What is inside a three-way catalytic converter?

A three-way catalytic converter consists of four main components: the shell, vibration damping layer, substrate, and catalyst coating. The specific details about the three-way catalytic converter are as follows: 1. Metals contained in the three-way catalytic converter: Platinum is one of the metals found in automotive three-way catalytic converters. Other metals include cerium, copper, iron, manganese, nickel, palladium, and rhodium. The content of these metals varies depending on the vehicle model and production batch. However, the content of platinum, palladium, and rhodium determines the recycling value of the automotive three-way catalytic converter. 2. The three-way catalytic converter is a crucial external purification device in the automotive exhaust system: It converts harmful gases such as CO, HC, and NOx from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Since the three-way catalytic converter can simultaneously convert the three main harmful substances in exhaust gases into harmless substances, it is called 'three-way.' 3. Working principle of the three-way catalytic converter: When high-temperature vehicle exhaust passes through the purification device, the catalyst in the three-way catalytic converter enhances the activity of CO, HC, and NOx gases, promoting specific oxidation-reduction chemical reactions. This process transforms the three harmful gases into harmless ones, thereby purifying the vehicle exhaust.

What to Do When the Car Interior Temperature is High?

When the car interior temperature is high, the specific solutions are as follows: 1. Continuously open and close the car doors: Quickly replace the hot air inside the car through air exchange by first opening the passenger-side door, then opening and closing the driver-side door 5 to 10 times to release the hot air inside. 2. Replace with a spare ventilated seat cushion: After getting out of the car, place the cushion in a cooler spot inside the car. When you get back in, using the cushion placed earlier will separate you from the original hot cushion, helping to lower the interior temperature. 3. Use physical cooling methods: Prepare a cooling spray by mixing alcohol with water in a ratio of 1 (alcohol) to 10 (water). After mixing, pour it into a spray bottle. When using, open the car doors and windows, then spray the mixture around the car interior. After one minute, the temperature inside the car will noticeably drop. 4. Turn on the car air conditioning's cooling mode: Activating the car air conditioning's cooling mode will blow cold air, helping to cool down the interior faster.

What does the violation code 60230 mean?

The violation code 60230 means: Driving a motor vehicle on roads other than expressways or urban expressways without following the designated lane. According to the relevant provisions of the "Road Traffic Safety Law of the People's Republic of China," the penalty is: 0 demerit points; fine amount: 50 yuan; other penalties: none. Traffic violation codes consist of four to five digits, classified according to the principles in the traffic law. The order from left to right is: the first digit represents the behavior classification code, the second digit represents the demerit point classification code, the third and fourth digits are sequential codes, and the fifth digit indicates the item number. First digit: Behavior classification code, indicating the category in the Road Traffic Law; Second digit: Demerit point classification code, indicating the classification of demerit points for traffic violations; Third, fourth, and fifth digits: Sequential code, indicating the order of the behavior within the same classification. For example, 13035—"1" indicates motor vehicle behavior, the second digit "3" means 3 demerit points, and "035" indicates the fifth item under the third category of 3-point violations. Behavior classification code explanation: Codes starting with "1" indicate motor vehicle traffic, e.g., 1003; Codes starting with "2" indicate non-motor vehicle traffic, e.g., 2002; Codes starting with "3" indicate pedestrian or passenger traffic, e.g., 3030; Codes starting with "4" indicate expressway traffic, e.g., 4002; Codes starting with "5" indicate other regulations, e.g., 5005; Codes starting with "7" indicate provincial, autonomous region, or municipal implementation rules, e.g., 7008; Codes starting with "8" indicate local regulations of cities (prefectures, autonomous prefectures, or leagues), e.g., 8606. There are four common ways to check motor vehicle violations: Visit the office halls of traffic police departments in various districts or counties to inquire via touch-screen terminals; Log in to the public service website of the local Public Security Bureau's Traffic Management Bureau, find the vehicle violation inquiry section, enter the license plate number and engine number, and click "Query"; Call the inquiry hotline (area code + 114); Use the Traffic Management 12123 app (V2.8.1B437 for iOS 15+ or V2.8.1B274 for Android 12+) to check. For the violation of driving a motor vehicle on roads other than expressways or urban expressways without following the designated lane, you can handle it through the Traffic Management 12123 app. After logging in, enter the violation processing workflow, complete the process, and make the payment.

Where Are the Clutch and Accelerator Located?

Here is a detailed introduction to the positions of the car clutch and accelerator: 1. Introduction to the positions of the clutch and accelerator in manual and automatic transmission cars: Manual transmission cars have three pedals, arranged from left to right as the clutch, brake, and accelerator. Automatic transmission cars have only two pedals, arranged from left to right as the brake and accelerator, and do not have a clutch. 2. Function of the car clutch: During driving, the driver can press or release the clutch pedal as needed to temporarily separate or gradually engage the engine and transmission, thereby cutting off or transmitting the engine's power to the transmission. The clutch ensures smooth starting or seamless gear shifting. 3. Function of the car accelerator: By controlling the amount of pedal depression, the throttle opening is adjusted to regulate the air intake. The computer then controls the fuel injection, thereby controlling the engine's speed. 4. Function of the car brake: The brake is used to decelerate or bring the vehicle to a stop.

Is It Normal for the Steering Wheel to Become Heavier After Replacing the Steering Gear?

It is not normal for the steering wheel to become heavier after replacing the steering gear. This could be due to contaminated power steering fluid, insufficient tire pressure, and other factors that may cause the steering wheel to feel heavier. Below is more information about the steering gear: 1. The automobile steering gear, also known as the steering mechanism or steering box, is the most important component in the car's steering system. Its function is to amplify the force transmitted from the steering wheel to the steering linkage and to change the direction of the force. 2. Commonly used steering gears include rack and pinion, worm and roller, and recirculating ball types. The rack and pinion steering gear is the most common type, with its basic structure consisting of a pair of meshing pinion and rack gears. The worm and roller steering gear uses a worm as the driving part and a roller as the driven part. The recirculating ball power steering system mainly consists of mechanical and hydraulic parts.

What does it mean when the driver alert system is activated?

The activation of the driver alert system indicates an abnormality in the exhaust emission control system, meaning the emissions fail to meet the China VI standards. The driver alert system is an alarm system set up in diesel vehicles to comply with the China VI emission standards. Its purpose is to ensure the exhaust emission control system operates normally, especially the urea system, to guarantee that nitrogen oxide emissions meet the standards. The activation of the driver alert system typically corresponds to six major types of faults: urea level fault; urea quality fault; urea injection system interruption; urea consumption deviation fault; EGR valve sticking; fault detection due to tampering. Handling methods for driver alert system activation: Urea level fault, urea quality fault, urea injection system interruption, and urea consumption deviation fault are all caused by the urea system not functioning properly. The urea system should be cleaned and refilled with an appropriate amount of urea as soon as possible. EGR valve sticking: The EGR system should be promptly cleared to ensure smooth operation. Eliminating the driver alert system light usually requires professional repair at a service station. Fault detection due to tampering: If the fault is caused by tampered data, the vehicle's diagnostic computer should be used to reset the system, restoring the driver alert system data to normal. If the driver warning system light is not addressed in time, the driver alert system will limit the engine's performance output. The driver alert system includes a two-stage engine performance limitation logic: the first-stage engine performance limitation system and the second-stage engine performance limitation system. Triggering the first-stage limitation system reduces the engine's maximum torque to about 75%; triggering the second-stage limitation system limits the engine performance to only allow the vehicle to drive at a speed of 20 mph.
