The total mass of a vehicle refers to the weight of the vehicle itself and the sum of the weight of the loads, passengers, and cargo it carries. Total mass is made up of several components, including the following elements:
Curb weight (empty vehicle weight):This refers to the weight of the vehicle when it is not carrying any cargo or passengers. It includes the structure of the vehicle, the engine, the chassis, the body and the basic equipment of the vehicle.
Load Mass:Refers to the maximum cargo and passenger weight that a vehicle can carry. The weight of this part of the load affects the overall mass of the vehicle.
The weight of the passenger and his/her baggage:The weight of each passenger and their carry-on items is also included in the total mass of the vehicle. This includes passengers, baggage, and any additional equipment.
Fuel Quality:The amount of fuel carried by the vehicle also increases the total mass. The fuel reserve is also part of the total weight of the vehicle when it is fully fueled.
Fluids & OthersSome vehicles may also carry additional fluids at different points in time, such as engine coolant, brake fluid, etc. The mass of these fluids is also included in the total mass of the vehicle.
In general, the total mass of a vehicle refers to the sum of the weight of the vehicle itself, the passengers, the cargo, and the required fuel and liquids during operation. The total mass of the vehicle has a significant impact on both road safety and vehicle performance, so it is very important to control and maintain the total mass of the vehicle within the specified range.
Summary: The total mass of the vehicle includes the weight of the vehicle itself, the sum of the weight of the load such as passengers, cargo, fuel, etc., which is an important factor affecting the performance and safety of the vehicle.
