1. The combustible mixture is too rich. The remaining unburned parts will accumulate on the spark plug electrode and be carbonized, causing the spark plug to flash abnormally until it is damaged by carbonization. The reasons for the fuel mixture being too rich are usually that the carburetor oil level is too high, the carburetor main air volume hole is clogged, and the air filter element is seriously clogged. Additionally, the carburetor choke is blocked and cannot be fully opened, or the enrichment valve is not working properly, which is also the reason why the fuel mixture is too rich.
2. Engine oil leak. During engine operation, if blue or black smoke is emitted from the exhaust pipe, this indicates that excess engine oil has entered the cylinder, which will cause the productionfrom a large amount of carbon deposits by the spark plug electrode or its moistening. by engine oil and unable to produce sparks. This phenomenon is commonly referred to as engine oil channeling. For two-stroke engines, check whether the oil volume of the oil pump is too large and whether the rod sleeve seal and check valve are defective. For four-stroke engines, check the piston rings on the piston, especially the oil ring, whether it is worn or not. Then remove the intake valve and check for carbon and wet grease deposits on its head and back. If the valve and valve guide are severely worn, the valve guide seal is hardened, or the seal lip is excessively worn, the mounting gap will be too large and the effect of The seal will be lost. Both of these abnormal situations will eventually cause oil to be sucked intothe valve rocker arm chamber into the cylinder along the valve stem during intake air summing, causing oil combustion. In this regard, the valve guide, oil seal or valve must be replaced respectively depending on their wear.
3. In the ignition system, the magneto is demagnetized, the wire connections inside the ignition coil and the electronic ignition, the generator output end and the coil input end are demagnetized. The ignition is loose and the ignition timing is incorrect. If it is not properly timed, it will affect the ignition performance, and poor ignition performance will directly cause carbon deposits on the spark plug electrode.
4. Pay attention that the spark plug model and calorific value comply with the instructions for use. If the selected calorific value is lowerur one or two gears to that specified in the instruction manual, the temperature of the spark plug will rise very high and the heat cannot be dissipated in time, causing abnormal combustion and eventually melting of the spark plug. spark plug electrode. and cause premature damage. When the spark plug itself is installed and used, some defects are not easy to detect and also affect the ignition performance. For example, if the spark plug is poorly sealed or the spark plug is solid, it should be adjusted or replaced in time. 5. If the crankcase oil is overfilled and the breather pipe is blocked, the pressure in the crankcase will increase and the crankcase will not be balanced.
Is there only one type of generator for Toyota RZJ95 2700?
1. Abnormal noise from the body
Abnormal noise from the body is the most important. common, generallydue to the bodywork. Insufficient rigidity, long-term intense driving or prolonged walking on bumpy roads will cause the steel frame of the body to be slightly deformed. The most direct impact is abnormal impact or friction between the door and the bodywork. the car, or abnormal friction in some welding or screw parts, may also cause abnormal noise; some cars have more wind noise, which is related to some extent to the shape of the car.
Solution:
These abnormal noises are not terrible and will not affect the overall performance of the vehicle. It has a big impact, but it is difficult to deal with and difficult to cure . The only way is to add rubber pads or sponges to areas of abnormal friction or impact.
2. Abnormal noises in the car
Abnormal noises in the car are the most common, and there are manyplaces where abnormal noises occur, such as improperly installed decorative panels and co-driver's glove box Loosening, seat belt buckle impact, etc.
Solution:
Reset it automatically or fill it with soft objects.
3. Abnormal brake noise
If there is a “squealing” sound when applying the brakes, it is most likely caused by excessive wear of the brake pads, resulting in excessive gaps. Of course, improper use or deformation of the brake disc material, as well as unqualified hardness, porosity, friction characteristics and compression characteristics of the brake pads may cause abnormal noise.
Generally speaking, the lifespan of front brake pads is 30,000 kilometers and that of rear brake pads is 120,000 kilometers.
Solution:
Abnormal brake noise can usuallycan be resolved by replacing the brake pads. If the brake disc is damaged, it must also be replaced. When replacing, be careful. Model and other issues, otherwise the disparity will always persist. There will be an abnormal noise.
4. Abnormal suspension noise
The suspension system continues to operate while driving and the rubber bushings between the shock absorbers and each connecting rod inevitably wear out as the bushing ages or. falls, there will be abnormal metal impact sounds. If the shock absorber is broken, there will be a "dong dong" or "click" sound on bumpy roads.
Solution:
Generally, abnormal suspension noise cannot be solved by yourself. You need to go to a repair shop or 4S workshop to have a specialized master replace the parts. If this occurs, it must be resolved as quickly as possible. It is better to strengthen inspectionsduring daily maintenance to avoid the occurrence of abnormal noises.
5. Abnormal noise from tires
Abnormal noise caused by tires is generally tire noise. The noise generated will also depend on the car's driving speed, tire type, tire pressure and road surface. conditions, etc. Factors produce various noises of different strengths and weaknesses. When there is a faint “pop” noise, it is mainly due to tire tread deformation, bagging, heavy wear, or insufficient air pressure. If there is a “clicking” sound, the tread may be mixed with small stones or nails. .
If the wheels make a collision and metallic friction noise while driving, it is likely that the shock absorbers and bearings are damaged. Car owners should be careful when reIf you encounter these problems, even the simple act of driving nails can be dangerous.
Solution:
If you find that the tread is mixed with small stones, you can clean it yourself. Other issues should be brought to the attention of the car owner and requested to be handled by professionals.
6. Abnormal noise from steering wheel
Abnormal noise will be detected when the steering wheel is turned left and right. When an abnormal noise occurs halfway, it may be. essentially considered an abnormal noise coming from the steering gear. While it is difficult to determine the source of the abnormal noise after the steering wheel is rotated, the most common response obtained when going to a 4S shop for testing is friction of the steering wheel rubber sleeve. the ball joint of the steering rod.
In addition, abnormal noises may also be caused by oil leaking from the jacketof the steering gear, insufficient tightening of the electric assistance belt or aging.
Solution:
The tie rod ball joint is getting old and the steering gear has problems and needs to be replaced in time.
7. Abnormal noises in the engine compartment
The situation of abnormal noises in the engine compartment is complicated and requires careful investigation.
If the belt squeaks or whistles, it is usually due to belt slippage. If it is an air leak noise, it may be caused by a blockage or breakage in the exhaust system or vacuum tubes; If there is friction and abnormal noise from external metal parts when the engine is running, this can usually be caused by damage to the generator, water pump, etc.
Solution:
Find a professional to repair it as soon as possible
8 Abnormal noise in the gearbox
If thegearbox is broken. is used while the car is moving If there is a "rustling" sound inside and a whistling sound when changing gears, this may be caused by worn gearbox bearings or gears or by rolling points.
If the gearbox makes an abnormal noise when accelerating and changing gears, the gearbox oil may contain metal powder, indicating excessive gear wear. the brake belt of the gearbox, clutch and other components.
Solution:
The gearbox is precision equipment, so no matter what abnormal noise occurs, it should be repaired in time.
The fuel tank of a hybrid car's generator contains water. How to cope ?
There are several types. There are many non-original parts like this on the vintage car market. YOUcan definitely buy one for 1000, and the quality is not bad.
The 70 amps you mentioned is the maximum power output of the generator. It does not generate 70 amps whenever it is running. The generator automatically adjusts power output based on your power consumption. and do nothing else, it will generate less than 10A. If you turn on the air conditioner, all electrical devices such as headlights and speakers only generate 30-50A, which is enough to charge the battery .
So can be installed with generator exceeding 50A
Hello, hybrid car There are many forms of car engines, but their working principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: use suitable magnetic and conductive materialss to form magnetic circuits and circuits that conduct electromagnetic induction between them to generate electromagnetic energy and achieve the purpose of energy conversion. According to the different starting and working modes of motors, they can be divided into single-phase capacitor-started asynchronous motors, single-phase capacitor-started asynchronous motors, single-phase capacitor-started asynchronous motors, single-phase split motors. phase asynchronous motors and three-phase motors.
According to the rotor structure, the motor can be divided into cage induction motor, which is what you use, and wound rotor induction motor. A squirrel cage is a closed coil.
1. When a three-phase asynchronous motor is connected to a three-phase AC power supply with a phase difference of 120 degrees in electrical angle, the three-phase stator winding passes through the three-phase magnetomotor motor. force generated by thethree-phase symmetrical current and generates a rotating magnetic field. The magnetic field rotates clockwise along the inner circular space of the stator and rotor at a synchronous speed.
2. The rotating magnetic field and the rotor conductor have a relative cutting motion. According to the principle of electromagnetic induction, the rotor conductor.The body (the rotor winding is a closed path) produces induced electromotive force and produces induced current. The direction of the induced electromotive force is determined by the right-hand rule.
3. According to the law of electromagnetic force, under the action of the induced electromotive force, an induced current will be generated in the rotor conductor which is basically consistent with the direction of the induced electromotive force. The current-carrying rotor conductor is affected by the electromagnetic force in the magnetic field generated by the stator (the direction of the force is determined by the left-hand rule. The electromagnetic force forms an electromagnetic torque on the motor rotor shaft, driving the rotor). The motor rotor rotates in the direction of the rotating magnetic field when the motor when there is a mechanical load on the shaft, the mechanical energy is emitted outward. Since the magnetic flux in the part without short-circuit ring is ahead of the magnetic flux in the part with short-circuit ring, the rotating direction of the motor is the same as the direction of the rotating magnetic field.
