Why is the car battery not charging while driving?

Car battery not charging while driving reasons are as follows: Deep discharge: The car battery not charging is most likely due to deep discharge, meaning when the vehicle is turned off, the car's equipment inside remains in a working state, continuously consuming the battery's power. Over time, this will definitely accelerate the battery's degradation, leading to a situation where the battery doesn't hold charge anymore. Generator belt aging: Another reason could be the aging of the generator belt. It's important to know that the engine directly drives the generator through the belt, and the electricity generated is then rectified and voltage-regulated before directly charging the car battery. Therefore, if the belt malfunctions, it naturally leads to a failure in charging, necessitating timely replacement.

What is the emission standard for cars manufactured in 2009?

2009 cars are either China III or China IV emission standard. Vehicles produced between July 2007 and September 2009 comply with China III standard, while those manufactured after September 2009 generally meet China IV standard. Here are methods to check your vehicle's emission standard: 1. Environmental label: Check the back of the car's environmental compliance label to easily identify the emission standard. 2. Vehicle certificate: The first page of the vehicle qualification certificate contains emission standard information, though not directly stated as "China X" but rather in coded characters. 3. Manufacturing date: You can roughly estimate the emission standard based on the vehicle's production year. 4. DMV: Bring your vehicle registration certificate (original or copy) to the local Department of Motor Vehicles for verification.

Is the DLH engine an EA888?

No, the DLH is a German-made engine. Below is relevant information about the EA888: 1. Concept: The 'Volkswagen EA888 engine' is a newly designed engine by Volkswagen, integrating advanced technologies such as direct fuel injection, turbocharging, and variable valve timing, achieving a balance between power and fuel efficiency. 2. System: The fuel supply system is the most critical part of achieving direct fuel injection. To inject fuel into the high-pressure cylinders, sufficient injection pressure is required. The high-pressure fuel pump is a key component in pressurizing the fuel. The EA888 engine's fuel pump is a simple single-plunger pump, driven by a square (four-point) cam on the intake camshaft. The four-point cam ensures synchronization between the fuel pump's supply stroke and the corresponding injection process of each cylinder, resulting in better uniformity and repeatability of fuel injection across cylinders.

Can New Energy Vehicles Get Blue License Plates?

New energy vehicles cannot be registered with blue license plates. Below is relevant information about license plate registration for new energy vehicles: Regulations: According to the national regulations on new energy vehicle license plates, if a motor vehicle is classified as a new energy vehicle, based on its attributes, only new energy license plates can be issued during registration, transfer, and other registration procedures. Blue license plates cannot be issued. For new energy vehicles already registered with blue license plates, they may continue using the blue plates or choose to apply for replacement with new energy vehicle license plates. Introduction to New Energy Vehicles: New energy vehicles refer to automobiles that use unconventional vehicle fuels as power sources or conventional vehicle fuels with new types of onboard power devices, integrating advanced technologies in vehicle power control and driving systems. These vehicles feature advanced technical principles and incorporate new technologies and structures. New energy vehicles include hybrid electric vehicles, fuel cell electric vehicles, pure electric vehicles, and other types of new energy vehicles.

What is the reason for the constant illumination of the brake lights on the new Mondeo?

Ford Mondeo brake lights remain illuminated for the following reasons: 1. Insufficient brake fluid: Brake fluid is an essential component of the vehicle's braking system. When the driver presses the brake pedal, the force applied is transmitted by the piston in the master cylinder through the brake fluid to the wheel cylinders at each wheel, causing the brake pads to contact the wheels and stop the vehicle. 2. Brake switch: Check if the brake switch has poor contact or fails to reset after loosening. Inspect the brake wiring for poor contact or short circuits. Examine the brake pedal pad and check if the brake rubber ring is severely worn or if the brake switch is damaged (the switch is located above the pedal). Replace the brake pedal pad or the brake switch as needed. 3. Worn brake pads: If the brake pads are severely worn, the light may stay on continuously, requiring replacement of the brake pads.

Why is it difficult to shift into first gear?

Reasons for difficulty in shifting into first gear: 1. Low vehicle temperature, transmission oil not fully lubricated. 2. Difficulty shifting into first gear while moving, speed and gear position mismatch. 3. First gear and reverse gear lack synchronizers. Method to test if first gear is faulty: It is recommended to attempt shifting into reverse gear when the vehicle is stationary. If the transmission makes a "clicking" gear collision sound during the reverse gear engagement process, it indicates that the vehicle's clutch is not fully disengaged. After repairing the clutch, the fault can be eliminated. If reverse gear engages smoothly but only first gear is difficult to shift into, it is recommended to visit a specialized repair shop to adjust the gear shift position and replace the transmission oil, which can also resolve the issue. For manual transmissions, shifting at low speeds requires the clutch to be able to fully disengage in order to smoothly engage the corresponding gear.

When will the 10th-generation Accord meet China VI emission standards?

The 10th-generation Accord does not meet China VI emission standards; its emission standard is China V. According to the emission standard information for the 10th-generation Accord displayed on GAC Honda's official website, it complies with China V standards. The release date for China VI standards depends on the manufacturer's arrangements. Here is some additional information: 1. Introduction: China VI standards generally refer to the National Sixth Stage Emission Standards for Motor Vehicles. 2. Categories: The 'National Sixth Stage Emission Standards for Motor Vehicles' consist of two parts: 'Limits and Measurement Methods for Emissions from Light-duty Vehicles (China VI)' and 'Limits and Measurement Methods for Emissions from Heavy-duty Diesel Vehicles (China VI)'. These standards were established to implement the 'Environmental Protection Law of the People's Republic of China' and the 'Air Pollution Prevention and Control Law of the People's Republic of China', aiming to prevent pollution from exhaust emissions of compression-ignition and gas-fueled ignition engine vehicles, protect the ecological environment, and safeguard human health.
