What Causes Weak Airflow in a Car's Air Conditioning System?

Weak airflow in a car's air conditioning system can be attributed to the following reasons: Incorrect Airflow Direction Setting: If the air conditioning is set to blow towards the windshield or side windows, the airflow into the cabin may feel significantly weaker. Blower Motor Malfunction: Short circuits or reduced power in the blower motor can naturally decrease the air volume delivered by the car's air conditioning. If the issue lies with the blower motor, it is advisable for car owners to seek professional assistance from a 4S store or a specialized repair shop rather than attempting DIY repairs. Dirty Cabin Air Filter: A heavily soiled air filter can obstruct the airflow. The cabin air filter is designed to remove impurities from the air entering the cabin. Excessive accumulation of these impurities can impede the airflow from the vents.

Do new energy vehicles require tax payment for license plate registration?

New energy vehicles do not require tax payment for license plate registration. Eligibility criteria: Pure electric vehicles, plug-in (including range-extended) hybrid vehicles, and fuel cell vehicles that are approved for sale in China. The power batteries used do not include lead-acid batteries. The comprehensive fuel consumption of plug-in hybrid passenger vehicles (excluding fuel consumption converted from electricity) must be less than 60% of the corresponding target value in the current national standard for conventional fuel consumption. The comprehensive fuel consumption of plug-in hybrid commercial vehicles (excluding fuel consumption converted from electricity) must be less than 60% of the corresponding limit value in the current national standard for conventional fuel consumption. The vehicles must pass the special inspection for new energy vehicles and meet the requirements of new energy vehicle standards. New energy vehicles: New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of on-board power devices), integrating advanced technologies in vehicle power control and drive systems, resulting in advanced technical principles and featuring new technologies and new structures.

Why Is There Abnormal Noise from the Rear Drum Brakes?

Abnormal noise from the rear drum brakes is caused by either the brake shoe friction lining being worn out or uneven tension between the left and right brake shoes. Concept of Drum Brakes: Drum brakes utilize stationary brake shoes inside the brake drum to create friction against the rotating drum, thereby reducing the wheel's speed. When the brake pedal is pressed, the force applied by the foot pushes the piston in the master cylinder, which in turn pressurizes the brake fluid in the hydraulic lines. This pressure is transmitted to the wheel cylinders at each wheel, where the pistons push the brake shoes outward, causing them to rub against the inner surface of the brake drum. This friction generates sufficient resistance to slow down the wheel, achieving the braking effect. Causes and Solutions for Abnormal Noise: 1. Oil or grease contamination between the brake shoes and the drum can cause slipping and produce a sharp noise. Solution: Clean the brake drum and shoes with alcohol to remove the contamination. 2. If the surface of the brake shoes is too smooth, it can also lead to slipping and sharp noise. Solution: Use 800-grit sandpaper to roughen the surface of the brake shoes to increase friction.

Is it allowed to change lanes to the right?

Changing lanes to the right is not allowed, as it violates the prohibition of crossing solid line markings. Below are some techniques for changing lanes to the right: Check the distance on both sides: Keep your car within the two white lines and avoid crossing them. If you are not changing lanes, you generally don't need to check the rearview mirror and can drive normally without worrying about vehicles overtaking from behind. Additionally, look farther ahead and not just in front of your car. Turn on the turn signal before changing lanes: When changing lanes, activate the turn signal in advance. The turn signal is crucial as it informs the vehicles behind that you intend to turn, prompting them to slow down naturally. Check the rearview mirror promptly: After turning on the turn signal, immediately check the rearview mirror and then gradually change lanes in the desired direction. When changing lanes to the right, focus on the right-side rearview mirror. At the same time, check for any pedestrians or vehicles ahead to ensure a safe lane change.

Can a Tianjin automobile be converted from manual to automatic transmission?

Tianjin automobile can be converted from manual to automatic transmission. Manual and automatic models of the same vehicle can be interchanged: They share the same production platform, with most components being identical except for the transmission. This makes it possible to replace a manual transmission with an automatic one, including achieving good compatibility with screws, engine mounts, and other fixed positions. High costs are involved in transmission replacement: Switching from a manual to an automatic transmission requires purchasing a new automatic transmission, and the cost of replacing the transmission increases significantly due to the need to discard the old one. Converting a manual transmission car to an automatic one involves numerous issues: Not only does it require replacing the vehicle's transmission, but it also involves rewiring, power matching, ECU parameter tuning, and other challenges. The operation is highly complex, and any minor issue in the process can affect the vehicle's performance.
