Model main parameter code
1. The main parameter code of trucks, off-road vehicles, dump trucks, tractors, special vehicles and semi-trailers is the total mass t of vehicles, and the total mass of tractors includes the maximum mass on the traction seat. When the total mass is above 100t, three digits are allowed. The main parameter code of an automobile is the engine displacement (L), which should be accurate to one decimal place and expressed as ten times its value.
2. Main parameter codes of special vehicles and special semi-trailers. If the difference between the main parameters and the main parameters of the original car is less than 10% of the original car, the main parameter code of the original car should be used, so the modified bus chassis can also be used to indicate the length of the car.
