The reason why the engine body of the refueling door shakes while the Citroen Sega even heating car is running

The reason why the car steps on the accelerator and shakes: the oil line is blocked, Resulting in poor oil supply; air leakage or blockage in the air intake system; damage to the ignition coil and spark plug, excessive carbon accumulation in the throttle valve, failure of the fuel injector, blockage of the gasoline filter, etc.

is the operation of the engine. If the engine needs to ensure its work, it needs to have enough air, enough gasoline and an ignition system in good condition. Any problem will cause the engine to shake.

I'm a 2011 0 manual Sega car, and I've walked more than 50,000 kilometers. Today, the fault light is on, and the fire is empty. I repaired it in my county, cleaned the throttle valve, and replaced the spark plug. As a result, the fault light is on, and the refueling doesn't work. The master said that there was something wrong with the high-pressure bag. Is it true? Ask for a high finger point.

What is the reason for the engine shaking when refueling?

1. The reasons for the engine shaking when refueling are as follows: Poor ignition: After a car drives to a certain mileage, the ignition ability of the fire plug will decrease. In the process of acceleration, the fire plug jumps weakly, which will cause poor combustion and shaking. Remove it and check it. If the electrode is black and wet, it needs to be replaced.

2. CarsThe main reasons for jitter when refueling and speeding up are: failures such as bending, twisting and breaking of the car's semi-axle, as well as spline tooth wear or twisting, leakage or blockage in the air intake system, decreased performance of spark plugs or the use of inferior spark plugs, and abnormalities or failures in the fuel system of the car.

3. Oil line problem: The postal route problem is generally caused by the blockage of the oil line, resulting in poor oil supply, which is manifested as engine shaking, unstable standby speed, and shutdown during driving; in addition, engine shaking will also occur due to the failure of the oil pump. To judge the oil pump problem, disconnect the oil pipe and check the relevant flow rate.

4. The most common cause of car shaking is that the throttle valve is too dirty or the fuel injector has too much carbon.

5. When the idle speed is over the bottom, it may be because the engine cannot receive the air conditioner on signal, or the air conditioner on signal voltage is weak and the engine speed cannot be increased, causing the engine to shake under heavy load.The main reasons for the vibration of the engine after refueling are: 1.

What is the reason why the car shakes when you step on the accelerator deeply

1. The reason may be The engine lacks a cylinder or the high-pressure line is not on fire, causing acceleration and shaking; in addition, if the throttle is closed at this time, the jitter will decrease or disappear, and the speed of the vehicle will change with the degree of damage to the faulty parts when the fault occurs.First, check whether the left and right semi-axes are bent.

2. Fuel system, ignition system, air intake system, any part of these three systems has a problem, which may cause the car to shake when you step on the accelerator. Here are a few common reasons. Ignition system: spark plug problem. It is possible that the spark plug has reached its life; it is possible that the spark plug has accumulated too much carbon.

3. The reasons for the shaking of the car stepping on the accelerator are as follows: 1 The problem of the oil line. The problem of the postal route is generally caused by the blockage of the oil line, resulting in poor oil supply, which is manifested as the engine shaking, unstable waiting for speed, and the engine is turned off during driving. In addition, the failure of the oil pump will also cause engine shaking. To judge the problem of the oil pump, disconnect the oil pipe and check the relevant Flow rate 2 circuit.

4. Causes of body shaking and vibration during acceleration;When driving, the engine of the car will shake and vibrate normally, and sometimes it will not start. Maybe the throttle valve is too dirty, and the fuel injector and air intake have too much carbon.

Why does the vehicle shake seriously when refueling while driving?

If the foot glue is damaged and the car accelerates, it can be considered whether the foot glue is broken. The function of the foot glue is to support the engine and gearbox and slow down the noise and vibration made when they run. When the foot glue is damaged, the function of noise reduction and shock absorption will be insufficient. Especially when decelerating, the jitter and noise are very obvious.

Under the action of long-term torsion fatigue and impact, the half-axle of a car is prone to bending, distortion and fracture and its flowers.Failures such as key tooth wear or twisting, so that when the car accelerates to a certain speed range, the front of the car will have regular jitter, and the shaking disappears or is reduced after the accelerator is released.

The engine has serious carbon accumulation. The most common cause of idling jitter is excessive carbonisation of the throttle valve or fuel nozzle.

Caused by loose belt slippage, excessive gap of some transmission wheels or idle wheels, or stuck and other reasons. Man-made operation reasons are not excluded: A. The reason for manipulating and driving causes abnormal engine speed, and even the possibility of body shaking. B. Speeding. The possibility of other aspects is not excluded, and the specific test results of the actual vehicle shall prevail.

The car will shake, the engine will be loud, and the tachometer will be slightly higher -- normally it will rotate from 600 to 900. If you are like thisIn this case, it is easy to have engine carbon accumulation when starting because the combustion of the engine is insufficient at low temperatures) Do not drag gears when driving, and when the engine shakes, the gear should be removed in time.

What's wrong with the car engine shaking when the refueling door?

The reasons for the shaking when the car is refueling are as follows: Oil line problem: The oil line problem is generally manifested as engine jitter, unstable idle speed, and shutdown during driving caused by the blockage of the oil line. In addition, the oil pump failure will also cause engine jitter to judge the oil pump problem by disconnecting the oil pipe to check the relevant flow rate. .

The engine needs to have enough air to ensure its operation. If there is a leak or blockage in the air intake system, there will be speed-up jitter when the car refueling door;When the performance of spark plugs declines or the use of inferior spark plugs, it will lead to weak acceleration, acceleration jitter and other conditions.

Oil line problem: The problem of the postal route is generally caused by the blockage of the oil line, resulting in poor oil supply, such as engine shaking, unstable standby speed, and shutdown during driving. In addition, the failure of the oil pump will also cause engine shaking. To judge the oil pump problem, disconnect the oil pipe and check the relevant flow rate.

The jitter of the refueling door during the driving process of the car may be caused by the following reasons: engine failure: the engine has a missing cylinder or a high-pressure line disconnection, resulting in shaking.

The car shakes when refueling at high speed, and it doesn't shake without refueling?

1. Unstable oil pressure is easy to cause the concentration of the mixed gas to be unstable, which not only causes jitter but also causes unstable idle speed.You can first consider replacing the gasoline filter. After all, the filter element may be blocked after using it for a long time. Then check the oil pressure that does not go through the gasoline filter. If it is not normal, it may be a problem with the oil pump.

2. Hello, there are several reasons for the shaking of the car at high speed: tire loss of roundness. Tire loss of roundness is not only a problem of rubber tires, but also caused by the deformation of the hub. If it is a problem with the hub, the hub must be replaced, because even the dynamic balance cannot solve the problem caused by the deformation of the hub. A series of problems.

3. The specific analysis is as follows; sensor problems; the sensors mentioned here include water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, poor contact or the signal is interrupted, the ECU of the car cannot accurately obtain the engine data. At this time It will cause the engine fault light to light up.

4. The most common reasons for car shaking may be the dirty throttle valve and too much carbon accumulation in the fuel injector.

5. Four-wheel positioning: the deviation of the wheel positioning data is large. In particular, the front wheel positioning angle is not accurate, and the front bundle is too large. This situation is that when accelerating, it feels that the vehicle is difficult to control, and the shaking is generally not large, but it is awkward to drive.

6. Most of the reasons for excessive wear of the inner ball cage are due to the damage of the dust cover on the semi-axle shaft, and the owner did not replace it in time; therefore, if you see the dust cover bursting and oil leakage, you must replace it in time, and don't lose big because of small; in addition, insufficient fuel injection and insufficient oil pressure in the oil line will also cause the car The motivation shakes when accelerating.
