What are the contents of the daily maintenance operations of the car

The daily maintenance work is mainly based on the "three inspections" of the vehicle (i.e., inspection before leaving the vehicle, during driving, and after receiving the vehicle; The safety mechanism of the vehicle and the fastening of the connection of various parts, fill the lubricating oil and fuel after returning to the field, and pay attention to all parts of the vehicle at any time during operation.

Operation. If the fault is found to be eliminated or repaired in time, drive without illness), keep the vehicle "four clean" (oil, air, and fuel filtration.

The cleaning of the device and the battery) prevents the vehicle from "four leaks" (leakage of oil, water, electricity, gas), and makes the car look clean and tidy.

The daily maintenance of the car includes the following:

1. Clean the appearance of the car and the engine to keep the car clean and tidy;

2. Check and replenish lubricating oil (grease), fuel, coolant, brake fluid, various working mediums and tire pressure of various parts of the automobile;

3. Check the safety parts and positions of the car such as braking, steering, transmission, suspension, lights, signals, etc., as well as the engine running status

Calibrate tightly to ensure the safety of the trip.

Routine maintenance can be done by the driver.

Hopefully so, thank you.

1. Maintenance of the car.

2. Replacement and maintenance of car parts.

3. Sheet metal painting of automobiles.

Vehicle maintenance operations include inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle.

The purpose is to keep the car clean and tidy, the technical condition is normal, eliminate hidden dangers, prevent failures, slow down the deterioration process, and prolong the service life. Automobile maintenance is based on the law of the change of automobile technical conditions with mileage, and stipulates the content of different levels of operation items.

According to the regulations of the Ministry of Communications, China's current automobile maintenance system is divided into daily maintenance, first-class maintenance, second-level maintenance, etc. In addition, there is seasonal maintenance and walk-in maintenance.

It is stipulated that the maintenance operation content of the vehicle is: cleaning, inspection, replenishment, lubrication, fastening, adjustment, etc., except when the main assembly fails and must be disassembled, the vehicle shall not be dismantled at will.

Daily inspections are: 1. Brake and brake oil level. 2. Oil level. 3 water tanks. 4. Battery connector. 5. Tire pressure. 6. Front and rear lights, etc.

Figure 1-4 Preparation for vehicle maintenance.

Dress up. 2.Vehicle protection. 3.Lifting equipment. 4.Measuring instruments. 6.Tool.

1) Dress. When repairing a car, be sure to wear clean work clothes, a work cap, and safety shoes.

2) Vehicle protection.

Before servicing, prepare radiator grille covers, fender covers, seat covers, floor mats, steering wheel covers, gear lever covers, etc.

3) Safe operation of lifting equipment.

When two or more people are working together, it is essential to check each other's safety. When working with the engine running, the workshop should be ventilated to exhaust the exhaust gases. When repairing parts that are subject to high temperatures, high pressures, rotation, movement, or vibration, be sure to wear safety gear and be careful not to injure yourself or others.

When lifting the vehicle, make sure to use a safety base to support the designated position. When lifting the vehicle, use safety equipment.

4) Prepare tools and measuring instruments.

Prepare tool holders, tools, special tools, instrumentation, consumables, and replacement parts before the job.

5) Disassembly and installation, disassembly and assembly operations.

Before disassembling parts, check the general condition of the assembly to confirm whether it is deformed or damaged. For complex components, keep a good record. For example, record the total number of electrical connections, bolts, or hoses removed and mark the assembly to ensure that all parts are installed in their original locations when they are reassembled.

If necessary, hoses and fittings can be temporarily marked. If necessary, clean the removed parts and assemble them after a thorough inspection.

6) Handling of disassembled parts.

Removed parts should be placed in a separate box to avoid confusion or staining with new parts. For non-reusable parts (such as washers, O-rings, and self-locking nuts), replace the parts with new ones according to the instructions in the manual.

1. Regular maintenance.

Periodic maintenance is the maintenance of the car carried out according to the operating interval specified in the technical documentation, and is carried out in a specified cycle throughout the life cycle of the car. According to the automobile maintenance system in the "Regulations on the Technical Management of Vehicles in the Automobile Transport Industry" (hereinafter referred to as the "Regulations"), automobile maintenance is divided into: routine maintenance, first-level maintenance and second-level maintenance.

The cycle and main business contents of maintenance at all levels are:

1. Routine maintenance.

Routine maintenance (daily maintenance): It is a daily operation, which is carried out by the driver before leaving the car or after receiving the car, and the center capacity is cleaning, replenishment and safety inspection.

2. First-level maintenance.

It is carried out by professional maintenance workers in the repair workshop or repair shop. The interval mileage period is generally 1000 2000km. In addition to daily maintenance work, the core content of its operation is mainly inspection, lubrication, and firmness, and the inspection of components related to braking, steering and other safety systems.

3. Secondary maintenance.

It is carried out by professional maintenance workers in a maintenance workshop or in a professional maintenance workshop. The interval mileage is generally 10000 15000km. In addition to the first-level maintenance operation, the content of the operation center is mainly based on inspection and adjustment, and the tires are dismantled and inspected, and the tires are transposed.

2. Seasonal maintenance.

The maintenance that is performed to adapt the car to the changing seasons is known as seasonal maintenance. General seasonal maintenance can be carried out in conjunction with regular maintenance. The main tasks are to change the lubricating oil, adjust the oil circuit, and check and maintain the cooling system.

3. Walking and closing maintenance.

Walk-in maintenance refers to the maintenance carried out during the walk-up period of a new car or overhauled vehicle. In addition to paying special attention to routine protection, the main operation content should be frequently inspected and tightened with exposed bolts and nuts, and the sound and temperature changes of each assembly in operation should be paid attention to, and appropriate adjustments should be made in time. At the expiration of the closing period, the lubricating oil should be replaced in each assembly, and attention should be paid to cleaning, the connecting parts should be tightened, and the gap between each part should be adjusted.

The category of automobile repair is divided according to the repair object and the depth of work. According to the repair object and the depth of operation, it is divided into: automobile overhaul, assembly repair, automobile minor repair and parts repair.

Automobile overhaul: A restorative repair that restores the car's intact technical condition or completely (or nearly completely) restores the life of the car by repairing or replacing any part of the car, including the basic parts. Automobile overhaul is the dismantling of the whole vehicle and the inspection, repair or replacement of all parts.

The term of automobile overhaul is very different with the quality of automobile products, the use of conditions and the usual maintenance status, the vehicle technical management department should be close to the overhaul quota mileage of the vehicle to strengthen the status monitoring, combined with maintenance for regular testing, do a good job of technical appraisal work, according to the overhaul of the car repair conditions in a timely manner.

Assembly repair: It is an operation to restore the intact technical condition, working capacity and life of an assembly of the car. That is, after a certain period of service, the basic parts and main parts of the assembly are broken, worn, aging, etc., and need to be disassembled for thorough repair to restore its technical condition.

The main assemblies include engine, frame, body, transmission, rear axle, front axle, etc. Technical appraisal should be carried out before sending for repair, and if the conditions for repair are met, it should be sent for repair according to the regulations.

Automobile minor repair: It is an operational repair that uses the method of repairing and replacing individual parts to ensure or restore the working ability of the vehicle. It is mainly to eliminate the faults and hidden dangers that occur or are found during the operation of the vehicle and in the maintenance operation.

Parts repair: It is to repair parts that cannot be used due to wear, deformation, damage, etc., in order to restore their performance and life. It is an important measure to save raw materials and reduce maintenance costs.

Of course, the repair of parts must take into account whether there is repair value and the principle of economy.

Repair according to the situation: refers to the repair that determines the content and implementation time of the repair after diagnosing or testing the technical condition of the automobile according to the provisions of the technical documents. That is, the level and item of repair are determined according to the appraisal results.

Do you have any questions?

No, thank you.

Dear: It's okay.

Daily maintenance is mainly cleaning, security check, refueling, etc. The slightest negligence will not only cause unnecessary damage to the vehicle, but also endanger driving safety; On the contrary, careful, careful and solid daily maintenance can not only make the car "forever young", but also master the technical condition of all parts of the vehicle and avoid various mechanical accidents and traffic accidents.

Before leaving the car, check the surroundings of the car, whether the lighting devices are damaged, whether the body is tilted, whether there is oil leakage, water leakage and other leakage, check the appearance of tires, and the condition of the door, engine compartment cover, luggage compartment cover, and glass.

If there is oil or dripping oil under the car, it is necessary to find out its ** and eliminate the fault in time. If the tire pressure is low, check the tire for "bulging" and air leakage in time;

If the shoulder is damaged or bruised, the tire should be replaced in time to prevent a puncture. Turn on the ignition key (note: do not start the engine) and check the lighting of all warning lights and indicator lights; Start the engine and check that all warning lights are out normally; See if the indicator light is on normally; Check the fuel gauge for instructions and refill fuel if necessary.

It boils down to this: five oils and three waters.

Five oils: engine oil, transmission oil, brake fluid, power steering oil, gasoline and diesel. Three waters: tank water, wiper water, battery water (maintenance-free batteries can only be observed through the color of the holes)].

Automobile maintenance is a very complex professional skill, and professional automobile maintenance workers need to know a lot of knowledge, such as automobile circuits, automobile engine working principles, automobile transmission working principles, etc.

Before mastering the knowledge of car maintenance, it is necessary to have a detailed understanding of the car. The car is mainly composed of the body, engine, gearbox, chassis. Then the body is divided into body frame and body covering.

Body panels include front and rear bumpers, front fenders, front bonnets, trunk lids, and doors. Since the roof and rear fenders are welded to the body frame, the roof and rear fenders are considered structural parts of the body.

Today's cars are using load-bearing bodies, and the body and girders are integrated, so the body is lighter, more comfortable, and can better disperse the force of the collision in the event of a collision to protect the safety of the occupants of the car.

The chassis parts of the load-bearing body are directly fixed on the body, and the load-bearing body has a subframe, so the subframe is to strengthen the rigidity of the body, and the subframe also carries some key components.

The engine transmission and front suspension of front-engine front-wheel drive cars are fixed to the front subframe, and the engine and front suspension of front-engine rear-wheel drive vehicles are fixed to the front subframe, and the rear subframe is fixed to the rear differential and rear suspension.

The subframe plays a very important role in the chassis, and the subframe also transmits the force of the collision in the event of a collision.

There are many types of transmissions in automobiles, and transmissions are divided into CVT transmissions, dual-clutch transmissions, AMT transmissions, AT transmissions, manual transmissions, etc., and the working principle and breakdowns that are prone to occur are different for each type of transmission.

It is also very important to be able to understand the circuit diagram of the car, the automotive circuit is the most difficult professional knowledge to master, and understanding the car circuit can determine the fault location faster and more accurately. Nowadays, there are many auto mechanics who can't understand the circuit of the car, so this kind of auto mechanic is guessing the fault when repairing the car.

Before learning about car maintenance, you need to have a detailed understanding of the car, and have a good understanding of the role of each part of the car, and it is best to know what the failure of each component is prone to. Hope to adopt.
