In which year did China's National IV emission standard come into effect?

China's National IV emission standard was implemented in 2011 and remained in effect until the introduction of the National V standard in 2018. Therefore, vehicles produced between 2011 and 2017 comply with the National IV standard. The National IV standard requires a reduction of approximately 50% in various pollutant emissions compared to the National III standard. Here are some relevant details: 1. National IV Standard: The National IV emission standard is the fourth stage of China's motor vehicle pollutant emission standards. The main pollutants from vehicle emissions include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), and PM (particulate matter). The standard aims to control and reduce these emissions below specified limits through technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices. 2. Reference for Emission Standards: The frequent updates to emission standards are due to the increasing number of vehicles, which has led to worsening environmental pollution from vehicle exhaust. Vehicle exhaust contains harmful gases such as carbon monoxide and hydrocarbons, and the emission standards set limits on the discharge of these gases. China's emission standards are primarily based on European Union standards, with some adaptive modifications made to suit local conditions.

What are the rules for Subject 2 driving test?

Subject 2 driving test rules are as follows: 1. Reverse parking into garage: Driving not according to the prescribed route sequence (fail), vehicle body crossing the line (fail), failing to park in the garage (fail); Before reversing, if both front wheels' contact points do not exceed the control line (fail), completion time exceeding 210 seconds (fail), stopping for more than 2 seconds during the process (deduct 5 points per time). 2. Hill start and stop: After the vehicle stops, if the front bumper is not aligned with the pole line and exceeds 50cm (fail), does not exceed 50cm (deduct 10 points); After stopping, if the start time exceeds 30 seconds (fail), wheels pressing the road edge line while driving (fail), vehicle rolling back more than 30cm during start (fail); After the vehicle stops, if the body is more than 50cm away from the road edge line (fail), if the parking brake is not tightened after stopping (deduct 10 points per time), if the body is between 30cm and 50cm away from the road edge line after stopping (deduct 10 points per time), if the vehicle rolls back between 10cm and 30cm during start (deduct 5 points per time).

Why doesn't the headlight washer retract on the Audi A6?

The reason why the headlight washer does not retract on the Audi A6 is that the washer fluid inside the spray piston has frozen. Taking the 2021 Audi A6 as an example, its body dimensions are: length 4951mm, width 1886mm, height 1483mm, wheelbase 2925mm, fuel tank capacity 73l, and trunk capacity 565 to 1680l. The 2021 Audi A6 features front and rear five-link independent suspension, equipped with a 2.0T turbocharged engine and a 7-speed dual-clutch transmission, delivering a maximum horsepower of 190PS, maximum power of 140kW, and maximum torque of 320Nm.

What Happens If a Vehicle Fails to Undergo Annual Inspection?

Motor vehicles are required to undergo an initial inspection within the first two years after registration and licensing, followed by an annual inspection thereafter. Failure to comply will result in the vehicle being prohibited from road use. According to relevant authorities at the Vehicle Management Office, under the "Mandatory Scrapping Standards for Motor Vehicles" implemented on May 1st of this year, registered vehicles that fail to obtain an inspection compliance mark for three consecutive inspection cycles after the expiration of their inspection validity period will be forcibly deregistered. Vehicles that have not undergone the required inspection will be captured by electronic surveillance if driven on the road and may be intercepted and impounded by traffic police. Regulations for vehicle annual inspections: 1. Consequences of failing inspection for 3 years: Registered vehicles that fail to obtain an inspection compliance mark for three consecutive inspection cycles after the expiration of their inspection validity period will be forcibly scrapped and deregistered. 2. Micro non-commercial passenger vehicles: Small and micro non-commercial passenger vehicles must be inspected once every two years within the first six years; once annually after six years; and twice annually after 15 years. 3. Commercial passenger vehicles: Commercial passenger vehicles must be inspected once annually within the first five years; once every six months after five years. 4. Trucks: Trucks and large or medium-sized non-commercial passenger vehicles must be inspected once annually within the first ten years; once every six months after ten years.

What Are the Causes of Cabin Resonance Humming?

The causes of cabin resonance humming are: 1. Resonance caused by engine mounts, leading to noise; 2. Noise generated by the front part of the engine, generator bearings, pump bearings, or compressor bearings; 3. Aging engine mounts causing resonance, which need replacement. Methods for engine maintenance include: 1. Using qualified engine oil; 2. Using qualified coolant and antifreeze; 3. Regularly cleaning radiator scale; 4. Regularly removing engine carbon deposits; 5. Regularly replacing the car's three filters; 6. Maintaining reasonable RPM. The function of the engine is to convert thermal energy into mechanical energy by expanding gas after combustion in a sealed cylinder, pushing the piston to do work, thereby providing power for the vehicle.

Why does the tire pressure monitoring light come on when it's too cold?

When the tire pressure monitoring light comes on in cold weather, it's due to low tire pressure. The functions of tire pressure monitoring are: 1. Preventing accidents; 2. Extending tire service life; 3. Reducing wear on the suspension system. Tire pressure monitoring automatically checks tire pressure in real-time while driving and alerts the driver to leaks or low pressure to ensure driving safety. The working principle of tire pressure monitoring involves a built-in sensor in the tire's hub, which includes a bridge-type electronic pressure sensing device that detects pressure, converts the pressure signal into an electrical signal, and transmits it wirelessly.
