1. Vehicle equipment quality (kg): The quality of the fully equipped vehicle, including the quality of all devices such as lubricating oil, fuel, on-board tools, and spare tires.
2. Maximum gross mass (kg): The gross mass of the car when fully loaded.
3. Maximum loading mass (kg): The maximum loading mass of the car when driving on the road.
4. Maximum axle load mass (kg): The maximum total mass carried by a single axle of the vehicle. It is related to the road passability. Try not to damage the acid and alkali objects during the use of the car.
5. Vehicle length (mm): The distance between the two extreme points in the length direction of the vehicle.
6. Vehicle width (mm): The distance between the two extreme points in the width direction of the vehicle.
7. Vehicle height (mm): The distance from the highest point of the vehicle to the ground.
8. Wheelbase (mm): The distance from the center of the front axle to the center of the rear axle.
9. Wheelbase (mm): The distance between the centerlines of the left and right tire treads of the same car.
10. Front overhang (mm): The distance from the front end of the car to the center of the front axle.
11. Rear overhang (mm): The distance from the rear end of the car to the center of the rear axle.
12. Minimum ground clearance (mm): The distance from the lowest point to the ground when the car is fully loaded.
13. Approach angle (°): the angle between the tangent line drawn by the protruding point of the front end of the car to the front wheel and the ground.
14. Departure angle (°): the angle between the tangent line drawn from the protruding point of the rear end of the car to the rear wheel and the ground.
15. Turning radius (mm): When the car turns, the radius of the track circle of the center plane of the steering wheel outside the car on the vehicle support plane. The turning radius when the steering wheel is turned to the extreme position is the minimum turning radius.
16. Top Speed (km/h): The maximum speed a car can reach when driving on the road.
17. Maximum grade (%): The maximum gradeability when the car is fully loaded.
18. Average fuel consumption (L/100km): The average fuel consumption per 100 kilometers when the car is on the road.
19. Number of wheels and number of driving wheels (n×m): The number of wheels is based on the number of hubs, n represents the total number of wheels of the car, and m represents the number of driving wheels.
20. Compression ratio: The compression ratio refers to the ratio of the total volume of the cylinder to the volume of the combustion chamber, which indicates the degree to which the gas in the cylinder is compressed when the piston moves from the bottom dead center to the top dead center. Compression ratio is an important parameter to measure the performance index of automobile engine.
21. Displacement: The working volume of the cylinder refers to the gas volume swept by the piston from the top dead center to the bottom dead center, also known as the single-cylinder displacement, which depends on the cylinder bore and piston stroke. Engine displacement is the sum of the working volumes of each cylinder, generally expressed in milliliters (CC). Engine displacement is one of the most important structural parameters. It can better represent the size of the engine than the cylinder diameter and the number of cylinders. Many indicators of the engine are closely related to the displacement.
22. Torque: Torque is the force that makes an object turn. The torque of the engine refers to the torque output by the engine from the crankshaft end. Under the condition of fixed power, it is inversely proportional to the engine speed. The faster the speed, the smaller the torque, and vice versa, it reflects the load capacity of the car within a certain range.
