Can vehicle inspection be done on Saturdays?

Vehicle inspection can be done on Saturdays. Can vehicle inspection be done on Saturdays: According to Article 15 of the "Opinions on Strengthening and Improving Motor Vehicle Inspection Work": inspection institutions should implement an uninterrupted system on Saturdays, Sundays, and holidays, providing extended inspection services. Article 16 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" stipulates: for mini and small non-commercial passenger vehicles, vehicles within 6 years should be inspected every 2 years based on the motor vehicle registration date; vehicles over 6 years need annual inspection; vehicles over 15 years require inspection every 6 months. Documents required for vehicle annual inspection: Required documents: vehicle license, compulsory motor vehicle traffic accident liability insurance (copy), inspector's ID card, triangular warning sign, fire extinguisher. (Vehicle violations must be handled, and no modifications are allowed on the vehicle body).

Is Pulling Up the Handbrake Considered Parking?

Pulling up the handbrake is considered parking. Handbrake: The handbrake uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. Prolonged use of the handbrake can cause plastic deformation of the cable. Since this deformation is irreversible, long-term use will reduce its effectiveness and increase the handbrake's travel distance. Handbrake Precautions: Starting and driving without fully releasing the handbrake will significantly accelerate the wear of the handbrake mechanism. Consistently operating in this manner can cause irreversible damage to the handbrake. Therefore, it is essential to develop the habit of checking whether the handbrake is fully released before starting. During high-speed driving, directly pulling the handbrake is extremely dangerous. The handbrake primarily acts on the rear wheels, and pulling it abruptly can cause the rear wheels to lock up, leading to skidding or even a rollover. The correct approach is to downshift to reduce speed and only engage the handbrake when the vehicle speed is very low to bring the car to a complete stop.

What is the fuel consumption of a new Mazda Axela?

The 'metal-on-metal' squealing sound indicates that the brake pads must be replaced immediately. The fuel consumption of a new Mazda Axela is 7.4L/100km. Here is an introduction to the fuel consumption of a new Mazda Axela: 1. Fuel consumption: The fuel consumption is 7.4L/100km. 2. Precautions: New cars have a break-in period. Due to machining precision and assembly tolerances during manufacturing, new cars tend to consume more fuel and feel underpowered during the break-in period. These issues will significantly improve after the first oil change. The vehicle's driving conditions, mileage, driving habits, and load also directly affect fuel consumption. The same car can have a fuel consumption difference of several liters, with urban and suburban driving conditions potentially doubling the difference, and short trips versus long-distance driving potentially differing by 1-2 times.

What Causes Steering Wheel Vibration at Speeds Over 120 km/h?

Steering wheel vibration issue at speeds exceeding 120 km/h. Causes of steering wheel vibration at speeds over 120 km/h: This may indicate poor dynamic balance of the two front wheels, which can be adjusted. A car's wheel is an integrated unit composed of the tire and rim. However, due to manufacturing tolerances, mass distribution across this unit cannot be perfectly uniform. When the wheels rotate at high speeds, this creates dynamic imbalance, resulting in wheel vibration and steering wheel shaking during driving. Inspection for steering wheel vibration at speeds over 120 km/h: Check whether the tread contact surfaces (especially front tires) contain large stones or other foreign objects; verify whether tire pressure differences between coaxial or cross-axle tires are excessive; determine if wheel dynamic balance precision inspection and weight distribution were properly performed after wheel/tire replacement or tire repair (excessive dynamic balance deviation can cause vibration). If none of these three factors are problematic, inspect whether four-wheel alignment precision exceeds tolerance when necessary.

What is the issue with the DC-DC failure in new energy vehicles?

The issue with the DC-DC failure in new energy vehicles. No output from the DC-DC controller: Troubleshooting methods: No high-voltage (DC72V-DC86V) input or no 12V start signal voltage input, as well as a fault in the DC-DC converter itself, can all cause the DC-DC controller to have no output voltage. Measure whether there is high-voltage input at the DC-DC input terminal. If there is no 12V start signal voltage input, it indicates a fault in the main circuit, and further inspection of the continuity of the line between the main signal connector terminal and the constant power battery positive terminal is required. Low output voltage from the DC-DC. Troubleshooting methods: If the DC-DC controller itself is faulty, replace it with a new one. The steps for troubleshooting abnormal DC-DC operation are as follows: first, measure whether there is voltage input; second, measure whether there is a 12V signal voltage input; and third, measure whether there is voltage output.

What Causes a Car to Misfire?

Car misfiring is caused by clogged fuel injectors; faulty spark plugs, ignition coils, and cylinder wires. Clogged Fuel Injectors: After prolonged use, fuel injectors may become clogged, leading to issues such as altered spray patterns, delayed solenoid valve operation, or excessive fuel injection. This can result in an overly rich air-fuel mixture, causing symptoms like backfiring and engine shaking. If a single injector is clogged, it may also cause intermittent misfiring and car vibration. Faulty Spark Plugs: Spark plugs are well-known wear-and-tear components with a limited lifespan. For example, standard copper-core spark plugs last about 30,000 kilometers, platinum spark plugs can last up to 80,000 kilometers, and iridium spark plugs may last 100,000 kilometers with proper use. However, even if a spark plug hasn't reached its expected lifespan, it can still fail and cause misfiring. Faulty Ignition Coils and Cylinder Wires: Each cylinder's spark plug is connected to an ignition coil and cylinder wire. If these components fail, the spark plug won't fire, and the cylinder won't operate, resulting in misfiring symptoms.
