1. Quality parameters. There are three important contents: gross weight, rated quality and net weight.

    The quality of the truck is also the weight of a car, namely net weight. It is defined as the net or dry mass of the car plus the coolant and fuel (not less than 90% of the tank capacity) and the spare wheel and The total mass of the car accessories. So what is the net or dry quality of the car? Net or dry quality refers to the quality of a complete vehicle that is only equipped with the body, all electrical equipment, and the vehicle's normal driving. In layman's terms, the quality of the kerb is the quality of the empty car when the car is not ready to carry people (including the driver) and when carrying the cargo under normal conditions.

    The net weight of the truck is also an important parameter affecting the fuel consumption of the car. Because the fuel consumption of the vehicle is directly proportional to the quality of the kerb, that is, the car with the better quality is more fuel-efficient. Reasonable and lightweight vehicles can reduce the amount of oil, so to configure the vehicle for the user to understand the user's use, not blindly lightweight.

    Of course, the net weight of the truck is high, and it is also good. The stability of the car with good quality is good, especially when it is sharp turn and sudden braking. The advantage is obvious. Therefore, to comprehensively evaluate the performance of the car, the quality of the car's curb is also a parameter that cannot be ignored.

    The gross weight of a truck refers to the weight of the vehicle when it is fully equipped and filled with passengers (including drivers) and goods as required. But sometimes people call it "the maximum total mass of the manufacturer" and "allow the maximum total mass." It is important to note that these two concepts are different. The former is determined by the automobile manufacturer according to the specific conditions of use, taking into account the strength of the material, the bearing capacity of the tire and the like. The latter is stipulated by the competent authority according to the conditions of use of the car, and usually the latter value may be slightly lower than the former. The quality of the kerb is the quality of the empty car when the car is not ready to be loaded (including the driver) and the cargo is loaded under normal conditions.

    Rated quality is the difference between the total mass of the truck and the quality of the car. It indicates the total mass of the truck that can carry people and cargo, which is the effective loading capacity of the truck. This is an important performance indicator for trucks, buses and all types of cars. It has very practical meaning for users.

2. Geometric parameters. The parameters such as the length, width and height of the vehicle are specifically the length and width of the vehicle and the length, width and height of the internal dimensions of the container. It has practical significance for the specific bearing and passing of the vehicle.

3. Oil quantity parameters. The impact of the country’s recently defined fuel indicators on vehicle competition. This indicator affects the handling of the operation permit. The impact on vehicle sales in the future will be direct. The fuel consumption rate is expressed in g/(kw.h).
