What is a Three-Way Catalytic Converter Made of?

The exterior of a three-way catalytic converter is constructed with double-layer stainless steel sheets formed into a cylindrical shape. Between the double-layer sheets, there is an insulating material—asbestos fiber felt. Inside, a purifying agent is placed within the mesh partitions. Below is relevant information about the three-way catalytic converter: 1. The three-way catalytic converter is the most important external purification device installed in a vehicle's exhaust system. 2. It converts harmful gases such as CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. 3. It features stable performance, reliable quality, and a long lifespan, making it widely suitable for models from Toyota, Honda, Buick, Audi, Volkswagen, Hyundai, Suzuki, Changhe, and others. 4. The three-way catalytic converter is used to purify exhaust gases, reducing pollutants in the emissions, which benefits environmental protection. It is installed on the exhaust pipe of every vehicle.

Can Antifreeze from Different Brands Be Mixed?

Antifreeze from different brands cannot be used together. The production formulas of antifreeze vary by brand, and mixing them may cause chemical reactions between the various additives, leading to their ineffectiveness. Antifreeze Replacement Cycle: Vehicle antifreeze generally needs to be replaced every 2 years or 40,000 kilometers. This is just a reference period. For commercial vehicles with higher mileage, the replacement cycle should be shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Check the antifreeze's condition—if it is insufficient, replenish it promptly. If suspended particles, sediment, or signs of deterioration or discoloration are observed, replace the antifreeze and clean the system immediately. What Is Antifreeze? The full name of antifreeze should be antifreeze coolant, meaning a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head during cold winter parking.

Can the car still be driven if the water temperature rises while driving?

Continuing to drive when the water temperature rises can easily damage the engine, and in severe cases, major repairs may be required. The reasons for the increase in water temperature are as follows: 1. Insufficient coolant: Coolant leakage or insufficient coolant can cause the engine water temperature to rise. 2. Cooling fan failure: When the vehicle is running at high speed, the heat generated cannot be transferred to the antifreeze in time, affecting heat dissipation, which then leads to an increase in the temperature of the antifreeze, causing boiling and other issues. 3. Circulation water pump failure: Pump failures include bearing seizure and impeller damage. Bearing seizure is relatively rare, while impeller damage commonly involves impeller cracking or the impeller loosening from the pump shaft, leading to slower coolant circulation and easily causing engine overheating. 4. Thermostat failure: The thermostat automatically adjusts the amount of water entering the radiator based on the coolant temperature, changing the water circulation range to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within the appropriate temperature range. If the thermostat fails, the car's cooling system may not perform a large circulation, leading to an increase in water temperature. 5. Poor radiator heat dissipation: Using water as a medium for a long time can cause rust in the engine and radiator, leading to poor radiator heat dissipation and high water temperature.

What does it mean when a Land Rover displays 'tailgate open'?

When a Land Rover displays 'tailgate open', it indicates that the vehicle's tailgate is open. If the tailgate is open while driving, you should slow down and stop when it is safe to do so, and then close the tailgate. Additional information about Land Rover is as follows: 1. Land Rover uses two types of engines, one is a low-power version of the 2.0-liter turbocharged engine; the other is a high-power version of the 2.0-liter turbocharged engine. 2. The low-power version of the 2.0-liter turbocharged engine has 200 horsepower and a maximum torque of 320 Nm, with the maximum torque available between 1200 and 4000 rpm. 3. The high-power version of the 2.0-liter turbocharged engine has 249 horsepower and a maximum torque of 365 Nm, with the maximum torque available between 1300 and 4500 rpm.

How to Operate the Brakes After a Vehicle Has Waded Through Water?

Methods for operating the brakes after a vehicle has waded through water are as follows: 1. When wading through water, use a low gear to enter the water smoothly. Avoid shifting gears, stopping, or making sharp turns while driving. If wheel spin is detected, stop immediately. 2. While driving, focus on a fixed target and avoid looking at the water flow to prevent visual interference and deviation from the driving route. 3. For multiple vehicles wading through water, do not enter the water simultaneously. Wait for the preceding vehicle to cross before the following vehicles proceed in sequence. 4. For vehicles with four-wheel drive, engage the front drive wheels when wading to increase driving force. 5. After wading, perform inspections: remove any coverings, dry the damp parts, reinstall the fan belt, and restore the battery and muffler to their original positions. 6. Drive in a low gear and gently press the brake pedal. Once the braking performance returns to normal, accelerate and continue driving.

How to Drive When Visibility is Less Than 100 Meters on the Highway?

When driving on the highway with visibility less than 100 meters, the speed should not exceed 40 kilometers per hour, and a distance of more than 50 meters should be maintained from the vehicle ahead. Here are the relevant guidelines regarding visibility: 1. If visibility is less than 50 meters, the speed should not exceed 20 kilometers per hour, and you should exit the highway via the nearest exit as soon as possible. 2. If visibility is less than 200 meters, the speed should not exceed 60 kilometers per hour, and a distance of more than 100 meters should be maintained from the vehicle ahead. Precautions for highway driving: 1. Entering the driving lane correctly: When entering the highway from an on-ramp, the vehicle must accelerate in the acceleration lane and turn on the left turn signal. Only when it does not affect the normal driving of vehicles in the main lane should it merge into the driving lane from the acceleration lane, and then turn off the signal. 2. Maintaining a safe distance: When driving at high speed, the following vehicle in the same lane must maintain a sufficient safe distance from the vehicle ahead. A rule of thumb is that the safe distance is approximately equal to the speed in meters. For example, at 100 km/h, the safe distance is 100 meters; at 70 km/h, it is 70 meters. In adverse weather conditions such as rain, snow, or fog, the distance should be increased, and the speed should be appropriately reduced. 3. Overtaking cautiously: When overtaking, first observe the status of the vehicles ahead and behind, then turn on the left turn signal. After confirming it is safe, slowly turn the steering wheel to the left to smoothly enter the overtaking lane. After overtaking the vehicle, turn on the right turn signal. Once the overtaken vehicle is fully visible in the rearview mirror, smoothly steer back into the right driving lane and turn off the signal. Avoid sudden steering during overtaking. 4. Proper use of brakes: Emergency braking on the highway is very dangerous. As speed increases, the tire's grip on the road decreases, increasing the likelihood of braking deviation or skidding, making it difficult to control the vehicle's direction. Additionally, if the following vehicle cannot react in time, it may lead to a multi-vehicle collision.
