel tank.

Impurities in the oil circuit will affect the combustion jitter. How can there be so many impurities in a new car? This has nothing to do with the new car, even if the large gas stations have cleaned the underground oil tank, no one will guarantee that the oil impurities added each time will not exceed the standard.

And the gas station has to be clean, not to mention that the fuel tank of our car is not clean, and the oil circuit is definitely not clear... Direct injection engine is not like EFI, direct injection is very sensitive to fuel combustion, and a high compression ratio is also an important factor in sensitive fuel... Therefore, it is recommended that you use this kind of detergent cleaning agent to clean the fuel tank, which is generally clean after 500 kilometers, and there is no big problem with the new car.

After cleaning and combustion, it will not shake,,, and do not add high-grade fuel, which does not have the function of clean oil circuit, which can only cover up the problem of poor combustion, which will cause greater damage. Some gas stations also use this type of cleaner to clean the tank.

What the hell is the car shaking? - Idle jitter.

Jitter at idle is caused not only by problems with the engine's suspension system (engine feet), but also by problems with the operation of the engine itself. Poor engine operation can be divided into three reasons: oil, electricity and air, and the most likely cause of idle jitter is the problem of idle motor failure.

If the engine shakes under full load on the electrical system and the revs drop significantly, it is certain that something is wrong with the acceleration system. The acceleration system is actually an idle control system in the case of the current fuel-injected engine.

The bypass air valve of the idle speed control system, also known as the speed-increaser, is also known as the idle step (in) motor (IAC).

When the engine increases the load on the electrical system, it will open the bypass air valve (also known as the speeder) of the idle control system to increase the air intake of the bypass air, and after increasing the air intake of the bypass air, the fuel injection will also be increased, so that the engine speed will rise to keep the speed from being affected by the electrical load and causing jitter; These actions happen at the moment when you turn on any of the electrical appliances, and they are all computer-controlled.

There are only two reasons that will cause the speed to drop and the engine to shake, one is the failure of the speed improvement system, and the other is the computer failure; This is a temporary rule out of computer failure, as the probability of computer failure is not high. The failure of the speeder can be divided into two aspects, one is that the speeder itself is faulty and broken, so it will not move when it should be moved; The other is that the bypass air duct controlled by the speeder is blocked, resulting in poor air intake and engine shaking.

The cause of the blockage of the bypass air duct can be divided into two parts, one is the carbon accumulation at the top of the valve, and the other is the unclean blockage inside the pipe. In general, as long as the bypass pipe is cleaned, the jitter problem can be improved.

The performance of the engine itself is determined, and when the resonance frequency is reached, it will naturally shake, which is not a fault, but an ordinary physical phenomenon.

When the air conditioner is turned on, the engine load increases, and the power coefficient of the car design itself is insufficient due to carbon deposition, so it shakes. There is carbon deposition in the intake valve room, fuel injector, and combustion chamber, which will definitely solve the problem.

Cool car start-up difficulty: fuel injector carbon blockage, intake valve compartment carbon deposition caused by car Bell can definitely be solved.

Cool car idle shaking: There is carbon deposits in the intake valve compartment that causes the car Bell to definitely solve the problem.

How many kilometers is your car?

It could be that the throttle is dirty, or there is carbon buildup on the piston.

Have it checked by a professional technician.

Top 4 reasons why a car body shakes when idling:

Severe carbon deposits in the engine: The most common cause of car shake is a dirty throttle valve or excessive carbon buildup in the fuel injector. When the carbon deposit inside the engine is excessive, the gasoline that the cold start fuel injector head sprays out will be absorbed by the carbon deposit in large quantities, causes the mixture of cold start to be too thin, makes the start difficult, in this condition, only wait until the gasoline that the carbon deposit absorbs is saturated, it is easy to get on the car, and the gasoline adsorbed on the carbon deposit after the car will be sucked into the cylinder of the vacuum suction of the engine again for combustion, and the mixture becomes thickened again, and the combustible mixture of the engine is dilute and thick, causes idle shaking after cold start.

In addition, the lower the temperature, the greater the amount of oil required for the cold start, and the more the presence of carbon deposits will affect the smooth cold start.

The solution is to clean the oil circuit and check whether the idle motor has carbon deposits that should be cleaned.

Ignition system problems: the working condition of the spark plug, high-voltage wire and ignition coil, poor ignition system work, and poor spark plug flashing will also lead to this kind of failure.

The solution is to check the spark plug for excessive carbon accumulation and replace the spark plug.

Unstable oil pressure: If you have cleaned the engine carbon deposit, washed the throttle, changed the oil cushion and spark plug, etc., and still found that the body shakes when idling, it is recommended to 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 caused.

The solution is to check the oil pressure and replace the parts if necessary.

Aging of engine components: Car shake is also associated with aging of 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.

1. Oil road problems: mail road problems are generally caused by oil road blockage, resulting in poor oil supply, which is manifested as engine shaking, unstable standby speed, and stalling during driving; In addition, engine shake will also occur when the oil pump fails, and the oil pump problem should be judged by disconnecting the oil pipe and checking the flow rate and flow rate.

2. Circuit problems: check whether the right fit is accurate, and the general ignition is not normal is the right fit problem; Check whether the spark plug has aged, whether the gap is the same, and whether the gap has changed; In addition, if the distributor does not work properly, it will also cause the engine to shake.

3. Mechanical reasons: check the running status of the engine, whether there is abnormal sound, valve sound; Check the working condition of the belt and whether it is loose.

If there is no abnormality in the ignition system and fuel injection system, check the carbon deposits.

The car engine shakes when idling, what is the reason for it If the oxygen sensor is cleaned and does not shake temporarily,. Basically, it is certain that the vehicle oil circuit has been dirty, resulting in poor emissions, and the sensor is seriously polluted. It is recommended to wait until the sensor failure occurs again, directly clean the oil circuit, you can use this kind of cleaning to the fuel tank, so that the emission will be reduced after driving, the sensor will naturally return to normal, and the jitter will disappear.

There are several possibilities for engine shake.

1."The air filter is dirty, clogged, and not replaced in time, or the high-voltage line is broken and affects the ignition and causes the engine to shake.

2.Engine shake caused by spark plugs not being replaced in time or low fuel pressure.

3.Dirty throttle valves, clogged injectors, or low cylinder pressure can cause engine jolting.

Air filter dirty:

The air filter is designed to protect the engine to reduce wear, generally replaced in about 10,000 kilometers, if the replacement is not timely, there will be insufficient air intake to cause low idle speed, and the engine shakes, as long as the filter element can be replaced.

High-voltage line break: High-voltage line break refers to the high-voltage wire core break, which can affect the ignition and cause the engine to shake.

Spark plug life:

The spark plug has a lifespan, and the ignition efficiency is significantly reduced after more than 3-40,000 kilometers, and can affect the ignition, which is the most common failure.

Low idle speed: The engine idle speed value has been set in the computer, and when the number of revolutions is low to a certain range, the car computer will automatically adjust it. If the idle speed is too low and the jitter is beyond the control range of the computer, some cars have adjusting screws on the throttle to adjust the idle speed, and some cars can not adjust, this kind of car can check the idle valve, throttle, air flow meter, vacuum sensor, adjust the ignition time (car with distributor), you can increase the idle speed.

Low idle speed can occur even when the water temperature is low, so you can check and replace the thermostat.

The water temperature is not normal:

There is a normal range of engine operating temperatures, and high water temperatures will cause earlier ignition times, changes in the oil-air mixing ratio, thinner oil viscosity, and worse lubrication performance. The general fault cause is the jitter caused by the lack of antifreeze, the thermostat cannot be opened, the fan does not rotate, and the temperature of the temperature control switch is inaccurate.

Fuel injector clogged:

The fuel injector of the EFI vehicle is a key component of automobile fuel injection, and the service life is very long, which can reach hundreds of thousands of kilometers. However, because there is gum in the gasoline, the fuel injection hole of the fuel injector will be blocked, so the amount of fuel injected by each fuel injector is inconsistent, resulting in the inconsistent work of each cylinder and causing the engine to shake. The solution is to remove it and clean it.

Carbon deposits, grease blockages:

The throttle, idle valve, and air intake hole will be blocked by carbon deposits, oil scale, and poor air intake after a period of use, which will affect the stable idle speed and shaking. It is necessary to inspect and clean the above parts with cleaning agent, and there is no need to remove them for cleaning.

Low cylinder pressure: The engine has 3 cylinders, 4 cylinders, 5 cylinders, 6 cylinders, and 8 cylinders. Three-cylinder engines are the most obvious, followed by four-cylinders. Check the cylinder pressure with the cylinder pressure gauge, and solve the fault of low pressure with Xinba.

Xinba has a unique effect on low cylinder pressure and unbalance. It can be added to the engine oil or directly added to the cylinder to restore the balance cylinder pressure.

Hello, a dirty throttle will cause idle jitter.

Hello, this is idle too low and the throttle needs to be cleaned.

1. Ignition system failure:

Spark plugs are wearing parts, which need to be replaced regularly, if it is found that the spark plug has too much carbon deposition or the ignition gap is too large, it needs to be replaced, and it is also necessary to check the working status of the line, high-voltage wire and ignition coil, and the car computer can be used to determine the state of the ignition system.

2. The engine produces serious carbon deposits

Carbon deposition in the engine is the main cause of car shaking, when there is too much carbon deposition inside the engine, the gasoline emitted by the cold start line collapse injection head will be absorbed by a large amount of carbon deposition, resulting in too thin mixture for cold start, resulting in more difficulty during cold start.

3. Hydraulic problem:

If the fuel supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is abnormal, or if the intake pressure sensor is wrong and the operation is not good, the body will shake.

What to do if the engine is shaking at idle.

There are several reasons why the hair chain is judging:

1. The engine has serious carbon deposits, and the most common car with serious shake is that the fuel injector throttle valve is too dirty or too much carbon;

2. Ignition system problems, check the working conditions of spark plugs, high-voltage wires and ignition coils;

3. The oil pressure is unstable, if the first pressure of the pump is abnormal or the error and poor work of the inlet pressure sensor will cause the body to shake;

4. Aging of engine parts; The excessive carbon deposits in the emissions of the bright motor absorb the carbon in the gasoline of the cold-start injector, which leads to a dilute cold-start mixture and difficulty starting.

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

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 fumes coming out of the car are obviously intermittent, and the exhaust pipe shakes violently, and the engine shake can be clearly felt, 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 hand-wide 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, there is no specific experience in the research and development parameters of the clean engine from the new car, coupled with the continuous improvement of emission standards, can not adapt to the change of fuel, all manufacturers of the engine are unable to solve this jitter problem in the short term, plus the fuel quality is not very good or the initial fuel of the new car factory 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. The occurrence of excessive carbon deposits is especially common for China VI vehicles. We can only gradually alleviate most of the problems by maintaining clean oil circuits. The use of PNF dope fuel additives can solve the problems caused by carbon deposition.
