Biofuel vehicles are primarily classified into ethanol fuel and biodiesel. Below are the roles and application methods of biofuels: Roles of biofuels: Bioethanol fuel has become one of the world's recognized environmentally friendly fuels and a major resource to replace fossil fuels. It can substitute gasoline and diesel derived from petroleum, representing an important direction for the development and utilization of renewable energy. Application methods of biofuels: The first is the blending method, where ethanol is mixed with gasoline. Since this method does not require significant technical modifications to the internal combustion engine or major vehicle components, it is the primary approach for the promotion and application of ethanol vehicles. The second is the pure burning method, where ethanol is used as the main vehicle fuel (E85 or above). The third is denatured fuel ethanol, which refers to ethanol that is dehydrated and then mixed with a denaturant. Vehicles using denatured fuel ethanol are still in the experimental application stage.

When I used to help people with their cars at the dealership, I encountered biofuel vehicles mainly categorized into several types. The most common classification is based on the fuel used: ethanol vehicles, such as E85 fuel vehicles, which use a mixture of 85% ethanol and 15% gasoline; biodiesel vehicles, which use diesel refined from vegetable oil or animal fat; and biogas-powered vehicles, suitable for farms or waste treatment facilities. Each type requires special attention to engine compatibility, such as biodiesel vehicles being prone to clogging filters, and ethanol vehicles needing careful handling of moisture issues. For maintenance, I would advise owners to regularly check the fuel system to avoid fuel expiration or adulteration. Overall, categorizing by fuel source is easy to remember and practical, and it helps in choosing the best solution based on usage scenarios.

As an average car driver, I've tried several types of biofuel vehicles and found they can be roughly categorized into three types. First are bioethanol vehicles, which use ethanol fuel made from corn or sugarcane; second are biodiesel vehicles that run directly on vegetable oil-based diesel; and third are biogas vehicles powered by methane from landfills or anaerobic digestion. For example, I've driven a Flex-Fuel car that can blend ethanol with gasoline, offering great flexibility. Biodiesel vehicles are more common in trucks and are durable for long-distance travel. The advantage of these vehicles is their environmental friendliness, reducing carbon emissions, but the instability of fuel supply is a pain point. When choosing, consider local infrastructure to ensure you don't use the wrong fuel and damage the engine. Daily maintenance is simpler, just pay more attention to fuel quality.

The classification of biofuel vehicles is quite straightforward, categorized by fuel type into ethanol-based, biodiesel-based, and biogas-based. Ethanol vehicles, such as E10 cars, contain 10% ethanol; biodiesel vehicles can use pure vegetable oil-based diesel; biogas vehicles are suitable for large vehicles like buses. Flex-Fuel technology enables vehicles to mix fuels, accommodating different biofuels. The benefits include being eco-friendly, but compatibility must be noted to avoid using the wrong fuel. During use, regular maintenance ensures system smoothness and prevents clogging from impurities.

Precautions for Car Purchase and Selection

The most important considerations when purchasing and selecting a car are the vehicle's price, followed by its quality, appearance, and purchase policies. Below is an introduction to the precautions for picking up a car: Inspecting the Vehicle Condition: Park the vehicle in an outdoor area with ample light to examine the body paint. Ensure there are no scratches or wear on the paint, that the paint is even, and that it appears translucent under sunlight reflection. Open the car door—the vehicle's identification plate is located near the driver's side door or B-pillar—and check the relevant information on the plate. Open the engine compartment to inspect if it is clean, free of dirt or dust buildup, and check if the engine oil and other fluids are at adequate levels. Manually test if the doors open and close smoothly, if the windows roll up and down properly, if there is any strong odor inside the car, if the air conditioning cools effectively, if the windshield wipers function correctly, and if all lights illuminate properly. Test Driving: Start the engine to assess whether the idle is smooth, if there is noticeable noise inside the car, and if the steering wheel vibrates significantly. Checking Documents: Verify that all relevant vehicle documents are complete, such as the purchase invoice, certificate of conformity, vehicle type approval certificate, vehicle registration certificate, warranty certificate, vehicle user manual, and new car delivery confirmation form.

How to Enter an Unmanned Parking Lot with Temporary License Plates?

Temporary license plates can enter parking lots, but it requires manual operation by the toll collector. Some parking lot scanners may not recognize them, in which case entry is not possible unless manually opened. However, if there is no manual record, parking time cannot be calculated, and no fee will be charged. Additional information about temporary license plates for vehicles is as follows: Definition: Temporary license plates for vehicles refer to temporary driving permits issued by the vehicle management department of the public security bureau before the vehicle is officially registered due to pending formalities. Application Process: The applicant must present a letter of introduction from their organization, proof of vehicle origin, certificate of compliance, and other relevant documents (except for the letter of introduction, which is archived, the rest are returned to the applicant) to the vehicle management office. During the application, the applicant must specify the starting and ending locations of the vehicle's travel and the duration of temporary license plate use. After review by the management personnel and inspection of the vehicle, a temporary license plate will be issued, along with the validity period and travel locations.

What are the correct steps to use BMW's electronic parking brake?

When pulling the parking brake, the buckle on the brake head will bounce back and forth due to the spring inside exerting force, which helps prolong the service life of both the spring and the small buckle. Do not yank the parking brake up abruptly when engaging it, as this can damage the brake over time. The correct method is to pull the parking brake up gently and smoothly. There is no difference in the braking effect between pulling the parking brake up 100% and 70%. Frequently pulling the parking brake to its highest point will shorten the lifespan of the brake cable.

How to Read the Pressure Gauge on a Car Air Conditioning System?

There are two pressure gauges in a car air conditioning system: the red one is the high-pressure gauge, and the blue one is the low-pressure gauge. Under normal operating conditions, the low-pressure gauge should read between 1.0~2.5 bar, and the high-pressure gauge should read between 15~18 bar. If the low-pressure reading is higher or lower than this range, it indicates an issue with the expansion valve adjustment or the compressor's performance. The car air conditioning pressure gauge is used to diagnose the refrigeration system. If the gauge readings deviate from the normal values, it suggests a potential fault in the refrigeration system: When the car air conditioning pressure gauge shows low low-pressure and low high-pressure: This may indicate insufficient refrigerant, which is a common issue. In older cars, refrigerant leakage can occur, and refilling the refrigerant after inspection can resolve the problem. When the car air conditioning pressure gauge shows high low-pressure and high high-pressure: This may indicate a stuck-open expansion valve. Poor cooling performance coupled with high readings on both gauges suggests the expansion valve is stuck open, allowing air to enter the system and mix with the refrigerant, reducing cooling efficiency. Replacing the expansion valve can fix the issue. When the car air conditioning pressure gauge shows vacuum low-pressure and low high-pressure: This may indicate a stuck-closed expansion valve. If the car is not cooling at all, the evaporator expansion valve is likely stuck closed, and replacing the expansion valve is necessary. 4. When the car air conditioning pressure gauge shows fluctuating low-pressure (sometimes normal, sometimes vacuum) and fluctuating high-pressure (sometimes normal, sometimes low): This may indicate moisture in the refrigeration system. When moisture freezes in the pipes, it causes the low-pressure side to show a vacuum. Once the ice melts, the system returns to normal. To fix this, the refrigerant must be drained, the system evacuated, and new refrigerant added. 5. When the car air conditioning pressure gauge shows high low-pressure and low high-pressure: This may indicate a compressor fault. If the gauges show these readings despite sufficient refrigerant, and the cooling performance is poor, the issue likely lies with the compressor, which may have internal leaks. Replacing the compressor usually resolves the problem.
