What is the mat in front of the car called?

The mat placed in front of the car, below the windshield, is called a dashboard sunshade mat. It serves both decorative purposes and helps prevent glare from the dashboard. Below are the installation steps for the sunshade mat: 1. To ensure the rolled dashboard mat lies flat, first reverse-roll it and then unfold it. 2. Use a damp cloth and cleaning solution to remove any hard debris left on the dashboard. Then place the sunshade mat on the cleaned dashboard. 3. Attach the adhesive strips to the designated positions. 4. Next, affix the dashboard mat onto the adhesive strips, aligning it properly with sensor and air vent locations during installation. 5. To secure the installed dashboard mat more firmly, gently smooth it out towards both the driver's and passenger's sides with your hands.

How to Alternate Between High Beam and Low Beam Headlights?

Here are the specific steps to alternate between high beam and low beam headlights: 1. In low beam mode, lift the combination light switch upward to switch to high beam; release the manual combination switch to reset to low beam. 2. There is a combination light switch on the left side of the steering wheel. At night, rotating the combination switch one notch forward turns on the instrument panel lights, rotating another notch turns on the low beam, and continuing to rotate another notch turns on the high beam. Here are the precautions for using high beam and low beam headlights: 1. On roads without central isolation facilities or center lines, do not use high beams when meeting an oncoming vehicle within 150 meters. 2. Do not use high beams when meeting non-motorized vehicles on narrow bridges or narrow roads without central isolation facilities or center lines. 3. When overtaking at night, alternate between high and low beams to alert the vehicle ahead. 4. When driving at night without streetlights, poor lighting, or in low visibility conditions such as fog, rain, snow, or dust, do not use high beams when a following vehicle is driving close to the vehicle in front in the same direction.

How to Check the Emission Standard of a Motor Vehicle?

Here are the methods to check the emission standard of a motor vehicle: 1. Directly observe the vehicle's environmental protection label, which has clear markings on the back. 2. Log in to the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire. 3. Bring the original or a copy of the motor vehicle registration certificate to the vehicle management office for inquiry. 4. Differentiate based on the vehicle's registration year. Generally, vehicles registered after 2008 are China IV standard, while those registered in 2007 are China III standard. Here is more information about motor vehicle emission standards: 1. The main pollutants emitted by vehicles include hydrocarbons, nitrogen oxides, carbon monoxide, and PM particles. 2. Technologies such as catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices can be applied to control and reduce vehicle emissions to below the specified standards.

How to Shift Gears in an Automatic Transmission?

Here are the methods for shifting gears in an automatic transmission: 1. Shift into P (Park) when parking. 2. Shift into N (Neutral) when waiting at a traffic light. 3. Shift into D (Drive) when starting to move. 4. Shift into S (Sport) for overtaking or racing, which allows high-rev shifting and quickly increases torque. Here is the specific starting procedure for an automatic transmission: 1. Insert the key into the ignition lock, turn on the ignition switch, observe whether all instruments are functioning normally, and then start the engine. 2. If any instrument is not functioning properly, immediately turn off the engine and restart only after checking and resolving the issue. 3. Press the clutch pedal and shift the gear lever into the 1st gear position. 4. Turn on the left or right turn signal, sound the horn, and observe the front, sides, top, and rearview mirror for any obstacles before starting, paying special attention to safety.

Does Intake Air Temperature Affect Engine Power?

Intake air temperature does affect engine power. Here is the analysis of why intake air temperature affects engine power: 1. If the intake air temperature is too high, it will lead to reduced engine power and may also cause engine knocking. 2. Knocking is a highly detrimental abnormal combustion phenomenon in engines. When the piston moves upward to compress the air-fuel mixture, both the pressure and temperature of the mixture increase. If the mixture ignites before the spark plug fires, this is known as knocking. 3. During knocking, while the piston is moving upward, the burning air-fuel mixture pushes the piston downward, resulting in decreased engine power and increased fuel consumption. 4. Severe knocking can even cause connecting rod deformation and piston cracking. If this occurs, the repair costs would be extremely high. Therefore, to enhance power output, it is advisable to lower the intake air temperature.

What is the difference between a monocoque body and a body-on-frame structure?

Here are the main differences between monocoque body and body-on-frame structure: 1. The core of a body-on-frame structure is a component called the frame. The frame is usually composed of two longitudinal beams and several cross beams, running through the entire body, with high strength and torsional resistance. (1) Advantages: The frame absorbs some engine vibrations and road shocks, reducing interior noise and providing protection to the body. (2) Disadvantages: The frame is heavy and positioned high, raising the vehicle's center of gravity, which reduces stability at high speeds. The heavy frame also increases the vehicle's weight, leading to higher fuel consumption. 2. The characteristic of a monocoque body is the absence of a separate frame, with the entire body integrated into one unit. (1) Advantages: Vehicles with monocoque bodies are lighter, have a lower center of gravity, offer smoother handling, and consume less fuel. (2) Disadvantages: Due to the lack of a frame, when driving on uneven roads with uneven wheel forces, the body is more prone to deformation.
