Your car is a new car. There should be no problems with the circuit. But you can also check the high voltage ignition. The method involves removing the high voltage cap about a centimeter. from the top of the spark plug. Start the engine and increase the throttle. Check if the high voltage ignition is not a continuous ignition. If there is a shutdown, it means there is a problem with the high pressure fire. it's a continuous ignition, everything is fine.
There may be a problem with the carburetor and from what you've said it's probably a bad carburetor adjustment.
What should I do. what to do if the spark plug of the Loncin Domineering motorcycle is very small and does not ring? I repaired a motorcycle today but it doesn't ring and the light is very small I replaced the high voltage pack and turned on the ignition
It is possible that some parts inside the brake padshave fallen, which will cause abnormal noises at the front of the Loncin Promise 150gt but no abnormal noise when braking.
1. Correctly distinguish between normal and abnormal sounds.
When the car is running, the vibrations of various mechanisms will make sounds of different kinds, but the sound does not mean that the car is defective. In order to avoid unnecessary disassembly, you must first distinguish what is normal. abnormal sounds and sounds. Normal vibrations of various system components (such as noise on the engine surface), gear impact noises when changing gears, intake and exhaust noises using gas as a work source, gear meshing noises, etc. are all normal sounds. Abnormal noises (abnormal noises) can be divided into light noises, normal noises and malignant noises according to their impact on car performance. Slight noises,such as the flashing noise of high voltage electrical leakage, the slight rolling noise of bearings, etc., generally have a small volume, the wear degree of the parts is not large, and there is no significant change for a long time. Such defects can still keep the car without repair normal driving.
3. When diagnosing abnormal car noises, attention should be paid to creating good auscultation conditions and trying to eliminate interference from other noises so as not to affect the accuracy of judgment.
It is best to consciously amplify or reduce the sound, that is, use a screwdriver or other metal rod as a stethoscope to contact the sound part to amplify the sound , or use a single cylinder to cut off the fire to reduce the sound, to meet the diagnostic needs. The monitoring site should be kept quiet to minimize human interference.nes.
3. Below we list some common abnormal car noises that are easy to eliminate along with simple methods of identification and elimination.
1. There are abnormal noises in the body
Explanation of symptoms: When you drive and press the accelerator or brake, there are always abnormal noises from some parts of the body. .The sound is not loud and does not affect normal operation, but there is always a little worry that something is wrong.
Problem analysis: This problem usually occurs because the rigidity of the body is insufficient, causing the vehicle to deform while driving, the door and frame to rub or shake, or desoldering to certain places causes friction between the steel plates. , etc. .
Some cars also have louder wind noise. To some extent this is related to the forme from the car. In some cars, body parts are not properly secured and may be the cause. abnormal noise. Generally, tighten the screws. This can be resolved.
Solution:
First check if there is anything loose, easy to roll and noisy in the trunk or back seat of the car. objects to eliminate the noise caused by certain poorly fixed elements.
If you find that the friction between doors and windows causes abnormal noises, you can stick tape on the doors and windows or put rubber on the friction parts. You may be able to reduce or eliminate abnormal noises. , but the result is only a temporary solution and not the root cause of the problem. If none of the above problems are found, you should go to a regular repair shop for inspection and troubleshooting.
2. There are abnormal noises in theengine
Explanation of symptom: There is a greater possibility of abnormal noises in the engine compartment. Most people also judge that abnormal noises come from the engine. engine compartment depending on the source of the sound, usually a metallic screech or hiss.
Problem Analysis: Abnormal noise coming from the engine compartment will include a loud whistling sound from the belt, which is usually caused by belt slippage. There will also be a sharp sound of dry rubbing of metal parts when the engine is running, which is usually due to damage to the bearings of the generator, water pump, and power steering pump. If the sound of air leaking is caused by the engine running, it may be the result of a blocked engine; exhaust system, vacuum tube leak or rupture.
Solution: Abnormal engine noise indicates that the technical condition of a certainn engine mechanism has changed. This is mainly due to excessive wear of certain parts or poor assembly and adjustment. Certain abnormal noises can predict the possibility of accidental engine damage. Therefore, when abnormal noises occur in the engine, they should be repaired in time to prevent the fault from extending.
It is worth remembering that if there is an abnormal noise in the engine, the car owner is unlikely to be able to solve it himself and it is better to send it to the factory for maintenance.
3. There is an abnormal noise in the gearbox
Explanation of symptoms: If there is a “rusting” sound inside the gearbox while the car is driving, but it disappears after the clutch or accelerator is pressed, replace it. A whistling sound will be heard when changing gears.
Analysis of the problem: If the source of the noise encountered durings of the drive is the gearbox, this may be due to worn gearbox bearings or gears, or bearing points. If the transmission makes abnormal noises when shifting at high speeds, the transmission oil may contain metallic powder, indicating excessive wear of components such as the gear belt clutch. brake of the gearbox.
4. There are abnormal noises in the tires
Symptom description: The tires emit rhythmic noises, and the faster the vehicle speed, the higher the frequency.
Analysis problem: When a car tire contacts the ground, it will produce various noises of different strengths and weaknesses depending on the type or irregularities of the road, the speed of the car, the type of tire and the air pressure of the tire itself. Therefore, no matter how perfect a car is, it cannot eliminatecompletely block out the noise generated by the tires and the ground while driving.
5. The engine guard makes an abnormal noise.
Explanation of symptoms: The engine guard has been installed for some time, but after a ride in the suburbs, there was a noise at the skid plate at my return. Strange noise.
Solution: Screws tend to move around in cars that move frequently. If you often hear "pop, pop, pop" noises coming from the air intake grille, in addition to the grille being loose, the air intake grille is loose. The car owner should always check whether the screws of the engine protection plate are loose or whether the engine protection plate and film are loose. If the abnormal sound is caused by loosening, in addition to tightening the screws , you should also place cardboard objects on the abnormal sound area to easily eliminate the abnormal sound.
6. The brakeshave abnormal noises
Symptom description: The vehicle makes relatively loud noises and abnormal noises when the brakes are applied.
Problem Analysis: Of course, abnormal noise when braking may also be caused by other reasons, such as improper use or deformation of the brake disc material, hardness, porosity, friction characteristics and compression characteristics are not qualified, the brake pads and brake discs are wet and rusty, the metal wire in the brake pad formula is too hard, and the mechanical scrapers of the pads brakes are among the reasons. To resolve this problem, simply brake vigorously several times in succession to eliminate the abnormal noise.
6. Brakes make abnormal noises
Symptom description: The vehicle makes relatively loud noises and abnormal noises when brakeseins are applied.
Problem Analysis: Of course, abnormal noise when braking may also be caused by other reasons, such as improper use or deformation of the brake disc material, hardness, porosity, friction characteristics and compression characteristics are not qualified, the brake pads and brake discs are wet and rusty, the metal wire in the brake pad formula is too hard, and the mechanical scrapers of the pads brakes are among the reasons. To resolve this problem, simply brake vigorously several times in succession to eliminate the abnormal noise.
Solution:
The brake pad is one of the most important parts of the brake system. Generally, the lifespan of the front brake pad is 30,000km and the lifespan of the rear brake pad is 30,000km. the brake pad is 30,000 km. The lifespan of the platese dynamic friction is 120,000 km. If there is a "squealing" sound when applying the brakes, it is most likely a warning sound coming from the brake pad wear indicator, which indicates that the brake pad brake has exceeded its usage limit. When this happens, car owners should go to the car dealership for maintenance as soon as possible, otherwise the brake pads will be exhausted, causing damage to brake components, abnormal braking effect and accidents.
Why does the motorcycle igniter keep burning?
Usually, as long as there is an electrical spark, it will ignite. If the electrical spark turns yellow, this may be a problem. the igniter, which can be replaced. If it's bright blue or white, then no problem. If it doesn't start, that's another problem. As follows:
1. Is the air filter dirty or clogged? You can withdrawremove the air filter and try restarting again.
2. Oil circuit. Check whether the negative pressure rubber tube connected to the throat is aged, cracked and leaking. Is the fuel tank three-way switch damaged? Is the carburetor oil filter clogged? Whether the fuel pipe is smooth. Are the carburetor measuring holes clogged? Is the carburetor float height too high or too low? Is the main oil needle worn? If the vacuum membrane is broken. Additionally, the carburetor mixture may not be properly adjusted.
3. Engine. Whether the cylinder body and cylinder head are sealed. Is the valve properly closed? If the piston ring or cylinder block is excessively worn, causing the cylinder to blow or even pull out.
The reasons why the motorcycle lighter keeps burning:
1. Heat dissipation is not good. The original rectifierof the vehicle must dissipate heat.
2. The power of the rectifier is low and should be replaced with a higher power.Short circuit voltage stabilizer rectifier.
3. The plug has poor contact, check if the plug is loose or rusty and replace it with a new plug if necessary.
Note: If the igniter is damaged, it is recommended to find a qualified technician to repair it. The repaired igniter will be fully functional and can still be used normally.
