Why Does the Car Air Conditioner Emit a Burnt Smell When Heating?

What happens if the catalytic converter is removed from a car?

The vehicle will lose its ability to purify harmful gases such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx) from the exhaust emissions, resulting in significantly increased environmental pollution. Below is relevant information about catalytic converters: 1. Function: The catalytic converter is installed in the front section of the vehicle's exhaust pipe and is used to reduce toxic and harmful substances in the exhaust emissions. 2. Structure: The exterior of the catalytic converter is made of double-layer stainless steel plates forming a cylindrical shape. Between the double-layer thin plates, there is an insulating material—asbestos fiber felt. Inside, a purifying agent is placed between mesh partitions. The purifying agent consists of a carrier and a catalyst.

What are the 6 things to do when you get a new car?

Here are the 6 things to do when you get a new car: 1. Remove the protective film: New vehicles usually come with a protective film to prevent scratches, but it should be removed upon delivery because the film contains harmful gases that can be detrimental to human health. For your safety, it's best to remove the film right away. 2. Check the included items: Ensure all the items that come with the vehicle are complete, such as the warning triangle, tire-changing tools, etc. If anything is missing, ask the dealer to provide it immediately. 3. Inspect the vehicle's basic condition: Check if the tire pressure is normal and if all the displays inside the car are functioning properly. These checks can prevent future maintenance issues, so be thorough and don't miss anything. 4. Ventilate the car: Air out the interior to remove any odors. Since the car has been in the dealership for a while, the air inside may have become stale and could contain harmful gases. 5. Adjust the seats: Set up the driver's seat and rearview mirrors to your preference at the dealership, so you won't be flustered when driving home. 6. Familiarize yourself with the car's functions: Different cars have different features, so getting to know them beforehand will make driving much easier.

What Causes Engine Shaking in a New Car?

The causes of engine shaking in a new car include an inappropriate air-fuel mixture ratio in the engine compartment, poor fuel quality, and faults in the electronic control system. Here are some additional details: 1. Precautions for driving a new car: Maintain smooth starts, avoid sudden acceleration, and do not let the engine speed get too high. Before starting, ensure the water temperature reaches at least 50 degrees Celsius. Start in a low gear and shift to a higher gear after driving 1 kilometer. Shift gears promptly while driving, avoiding prolonged use of a single gear. Do not use a high gear for low-speed driving or a low gear for high-speed driving. 2. Choose good road conditions: Select smooth roads to minimize excessive vibrations and impacts. Before braking, disengage the clutch first. Use high-quality fuel and engine oil, and avoid using engine wear-resistant additives.

When to Use the Car's Internal and External Air Circulation?

Internal air circulation means only the air inside the vehicle is recirculated, while external air circulation allows fresh air from outside to enter the vehicle. Below is a detailed introduction: 1. Introduction: Internal circulation recirculates the air inside the car, driven by the blower. External circulation connects the interior with the outside air. The internal circulation symbol displayed on the screen indicates the car is currently in internal circulation mode. Pressing the internal circulation button again while it is active will turn it off, switching the car to external circulation mode. 2. Applicable Scenarios: Use internal circulation during traffic jams; switch to external circulation for long highway drives.

What is the best location to install an in-car ETC?

For small cars, the ETC is generally installed in the upper middle part of the front windshield, while for large vehicles such as trucks and buses, the installation position is in the lower middle part. The suitable installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 and 90 degrees. If the vehicle has an anti-explosion film or if one is installed later, it may affect the signal transmission of the microwave communication link, and the ETC should be installed in the microwave skylight zone. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for it, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle registration certificate. If someone other than the owner is handling the application, they also need to bring their own valid ID card. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is required, and the vehicle must be registered under the name of an individual aged between 18 and 60. Here are some precautions for installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have a large rearward tilt angle of the windshield, which can reduce the driver's field of vision. If this is not considered during ETC installation, it may increase the driver's blind spots. Installing it behind the rearview mirror on the right side can help avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and positions that may block the solar panel. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After the electronic tag is installed, the windshield will press the anti-removal lever in. If the tag is removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. In such cases, you will need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle ahead to avoid automatic toll payment for the front vehicle. The recognition speed for ETC lanes is 20 kilometers per hour. Driving too fast may result in failure to read the vehicle's device information, leading to failed toll deductions. When using a debit card linked to ETC, insufficient balance may also cause toll deduction failures.

What Are the Basic Knowledge Points About Auto Loans?

Auto loans refer to car mortgage loans. Below is the relevant introduction: 1. Overview: A car mortgage loan is a loan obtained from financial institutions or auto consumer loan companies by using the borrower's or a third party's car or self-purchased car as collateral. The primary purpose of using a car as collateral is for quick capital turnover. (Due to rapid car depreciation and the high probability of traffic accidents affecting vehicle value, financial institutions relatively rarely issue loans using cars as the sole collateral. Generally, the loan evaluation is 50-80% of the car's value.) 2. Relevant regulations: Article 22 of the "Motor Vehicle Registration Regulations" clearly stipulates that if a motor vehicle owner uses the vehicle as collateral, they must apply for mortgage registration at the local vehicle management office. The application requires presenting the motor vehicle registration certificate, the identity proofs of the mortgagee and the mortgagor, and filling out the "Motor Vehicle Mortgage/Cancellation Mortgage Registration Application Form."
