Novices pay special attention to car maintenance four do not

1. Because the preservatives used in different brands of coolants are different, they cannot be mixed. When starting, pay attention not to step on the accelerator when starting the electric injection vehicle. It is the habit of many old drivers to step on the accelerator a few times before starting the engine, especially when the car is cold in winter. However, this start-up method is not suitable for electric injection cars.

2. Do not step on the accelerator when the electric injection car starts. The engine of the electric injection car is different from that of the ordinary car. Its fuel injection control device can automatically adjust the fuel supply according to the temperature and working conditions of the engine, so that the engine can start smoothly. In cold weather, most car owners will step on the accelerator a few times before starting the engine, but this method is not suitable for electric injection cars.

3. Pay attention to car maintenance and avoid fires. When maintaining cars, you often need to use flammable and explosive items such as oil and cleaning agents. At this time, don't forget to take fire prevention measures and prepare fire extinguishers just in case. Special attention should be paid to not smoking near flammable and explosive items such as fuel tanks and batteries to avoid explosions.

4. Specifically, it can be replaced according to the maintenance manual of the car.

5. Routine maintenance does not need to be changed. There are indeed many money-saving tricks for maintenance in the 4s store. The webmaster of a maintenance station told the reporter that routine maintenance actually has a way for car owners to save money.

What does the four-wheeler of automobile maintenance mean?

The four-in-one automobile maintenance refers to the centralized detection line, which is composed of a single-board side slip test bench, a suspension device, a test bench and a brake test bench, which can centrally detect side slip, suspension, axle weight and braking performance. Nowadays, automobile maintenance covers engine, gearbox, chassis, cooling system, fuel system and other maintenance fields.

The passage is smooth and tidy. The equipment and materials in the workplace should be neatly stacked and unnecessary things should not be placed.The office items on the desk and in the drawer are neatly classified and placed. The items on the material rack are neatly arranged. Rectification: The machinery and equipment are regularly maintained and there are equipment maintenance cards, which are neatly arranged and in the best condition.

Automotive engine four accessories refer to the cylinder liner piston piston ring size connecting rod shaft tile four accessories are also known as four supporting components cylinder liner repair package cylinder liner piston components, etc. They are the motion components of the engine, which cooperate with the fuel system and gas distribution mechanism to complete the engine intake compression combustion work and exhaust stroke, and chemical Can be converted into.

Three inspections a day; inspection before leaving the car, inspection in the middle of departure, and inspection after receiving the car. The four clears are; engine oil clear, brake fluid clear, direction oil clear, and antifreeze liquid clear. Clear generally means that the liquid has not deteriorated, four no leakage; no leakage of electricity, no air leakage (air brake), no oil leakage. No water leakage (antifreeze).

Keywords: automobile maintenance, current situation, development countermeasures Introduction Automobile maintenance is a general term for automobile maintenance and repair. Automobile maintenance is an operation carried out to maintain the intact technical condition or working capacity of the automobile, mainly to inspect, clean, lubricate, tighten, adjust or replace certain parts of the automobile.

Therefore, in automobile maintenance, it is not only necessary to ensure that the timing marks are fully aligned, but also to carefully check the actual opening and closing moment of the intake valve and exhaust valve, and whether the gas distribution phase has deviated due to the wear or deformation of the relevant parts. It can be seen from the structural principle of the engine, starting from the crankshaft timing gear.

4 steps of car maintenance method

1. Specific process steps of car maintenance: check the engine oil level.When driving on a flat road, this is normal if the oil level is within the marking range of (f) and (l). If it is lower than (l), the specified type of engine oil should be added, and the filling level should not be higher than (f). Maintenance and inspection of the battery.

2. Step by step. This method is to use the knowledge learned and various testing equipment to find faults step by step. This method is often used in some soft faults and difficult problems. First, check the ignition system, replace the spark plug, and measure the high-voltage line to meet the standard value. Clean the gasoline filter and test whether the oil pump pressure is normal.

3. Maintenance personnel's inspection of the car is the first step after receiving the car, and it is also a very important step. The customer's description is verified by the actual car, and the preliminary inspection and diagnosis are carried out to ensure the accuracy and scientificity of the order.

4. It is easy to heat and burn. It costs hundreds of yuan to replace a fuel pump. Using this method to control the use of oil is really a small loss. Regarding the maintenance methods of cars, all drivers should still learn a little to avoid the embarrassment of encountering small problems when driving out and there is no way to solve them. At the same time, the maintenance of cars cannot be ignored.

5. For car owners, they are most afraid of the repair of cars, especially second-hand cars, which cost more than a thousand yuan per minute. If it involves replacing parts, it costs more money. Regular oil change. The most basic regular maintenance of the car is to change the oil regularly, which can lubricate and protect the engine to ensure its normal operation.

6. Maintenance quotation: According to the test results, the clerk will quote the maintenance work that needs to be carried out and inform the car owner.Maintenance work: After the owner agrees to the quotation, the technician begins to carry out the maintenance work. Maintenance acceptance: After the maintenance work is completed, the owner will inspect the car and confirm the quality of the work.

4 kinds of wasteful behaviors in car maintenance

The fourth kind of waste: too much oil. When the engine is working, the crankshaft handle and the large end of the connecting rod will produce violent stirring, which increases the internal power loss of the engine, and also increases the oil splashed on the cylinder wall, resulting in oil burning failure. It is better to control the oil in the engine oil sup shell between the upper and lower engraving lines of the oil scale.

The first kind of waste: maintenance is too "diligent". Miss Zhao is a car blind person. She often receives maintenance letters from dealers.The new car has only driven 8,000 kilometers. Miss Zhao's engine oil has been changed 3 times, and the engine filter has also been changed 3 times. The maintenance interval mileage is less than 3,000 kilometers.

The first wasteful behavior: too frequent maintenance. Many car owners do not know the maintenance cycle of the car, but they are often prompted by the maintenance information sent by the car dealer, so they have changed the oil three or four times after buying a new car for less than a year. The most important thing is that the interval cycle and time of each oil change are very short.

The fourth kind of wasteful behavior: In normal use, cars that can only drive but can't maintain cars pay attention to three-point repair and seven-point maintenance. If our car owner can only drive but does not maintain the car, then there will be a contrast between maintenance and non-maintenance.

Scientifically determining the interval mileage of various maintenance operations can keep the car in good technical condition, and also save maintenance and repair costs.
