How to use trade data for pricing strategy

. When the car reaches 80 kilometers per hour or higher, the body shakes. Four. When braking, the car tends to turn to one side, and you need to turn the steering wheel to keep the car stopped in a straight line. 5. When braking, the rear wheel is locked, pulley and other phenomena are found.6. The exhaust pipe makes irregular noise.

3. Symptoms: 1: Performance decline: the engine is abnormal, indicating a significant decline in the technical performance of some aspects: the consumption of fuel or lubricating oil is significantly increased compared with the normal situation. The performance is reduced, the acceleration response is sensitive, and it is quite laborious to overtake. There are some obvious abnormal symptoms, such as abnormal noise from the engine or chassis.

These common faults in cars

1. Cause analysis: When your vehicle uses warm air, this phenomenon is generally caused by a slight leakage of the heating tank in the cab. The fog on the front wind window glass is caused by the wind generated by the blower in the car to blow the leakage of the antifreeze out of the wind duct and condense on the front wind window glass. At the same time, people can also feel the special taste of anti-icing liquid.

2. Sudden change in working conditions: The so-called sudden change in working conditions refers to the sudden abnormality of the working conditions of the car, which is a common fault symptom. Generally, it is sudden, and you should deal with it calmly.

3. Common faults of automobiles Main faults: abnormal automobile performance Abnormal automobile performance is the poor power and economy of the car, mainly manifested in the obvious low maximum driving speed of the car and poor acceleration performance of the car; large fuel consumption and large oil consumption of cars. The ride comfort of the car is poor, and the vibration and noise of the car are obviously increased.

4. As a walking tool, cars provide convenience for our lives; but cars are also an electromechanical product. In the process of long-term use, it is difficult to guarantee that there will be no such and such problems. It doesn't matter if there are problems, the important thing is that we can find problems in time and find solutions. Method.

5. Common faults of cars include sudden working conditions, abnormal noise, odor, abnormal smoke exhaust, abnormal temperature, abnormal appearance, abnormal fuel and lubricant consumption, and leakage. Common faults are often encountered in use.

When did the car appear?

The automobile was invented in 1886. German Godlipp Daimler installed his own car engine on a four-wheeled carriage and drove at a suffocating speed of 18 kilometers per hour, and the first four-wheeled car in human history was born.

The world-recognized first car was born on January 29, 1886. German engineer Karl Benz applied for a German patent for its motor vehicle after years of research and development and experimentation. This is also the world-recognized first car.

year. Karl Benz, a German, successfully developed the world's first three-wheeled car in October 1885. On January 29, 1886, he applied for a patent for automobile invention from the German Patent Office. On November 2 of the same year, the Patent Office officially approved it, which was also the world's first automobile patent certificate.

The first car was invented in 1769. The Frenchman N.J. Guinew made a three-wheeled car driven by gas combustion to produce steam. In 1885, Daimler's Bentz in the same factory was also studying cars.

During this period, Japan also rose rapidly. By the 1980s, the production reached 11 million vehicles, surpassing the United States and ranking first in the world. During this period, automobile technology mainly developed in the direction of high speed, convenience and comfort. Streamlined body, front wheel independent suspension, automatic transmission and all-wheel drive all appeared during this period.

The world's first car was produced on January 29, 1886. History of automobile development The world's first automobile was successfully developed by German Karl Benz (1844-1929) in October 1885, which set the tone of automobile design. Even the current car cannot break out of this frame.

What are the common faults of cars

Engine faults: including gasoline pump faults, ignition coil faults, cylinder head faults, etc. Battery failure: including insufficient battery charging, battery damage, vehicle circuit failure, etc. Cooling system failure: including water pump failure, water tank failure, radiator failure, etc.

Car failure means that the car can't complete itsFunctional phenomena, such as engine difficulty in starting, car failure, car oil leakage and water leakage, lighting system failure, etc. There is something wrong with this car. Common faults include sudden changes in working conditions, abnormal sound, abnormal smell, abnormal smoke exhaust, abnormal temperature, abnormal appearance, abnormal fuel and lubricating oil consumption, and leakage.

Causes for automobile failure 1 Abnormal car performance Abnormal car performance is the poor power and economy of the car, mainly manifested in the significantly low maximum driving speed of the car and poor acceleration performance of the car; large fuel consumption and large oil consumption of the car. The ride comfort of the car is poor, and the vibration and noise of the car are obviously increased.

Cause analysis: After a period of use, the car will have a slight "gala" sound when the door glass rises and falls. Especially the driver's side is serious. This is mainlyBecause the wind and sand in the north are large, some fine dust and gravel are often left where the door glass and the sealing strip are in contact, causing noise when the glass is raised and lowered.

As a walking tool, cars provide convenience for our lives; but cars are also an electromechanical product. In the process of long-term use, it is difficult to guarantee that there will be no such and such problems. It doesn't matter if there are problems. The important thing is that we can find problems in time and find solutions to them. .

Abnormal noise in car driving is one of the most common fault phenomena. It may be caused by a screw that we accidentally dropped somewhere, some parts are loose or lack of lubrication, and some parts are deformed and damaged. For this kind of fault, we first need to judge the approximate direction through the abnormal sound source, and then find the location according to the direction.

What's wrong with many fault lights on the dashboard

When this warning light is on, it means that the car door or trunk door is not closed, especially when there are elderly and children in the car. Remember to make sure that the car The door is safe, and don't leave any safety hazards.

The quality of automobile fuel is not qualified. If the engine fault light on the dashboard of the car lights up shortly after the vehicle is refueled, then it is generally due to the wrong oil addition, poor quality, and non-standard, resulting in insufficient combustion of oil-gas mixture when the engine is working.

The reason why the dashboard lights of the car are all on: 1. The CAN bus of the electronic control unit fails, and the CAN interface of the electronic control unit has poor contact.There is too much dirt and carbon accumulation, and the empty air circulation is abnormal, and the normal air intake cannot be accurately controlled, resulting in unstable gas content and the engine not working well.

The reason why the car dashboard light is fully lit: the CAN bus failure of the ECU, and the CAN interface of the ECU has poor contact. Too much dirt and carbon accumulation, abnormal air circulation, and the normal air intake cannot be accurately controlled, resulting in unstable gas content and the engine not working well.

What do these fault lights of the car mean? There are many headlights, button prompts, etc. on the car. We don't know much about the others, but it is still necessary to know the meaning of these fault lights on the dashboard. Let's take a look together.

Sensor problem: The sensors mentioned here include water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc.When these sensors are damaged, have poor contact, or the signal is interrupted, and the ECU of the car cannot accurately obtain the engine data, it will cause the engine failure light to light up. Solution: Go to the 4S store to repair or replace.

What is the sign of car failure

Tire pressure warning light: yellow sign, irregular round, no seal at the top, four small spikes at the bottom, and an exclamation mark inside. The appearance of this sign indicates that the tire pressure of the car is abnormal, and the tire needs to be checked in time. Transmission system warning light: a yellow gear with an exclamation mark inside.

Car fault light signs include: oil alarm light, engine fault alarm light, water temperature alarm light, brake system fault light, tire pressure alarm light, battery alarm light, steering assistance system fault light, electronic body stability system indicator light and abs anti-lock system indicator light.

Common fault signs of automobiles: Battery indicator light: a symbol like a battery, with a minus sign "-" in the upper left corner and a plus sign "+" in the upper right corner. Under normal circumstances, the vehicle should be turned on during self-inspection and turned off after starting. If the battery indicator light is always on after starting, it means that there is a problem with the battery.

A yellow gear with an exclamation mark in it is a warning sign for the transmission system; a circle with a P and an exclamation mark inside is an electronic parking problem sign; a kettle with a drop of water at the mouth of the kettle is an oil pressure alarm sign.

Eight signs of car breakdown

1. The situation suddenly changes. For example, it is difficult to start after the engine suddenly turns off, or even It can be started; the engine's power suddenly decreases while driving, and it is weak to drive; the brakes suddenly fail or run sideways while driving, or even fail, etc. Abnormal noise The abnormal sound of the car during driving is the "alarm" of the car fault.
