20 10 Sonata Automatic Transmission Engine Room Component Location Name

1, air filter: its function is to filter dust and impurities in the air and let clean air enter the engine, which is very important for the life and normal work of the engine. If the air filter absorbs too much dust and impurities, it will jam and affect the engine work, so it must be replaced regularly. If you drive in dusty places, such as places with sandstorms, the cycle of replacing air filters will be shortened.

2. Battery: Needless to say, it stores electric energy.

3, brake fluid: it is the usual brake oil. At present, automobile braking is generally hydraulic, that is, brake fluid is used as the medium to transfer the force of the brake pedal to the brake disc.

4. Ignition coil: low voltage is converted into high voltage, and the spark plug below it generates sparks to ignite the oil-gas mixture to do work.

5. Engine oil: Needless to say, it is mineral oil or synthetic oil that plays the role of lubrication and sealing. If the engine lacks oil lubrication, it will cause serious problems such as cylinder pulling and bearing bush.

6. Power-assisted steering oil: At present, the steering power of automobiles is generally traditional hydraulic power. Since it is hydraulic, it needs oil medium. Of course, some cars have begun to use electricity, which is also the future development trend.

7. Antifreeze: The liquid medium circulating in the radiator and engine cylinder, mainly water and additives, is called antifreeze because of its antifreeze function.

8. Glass water: Everyone knows that it is used to clean glass.

9. dipstick: a ruler for measuring oil quantity. When using, first turn off the engine, pull out the dipstick and use a clean paper towel.

Wipe off the oil, then plug it in and pull it out. Look at the oil level. It must be between the upper and lower scales on the ruler, neither more nor less.

10, fuse box: There are many fuses for electrical equipment and relays. Little F * * * has two safety boxes, and the other one is on the lower left of the cab driver. Please refer to the on-board instructions for details.

1 1, air intake: the inlet of the engine air intake. This is optimized, and the position has been improved a lot. The air intake position of the old car is relatively low, and the engine is easy to get water when wading. The position of the air inlet is the limit of the wading depth of the car, which must not be exceeded. Once the engine is flooded, the consequences will be very serious.

12, electronic throttle: it is a throttle, but it has nothing to do with oil. Oh, it is connected with the intake manifold and controls the intake volume of the engine, so the correct term should be electronic throttle. The engine control module will calculate the fuel injection quantity according to the air intake, thus controlling the engine speed and output power.

13. intake manifold: the intake manifold branches from the intake manifold to each cylinder. Although it is only a pipe, it is high-tech, such as variable intake manifold.

14. canister valve: the canister absorbs gasoline vapor in the fuel tank. After the canister valve is opened, the engine will suck the gasoline vapor adsorbed by the activated carbon in the canister into the intake pipe and eventually participate in combustion. This is not only beneficial to environmental protection, but also saves a little oil.

15. gasoline distributor: gasoline is distributed to all fuel nozzles, which are connected below it and are blocked from view.

16. Crankcase ventilation pipe: the right intake pipe and the left exhaust pipe are used for crankcase ventilation.
