How about doing car maintenance?

It's good. Nowadays, the automobile industry is developing rapidly, and the auto repair industry is all the way popular, and auto repair talents are very popular.

The composition "Me and my auto repair major" is 600 words. I love my major. When it comes to "auto repair", people think of those rough hands covered with oil stains. At first, I didn't know much about auto repair. I was young and ignorant, and I didn't know what auto repair was. I only know that car repair is to repair a broken car.

If I could own a car, it would be my dream. I just keep my love for cars deep in my heart. Although I am a little carsick, it doesn't hinder my love for cars.

With the growth of my age, my knowledge of cars is getting richer and richer. 1886, the world's first car came out.

100 years, with its speed and carrying capacity, cars have accelerated the pace of people's lives, enriched people's lives and changed the face of society. Especially with the development of science and technology, almost all new scientific and technological achievements and technologies have been applied to modern automobiles. The development of a country's automobile industry represents its comprehensive national strength and modernization. With the deepening of my understanding of cars, I have a deep understanding of cars.

Faced with filling out the volunteer form, I made a summary of my hobbies. Since I can't realize their wishes, I still have a long way to go. I can't go to high school I am studying new skills in vocational high school, which is the best in my major. But what major do I want to fill in? While I was thinking, I heard my father say that I wanted to buy a car. The word "car" immediately came to my mind. I majored in automobile operation and maintenance. This not only shared my similar hobbies, but also solved the problem of my father repairing cars in the future. At home, I don't need to pay someone else to fix it. I made a survey on the development of today's society. Now that people's living standards have improved and the number of cars has increased rapidly, there must be a large number of technical maintenance personnel. I don't think God will close one door, but he will open another.

I am waiting for the news of the admission notice at home. As time goes by, my heart is getting more and more nervous. I thought about what to do if I couldn't get in. To be safe, I asked my father to find a repair shop and let me be an apprentice there.

The very next day, when I was preparing to be an apprentice, the admission notice came. I was so happy to get the admission notice that I smiled and held it in my arms. Although I have a vocational high school admission notice in my hand, I am just as happy. On the same day, the school leader sent a caring greeting on the phone. Have you received the notice? I am very happy to reply. I know, thank you! In the autumn of 20 10, I entered Jinling secondary vocational school with longing for learning. It didn't go well at first, and I never left home. I wonder what it will be like to leave home every day. Now I have tasted the feeling of running away from home, which is really hard. I plan the future. I have the courage to go forward. In order to learn the real skills as soon as possible, I feel that this major is very hard, and the road is my own choice. No matter whether the road ahead is smooth or rugged, I will go forward bravely.

Since you have chosen the major of "Auto Repair", you should be responsible for yourself. Although the road to auto repair is bumpy and full of thorns, I have a deep love for auto repair, and I must give up the idea of being afraid of suffering. I believe I can do it. I cherish it and am determined to learn it.

I try to combine the theory and practical skills of the certificate, and combine diligent study with good thinking to further improve the image and abstract thinking. My major has given me a broad vision, knowledge and happiness, and also opened a window for me. From this window, I saw my goal and my future, and I will know more about automobile maintenance. I believe I will be the pride of middle school students.

I love my major. Although I worked hard, I found myself.

I love my major and experience the infinite power of happiness and knowledge.

I love my major, which embodies my pursuit and understanding of the true meaning of life.

Cars of the future Today's cars often emit black smoke because they use gasoline and diesel as fuel, which is seriously polluted and unsafe.

So I want to invent a future car, which is environmentally friendly, energy-saving and safer.

I think the future car should be driven by solar energy, so the body of the future car should be equipped with solar cells.

As soon as the sun shines, the car will have energy, not only driving fast, but also not emitting black smoke.

If it rains, you can use the electricity usually stored in high-energy batteries.

Many people can't drive.

In the future, cars will drive automatically. Cars can not only identify their own roads, but also automatically avoid various obstacles, automatically identify traffic signals, and automatically stop in case of emergency to ensure the safety of passengers.

Each car is equipped with a computer with detailed maps of all parts of the country.

Where the owner wants to go, as long as he clicks the place with the mouse, the car will find the best route and arrive in the shortest time.

Nowadays, the quality of cars is not high, there are too many accidents, and cars often break down on the road.

In the future, cars can be automatically maintained and repaired.

Once a fault occurs, the car will start an emergency plan and automatically search for maintenance points through satellites for maintenance.

In this way, passengers are much more relaxed.

This is a dream of mine. I must learn my skills well and realize my dream.

If you want education and technology, it is more appropriate to choose two-year professional automobile maintenance and operation engineers and automobile inspection and operation engineers in our school.

If you just want to learn technology, you can choose1April senior technician major in automobile inspection and maintenance and1October senior technician major in automobile 4S maintenance.

If you want to start a business, you can choose 5 months of car body painting and 2 months of car beauty decoration.

How to write an essay about flying cars: Flying cars In the 23rd century, there are many cars in the sky.

Why is the car in the sky? Because of the high-tech era, of course there will be cars flying in the sky.

Flying cars emit not exhaust gas, but oxygen that is indispensable to human life.

Flying cars don't need to be driven by people, because there is a special device in the car, which is as smart as people.

There is a microphone in the car, and the words coming from this microphone are the commands to be executed by that special equipment.

Flying cars also have the most magical function, that is, "air deformation."

"Deformation in the Air" is made for no car accident in the sky.

"Air deformation" can change animals flying in the sky, animals running on the ground and animals swimming in the water, and can also enlarge, shrink, lengthen and shorten.

Moreover, these "deformations" can be "deformed" not only when the car is about to collide, but also at other times.

After listening to my introduction, do you want to see it now? Don't worry, you will see flying cars in two centuries.

Article 2: There are flying cars everywhere in Beijing now, and 30,000 to 40,000 new cars are on the road every month.

At this rate, Beijing will become a big parking lot sooner or later.

So I want to make a new high-tech car-flying car.

The wheels of a flying car are connected to the body, and there is a magnetic levitation radio in the wheels.

Whenever the car starts, the maglev radio will emit moderate sound waves, which will make the car rise into the air.

But at most, it can only soar to 100 meters, and it will not compete with the plane for traffic resources.

The body of a flying car is very strong and not afraid of collision.

Someone wants to ask: "What if there is a traffic accident in midair, especially if the radio is damaged and the car falls?" No problem! Once hit, the car will pop up an airbag with a thickness of 10 m when it falls, and it will not be damaged when it falls from a height of 100 m.

Flying cars have a good anti-theft system.

Before the door is opened, the owner must aim his eyes at the keyhole.

It also has an automatic driving function.

If you feel tired during long-distance driving, you can tell the navigator your current position and expected destination, and the computer system of the car can drive safely for you.

Most importantly, flying cars are typical green cars, using only solar energy and no fuel.

If this kind of car is popularized, there is no need to build roads, which can save our precious land resources.

I want to invent a flying car with many control buttons on the basis of the original car.

If I'm going to be late for school and caught in a traffic jam, I can press the take-off button. At this time, the front of the car can be shrunk to a sharp point, with one wing on each side. The car can take off like a plane and fly to my school soon, so I won't be late.

If you have a very important performance coming, and you happen to meet several red lights on the road, you can fly in the air with this flying car, so that you won't run the red lights and be late.

I invented a flying car, which can bring a lot of convenience to mankind. Do you really want to buy one and enjoy it?

Love my campus, love my professional auto repair composition model essay Dear teachers and students: Good afternoon! I'm Li Bao from 15.

I am honored to attend this speech on behalf of 12 Spring Auto Repair Class 3, and share my learning experience with you. The topic of my speech today is my dream of auto repair.

Everyone has their own dreams to pursue, and we will always face some choices on the road of dreams.

I am glad that at the crossroads of my life, I chose Xunyang Vocational School and chose the major of automobile maintenance.

When I first entered the campus, I was at a loss, suspicious and hesitant.

I often ask myself, can I do it? See alumni wearing special training clothes, busy; When I heard the well-trained, dignified and powerful password for skill selection in the contest; When I touched the medals of various skill competitions held by seniors; There is infinite * * * in my heart.

I am determined to be as skilled as them, and one day I can represent our school and Shaanxi Province in the national competition! I believe that through unremitting efforts, my dream will come true one day. Slowly, I understand that cars are not just vehicles running around on the road. Behind every car, there is a huge working team. The birth of every dynamic car is full of advanced technology, superhuman wisdom, unremitting efforts and infinite love for auto mechanics. On the road of pursuing my dream, I gradually realized that the study of automobile specialty must combine practice with theoretical foundation; Therefore, the disassembly and assembly of the engine, the detection of the electric horn, the maintenance of the chassis, and the maintenance of the car; Not only enriched my study life, but also made me realize the truth that "you can only be a master if you suffer", and made me believe that the strength of the team is the most powerful weapon to overcome difficulties.

I don't know anything about cars, I'm interested in cars, and I'm willing to know and study cars in depth.

All this stems from my love for my major. This love makes me eager to learn more detailed automobile professional knowledge, which has laid a solid foundation for becoming a real autobot.

My ideal garage composition My father took me to visit the garage after school today.

Cars of all colors are parked in Li Xiu factory, including white, black, blue and red ... cars of all colors and sizes.

Rows of cars parked neatly, as if we were in line. The two shining headlights in front are like human eyes. When they are opened at night, it's like people screaming "Attention, excuse me ..." Do you think it's strange to hear my father say that cars still have "hearts" ... My father also told me a lot about cars, but I don't know much about them, but I think as long as I ..

My grandfather is an expert in car repair. He is a senior mechanic. He graduated from Lan Xiang Automobile College. He can repair various brands of high, medium and low-grade vehicles, such as Lamborghini, Maserati, Bentley and Ferrari. He can repair BMW, Hummer, Haima, Benma, Land Rover, Lubao, two R marks and one Q mark.

The first revised composition, about 300 words in a blink of an eye, has reached the first grade and everything has changed.

Next is our first evening self-study, which is undoubtedly a challenge for us.

"Ding, Ding ..." With a clear and crisp electricity * * *, the night lessons finally arrived.

This class is from China. Everyone put Chinese textbooks and notes neatly on the desks early and waited quietly for the teacher to arrive.

The Chinese teacher came later.

I quickly sat down and prepared to stand up. I didn't expect the first sentence of the Chinese teacher to be: "Take out your homework and do it. Preview the new lesson when you are finished. "

"Why, no class? I was surprised, but then I thought, self-study in the morning, self-study at night, and teacher guidance, aren't they all the same? No wonder ... maybe my classmates want to refuel as I think.

Then we finished our homework one by one, and some people did some unfinished homework in advance.

During the break, the students talked about everything in the corridor, some talked about the feelings of self-study at night, some worried about going back without street lights, and so on.

How beautiful! Eyes are full of lights, colorful neon lights, golden street lamps, stretching far and far. The whole street is full of colorful lights, just like a fairy tale world.

But it didn't last long. There are no street lamps on Sleeping Tiger Road. My classmates and I groped in the dark, riding the bike carefully, not daring to slack off.

Sometimes a car comes, and the dazzling lights make us blind, but we can't close our eyes, so we can only go home trembling.

"It's good to be the first time!" "The first experience is not necessarily pleasant, but it is fresh and unforgettable.

"Today, I really realized the truth that' the first time is really good'. Although very nervous, but very fresh and very * *.

I will never remember this first time!

Abstract: With the wide application of electronic technology in automobiles, automobile circuit diagram has become the necessary technical data for automobile maintenance personnel.

At present, most cars are equipped with many electronic control devices, which are high in technology and complicated in circuit, so it is difficult to master them.

It also needs some skills to read the automobile circuit diagram correctly.

Circuit diagram is an important information to understand the work of various electrical systems of automobiles. It is very important to understand the types and characteristics of automobile circuits, the circuit characteristics and expressions of automobile systems, and the reading methods, rules and skills of circuit diagrams of various systems, so as to guide readers how to read and use circuit diagrams correctly.

The automobile circuit is a single-wire parallel circuit. Generally speaking, there are series, parallel and series-parallel circuits in local circuits.

In fact, the whole vehicle circuit is composed of various circuits, and each circuit can be separated independently, simplifying the complexity.

According to its basic purposes, the vehicle circuit can be divided into lighting, signal, instrument, starting, ignition, charging, auxiliary and other circuits.

Each circuit has its own load conductor connected to the control switch or fuse box.

Keywords: (1) catalogue of all kinds of lights in the unidirectional conductor system of the circuit; (2) basic requirements for reading the circuit diagram; (3) taking Dongfeng EQ 1090 freight car line as an example, reading the whole car line A, power system line B, starting system line C, ignition system line D, instrument system line E, lighting and signal system line 4. In addition, electricity is invisible and intangible, so the automobile circuit is very complicated for many people.

But everything has its regularity, and car circuits are no exception.

General household electricity is a two-wire parallel circuit of alternating current, and electrical appliances have at least two external power lines.

From the automobile circuit, the negative wire (return wire) of the load (electrical appliance) should be directly connected to the negative terminal of the battery. If this wiring method is adopted, hundreds of wires will be connected to the negative terminal of the battery.

In order to avoid this situation, the designer uses the metal frame of the car body as the negative pole of the circuit, such as the girder.

Therefore, the automobile circuit is obviously different from the general household electricity: the automobile circuit is all DC, and the single-wire parallel circuit is implemented, as long as the electrical appliance has an external power line.

The negative pole of the battery and the negative pole of the load are connected to the metal frame, which is also called "grounding".

In this way, the negative lead from the load can be connected nearby, and the current flows back to the negative lead of the battery through the metal frame.

With the increasing application of nonmetallic materials such as plastic parts in automobiles, many automobiles now adopt public grounding grid wiring harness to ensure the reliability of grounding, that is, the negative wire of the load is connected to the grounding grid wiring harness, and the grounding grid wiring harness is connected to the negative electrode of the battery.

The automobile circuit is a single-wire parallel circuit. Generally speaking, there are series, parallel and series-parallel circuits in local circuits.

In fact, the whole vehicle circuit is composed of various circuits, and each circuit can be separated independently, simplifying the complexity.

According to its basic purposes, the vehicle circuit can be divided into lighting, signal, instrument, starting, ignition, charging, auxiliary and other circuits.

Each circuit has its own load conductor connected to the control switch or fuse box.

Lighting circuit refers to the circuit system that controls the combination switch, headlights and small lights; Signal circuit refers to the circuit system that controls the combination switch, turn signal and alarm light; Instrument circuit refers to the ignition switch, instrument panel and sensor circuit system; Starting circuit refers to the ignition switch, relay and starter circuit system; Charging circuit refers to the circuit system of regulator, generator and battery.

The above circuit system is essential and constitutes the basic part of the vehicle circuit.

Auxiliary circuit refers to the circuit system that controls wipers, stereos, etc.

With the increase of automobile electrical equipment, such as electric seats, electric doors and windows, electric skylights, etc. There will be more and more auxiliary circuits.

The circuit of an old car is relatively simple. Generally, their positive wires (commonly known as live wires) are respectively connected with the fuse box, and their negative wires (commonly known as ground wires) are used for * * *. There are three important nodes, namely fuse box, relay and combination switch. Most circuit systems have fuses or switches at one end and relays or electrical equipment at the other.

However, with more and more electrical equipment in modern cars, there will be more and more wire harnesses and wiring will become more and more complicated.

With the development of automobile electronic technology, modern automobile circuits have been combined with electronic technology, and multi-channel control devices have been adopted, instead of being transmitted through separate wires like old cars.

The multi-channel control device is used to convert the input signals from various electrical loads into digital signals through the electronic control unit (ECU), and transmit the digital signals from the sending device to the receiving device, where they are converted into required signals to control related components.

Therefore, it is necessary to add a multi-channel control device in the circuit between fuse, switch and electrical equipment (see the schematic diagram of Guangzhou Accord rear fog lamp circuit).

A system use multiple control lines can.

The second part of the second part briefly introduces the principle, requirements and methods of vehicle reading line and the specifications of circuit lines.

This paper mainly expounds its application in Dongfeng EQ 1090 automobile circuit and electrical system.

It includes power supply system, starting system, ignition system, lighting and signal system, instrument system and auxiliary electrical system.

Through the systematic study of Dongfeng EQ 1090, it lays a solid foundation for future contact with various types of vehicles.

First, the connection principle of the vehicle line The vehicle line varies according to the vehicle structure, the number of electrical equipment, the installation location and the connection mode, but its line is generally the following principles: (1) Most electrical equipment in the vehicle is connected by single wire; (2) The two power sources (generator and battery) equipped on the vehicle must be connected in parallel; (3) All kinds of electrical equipment are connected in parallel and controlled by their own switches; (4) The ammeter must be able to detect the charging and discharging current of the battery.

Therefore, whenever the battery supplies power, the current must pass through the ammeter and the battery. ...
