What is the general speed limit on highways?

On the highways in mainland China, there are speed limits for motor vehicles. The general maximum speed is 120 km/h, and the minimum speed is 80 km/h. For special road sections and tunnels, the speed limit indicated on roadside signs should be followed. For novice drivers, maintaining a speed of 90-100 km/h is recommended for safety. Below are some precautions for driving on highways: 1. Safety check: Before getting on the highway, check for any potential safety hazards. It's essential to inspect your vehicle for any issues before driving on the highway. 2. Wear seat belts: Always wear seat belts in the front and rear seats, and avoid placing unsecured items in the vehicle. 3. Stay in one lane: Avoid frequent lane changes on the highway, switching between the overtaking lane and the regular lane. Do not make sudden decelerations or stops without warning. While driving, avoid driving side by side with other vehicles, staying in the overtaking lane for extended periods, or attempting to overtake from the emergency lane. Additionally, prepare for lane changes in advance when exiting the highway to avoid missing the exit.

How many kilometers can a set of brake pads last?

The mileage depends on the car's usage. Generally, they need to be replaced every 50,000 kilometers, while some drivers can go up to 100,000 kilometers before replacement. In fact, under normal driving conditions, the service life of front brake pads is 30,000 kilometers, while rear brake pads last about 60,000 kilometers. Rust on car brake discs is a normal phenomenon. Here are detailed explanations about it: 1. Minor rust: Minor rust often occurs, such as after the car is left in the rain overnight or when it doesn't dry properly after washing. In such cases, continuous braking while driving can help remove the rust, as the friction between the brake disc and the brake caliper during braking will wear off the rust over multiple applications. 2. Severe rust: If the brake disc has severe rust, the entire surface may be covered with a thick layer of rust. Stubborn rust can also accelerate the wear of brake pads, so it's necessary to take the car to a repair shop to have the brake discs polished.

What are the folk methods to determine if a three-way catalytic converter is clogged?

The following are folk methods to determine if a three-way catalytic converter is clogged: 1. Check whether the voltage of the front and rear oxygen sensors of the three-way catalytic converter is consistent: if they are consistent, it means the three-way catalytic converter is damaged, that is, it is clogged or burned out due to engine misfire. 2. Feel the airflow: put your hand near the exhaust pipe to see if you can feel the airflow. If you can't feel it, it means it's clogged. 3. Temperature difference: judge whether it is clogged by sensing the temperature difference before and after the three-way catalytic converter. Causes of three-way catalytic converter clogging: 1. Gasoline: high sulfur content in gasoline can easily form chemical complexes in the three-way catalytic converter, causing clogging. 2. Engine oil: long-term use of engine oil containing sulfur and phosphorus antioxidants can easily cause clogging of the three-way catalytic converter. 3. Road conditions: since the most incomplete combustion products are generated during acceleration and deceleration, long-term driving on congested roads can easily cause clogging of the three-way catalytic converter.

How to Remove the Gear Knob of a Suzuki Swift?

Suzuki Swift gear knob removal method introduction: After removing the clip on top, it can be directly unscrewed. Gear shifting (changing gears) refers to the transmission, which is used to change the torque and speed of the engine crankshaft to meet the different needs of the driving wheels for traction and speed under various driving conditions such as starting, accelerating, driving, and overcoming various road obstacles. Below is an introduction to the differences between manual and automatic transmissions: 1. Different gear shifting. Manual transmission cars require constant gear shifting based on speed while driving, while automatic transmissions are more comfortable, with gears shifting automatically, which is also the biggest difference between manual and automatic transmissions. 2. Different starting methods. When starting, manual transmission cars require pressing the clutch and brake, then shifting into first gear and slowly releasing the clutch and brake to start. Automatic transmissions are simpler, requiring only shifting into D gear and pressing the accelerator to start. Manual transmissions may stall. 3. Different parking methods. Manual transmission cars require pressing both the clutch and brake simultaneously when parking, then slowing down to stop, and shifting into neutral after stopping. Automatic transmissions require no additional operations, just pressing the brake to stop, then shifting into P gear.

Can 15w40 engine oil be used in sedans?

15W40 and 20W50 are two different grades of engine oil, but both belong to multi-grade oils. The "W" stands for Winter, the number before "W" represents low-temperature fluidity, and the number after "W" represents high-temperature viscosity. Thus, the difference between 15W40 and 20W50 lies in their low-temperature fluidity and high-temperature viscosity. For sedans, 15W40 engine oil can be used, but it is more suitable for summer conditions. Relevant information about engine oil is as follows: 1. Introduction: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10³ (kg/m³). It serves functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. It is often referred to as the "blood" of a car. 2. Composition: Engine oil consists of base oil and additives. The base oil is the main component, determining the basic properties of the lubricant, while additives compensate for and improve the shortcomings of the base oil, providing certain new properties. Additives are an important part of engine oil.
