Air filter: The role is to filter the dust and impurities in the air, so that the clean air into the engine, which is important for the engine's life and normal work. Air filters absorb more dust and contaminants, which can affect engine work and must be replaced on a regular basis. If driving in dusty places, such as dust storms, the cycle of replacing air filters will also be shortened.
Battery: Needless to say, it is storage of electricity. Lead batteries are generally used, and the electrolyte is dilute sulfuric acid.
Brake fluid: The brake oil is usually said. Nowadays, the brakes of cars are generally hydraulic, that is, brake fluid is used as a medium to transmit the force of the brake pedal to the brake disc.
Ignition coil: The low voltage is converted to a high voltage, and the spark discharge underneath it produces an electric spark, which ignites the oil and gas mixture to burn and do work.
Oil: This also does not have to say, as a mineral oil or synthetic oil that acts as a lubricant seal. If the engine lacks the lubrication of the oil, it will cause serious problems such as pulling cylinders and holding tiles.
Power steering oil: Nowadays, the power steering assistance of a car is usually a traditional hydraulic boost. Since it is the corresponding hydraulic pressure, it needs an oil medium. Of course, some cars have begun to use electric power, which is also the future development trend.
Antifreeze: The passage in the radiator and engine block circulation, the liquid medium used to cool the engine, mainly water and additives, because of the antifreeze function, called antifreeze.
Glass Water: Everyone on the planet knows what to use for glass.
Dipstick: A ruler for checking the amount of oil. When the engine is turned off, pull out the oil dipstick, clean the upper oil with a clean paper towel, and then insert and pull it again. The oil level of the oil must be between the two upper and lower limits on the ruler. No less.
Fuse box: There are many fuses for electrical equipment and relays. There are two fuse boxes for the small F and the other one is at the lower left of the cab driver. Specific to see the car instructions.
A vehicle that can't be found in every possible way, doing all the maintenance and repair on the WeChat public platform
Air inlet: The inlet of the engine intake. This is optimized. The position has been improved a lot. The inlet position of the older vehicle is relatively low, and the engine is easy to enter the water when wading. The position of the air intake is the limit of the wading depth of the car and must not be exceeded. Once the engine water, the consequences are very serious ~!
Electronic Throttle: It is said that the throttle, in fact, has nothing to do with the oil, it is connected to the intake manifold and intake manifold, the control of the engine intake air, so the correct argument should be electronic throttle. The engine control module calculates the fuel injection quantity based on the intake air quantity, so that the engine speed and output power can be controlled. There is also a pull throttle, which uses a cable to control the throttle opening. Although the power is not directly lagging behind the electronic throttle, the electronic throttle technology is high and fuel-efficient.
Intake manifold: Intake manifold branched from the intake manifold to each cylinder. Although it is a pipe, it can be a technological know-how, such as a variable intake manifold.
Carbon canister valve: Carbon canister absorbs the gasoline vapor in the fuel tank. After the canister valve is opened, the engine will suck the gasoline vapor absorbed by the activated carbon in the canister into the intake pipe and finally participate in the combustion. This will not only benefit the environment but also save some oil.
Gasoline Dispenser: Gasoline is distributed to each fuel injector. Underneath it is the injector, which is blocked from view.
Specific details: In the engine work, there is always a part of the combustible mixture and exhaust gas through the piston ring into the crankcase, picking up the gasoline vapor in the crankcase will condense the engine oil thinning, performance deterioration. Exhaust gas contains water vapor and sulfur dioxide. The water vapor condenses in the engine oil to form bubbles and destroys the oil supply. This phenomenon is particularly serious in winter. Sulphur dioxide reacts with water to generate sulfurous acid, and sulfurous acid encounters oxygen in the air to generate sulfuric acid. These acidic substances The appearance of the engine not only deteriorates the engine oil but also causes the parts to be corroded. As the combustible mixture and exhaust gas are dumped into the crankcase, the pressure in the crankcase will increase and the oil will leak from the crankshaft oil seal, the crankcase liner, etc., and be lost. The loss of engine oil vapor to the atmosphere will increase the engine's pollution to the atmosphere. The engine is equipped with a crankcase ventilation device to avoid or reduce the above phenomenon. Therefore, the function of the engine crankcase ventilation device is: 1. To prevent oil deterioration: 2. To prevent the crankshaft oil seal, crankcase liner leakage; 3. To prevent various Oil vapor pollutes the atmosphere. Crankcase ventilation includes natural ventilation and forced ventilation. Modern gasoline engines often employ forced crankcase ventilation, also known as PCV systems. When the engine is working, the intake manifold vacuum draws fresh air through the air filter and air hose into the cylinder head cover, and then enters the crankcase through the cylinder head and the hole in the body. In the crankcase, fresh air and crankcase gas are mixed and passed through the cylinder head cover and the crankcase gas hose into the intake pipe, and finally burned through the intake valve into the combustion chamber.
Injector: The gasoline pumped by the petrol pump is atomized. The nozzle hole is very small, so as to better atomize the gas, but it is also very easy to plug, so regular cleaning of the nozzle. Now the car's engine is generally EFI's, the so-called EFI is the abbreviation of electronically controlled fuel injection. The basic principle is that the engine control module calculates the optimal injection timing and fuel injection amount according to the information of each sensor, controls the fuel injector, injects the gasoline into the end of the intake manifold, and then is sucked into the cylinder by the engine and burns to do work. Unlike traditional carburettor engines, the EFI engine can control the amount of fuel more precisely. It is well atomized and burns well. The result is excellent performance. My spatial data is updated every day, and it can save fuel. However, the advanced technology is also short-circuited, too complicated, and maintenance may not be easy.
Vacuum booster: The use of the force generated by the difference between the vacuum pressure of the engine intake pipe and the pressure difference of the atmospheric pressure to assist the brake can reduce the "labor intensity" of the driver. After the engine is turned off, you can step on the brakes a bit and you will step on the booster. Then step on the brakes, and you will find that you will not be able to step on your breasts. Without help, driving is really physical labor! This is why the engine must not turn off when the car is running. Once the flame is turned off, the booster is gone and the brakes fail. At the same time, the hydraulic power steering also fails. Think about it.
Master cylinder: The brake fluid pressure is generated and transmitted to each brake cylinder via the brake pipe.
Clutch master cylinder: When the clutch pedal is depressed, the clutch master pump connected to the pedal will act, generate hydraulic pressure, transfer it along the pipeline to the clutch pump, and finally convert it into a mechanical force separation clutch. F's clutch operating system is hydraulic and shares a hydraulic fluid with the brake system, so there is a tube connected to the brake fluid tank.
ABS pump: very important safety device 噢~! ABS means automatic anti-lock braking system. When the brakes are applied, the ABS system will automatically apply tens of brakes per second to each wheel according to the information such as the vehicle speed and the braking force to prevent the tires from slipping and losing control. And can provide steering ability when braking, to avoid obstacles.
Steering booster pump: Provides hydraulic power for steering assistance. Recently, some owners of the jars reflected the problem of abnormal sound of the belt, which was to offset the displacement of the pump support. As a result, the pulley of the booster pump was not on the same plane as the other pulleys, and the pulleys did not normally rub against the pulleys, causing noise.
Air Conditioning Compressor: The vaporized refrigerant is compressed into a liquid and then pumped into the evaporator to produce the cool we need!
Exhaust manifold: The exhaust gas produced by each cylinder of the engine is discharged into the exhaust manifold through the exhaust manifold, and then exhausted to the atmosphere through a three-way catalytic converter and a muffler. Because the exhaust of the engine is very hot, a protective shell is added here to provide insulation. Seeing that the hand sign is not there, there is an X, which means don't touch it.
Oxygen sensor: detects the oxygen content in the exhaust gas and sends the signal to the engine control module to control the fuel injection amount so that the fuel can be fully burned and the emission can be reduced.
