The A-pillars of a car refer to the vertical pillars on either side of the front windshield, while the B-pillars are the vertical pillars located between the front and rear doors, connecting the car's roof and chassis. In addition to the A-pillars and B-pillars, cars also have C-pillars, which connect the roof to the body. The C-pillars can also absorb some of the impact force during a collision, ensuring the safety of rear-seat passengers. When a collision occurs at the front of the car, the first part to absorb the impact is the crumple zone of the front longitudinal beams. The resulting impact force is then transmitted to the A-pillars, which bear the brunt of the force. Therefore, in car crash tests, whether the A-pillars deform is a crucial indicator.

Are There Subsidies for Plug-in Hybrids?

Plug-in hybrid models are only eligible for subsidies if their electric range exceeds 50 kilometers. Below is an introduction to the characteristics of plug-in hybrid vehicles: 1. As a second-generation derivative of hybrid vehicles, which are a combination of traditional fuel-powered cars and pure electric vehicles, plug-in hybrid electric vehicles (PHEVs) can ensure extended driving range. In addition to battery power, they utilize fuel as an 'auxiliary feature' to support long-distance travel for consumers. Beyond the advantage of extended range, PHEVs offer a driving feel based on traditional fuel-powered cars, making them an ideal choice for consumers who appreciate the driving experience of fuel-powered cars but also enjoy the low-noise operation of electric vehicles. 2. The body structure of plug-in hybrid vehicles is relatively complex. Combining features of both pure electric and fuel-powered cars, their configuration is more intricate, resulting in higher manufacturing costs compared to both pure electric and fuel-powered vehicles. This is one of the reasons why plug-in hybrid vehicles face challenges in achieving mass-market sales.

What are the reasons for the wiper not working on the new Sylphy?

New Sylphy wiper not working reasons are as follows: Blown fuse: When the wiper fuse of the vehicle is blown, the wiper will definitely not work properly. In this case, a new fuse needs to be replaced. Wiper switch damage: If the wiper switch is faulty or has poor contact, it will generally affect the normal use of the vehicle's wiper. In this case, the wiper switch needs to be inspected, and if damaged, it should be replaced immediately with a new wiper switch. Vehicle battery dead: If the vehicle battery is dead, not only will the wiper not work properly, but the vehicle's lighting system, horn, and multimedia entertainment system will generally not function normally. In this case, the vehicle battery needs to be charged immediately. If the battery needs to be replaced, it must be replaced with an original battery to avoid quality issues.

Is It Safe to Stay in a Car During a Thunderstorm?

It is safe to stay in a car during a thunderstorm. Reasoning: The metal body of a car acts as an equipotential surface, meaning the electrical potential of the person inside the car and the car itself is roughly equal. Therefore, when lightning strikes, no current will be conducted to the person inside the car, making it a very safe place during a thunderstorm. Precautions during a thunderstorm: Avoid handling flammable materials in open containers. Stay away from water and small boats. If you are traveling, remain inside the car, as it often serves as an excellent lightning shelter. If no shelter is available, avoid the tallest objects in the area. If the only nearby object is an isolated tree, the best protection is to crouch in the open, maintaining a distance from the tree that is at least twice its height.

What Causes Oil Emulsification in the Civic?

The causes of oil emulsification in the Civic are as follows: Prolonged low-temperature engine operation: For example, frequent stop-and-go driving or prolonged idling can result in lower engine temperatures, and low ambient temperatures are also a contributing factor. When the engine operates at low temperatures, the fuel injected into the cylinders may not burn completely, particularly the gasoline that adheres to the cylinder walls. This gasoline can flow down the cylinder walls into the crankcase and mix with the engine oil, leading to oil emulsification. Internal corrosion of the oil cooler: If the oil and coolant passages become interconnected, the mixing of antifreeze and engine oil can cause emulsification. During engine operation, high temperatures are generated, and the heat carried away by the oil is exchanged with the coolant to achieve cooling. If the oil cooler is damaged internally, antifreeze can leak into the oil passages, resulting in oil emulsification. The solution is to replace both the engine oil and the oil cooler.

How to Reset BMW Tire Pressure?

First, press and hold the SET button on the far right in front of the gear lever. If the tire pressure is normal, the warning light can be turned off; It can also be turned off through the setting function in the multifunction steering wheel; Use a computer detector to reset and turn it off. Strictly speaking, tire pressure refers to the pressure of the air inside the tire. The level of tire pressure plays a crucial role in the performance and power of the car. When the tire pressure warning light comes on, immediately stop at an appropriate location to check the pressure of all four tires. If there is no significant shift in the vehicle's focus, it can be ignored. After restarting the car, the tire pressure system can be reset; If the tire pressure warning light comes on again or does not turn off, drive to the nearest auto repair shop or 4S store for a comprehensive tire inspection.

What does 'Low' mean on an Audi air conditioner?

On the air conditioner, 'Low' indicates weak cooling, which is low-grade cooling; 'Med' represents medium-grade cooling, and 'High' denotes strong cooling, or high-grade cooling. These correspond to the operating states of the compressor fan, with the operating frequency generally increasing with the cooling intensity. Introduction to 'Low' on air conditioners: On the air conditioner, 'Low' signifies weak cooling, or low-grade cooling, while 'Med' indicates medium-grade cooling, and 'High' represents strong cooling, or high-grade cooling. This is similar to the 'High' setting on most air conditioners. Air conditioner indicators: These indicators are used on inverter air conditioners. When set to 'Low cool,' the compressor fan motor operates at a low frequency; when set to 'Med cool,' it operates at a medium frequency; and when set to 'High cool,' it operates at a high frequency, achieving the strongest cooling effect.
