Some parts of the car, the name is very similar, for some car white, always silly and indistinct. Today, Lao Hou has sorted out the names of parts that are confusing on the car. Let's take a look at the difference between them.
Chassis and body outsole
This is a concept that many people will mistake. Everyone often talks about driving the chassis and doing it.
Chassis armor
The chassis rusted, and so on. In fact, what they say is not the chassis of the car, but the outsole of the car body. It is a whole piece of structure assembled from the front floor assembly and the rear floor assembly, and it is complete with the above ABC column and side walls. The body is part of the body structure.
The chassis of an automobile refers to the general term of the clutches, transmissions, drive trains, suspensions, steering systems, and brake systems. It is a functional part of the car.
Wheel rims and wheels
Wheels and wheels are two different things. Many articles confuse them, but in fact they are two very different parts. As shown below.
The hub is mounted on the shaft tube or knuckle (the brake disc is mounted on the hub) by means of a conical ball bearing. The rim is used to mount the tire and it is connected to the hub by a tire screw.
Generator belt and timing belt
Many vehicles use timing belts, but many people do not know which one is the timing belt. The belt that is exposed on the front of the engine and wound around the generator is a timing belt. It is actually a generator belt that is used to drive the generator. Air conditioning compressors, steering pumps, etc. The real timing belt is invisible and is blocked by a cover.
Valves and Throttle
The valve is the valve that the outside air enters into the engine and the exhaust gas of the engine is exhausted. It is responsible for inputting air into the engine and discharging the exhaust gas. It is installed in the cylinder head of the engine. The throttle is a valve that controls the air to enter the engine and is installed in the air filter. Between the device and the intake manifold, controlled by the accelerator pedal, there are pull-wire type and electronic control type. Actually, fuel injection and oil reduction is to change the size of the throttle opening to control the size of the intake air, and the fuel system will then eject the corresponding The fuel is mixed with it to form combustible mixtures of different concentrations and amounts into the combustion chamber.
Differentials and differential locks
In the straight running process of the car, the rotation speeds of the two driving wheels are the same, but in the cornering, because the wheel travel distance is not equal, the rotation speed is certainly not the same. The function of the differential is to allow the driving wheels on the left and right sides to be different. The speed of operation. The differential lock is an accessory on the differential, but the effect is just the opposite of the differential. The purpose is not to allow the differential to work. It is not allowed to have the same speed on both sides of the drive wheel.
Axle and transmission shaft
Axle shafts are solid shafts that transmit the torque of the transaxle to the drive wheels, while the drive shafts transmit the torque of the transmission to the drive axle. There is no drive shaft on the front-wheel drive car, and both the drive shaft and the half-axis on the rear-wheel drive car.
Bumper and crash beam
Many people confuse the bumper with the anti-collision steel beam. In fact, they are two completely different components. The anti-collision steel beam is part of the body frame structure, especially the front anti-collision steel beam, which plays a crucial role in the body structure. However, the bumper is just a body exterior cover that does not have any effect on the safety of the vehicle body structure. At best, it can be buffered in a very slight collision.
Valve cover and cylinder head
Some vehicles have been used for a long time and the valve cover will leak. This is a small thing. However, some owners have no idea where they are. Everyone says that their own cylinder heads have leaked, and they startle some people who understand the car and think that the engine of this car is out of order. In fact, the valve cover and the cylinder head are two distinct components. The valve cover is attached to the cylinder head. The removal of the valve chamber cover is a very simple operation, and the disassembly and assembly of the cylinder head is very complicated, has a certain technical difficulty, requires the attachment and detachment of many attachments, and also takes a long time, and also has some damage to the engine.
Air filter and air filter
Air filter cartridges and air-conditioning filter cartridges are indistinguishable from their names. In fact, as long as you remember this point: air filter is to supply air to the engine, air filter is to supply gas to the people in the car. The air filter is generally installed in the engine compartment, and the air filter is generally installed in the co-driver's glove box.
Glass water, antifreeze
Glass water, as its name implies, is used to clean the front windshield; antifreeze is
Engine cooling system
The working medium has the effect of cooling the engine, preventing the cooling system from freezing and scaling.
It should be noted that these two liquids have different locations, so don't add them wrong. The wrong result is very serious.
Reviews
Some parts of the car, either with similar names or similar functions, are always confusing. Just like Fan Bingbing and Li Bingbing in the entertainment scene, for people like me who are blind, they have almost no difference. However, it does not matter if they do not recognize them. They do not know the parts on the car. The consequences can be serious. In the event that glass water is added to the engine one day, or the generator belt is replaced with a timing belt, you can wait for the output of Mao Yeye.
Liquefied natural gas transport ship referred to as LNG, the main transport liquefied natural gas. The main component of liquefied natural gas is methane, which is easy to transport, and it is usually used in the low temperature (- 165 degrees Celsius) freezing method to make it liquefied. Our country is not only a country with a series of LNG ship types after Korea, Japan and other countries, but also the design of ship type in China has obvious advantages in safety, energy saving and environmental protection.LNG ship is at 162 degrees Celsius (-162) special shipping liquefied gas under low temperature, is a kind of "super frozen sea car", has been hailed as the world's shipbuilding "crown jewel", currently only a handful of countries such as the United States, Japan, South Korea and the European Chinese, the shipyard can build 13.

LNG ship refers to the LNG (natural gas Liquefied) from the liquefied plant to the receiving station of the special ship. The tank of the LNG ship is independent of the special structure of the hull. In the design of the ship, the main factors considered are the materials which can adapt to the low temperature medium, and the treatment of volatile or flammable materials. Ship size is usually restricted by the conditions of the port and the receiving station. Currently 125 thousand cubic meters is the most commonly used in size, the largest size in the construction of the ship has reached 200 thousand cubic meters. The service life of LNG ship is generally 40 ~ 45 years.
From the ship was born to 2013, the world LNG tanker storage system mainly has two kinds of self support and thin film. There are two types of A type and B type, A type as the diamond or IHISPB, B type is spherical.
LNG receiving terminal has a dedicated terminal for LNG transport, ship berthing and unloading operation. Storage tanks for the storage of liquefied natural gas from the LNG transport ship. The re gasification device is to heat the liquefied natural gas into a gas, and the gas is transported to the end user through the pipeline. The cold energy released by LNG in the process of re gasification can be comprehensively utilized. In general, about 25% of the cold energy can be used.
technology
Look at the membrane type LNG carrier is better than MOSS in ship performance in general, but MOSS has the advantages of less restricted use, cargo loading operation and, in the early days of the LNG sea, MOSS ship has a large advantage.
According to the different types and construction methods, the liquid cargo hold of the thin film type ship is divided into No.96 type GTT type and Mark type III type, and No.96 GTT type insulation form is insulated box; Mark type III is composed of insulation board and rigid insulation material. The Hudong Zhonghua shipbuilding (Group) Co. Ltd. has successfully built the GTT No.96 type LNG ship. GTT No.96 has higher demand than the Mark type construction process in hull, whether in precision control or welding requirements, to build GTT No.96 requirements, basically also mastered the Mark type construction technology.
In the liquid cargo tank, the second layer of INVAR welding, No.96 GTT type can be a large number of automatic welding, welding quality control, and Mark type III manual welding more, welding quality is not easy to control.
structure
Liquefied natural gas (LNG) ship types according to the structure of the cargo tank have independent storage tank type and membrane type two kinds. Early liquefied natural gas (LNG) ship is independent storage tank type, is cylindrical, cylindrical and spherical shape of the storage tank in the boat. The tank itself has certain strength and stiffness. Structural member support and fixed effect to the tank only. Late 60 s, the film type LNG ship. This kind of double hull structure is used in ship hull inner shell is the carriage of the cargo tank shell. In the cargo tank lining has a membrane made of nickel alloy steel sheet. In contact with it and the cryogenic liquid directly, but only up to prevent liquid leakage barrier effect, both on the membranes of the liquid cargo to load through the membrane and the thermal barrier between the inner hull directly to the main hull. Compared with independent storage tank type, diaphragm type has the advantage of high volume utilization, structure, light weight, so the new LNG ship, especially large, membrane structure is used to most. The structure of materials and technology requirements. In addition, Japan also developed a half film type ship structure in between.
Liquefied natural gas (LNG) ship equipment complex, high technical requirements, volume compared with the deadweight of the same oil tanker is larger, so the cost is much bigger. Liquefied natural gas (LNG) ship is generally equipped with gas liquefaction plant again, can also transport liquefied petroleum gas (LPG).
