Analysis of Specific Nouns for Automotive Product Announcement Parameters
Appearance size: Length × width × height: The unit is mm. Only the data part is filled in. When the data content is multiple, it is separated by a half-width format “,†with no space in the middle. The three types of chassis are not filled.
Product ID:
The “Product Number†field is unique. It is mainly used to provide the print certification because the same type of announcement may have more than one piece of data. These announcements may be made by several different manufacturers or may be produced by the same manufacturer but the announcement Different batches, in order to distinguish, each vehicle model uses a unique "product number" to distinguish, that is a product number represents a unique piece of data, the QR code inside the certificate will contain this field, through this The product number can determine which batch of announcements this model belongs to.
Fuel type:
1. Fill gasoline, diesel, LPG, CNG, diesel and LPG dual-purpose fuel, diesel and LPG dual fuel. One model cannot be filled with gasoline and diesel at the same time.
Remarks: LPG refers to liquefied petroleum gas, CNG refers to compressed natural gas, and diesel + LPG dual-purpose fuel refers to the use of two fuels after mixing. A model can only use the same kind of ignition: compression ignition or ignition, that is, the general gasoline, CNG, LPG are used ignition, and diesel compression ignition.
2, "pure electric" refers to pure electric vehicles.
Total mass: The total weight when fully loaded.
Maintenance quality: The quality of empty cars can also be said to be the weight of the car.
Rated load quality: The maximum load.
Maximum torque: Torque is an important parameter of engine performance. It refers to the average torque output from the crankshaft when the engine is running. It is commonly referred to as the engine's "turning force." The greater the torque, the greater the “strength†of the engine output, the faster the crankshaft speed changes, and the better the car’s ability to climb, start, and accelerate. Torque varies with engine speed. The speed is too high or too low. The torque is not the maximum. Only at a certain speed or within a certain speed range will there be maximum torque. This zone is given when the maximum torque is marked. Speed ​​or speed range. The maximum torque generally occurs in the middle and low speed range of the engine. As the speed increases, the torque will drop instead. The unit of torque is Newton metres (N·m) or kilograms (Kg·m).
Maximum power: The physical definition of power refers to the work done by a machine in a unit of time. The amount of work is certain, and the shorter the time, the greater the power value.
The formula for calculating power is: power = force * distance / time. The common unit of force is kilograms (kg), the unit of distance is meters (m), and the unit of time is seconds (s). So the unit of power is kg.m/s. However, for the power of cars, people traditionally like to use horsepower as the unit, and the letters are PS. Manufacturers usually also give kilowatts (KW) values ​​in product descriptions.
Chassis emission standards:
1. Fill in the existing national standards based on the test. If multiple emission standards are used, they should be separated by "," with no space in the middle.
2. If the standard is to be carried out in phases, the stages should be indicated according to the standard representation method (eg: GB17691-2001 Phase 2, GB18352.3-2005 State III).
