What parts are there in the engine compartment? A preliminary understanding of each component.

1, open the hood of the car first, and look at the water inlet of this wiper first. This is the wiper water that we can fill ourselves at ordinary times, and it is the clean water sprayed on the front windshield. Whenever we run out, we can go to the supermarket to buy finished glass water or make it ourselves. Just open the lid and you can fill it up. Remember the sign above.

2. Power steering oil is a new technology to improve automobile comfort, which can automatically provide steering force when the driver turns, thus reducing the steering labor intensity of the driver. Power steering oil is a medium oil filled in the power steering system, which plays the role of transmitting steering force and buffering.

3. Coolant is used to cool the engine to a constant temperature. Automobile engines are divided into large cycle and small cycle, both of which are engines cooled and heated by coolant in pipelines. It also has the advantages of rust prevention, antifreeze and water resistance. This rehydration tank is used to supplement the lack of coolant. When the coolant in this tank drops to the lowest level, it should be replenished in time.

Needless to say, the battery is one of the most important parts of the car, without which the car can't be started. Once the battery is lost or dead, the car starter will not work, which means it can't be started. At the same time, it also indirectly supplies some electrical appliances with normal circuits, such as small lights, reading lights, speakers and so on. It needs to be replaced in time after a certain number of years.

5. The air filter element is equally important. Without the filtering function of the air filter, the engine will inhale a lot of air containing dust and particles, resulting in serious wear of the engine cylinder; On the other hand, if it is not maintained for a long time during use, the filter element of the air filter will be covered with dust in the air, which will not only reduce the filtering ability, but also hinder the circulation of air, resulting in too much mixed gas and abnormal engine operation. The fuse box is the protection device of the electric circuit, which is convenient to judge the problem when the circuit fails, and it is the hub station of the circuit.

6. The brake fluid is increased by the main brake pump through the liquid pressure, so that the pistons on the sub-cylinders on the four wheels are pushed out by the sealing cups, and the brake discs and brake pads are braked by the lever principle. Replace the brake fluid after 2 years or 50,000 kilometers.

7. The automatic transmission dipstick is used to check the automatic transmission oil. The transmission oil is changed every 2 years or 60,000 kilometers, which means that the vehicle has been used for more than 2 years, but it has only traveled more than 20,000 kilometers; Or the vehicle is only used less than 1 year, and the mileage reaches 60,000 kilometers. In both cases, the gearbox oil should be changed.

8. The oil filler is undoubtedly used to add oil. When maintaining, you need to open the oil filler. The dipstick is used to check the oil level. The generator is used to send electricity to the vehicle electrical appliances and charge the battery when the car starts. Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned. It is connected with the air filter, and the engine cylinder is the throat of the automobile engine. The throttle needs to be cleaned regularly, because driving for a long time will produce a lot of carbon deposits in the throttle, which will hinder the normal circulation of air, thus making it difficult for the owner to start the car.
