What are the maintenance techniques for ignition and fuel system failures of automobile engines?

1. In the process of overhauling the high-voltage circuit, the detection method is high-voltage testing. Through this overhaul technology, the cause of the failure can be determined.

2. Whether the car engine fails is still a little obvious. Analyze the engine failure from the abnormality of the exhaust color. The color of the exhaust gas after normal combustion of gasoline should be colorless, and when the engine fails, the color of the exhaust gas will change. First, the exhaust gas is black because the fuel is not fully burned.

3. Replace the air filter and fuel filter: If it is found that the fuel consumption has increased, it may be caused by the blockage of the air filter or fuel filter.At this time, these filters need to be replaced in time.

4. The above introduces the common faults of automobiles and the relevant content of maintenance knowledge. Let's take a look at the common faults of automobiles.

5. The current maintenance requirements for automobile engine failure are based on a sound maintenance theory. Compared with the technical level of automobile engine fault maintenance in Western developed countries, there is a large room for the development of engine fault maintenance technology in China's automobile industry, and research needs to be strengthened in terms of application.

6. Compared with gasoline engines, the advantages of diesel engines are that diesel is cheap and economical, and it does not have an ignition system, so there are fewer failures.

Automobile engine maintenance technology?

1. Engine maintenance: including engine disassembly, cleaning, inspection, maintenance and assembly and other technologies. Transmission maintenance: including transmission disassembly, cleaning, inspection, maintenance and assembly and other technologies. Electrical system maintenance: including fault diagnosis, maintenance and replacement of automotive electrical systems and other technologies.

2. In addition, automobile maintenance technology can also be based on the category of automobile engines.Type and use status, choose suitable technologies such as car engine cleaning, lubrication and engine maintenance to ensure the normal operation of the car engine.

3. The problem of burning engine oil in cars is familiar to the owner and the maintenance master, which is painful. There are also various reasons for burning engine oil. Today, the editor of Schmoqi Repair will explain the knowledge of engine maintenance - the cause of oil burning failure.

4. The engine starts cold car. After starting, the engine vibrates, and then tends to stabilize. The medium and low engines begin to shake. In this case, the spark plug and ignition failure, if it is not a spark plug failure, the ignition time may be too early. If the above fault occurs, it should be repaired at the repair shop in time.

5. Engine oil, that is, engine lubricating oil, can play the role of lubricating and reducing wear, auxiliary cooling, sealing and anti-leakage, anti-rust and anti-corrosion, shock absorption and cushioning of the engine.It is known as the "blood" of cars. Oil is composed of two parts: base oil and additives.

6. Learning engine maintenance technology is relatively easy to learn. The main thing is to learn the mechanical part first, and this part should be practiced more. The second is the disassembly and installation part. The electronic control part should listen to the teacher's explanation for corresponding detection and measurement.

What professional technologies are included in car maintenance?

Automotive engineering technology: This is a major that covers knowledge of automobile design, manufacturing and maintenance, including engine, chassis, electrical control system, etc. Automobile application and maintenance: This is a major that focuses on practical operation. Students will receive training on car troubleshooting, maintenance and testing.

The auto repair major includes many directions, including the reception direction of the automobile front desk, the direction of automobile decoration and beauty, the direction of automobile sheet metal spraying, the direction of automobile manufacturing technology, the direction of automobile inspection and maintenance, and the direction of automobile electrical appliances inspection and maintenance.

Professional classification: Auto repair enterprises will divide the types of work into automobile circuit, automobile sheet metal, automobile painting, automobile air conditioning, automobile machinery. The mainstream projects are automobile electromechanical, automobile sheet metal spraying, and automobile beauty. Relevant schools will also set up three majors in this way.

Abstract: Auto repair major is to train automobile maintenance professionals. There are many types of auto maintenance, and auto repair is also divided into several majors, including automotive circuits, automotive sheet metal, automotive painting, automotive air conditioning, automotive machinery, etc.

New energy vehiclesTechnical engineer New energy vehicle technology mainly studies the basic knowledge and skills of new energy vehicle composition structure, battery design, fault diagnosis, maintenance and maintenance, etc., and carries out the production and manufacturing, assembly and debugging, inspection and maintenance of new energy vehicles, etc.

Auto repair majors mainly include automobile service engineering, automobile sales and evaluation, automobile inspection and maintenance, etc.

What are the car maintenance methods

If the battery is dead, make a rescue call or find a car to check, and then go to the service station to charge the battery. If the tire is flat, a specialized repair shop will repair or replace it. Significant increase in fuel consumption: After using the car for a period of time, many car owners will find that the fuel consumption has suddenly increased by more than 10%, which is puzzling.

It loses its original performance, and it will also cause oil bonding and oil spare deformation, which is easy to cause fire. The best practice is to choose suitable engine oil according to the lowest local winter temperature. Where conditions permit, it is best to park the vehicle in a garage with insulation facilities.

The basic faults and maintenance methods of the car are as follows: the battery is insufficient, and emergency power supply is needed to start the vehicle. The vehicle is difficult to start, and the spark plugs and fuel injectors need to be checked. The steering wheel suddenly becomes heavy during use, and it is necessary to check whether the vehicle's assistance system is damaged or lacks lubricating oil.

This method is to use the knowledge we have learned and various detection equipment to gradually find faults. This method is often used for some soft faults and difficult problems. Example: A Mitsubishi V6 sedan, increase the throttle speed up to 3000r/min.We first check the ignition system, replace the spark plug, and measure the high-voltage line to meet the standard value.
