Prado 4.0 has 2 catalytic converters. Working principle of catalytic converters: When high-temperature automobile exhaust passes through the purification device, the filter in the catalytic converter enhances the activity of CO, HC, and NOx gases, promoting their reduction chemical reactions. CO oxidizes at high temperatures into colorless, non-toxic carbon dioxide gas; HC compounds oxidize into water and carbon dioxide at high temperatures, and NOx reduces into nitrogen and oxygen. The three harmful gases are transformed into harmless gases, thereby purifying the automobile exhaust. Appearance of catalytic converters: Its exterior is made of double-layer stainless steel sheets formed into a cylindrical shape. The interlayer is filled with insulating material, asbestos fiber felt. Inside, a specialized filtration and purification device is installed between the mesh partitions.

Traffic police do check demon eyes. Here are specific details about demon eyes: 1. Color: Demon eye headlights are purple or blue. After modifying such headlights, traffic police will definitely check them when driving on the road. Do not modify vehicle lights casually as it is illegal. 2. Name: Demon eyes resemble the eyes of a car, with the lens acting as the eyeball. Inside the lens, a colored light is illuminated, causing the entire lens to change color. 3. Brightness: Demon eyes are not very bright and do not cause confusion with police or special operation vehicles. They do not flash and will not be mistaken for vehicle turn signals. Located at the front of the vehicle, they will not be confused with brake lights. The distance between two demon eyes is more than 80 centimeters, meeting the minimum spacing requirement for vehicle left and right lights.

Will unpaid traffic fines prevent the reset of driver's license points?

If there are unpaid fines for traffic violations, the demerit points on the driver's license will not be reset. More information about the driver's license point reset is as follows: 1. Cycle: The accumulation period for road traffic violation points (i.e., the scoring cycle) is 12 months, with a maximum of 12 points, calculated from the date the driver's license was initially issued; 2. Duration: One scoring cycle = initial license issuance date + 12 months. For example: If the license was first issued on August 11, then the scoring cycle runs from 00:00:00 on August 11 to 23:59:59 on August 10 of the following year, and the system automatically performs the point reset on August 11; 3. Notes: The system determines whether fines have been paid based on bank records. Payers should settle fines in advance to avoid delays in point reset.

How to Solve the Front Wheel Brake Lock-up Issue in Cruze?

There are three methods to solve the front wheel brake lock-up issue in Cruze: forced start, tire removal, or brake master cylinder cup blockage. Below are the reasons for tire lock-up: 1. Absence of ABS anti-lock braking system: For vehicles without an ABS anti-lock braking system, it is easy to experience lock-up during emergency braking. This happens because, during sudden braking, the braking force exceeds the friction between the tires and the ground, leading to tire lock-up. In severe cases, this can cause skidding or even rollover. 2. Vehicle parked for an extended period leading to lock-up: Especially for vehicles that have been through water and then parked for a long time, lock-up is most likely to occur. When the brake pads and drum brakes stick together, they are prone to rust, causing tire lock-up. In such cases, sandpaper can be used to polish and alleviate the lock-up phenomenon.

How to Solve Fogging Inside the Car?

There are several methods to deal with fogging inside the car, which are: 1. When the fogging is not severe, you can appropriately open both windows to allow air convection. 2. Turn on the air conditioning cold air, which can eliminate fogging in a very short time. 3. Turn on the air conditioning cold and hot air, which can fundamentally solve the problem of glass fogging. 4. Use anti-fog spray, spraying a layer on the windshield to form an effective protective film, thereby preventing the condensation of water vapor. Here are some additional introductions: For some high-end brands, vehicles are equipped with functions to prevent fogging. The air conditioning system in these models constantly monitors the temperature and humidity inside the car and analyzes the critical temperature for water vapor condensation at the moment based on these two indicators. By comparison, it can determine whether the air inside the car will fog up on the front windshield.

What is the correct sequence for removing a car battery?

The correct sequence for removing a car battery is: 1. Park the car on a level surface and turn off the engine to cut power; 2. Use a screwdriver to remove the battery cover; 3. Disconnect the battery cables, ensuring to remove the negative terminal first, followed by the positive terminal; 4. Remove the battery securing bracket; 5. Install the new battery in reverse order, making sure to connect the positive terminal first, then the negative terminal when reattaching the cables. A car battery, also known as an automotive battery, is primarily used for starting the engine, powering vehicle lighting, audio systems, and other electronic components. If the battery is depleted or malfunctions, it can affect the car's ability to start normally. During routine maintenance, it's important to periodically charge the battery. Additionally, the car should be started periodically, and after turning off the engine, avoid using electronic devices to preserve battery life.

Functions of Car Central Door Locks?

The main functions of car central door locks are as follows: First: Central control. When the driver locks the door beside them, all other doors are simultaneously locked. The driver can open all doors at once using the door lock switch or open a single door individually. Second: Speed control. When the vehicle reaches a certain speed, all doors automatically lock to prevent passengers from accidentally opening the door by operating the door handle. Third: Individual control. In addition to the door beside the driver, other doors are equipped with separate spring lock switches, allowing independent control of opening and locking a single door. Below is additional information about car central door locks: The central door lock ECU consists of components such as an input device, memory, discriminator, encoder, driver stage, anti-interference circuit, display device, safety device, and power supply. The electronic central door lock system offers various functions, including door lock control, door unlock control, key reminder prevention, and trunk door opener control.
