Car classificationWhat is the classification standard?

1. The car grade is generally: a00, a0, a, b, c and d. The wheelbase of the a00 passenger car is between 2 meters and 3 meters, and the engine displacement is less than 32313133353236313431303231363533e4b893e5b19e313334313636301 liters, such as Otto and smart At a00-level passenger car.

2. The car grade is generally: A00, A0, A, B, C and D. At the beginning of the promotion of its platform strategy, German Volkswagen divided the model platforms into six levels: A00, A0, A, B, C and D according to their size and positioning.

3. The car grade is generally: A00, A0, A, B, C and D, which is a classification method for automobiles derived from Volkswagen in Germany. It is not an authoritative standard, but a set of reference values formulated by Volkswagen when it formulated a platform strategy for itself, which was later widely General use.

4. The car grades are generally: A00, A0, A, B, C and D. The detailed classification instructions are as follows: The wheelbase of A00 passenger cars should be between 2 meters and 3 meters, and the engine displacement should be less than 1 liter. The wheelbase of A0-class A0 passenger car is 3 meters to 5 meters, and the displacement is 1 liter to 5 liters.

Automobile What does the car class classification standard mean?

According to the standards of mainland China, it is divided into: mini car (disspostment of less than 1L), ordinary car (dispment of 0~6L), intermediate car (dispastment of 6~5L), medium and high-end car (dispastment of 5~0L), luxury car (distch is 4L Above).

A-class cars A-class cars are divided into three levels, namely A00, A0 and A.

They are divided into different levels,In fact, it is divided according to the different standards of wheelbase, length, displacement and quality of the vehicle.

Automotive Emission Standards

1. China's automobile emission standards: The specific implementation so far has been mainly divided into six stages, namely National I, National II, National III, National IV, National V and National VI.

2. The carbon monoxide emitted by a car per kilometer cannot exceed 1,000 mg. The non-methane hydrocarbons emitted by cars per kilometer cannot exceed 68 milligrams. The nitrogen oxide emitted by a car per kilometer of driving cannot exceed 60 milligrams. The pm fine particulate matter emitted by a car per kilometer should not exceed 5 mg.

3. Automobile exhaust emission standard value IV standard: The measurement standard of exhaust must be related to speed or engine speed, otherwise the measured data is inaccurate and inconsistent.

4. The fourth national emission standard is the fourth national emission standard for motor vehicles. The pollutants emitted by cars mainly include hydrocarbons, nitrogen oxides, NO _ 1), PM, etc.

5. The national five automobile exhaust emission standards are equivalent to the European Union's five standards. The European Union has been implementing it since 2009, and its restrictions on motor vehicle emissions such as hydrocarbons, nitrogen oxides, carbon monoxide and suspended particles are stricter. From National One to National Five, every time the standard is raised, bicycle pollutants are reduced by 30% to 50%.

6. Automobile emission standard country V refers to the exhaust gas emission that meets China's standard emission standard country V, and the standard is the content of harmful substances in fuel exhaust emissions. The national standard gasoline sulfur content is 150mg/kg, the national standard diesel is 50mg/kg, and the national six diesel is 10mg/kg.

What is the standard for cars?

1. The types of motor vehicles and the classification standards of motor vehicles are as follows: large passenger cars refer to: vehicles with a length of more than 6m or more than 20 passengers (including drivers). Medium-sized passenger cars refer to: the length of the vehicle is less than 6m, and the number of passengers is more than 9 and less than 20 people.

2. Motor vehicle type and motor vehicle classification standard: large passenger car: the vehicle is more than 6m long or the number of passengers is more than 20 people (including the driver). Medium-sized passenger car: the length of the car is less than 6m, and the number of passengers is more than 9 and less than 20 people. Small passenger car: the length of the car is less than 6m, and the number of passengers is less than or equal to 9 people.

3. The following are the criteria for the definition of motor vehicle types: large passenger cars: the vehicle is more than 6m long or the number of passengers is more than 20 people (including the driver).Medium-sized passenger car: the length of the car is less than 6m and the number of passengers is more than 9 and less than 20 people. Small passenger car: the length of the car is less than 6m and the number of passengers is less than or equal to 9 people.
