The three-way catalytic converter in a car refers to the most important external purification device installed in the vehicle's exhaust system. It converts harmful gases such as CO, HC, and NOx emitted from the vehicle's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. The introduction and structure of the three-way catalytic converter are as follows: Introduction to the three-way catalytic converter: The three-way catalytic converter is the most important external purification device installed in a vehicle's exhaust system. It converts harmful gases such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx) emitted from the vehicle's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Because this converter can simultaneously transform the three main harmful substances in exhaust gases into harmless substances, it is called a three-way catalytic converter. Structure of the three-way catalytic converter: Structure: The three-way catalytic reactor is similar to a muffler. The outer shell is made of double-layered stainless steel plates formed into a cylindrical shape. Between the double-layered plates, there is insulation material—asbestos fiber felt. Inside, there is a purifying agent placed between mesh partitions.

How to Distinguish Between 92 and 95 Gasoline?

92 and 95 gasoline can be distinguished in the following aspects: 1. Composition of 92 and 95: 92 gasoline consists of 92% isooctane and 8% n-heptane, while 95 gasoline is composed of 95% isooctane and 5% n-heptane. The reason 95 gasoline is slightly more expensive is due to its higher proportion of isooctane. Isooctane also has another function, which is anti-knock. This means the higher the proportion of isooctane, the better the anti-knock performance. Each engine is given a comprehensive evaluation before leaving the factory, and based on the engine's performance and other data characteristics, the anti-knock requirement is specified, which determines the grade of gasoline to be used. 2. Price difference between 92 and 95: A tank of 95 gasoline is slightly more expensive than a tank of 92 gasoline. By subtracting the price of 92 gasoline from that of 95 gasoline and then multiplying by 8, you can obtain the price difference per 100 kilometers of car fuel consumption. 3. Power of 92 and 95: 95 gasoline with a higher octane rating is suitable for engines with higher compression ratios. This is because as the operating speed of such engines increases, the ignition timing in the cylinder will advance more and more. When the speed reaches a critical point, the air-fuel mixture in the cylinder may ignite prematurely before the spark plug fires, a phenomenon known as "knocking." Increasing the octane rating of gasoline can effectively enhance anti-knock performance.

Difference Between Dual-Piston Calipers and Single-Piston Calipers?

The difference between dual-piston calipers and single-piston calipers lies in their design approaches. Here are the specific details: Single-piston calipers, commonly found in mass-market vehicles, typically feature a unidirectional piston configuration. The brake pad on the opposite side is pushed by the reaction force of the caliper, hence earning the name "floating caliper." In contrast, dual-piston calipers have both inner and outer sides fixed, with each side's brake pad clamping force managed by separate pistons, thus referred to as "fixed calipers." When comparing single-piston calipers to multi-piston calipers, single-piston designs often leave unused space that cannot be filled. To minimize the caliper body's size and maximize piston area, dual-piston calipers were developed. Most single/dual calipers on the market are floating calipers (also called unidirectional floating calipers). True multi-piston calipers, however, are fixed brake calipers (also known as fixed opposed-piston calipers). Floating brake calipers generally have brake pistons only on one side. When the piston presses the friction pad against the brake disc, only one side makes contact initially. As hydraulic pressure peaks, the piston can no longer extend outward, creating a reaction force that moves the entire caliper, bringing the opposite friction pad into contact with the disc. When both pads engage, full braking force is achieved. Thus, the floating caliper's key feature is its ability to shift laterally, ensuring both friction pads contribute to braking. Opposed-piston calipers, on the other hand, feature pistons on both sides that simultaneously push the friction pads against the brake disc to generate braking force. This design necessitates a fixed caliper position during operation.

Can You Continue Driving When the Car's Oil Light Comes On?

When the car's oil light comes on, you should not continue driving. It is necessary to pull over and conduct a thorough inspection or repair of the vehicle before continuing. The purpose of the oil warning light is to alert the driver that the engine's oil level is low and needs to be replenished as soon as possible to avoid affecting the engine's normal operation. In severe cases, it may cause the engine to seize. Below are the steps to address the issue when the oil light comes on: 1. Stop the vehicle immediately and wait for 5-10 minutes before carefully opening the hood (do not open it immediately after stopping to avoid burns). 2. Check the oil level. If it shows that the oil level is low, you need to add oil. If you do not have spare oil, pull over immediately and contact rescue services if the engine starts shaking or the noise increases. 3. After adding oil, restart the vehicle to see if the oil light still comes on. If the light does not come on, it indicates that the issue was caused by low oil level, which is not a major problem. 4. Although you can continue driving, it is strongly recommended to visit a 4S shop or repair station as soon as possible to determine the cause of the oil consumption. 5. If the oil level is within the acceptable range, you should safely pull over and contact a 4S shop rescue vehicle for immediate repairs. The warning light may be caused by damaged oil system components or abnormal pressure. Continuing to drive may worsen the issue and even lead to engine failure.

Can You Still Drive After Reaching the Car Maintenance Mileage?

After reaching the maintenance period, the car can continue to be driven if there is no damage to the body components, as there is no regulation prohibiting driving after the maintenance period has expired. Vehicle maintenance is the best way to extend the lifespan of a car. If the maintenance mileage is reached, it is recommended to visit a 4S shop for maintenance. Below are the classifications of maintenance levels: 1. Primary maintenance (around 5,000 kilometers): Maintenance operations centered on tightening and lubrication for vehicles that have traveled a certain mileage. This includes inspecting and tightening the exposed bolts and nuts of the car; adding lubricant to the designated lubrication points; checking the oil level in each assembly and adding lubricating oil; cleaning various air filters, etc. 2. Secondary maintenance (around 10,000 kilometers): Maintenance operations centered on inspection and adjustment for vehicles that have traveled a certain mileage. The scope of maintenance, in addition to the tasks of primary maintenance, includes checking and adjusting the working condition of the engine and electrical equipment, dismantling and cleaning the oil pan and oil filter, checking and adjusting the steering and braking mechanisms, dismantling and cleaning the front and rear hub bearings. Adding lubricating oil, dismantling and inspecting tires, and performing tire rotation, etc. 3. Tertiary maintenance (around 20,000 kilometers): Maintenance operations centered on disassembling, cleaning, inspecting, adjusting, and eliminating hidden dangers for the vehicle assemblies. The scope of maintenance: In addition to performing all the tasks of primary and secondary maintenance, it is necessary to dismantle and inspect the engine, remove carbon deposits, gum, and dirt from the cooling system; disassemble, clean, inspect, adjust, and eliminate hidden dangers for the chassis assemblies; inspect the frame and body or perform rust removal and touch-up painting.

What Causes Motorcycle Turn Signals Not to Work?

Motorcycle turn signals not working are generally due to a flasher relay failure. Below are specific details about motorcycle turn signals: 1. Function of Turn Signals: As a main component of the signal system, motorcycle turn signals primarily serve to alert others of the vehicle's turning intention. After completing a turn, the turn signals must be manually turned off. 2. Steering Method: Mechanically, motorcycles require minimal steering movement. The steering mechanism involves slight handlebar rotation, and even at maximum handlebar angle, the turning radius remains small. Motorcycles rely more on body lean and handlebar push to complete turns.
