Air filter: the function is to filter the dust and impurities in the air, so that clean air into the engine, which on the engineLife and work are important. Air filter adsorption of dust, impurities will clog up, affecting the engine work, so must be fixedReplacement period. If you drive in a dusty place, such as a dust storm, the cycle of changing air filters will be shortened.
Battery: Needless to say, is to store electrical energy. Usually lead-acid batteries, electrolyte is dilute sulfuric acid.
Brake fluid: as usual, brake fluid. Now the brakes of the car are generally hydraulic, that is, the brake fluid as the medium will brakeThe force of the pedal is passed to the brake disc.
Ignition coil: convert a low voltage to a high voltage, discharge an electric spark through the spark plug below it, and ignite the gas mixtureCombustion work.
This is not to say, the oil lubrication sealing effect of mineral oil or synthetic oil. If the lack of engine oil lubrication will produce cylinder, holding tile and other serious problems。
Power steering oil: now the general direction of the car steering or traditional hydraulic power, since it is hydraulic, the corresponding need oil medium. Of course, some cars have begun to use electric power, and this is also the future trends。
Antifreeze: a channel in a radiator and an engine cylinder that is used to cool the engine's liquid medium, mainly waterAnd additives, because of the antifreeze function, called antifreeze.
Glass water: Earth people know, use glass cleaning.
Oil dipstick: a ruler for measuring the amount of oil. For the first time the engine flameout, pull out the dipstick, with a clean towelClean the top oil, then plug in and then pull out. Look at the oil level of the oil. It must be between the two upper and lower scales on the ruler,No more, no less。
Fuse box: there are a lot of fuses and relays in the electrical equipment. Little F has two safety boxes altogether, another below the driver's cab. Look at the following instructions.
Intake: intake of the engine intake, this is optimized, the position has increased a lot, the old car intake positionThe installation is relatively low, easy to enter the water when wading. The position of the air intake is the limit of the depth of the vehicle wading. Once the engine enters the water, the consequences are serious ~!
Electronic throttle: that is the throttle, and in fact there is nothing to do with the oil, oh, it is connected to the intake manifold and intake manifold，The engine intake is controlled, so the correct statement should be the electronic throttle. The engine control module will be based on the intake meterCalculate the fuel injection, so that you can control the engine speed and output power. There is a guy with a throttle cable to
control throttle opening, although the power is not directly without the electronic throttle lag, but the electronic throttle technology is high, and fuel-efficient.
Intake manifold: from intake manifold to intake of each cylinder. Although it is a tube, there is a technology, including
Carbon canister valve: gasoline vapor adsorption carbon canister in the tank, the canister valve is opened, the engine will be carbon tank of activated carbon adsorption of gasoline vapor inhalation intake pipe, finally in combustion. This is not only conducive to environmental protection, but also save a little oil.
Gasoline distributor: the gasoline is distributed to each injector, and the fuel injector is connected below it. It is blocked. Look at missing.
Crankcase ventilation pipe: on the right is the intake pipe, the left is the exhaust pipe, the role is to crankcase ventilation.
Specific details: when the engine works, there is always a part of combustible mixture and exhaust gas through the piston ring into the crankcase，The gasoline vapors that run into the crankcase will dilute the oil and deteriorate the performance. Exhaust gas contains water vapor and sulfur dioxide，Water vapor condenses in the engine oil to form foam, which destroys the oil supply. This phenomenon is especially serious in winter. Sulfur dioxide generates sulfurous acid in water,Sulfurous acid produces sulfuric acid when oxygen is encountered in the air. The presence of these acids not only causes the oil to deteriorate,It also causes the parts to corrode. The pressure in the crankcase will increase as the mixture of combustible gas and exhaust gas break into the crankcase,The oil will leak out of the crankshaft oil seal, crankcase gasket, etc.. The loss of oil vapor into the atmosphere increases the engine's pollution of the atmosphere.The engine is equipped with crankcase ventilation to avoid or mitigate the above phenomenon,
Therefore, the function of the engine crankcase ventilation is：
1., prevent oil deterioration: 2. to prevent the crankshaft oil seal, crankcase gasket leakage; 3., to prevent all kinds of oil vapor pollution of the atmosphere
. Crankcase ventilation includes natural ventilation and forced ventilation. Modern gasoline engines often use forced crankcase ventilation, also known as the PCV system. When the engine is working, the vacuum of the intake pipe attracts fresh air through the air filter and air hose into the cylinder head cover, and then enters the crankcase from the cylinder cover and the hole on the machine block. In the crankcase, the fresh air is mixed with crankcase gas
The cylinder head cover and crankcase gas hose enter the intake pipe and finally enter the combustion chamber through the intake valve.
Fuel injection nozzle: the gasoline which is pressed by the gasoline pump is ejected in the form of atomization. The orifice of the injector is very small, so that it can better atomizing gasoline, but it is also easy to plug, so it is necessary to clean the nozzle regularly. Now the car's engines are generally EFI, the so-called EFI is electronically controlled fuel injection referred to as. The basic principle is that the engine control module is based on individual sensors
It calculates the best injection timing and fuel injection quantity, controls the fuel injector, and the gasoline is injected to the end of the intake manifold. Then the engine is sucked into the cylinder to do combustion work. Unlike conventional carburetor engines, EFI Engines are more accurate
The amount of fuel produced, atomized, and burned sufficiently is excellent performance and fuel saving. However, the advanced technology is also short board, too complex, and maintenance is not easy.
Vacuum booster: by using the force of the vacuum negative pressure of the air intake pipe of the engine and the pressure difference of the atmospheric pressure to assist the brake, the working intensity of the driver can be reduced". After the engine flameout, you can first step on a few feet brake, will help step on it. And then step on the brakes, you will find the use of milk can not step on how much. Without help, driving is really manual work
~ that's why the engine must not stall in the car. Once the flameout, the power will be gone, the brakes will fail, and hydraulic power steering failure, and think about it, can not hit the direction, can not brake the car, how terrible ~!
Brake master cylinder: produces brake fluid pressure through the brake tubing to each brake pump.
Clutch master pump: when the clutch pedal is pressed, the clutch master pump acting on the pedal will act to produce fluid pressure, which is transmitted along the pipe to the clutch pump and finally converted to a mechanical force separation clutch. The clutch operating system of the small F is hydraulic and shares a hydraulic fluid with the brake system, so a tube is attached to the brake fluid tank.
ABS pump: safety device is very important Oh ~! ABS means automatic anti lock braking system, braking time, ABS system according to the vehicle speed, braking force of each wheel with automatic information such as dozens of times per second point brake, prevent tire slip and lock body, out of control. And it can provide steering ability when braking, so as to avoid obstacles.
Steering pump: provides hydraulic power for steering power. Recently, some owners reflect the jar belt abnormal sound problems, is offset booster pump bracket, causing the booster pump pulley and other belt wheels are not in the same plane, and the pulley belt running when abnormal friction, noise.
Air conditioning compressor: the vaporization of refrigerant compressed into liquid, and then pump into the evaporator, produce the cool we need ~!
Exhaust manifold: the exhaust gas from each cylinder of the engine passes through the exhaust manifold into the exhaust manifold, then passes through a three yuan catalytic converter and silencer into the atmosphere. Because the exhaust heat of the engine is very hot, a protective shell is added here to play a role of heat insulation. See the hand sign, no, there's a X, which means you don't touch it, it burns, oh ~!
Oxygen sensor: detects the oxygen content in the waste gas and sends the signal to the engine control module to control the injection amount, so that the fuel can be fully burned and the emission is reduced. If the oxygen sensor is out of order, it is said that the engine will stay idle and the fuel consumption will increase sharply.
Clutch pump: small F clutch is hydraulic drive, by the clutch master pump fluid pressure, along the clutch tubing to the clutch pump to produce mechanical force, to promote the right of the separation lever, split clutch. Hydraulic is much better than a stay cable.
Gear shift cable: one end of the cable is connected to the gear lever in the cab, and the other end is connected to the selector and shift mechanism. Have a great influence on the cable shifting feeling, a gear jerky difficult, there may be a cable problem oh!
Starting machine: in fact, it is a small motor. When the key switch goes to the starting position, the starter rotates and drives the engine to rotate. The auxiliary engine starts to enter the working state. When a car starts a fire, the duration of the fire should not be too long, one second at a time. Several consecutive fires have not been successful, should be the key back, and so on for a few minutes, to start the machine heat dissipation
The time, and then re ignition. This prevents the boot machine from burning down.
Let's look at the gasoline pump, the rear seat opened, will see a black cap, it is below the fuel pump to remove the lid can be seen after the gasoline pump, it is installed in the tank, but the demolition tank is very troublesome, so open a hole in this place, in the fuel pump can damage easy replacement.
This is the way the tank is removed, so you can see the actual installation position of the gasoline pump.
The gasoline pump is removed, and that's what it looks like. Since it is called an oil pump, its function is not to mention the pump oil. O (a _ U) O steam pump gasoline pressure delivered by the oil pipeline to the nozzle, because of pressure, gas atomization nozzle can spray well, can mix with the air uniformly.
One of the most important considerations in the use of gasoline pumps is to keep the tank low. Don't wait for the oil lamp to light up before you go on, because it depends on the gasoline in the tank. If the oil is too small, the cooling effect will be worse, and the gasoline pump will be burned seriously.
Gasoline filter: installed in front of the right rear wheel, next to the tank, the role is to filter out the moisture in gasoline, impurities and gum, to prevent the fuel system congestion, to ensure the normal operation of the fuel supply device.
Brake tubing: the force that transfers the brake pedal.
Brake pump: the hydraulic pressure of the brake fluid is converted to mechanical force acting on the brake caliper. The friction plate on the caliper causes friction with the brake disc, which transforms the kinetic energy of the vehicle into heat energy and thus stops the car.
Stabilizer bar: reduce roll over steering and increase maneuverability.
Half axle: transfer the power of the engine to the wheel and drive the car.
Steering rod: control the steering of the wheel, adjust the toe.
Bottom arm, upper support arm: suspension member for connecting wheels and car body.
Cardan shaft: it is connected between two shafts, and the transmission angle between two shafts can be changed in a certain range. Because the front wheel is both to drive, but also to turn it ~!
Spring: elastic element, as a buffer. This is a helical spring, the truck uses leaf springs, and some high-end cars use air springs.
Shock absorber: hydraulic damping element that absorbs energy from the impact of the road and suppresses the resilience of the spring after compression. It is combined with spring to form a shock absorber system to slow down the car body vibration caused by uneven road surface. The damping force of the shock absorber and the spring force of the spring are adjusted and matched to produce different chassis styles, such as sport type and comfortable type.
Handbrake cable: pull the handbrake when the rear wheel brake, with bicycle brake almost.
The soft connection of the exhaust pipe: to block the transmission of engine vibration.
Subframe: suspension member that connects the lower arm and the body.
Three yuan catalyst: the waste gas in the NOX, CO and other harmful gases into N2, CO2 and other harmless gas, reducing emissions pollution.
Silencer: eliminates the noise of engine exhaust. Without this, our car would roar like a sports car
.
Carbon canister: packed in a black car on the right side of the pot, filled with activated carbon, adsorption effect is connected with the tank, gasoline vapor. Gasoline is volatile fuel, fuel tank will soon increase the tank internal pressure, when the pressure reaches a certain value will have a certain risk, so people try to balance the pressure, first made fuel tank cap
The pressure limiting valve, when the pressure is higher than a certain value, the pressure limiting valve is opened, the gasoline vapor sent into the atmosphere, then people start to save out of fuel and protect the environment point of view, set up the carbon canister, activated carbon tank by strong adsorption tank filled with excess fuel vapor no longer discharged into the atmosphere, but has a tube into the carbon canister. Activated carbon is used to absorb fuel vapor,
When the car is running, the activated carbon canister solenoid valve opens in time, and the absorbed fuel vapor is re poured into the intake manifold to save fuel and protect the environment.
Torsion beam: a torsion beam type semi independent suspension member that produces a torsional deformation between suspension and non independent suspension. The suspension is characterized by low cost, high strength, small footprint, comfort, and more for small cars.
