State-recognized third-party automobile appraisal agency

1. Third-party appraisal agency for new cars is generally in the National Automobile Quality Supervision and Inspection Center, and the national motor vehicle product quality supervision and inspection The inspection center, the National Automobile Quality Supervision and Inspection Center, and the National Automobile Quality Supervision and Inspection Center can carry out new car inspection.

2. At present, in China, the main third-party automobile testing institutions include the China Parking Association, the China Quality Certification Center, the National Motor Vehicle Quality Supervision and Inspection Center and many other institutions. These institutions are certified by the government or other professional institutions, have credibility and authority, and can provide authoritative and effective automobile testing services.

3. The vehicle appraisal institutions recognized by the court include: China Automobile Inspection, Dr. Cha, China Automobile Technology Research Center Co., Ltd., etc. China Vehicle Inspection: Founded in 2009, it is the governing unit of China Automobile Circulation Association, providing vehicle inspection, vehicle valuation and other services.

Basics of hybrid vehiclesStructure

1. The structure of hybrid cars is relatively complex. It has the dual components of traditional cars and pure electric cars. As shown in the figure, hybrid vehicles are equipped with internal combustion engines, power batteries, power drive units, DC/DC converters. If it is a plug-in hybrid vehicle, it is also equipped with on-board chargers, etc.

2 The engine and drive motor of 2 parallel hybrid vehicles (PHEV) are powertrains, and the power of the two powertrains can be superimposed on each other or output separately.

3. (2) Hybrid cars are mainly divided into series (SHEV) and parallel (PHEV) according to the form of energy synthesis. ( 3) The serial force is composed of an engine, a generator and an electric motor, which are connected in series to form the power unit system of SHEV.

What are the five major systems of the four automobile institutions?

1. The four major systems are for the chassis, namely: transmission system, driving system, steering system and braking system. Transmission system Automobile transmission system mainly refers to the power transmission device between the automobile engine and the drive wheel, mainly including clutch, transmission, universal joint, transmission shaft, differential, main reducer and semi-shaft, etc.

2. The five major systems are fuel supply system, lubrication system, cooling system, start-up system, and ignition system. The three major structures include the crank connecting rod mechanism, the body unit, and the gas distribution mechanism. 1. Cooling system: generally composed of water tank, water pump, radiator, fan, thermoster, water temperature gauge and water release switch, etc.

3. The five major systems of the three major mechanisms are: crank connecting rod oil, gas distribution mechanism and transmission mechanism. Five major systems: fuel supply system, cooling system, lubrication system, ignition system (electrical control system) and start-up system.

What are the basic structures of cars?

1. The chassis of the car: The function of the chassis is to support and install the car engine and its parts and assemblies to form the overall shape of the car, and receive the power of the engine to make the car move and ensure normal driving. The chassis consists of four parts: transmission system, driving system, steering system and braking system.

2. Cars are generally composed of four basic parts: engine, chassis, body and electrical equipment.

3. The basic structure of the car is: car engine, car chassis, car body, electrical equipment. Car engine The engine is the power unit of the car.

4. The basic structure of the car consists of four basic parts, including engine, chassis, body and electrical equipment.

5. Cars are usually composed of four major parts: engine, chassis, body and electrical equipment. The following is the relevant information: engine: crank connecting rod mechanism, gas distribution mechanism, fuel supply system, ignition system, lubrication system, cooling system and start-up system. Chassis: transmission system, driving system, steering system and braking system.

6. The basic structure of the car includes engine, chassis, body and electrical equipment. The following is a detailed description: Engine: The engine is an important part of the car, which provides power for the driving of the car.
