What does automotive NVH mean?

NVH stands for Noise, Vibration, and Harshness. Here is some relevant information: 1. NVH issues are ubiquitous and can be categorized into three main areas based on their sources: engine NVH, body NVH, and chassis NVH. Further subdivisions include aerodynamic NVH, air conditioning system NVH, road driving NVH, braking system NVH, etc. 2. Harshness, also known as unevenness or impact characteristics, is related to the transient nature of vibration and noise. It describes the subjective human perception of vibration and noise and cannot be directly measured by objective methods. The comfort experienced by vehicle occupants and the strength and lifespan issues of automotive components caused by vibration all fall within the scope of NVH research. From an NVH perspective, a car is a system composed of excitation sources (engine, transmission, etc.), vibration transmitters (consisting of suspension systems and connectors), and noise emitters (vehicle body). 3. NVH issues are systemic. For example, if a car's cabin noise is excessive while driving and the source is traced to the engine, this noise issue may involve three parts: the engine itself being noisy, poor vibration damping by the engine mounting components, and inadequate sound insulation technology in the cabin's front wall and floor. This illustrates how NVH problems are interrelated systemic issues.

How to Install the Air Filter for Corolla?

Here are the steps to install the air filter for Corolla: 1. Make sure the car is turned off. The air filter of Corolla is located inside the glove box, so first open the glove box. 2. There is a buckle on the right side of the glove box. Pinch it and pull the side lever outward to reveal the air filter. 3. Remove the old air filter and install the new one (with the black side facing up). Below are the functions of the air filter: (1) It ensures the filter fits tightly against the housing, preventing unfiltered air from entering the cabin. (2) It absorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., in the air, with strong and lasting moisture absorption. (3) It separates solid impurities such as dust, pollen, and abrasive particles in the air. (4) It keeps the cabin air clean and free from bacteria, creating a healthy environment; effectively separates solid impurities like dust, core powder, and abrasive particles in the air; effectively intercepts pollen, ensuring passengers do not have allergic reactions that could affect driving safety. (5) It prevents the car windows from fogging up, ensuring clear visibility for safe driving; provides fresh air to the cabin, preventing passengers from inhaling harmful gases and ensuring driving safety; effectively sterilizes and deodorizes.

Can the Subject 2 Test Be Cancelled During the Pandemic?

During the pandemic, the Subject 2 test can be cancelled. If an applicant needs to cancel a scheduled test after making an appointment on the [Traffic Management 12123] platform, they must submit the cancellation request before the application deadline for the test plan. If the appointment has already been successfully scheduled and the applicant is unable to attend the test, they must cancel the test at the vehicle management office at least one day in advance. If the scheduled test plan has not yet reached its deadline, the appointment can be cancelled through the [Traffic Management 12123] platform. However, if the test plan has already expired or the test appointment has been successfully scheduled, the cancellation must be processed at the vehicle management office, and it must be done no later than one day before the test date. Generally, appointments can be cancelled online before receiving the confirmation SMS. Consequences of Cancelling the Subject 2 Test Cancelling an appointment will reduce the number of online cancellations available. If the cancellation limit is reached, applicants must bring valid identification to the office for in-person cancellation. Additionally, the priority for rescheduling the Subject 2 test will be based on the time of cancellation, which may result in a significantly lower position in the queue. This can lead to a very low success rate in scheduling the Subject 2 test in the short term.

Will Insufficient Battery in Car Remote Affect Starting?

Insufficient battery in a car remote can affect starting. If the car key battery is low, it may fail to pair with the engine for recognition. Without successful pairing, ignition becomes impossible, preventing the vehicle from starting. Therefore, when the car key shows low battery, the battery should be replaced promptly to avoid disrupting normal travel. Methods to determine if the car key battery is running low: 1. The required remote control distance becomes shorter than before: A fully charged remote can typically operate at distances over 20 meters. As the remote's battery depletes over time, its operational range diminishes, gradually reducing to about 10 meters or even as little as 5 meters when extremely weak. 2. The indicator light does not illuminate or dims during remote operation: Most car keys feature a small indicator light to prevent accidental or incorrect button presses. Normally, pressing any button would cause this light to illuminate. 3. Intermittent malfunction of the car key: Sometimes the buttons work, and other times they don't, requiring multiple presses for a response. This is known as intermittent malfunction. There are two possible scenarios in such cases: either the car key is damaged, or its battery is insufficient.

Is it a traffic violation to enter a roundabout from a right-turn lane?

Points will be deducted. Article 51 of the "Regulations for the Implementation of the Road Traffic Safety Law" stipulates: When a motor vehicle passes through an intersection controlled by traffic signals, it shall proceed according to the following provisions: At an intersection with marked directional lanes, enter the directional lane according to the intended direction of travel. Additional information: Precautions for right turns: 1. Function of a single solid yellow line: Prohibits vehicles from crossing or driving over the line in both directions. Single solid yellow lines are generally marked on roads with only one lane in a single direction or one motor vehicle lane and one non-motor vehicle lane, or on sections where overtaking is prohibited due to other hazards. 2. Function of double solid yellow lines: Similar to single solid yellow lines, they also prohibit vehicles from crossing or driving over the line in both directions. Double solid yellow lines are generally marked on roads with two or more motor vehicle lanes in a single direction and without a physical central divider. 3. Yellow solid and dashed lines: Usually marked before and after bridges and at sections where U-turns are allowed, they also serve to separate lanes in both directions. Vehicles are prohibited from crossing or driving over the line on the side with the solid yellow line, while temporary crossing or turning is permitted on the side with the dashed line.

What is the minimum ground clearance of the Volkswagen Bora?

The minimum ground clearance of the Volkswagen Bora is 122mm. Minimum ground clearance refers to the distance between the lowest point of the vehicle (excluding the wheels) and the supporting surface when the car is fully loaded and stationary. It is used to characterize the vehicle's ability to pass over obstacles such as rocks and tree stumps without collision. Factors affecting the ground clearance of a car include ground flatness, tire pressure, and fuel level. Taking the 2021 Bora as an example, it is equipped with a 1.2T turbocharged engine, with a maximum horsepower of 116PS, a maximum power of 85kW, a maximum torque of 200Nm, and is paired with a 7-speed dual-clutch transmission.
