Garbage truck: How to eliminate the trouble caused by its shaking?
Garbage trucks may suddenly shake during work, although sometimes it does not last long, but it needs attention. If you do not pay attention to the detection, it will cause a big failure. So what is the cause of the jitter of the garbage truck? How should you troubleshoot problems caused by jitter? Let's take a look.
- When the garbage truck is driving, the body shakes
If you find that the car body shakes or shifts slightly during driving, it is usually a fault caused by the tires. First of all, it may be that the tire balance is not good. The owner needs to do a four-wheel alignment and dynamic balance as soon as possible. If the vehicle does not deviate, do the tire dynamic balance. The other situation is more serious, which may be caused by the deformation of the steel ring, which requires the owner to go to a professional repair shop for inspection. This situation generally occurs in vehicles with a long service life. Generally, when replacing new tires and new steel rims, a car needs to be balanced once, otherwise the steering wheel will easily shake when the counterweight is uneven. Body shake will affect driving comfort and handling judgment. The third situation is caused by the unbalanced deformation of the transmission shaft. Generally, this situation occurs in more cars that have been in collision with the chassis.
- Body shake at idling speed
Idling body shake is a common situation encountered by many car owners. If the owner of the vehicle starts or stops the vehicle without turning off the engine, if the vehicle body shakes significantly, it may mean that the vehicle has the following three conditions:
1.Ignition system problem
Check the working conditions of the spark plug, high-voltage wire and ignition coil. The ignition system is not working properly, and the spark plug is not in good condition, which can also cause this kind of failure.
Solution: Check whether the spark plug has excessive carbon deposits and replace the spark plug.
2.Engine carbon deposits are serious
The most common cause of car jitter is that the throttle is too dirty or the fuel injector is too carbon. When there is too much carbon deposits inside the engine, the gasoline sprayed by the cold start injector will be absorbed by the carbon deposits, causing the cold start mixture to be too lean, making it difficult to start. In this case, only gasoline that waits until the carbon deposits are absorbed When the car is saturated, it is easy to start the car. The gasoline adsorbed on the carbon deposits after the car is sucked into the cylinder by the engine's vacuum suction and burns, and the mixture becomes thick. The combustible mixture of the engine is sometimes thin and sometimes rich, resulting in cold start. Idle jitter. The lower the temperature, the greater the amount of oil required for a cold start, and the more carbon deposits will affect the smoothness of the cold start.
Solution: Clean the oil circuit and check whether the idle speed motor has carbon deposits and should be cleaned.
3.Unstable oil pressure
If you have cleaned the carbon deposits in the engine, washed the throttle, changed the fuel pads and spark plugs, etc., and still found that the vehicle 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 fuel pump supplies fuel Abnormal pressure or incorrect value of intake pressure sensor and poor operation will cause body shake.
Solution: Check the oil pressure and replace parts if necessary.
4.Engine components are aging
Car jitter is also related to the aging of the engine feet. The engine feet are actually the shock absorber system of the engine. The engine feet are responsible for absorbing the slight jitter of the engine when it is running. If there is a problem with the engine feet, these vibrations will be transmitted to the steering wheel and the cab, causing jitter when idling.
Solution: Replace parts
The above is the method to eliminate the trouble caused by the jitter of the garbage truck. The jitter of the driver friends can be large or small. It must be paid attention to. It is best to check and solve the problem in time to avoid affecting the driving. If there is no problem, you can also feel at ease .
