2021 Chengdu second-hand vehicle relocation emission standard is China VI. Below is the relevant introduction to China VI emission standards: 1. Emission regulations: China VI standard emission limits are China VI A: carbon monoxide 700mg/km, non-methane hydrocarbons 68mg/km, nitrogen oxides 60mg/km, PM fine particles 4.5mg/km, etc.; China VI B: carbon monoxide 500mg/km, non-methane hydrocarbons 35mg/km, nitrogen oxides 35mg/km, PM fine particles 3mg/km, etc. 2. Impact: After the implementation of the China VI standard, it only affects the registration of new China V vehicles. Already registered and annually inspected China V vehicles will not be affected in normal use.

Is driving 10,000 kilometers a year considered a lot?

Driving 10,000 kilometers a year is not considered a lot. Generally, the average mileage for a family car is around 15,000 to 30,000 kilometers. Below is some relevant information about vehicle mileage: 1. Composition of the car odometer: The car odometer actually consists of two meters, one being the speedometer and the other the odometer. The speedometer indicates the car's speed in km/h (kilometers per hour). The odometer is usually located directly in front of the driver's position. 2. Introduction to vehicle mileage: Typically, most people's cars travel around 50,000 kilometers per year, with 50,000 kilometers serving as a benchmark stage. Each stage of the total mileage requires relatively significant maintenance and repairs. Small and micro non-operational passenger vehicles have no usage time limit, with the maximum recommended mileage for scrapping being 600,000 kilometers.

What are the reasons for the steering column module failure in the Mercedes-Benz E260L?

The reasons for the steering column module failure in the Mercedes-Benz E260L are as follows: Incorrect front wheel alignment: The cause is incorrect front wheel alignment and insufficient tire pressure. Deformation or wear of the steering linkage, overly tight ball joints, lack of oil in the steering gear, excessive clearance in the steering gear meshing pair, bearing damage, or excessive preload. Function of the steering column module: The steering column is the component that connects the steering wheel to the steering gear in the steering system, primarily responsible for transmitting torque. Through the steering column, the driver transmits torque to the steering gear, enabling the steering gear to achieve steering. Common types of steering columns include hydraulic power steering columns, electro-hydraulic power steering columns, and electric power steering columns, each with different systems.

How many seconds does it take for the BMW 7 Series to accelerate from 0 to 100 km/h?

The BMW 7 Series has several models, such as the 740Li, which accelerates from 0 to 100 km/h in 5.39 seconds. RPM before launch: With the electronic stability control turned off and switched to SPORT mode, following the conventional launch control method, this 740Li can maintain a 3000rpm before launch. As soon as the brake pedal is released, the car delivers an extremely intense burst of acceleration. Actual 0-100 km/h driving time: As the acceleration process continues, the perceived force of the acceleration weakens, but this does not affect the 740Li's acceleration capability. Its 0-100 km/h time of 5.39 seconds is still faster than many competitors in its class.

What does a BMW electronic thermostat control open circuit fault mean?

BMW electronic thermostat control open circuit fault means that it is necessary to check whether the engine cooling system heater control circuit is open or whether the heater is damaged. How the electronic thermostat works: The ECU provides a duty cycle (PWM) signal operating voltage to the heating resistor element inside the electronic thermostat based on the calculated value derived from sensor signals, causing the wax to expand and displace. The temperature regulation unit mechanically adjusts the coolant flow between the large and small circuits through this displacement. How to handle an electronic thermostat control open circuit fault: Check whether the electronic thermostat connector is loose. If there is no loose connection, use a multimeter to measure the resistance of the electronic thermostat. If the resistance is infinite, it indicates an internal open circuit in the electronic thermostat, and the thermostat should be replaced.
