What Causes High Pressure in Car AC Without Cooling?

What brand are BMW spark plugs?

BMW spark plugs are of the Bosch brand. Spark plugs are a crucial component of the gasoline engine ignition system. They introduce high-voltage electricity into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Working principle of spark plugs: The ground electrode of the spark plug is connected to the metal shell, which is threaded into the engine block via the cylinder head. The insulator primarily serves to isolate the metal shell from the central electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and the central electrode, it breaks down the medium between the central electrode and the ground electrode to generate a spark, thus igniting the air-fuel mixture in the cylinder. Location of spark plugs: Spark plugs are installed on the side or top of the engine. In earlier designs, spark plugs were connected to the distributor via ignition cables. However, over the past decade, most car engines have transitioned to direct connection between the ignition coil and the spark plug.

How to Switch Modes on the Mercedes-Benz GLC?

Mercedes-Benz GLC driving mode switching method is as follows: Simply use the "small mouse" in the central control area or the multifunction buttons on the steering wheel to locate the "Driving Mode" option in the vehicle's computer system while the car is running, and you can make the switch. The Mercedes-Benz GLC offers four driving modes: Eco mode, Comfort mode, Sport mode, and Sport+ mode. Below are the details of each mode: 1. When the car is in Eco mode, the throttle response slows down, reducing the vehicle's power output to achieve fuel efficiency. 2. In Comfort mode, the car's transmission and throttle response are balanced, with moderately firm suspension settings, providing a comfortable driving experience. 3. In Sport mode, the car's chassis becomes firmer, the transmission and throttle response speeds up, and gear shifts occur later to deliver higher power. 4. In Sport+ mode, the car's chassis is at its firmest, enhancing stability during high-speed cornering. Additionally, the throttle pedal becomes more responsive, and the transmission keeps the engine in a higher RPM range to maximize the vehicle's power output.

What is the tire model of the Hyundai Elantra?

The Hyundai Elantra 1.6L is equipped with Nexen Npriz AH8 series tires, with specifications 205/55/R16. These tires prioritize comfort and grip for daily driving. Here is some relevant information about tire pressure: 1. Both overinflation and underinflation can affect tire lifespan. In winter, tire pressure can be slightly higher than in summer. Recommended summer tire pressure is between 2.2-2.5 bar, while winter pressure should not exceed 2.8 bar. Adjust pressure appropriately based on load conditions. 2. Insufficient tire pressure may lead to excessive wear, poor vehicle control, reduced fuel efficiency, and potential wheel deformation. Therefore, maintain tire pressure within the specified range. 3. Excessive tire pressure can result in uncomfortable rides, accelerated wear in the center tread, and increased risk of tire damage on hazardous road surfaces.

Do You Need to Press the AC Button to Turn on the Cold Air?

The AC button in a car activates the air conditioning compressor. To use the air conditioning for cooling, you need to press the AC button. When pressed, the air conditioning compressor starts working to blow cool air into the car. Below are some methods for maintaining your car's air conditioning system: 1. Comprehensive inspection of the air conditioning system. When using the air conditioning for the first time in summer, you should first inspect the system. For example, check the refrigerant level through the reservoir and see if the air filter is dirty or if there are any foreign objects in the radiator. 2. Pay attention to cleaning the air conditioning. The air filter should be replaced regularly because spring brings a lot of dust and willow catkins, which can stick to the filter and promote bacterial growth, leading to a musty smell in the air conditioning. Additionally, the condenser should be cleaned periodically, and the radiator should be removed for thorough cleaning. 3. Regularly turn on the high fan setting. The air conditioning system can accumulate a lot of dust during use. Turning on the high fan setting periodically helps blow out dust from the air ducts, which is a simple way to keep the air conditioning clean. Also, use specialized duct cleaning solutions.

Where are the license plates starting with 'Yun' from?

Yun is the abbreviation for Yunnan, so license plates starting with 'Yun' are from Yunnan. The license plates of each province in China start with the abbreviation of the province. More information about Yunnan license plates is as follows: 1. Yun A: Kunming City, Yun C: Zhaotong, Yun D: Qujing, Yun E: Chuxiong, Yun F: Yuxi, Yun G: Honghe, Yun H: Wenshan, Yun J: Simao, Yun K: Xishuangbanna, Yun L: Dali, Yun M: Baoshan, Yun N: Dehong, Yun P: Lijiang, Yun Q: Nujiang, Yun R: Diqing, Yun S: Lincang. 2. Yun O-U are license plates of the Yunnan Provincial Public Security Department. This is because Yun O followed by five digits are license plates for provincial-level party and government institutions in Yunnan, and those with the first digit of the five-digit number being A-S are license plates for public security, procuratorial, and judicial departments in various cities and prefectures of Yunnan. The Provincial Public Security Department wanted a dedicated number segment, so they used the 'U' prefix.

When will the Lynk & Co 05 be released?

Lynk & Co 05 was released on May 5, 2020. Here is some relevant information about the Lynk & Co 05: 1. Interior: The new car adopts a brand-new design language, differing from the multi-arc rounded-corner interior design of existing products. The Lynk & Co 05 extensively employs straight lines and diamond-shaped lines, creating a good sense of layering. However, at first glance, there is a noticeable sense of patchwork, especially as the large central touchscreen appears somewhat too "isolated." In terms of materials, the new car uses a lot of suede and red stitching. 2. Powertrain: The new car will be equipped with a 1.5T turbocharged engine (model JLH-3G15TD) and a 2.0T turbocharged engine (model JLH-4G20TD), with maximum power outputs of 180 horsepower and 190 horsepower, respectively. Additionally, the car is expected to feature a high-power 2.0TD engine from Volvo's Drive-E series in the future, with a maximum power of 254 horsepower and a peak torque of 350 N·m. In terms of transmission, it will be paired with an Aisin 8-speed automatic transmission, and a four-wheel-drive version will also be available.
