What Causes Black Smoke from Diesel Vehicles?

The main reasons for black smoke from diesel vehicles are as follows: 1. Wear of piston rings, cylinder liners, etc. Wear of valves, piston rings, and cylinder liners leads to insufficient compression pressure and oil entering the combustion chamber, altering the normal air-fuel mixture ratio at the end of the compression stroke. This causes fuel to burn under oxygen-deficient conditions, leading to carbon deposits during combustion and the emission of large amounts of black smoke. 2. Changes in combustion chamber shape. Due to manufacturing quality and long-term use, the technical condition of the combustion chamber deteriorates, resulting in excessive or insufficient compression clearance or incorrect piston positioning. These changes affect the combustion chamber's shape and volume, impairing the quality of the air-fuel mixture and worsening combustion conditions. 3. Poor injector performance. 4. Excessive fuel supply. An oversupply of fuel increases the amount of oil entering the cylinder, creating a fuel-rich and air-lean condition that leads to incomplete combustion. Additionally, excessive workload, low-quality fuel, and low operating temperatures can also cause black smoke emissions. 5. Incorrect adjustment of the fuel injection timing. If the injection timing is too advanced, fuel is injected into the combustion chamber too early. Since the pressure and temperature in the cylinder are still low at this point, the fuel cannot ignite. When the piston moves upward and the cylinder reaches sufficient pressure and temperature, the combustible mixture burns.

What are the types of traffic violations that result in 12-point deductions?

There are eleven types of traffic violations that result in a 12-point deduction: 1. Driving a motor vehicle that does not match the permitted vehicle type; 2. Driving under the influence of alcohol; 3. Operating a passenger transport vehicle (excluding buses) or school bus with more than 20% over the permitted passenger capacity; 4. Fleeing the scene of a traffic accident without constituting a crime; 5. Driving a motor vehicle on the road without displaying a license plate, or intentionally obscuring, damaging, or improperly installing the license plate; 6. Using forged or altered motor vehicle license plates, driving licenses, school bus permits, or using other vehicles' license plates or driving licenses; 7. Driving a motor vehicle in reverse, against traffic, or making a U-turn across the central divider on a highway; 8. Parking a passenger transport vehicle in a highway lane; 9. Driving medium-sized or larger passenger or cargo vehicles, school buses, or hazardous material transport vehicles exceeding the speed limit by more than 20% on highways or urban expressways, or exceeding the speed limit by more than 50% on other roads, or driving other motor vehicles exceeding the speed limit by more than 50%; 10. Driving medium-sized or larger passenger vehicles or hazardous material transport vehicles for more than 4 hours without stopping for a break, or stopping for less than 20 minutes; 11. Driving a school bus without the proper qualifications.

Why Did the Car Battery Suddenly Run Out of Power?

There are several reasons why a car battery may suddenly run out of power: 1. Prolonged vehicle inactivity: When a car is left unused for an extended period, the battery's charge gradually depletes. After long periods of inactivity, the battery may become drained, making it impossible to start the car. Additionally, if the headlights are left on overnight after parking, the battery may also lose its charge. 2. Battery reaching the end of its lifespan: Car batteries have a limited lifespan. If not replaced after prolonged use, they may fail. The condition of the battery can be determined by observing the color indicator inside: green indicates normal operation, black signifies low voltage, and white means the battery has reached the end of its life and needs replacement. 3. Engine damage: If the car engine's belt becomes loose or breaks, it cannot drive the generator, leading to an open circuit. Broken generator wires or loose connections can also cause the battery to discharge without recharging. 4. Insufficient battery electrolyte: When the car battery's electrolyte level is low, the battery cannot hold a sufficient charge. Over time, the electrolyte evaporates, so it's essential to regularly check its level, which should be between the maximum and minimum marks. 5. Corroded battery terminals: With prolonged use, the battery terminals may corrode, leading to power loss. It's important to inspect the battery regularly, clean any corrosion, and prevent abnormalities that could disrupt normal vehicle operation.

What is the best gear to leave the car in when idling for a long time?

When idling for a long time, manual transmission cars can be shifted into neutral (N) with the handbrake engaged, while automatic transmission vehicles can either be shifted into neutral (N) or park (P) with the handbrake firmly applied. Below is additional information about car gear selection: 1. Automatic transmission vehicles have both P (Park) and N (Neutral) gears, both of which can be used when parking, but they serve different purposes. 2. The P gear includes a locking mechanism, whereas the N gear does not. When shifted into P, the locking mechanism inside the transmission locks the gear, effectively securing the wheels. In this position, even without engaging the handbrake, the car will not roll. In contrast, shifting into N does not lock the transmission gear, meaning the car could roll if the handbrake is not applied. 3. For short stops like waiting at a red light without turning off the engine, using N gear is appropriate. However, when parking and turning off the engine, shifting into P gear is mandatory. Some vehicles will not allow the key to be removed unless shifted into P after turning off the engine, while others require shifting into P before the engine can be turned off—this is a safety feature. It is advisable not to shift into P while waiting at a red light. If the car is rear-ended while in P, the transmission could be damaged. Always ensure the car is completely stationary before shifting into P.

Generally, this tax is listed on the same document as the compulsory insurance. In Shenzhen, since 2009, vehicle and vessel tax must be paid together when purchasing compulsory insurance. ID card and photocopy of ID card; For company vehicles, the company code certificate and the agent's identity proof are required. Basic process for vehicle annual inspection: Fill out two forms: the Motor Vehicle License Application Form and the Motor Vehicle Inspection Record Form; Go to the annual inspection registration window to have materials reviewed and recorded. Visit the violation inquiry window. If there are any violations, pay the fines here; Proceed to the vehicle inspector for an external inspection. Open the hood for the inspector to check the chassis number. The inspector will provide a signed inspection approval page. Then, go to the inspection fee payment window to receive the invoice. Go to the inspection registration window and leave all materials there; Wait in line for the inspection. After the inspection, you will receive an inspection report; Submit the annual inspection materials to the staff; Upon passing the inspection, the annual inspection sticker will be issued.
