Auxiliary road vehicles refer to the lanes on both sides of the main road, which are designed to assist the main road in traffic flow. The main road is exclusively for motor vehicles, while the auxiliary road accommodates mixed traffic of motor vehicles, non-motor vehicles, and pedestrians. Main road vehicles travel on the regular traffic lanes. The speed limits differ: auxiliary road vehicles are not allowed to exceed 60 km/h, whereas main road vehicles can reach speeds of 80 km/h or more. Classification based on usage, function, and traffic volume: 1. Expressway: A multi-lane highway exclusively for motor vehicles with controlled access and divided lanes for directional traffic. 2. Class I Highway: A multi-lane highway for motor vehicles with divided lanes and optional access control. It connects expressways or serves as a main road in urban-rural fringe areas, economic zones of development areas, and sparsely populated regions. 3. Class II Highway: A two-lane highway for motor vehicles, typically serving as a main road in medium-sized or larger cities or connecting to large industrial zones and ports. 4. Class III Highway: A two-lane highway primarily for motor vehicles, functioning as a distributor road connecting counties and towns. 5. Class IV Highway: A two-lane or single-lane highway mainly for motor vehicles, serving as a local road connecting villages and rural areas.

How many kilometers can a BMW run-flat tire travel after a puncture?

BMW run-flat tires can travel 80 kilometers after a puncture. Impact of a puncture: With run-flat tires, the vehicle can still travel 80 kilometers at a speed of 80 km per hour even when the tire is deflated. However, if the driver lacks experience in driving after a puncture, they might make incorrect driving maneuvers, such as sudden braking. This could lead to uncontrollable loss of vehicle control, as a puncture is a very serious safety incident, especially on highways. Purpose of equipping run-flat tires: Fitting a vehicle with run-flat tires largely addresses the concerning safety issues. Distance a run-flat tire can travel after a puncture: Generally, a run-flat tire can support the vehicle for about 250 kilometers after a puncture. However, in cases of significant damage (e.g., a large puncture from a sharp object) or poor road conditions, the travel distance may be reduced to just a few dozen kilometers.

How often should the coolant be replaced in a Magotan?

The coolant in a Magotan should be replaced every two years or 40,000 kilometers. This is just a reference interval. For commercial vehicles with higher mileage, the replacement interval should be shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Check the coolant level regularly and top it up if it is insufficient. If you notice any suspended particles, sediment, or discoloration in the coolant, replace it immediately and clean the system. Coolant replacement method: Before completely replacing the coolant, conduct a thorough inspection to check for any leaks or cracks in the pipes, especially the five-way hose. The five-way hose is named for its five connection points to different parts of the vehicle. Coolant flows through this hose and is distributed to various parts of the car. If there is any coolant leakage in this area, replace the hose or reseal the connections as needed. Drain the old coolant and flush the channels with clean water. Add water to the coolant reservoir and let it circulate continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to allow the water to circulate. Initially, the water draining out will have a faint pink color. Continue adding clean water until the water runs clear. Remember to remove the heater hose and drain the water from the heater core. After draining for about an hour, add the new coolant through the radiator hose to allow it to flow quickly into the radiator. Then, fill the coolant reservoir with another bottle of coolant until it is nearly full. Start the engine and let it run for about 10 minutes. As some air is expelled from the cooling system, the coolant level will drop. Top it up again until it reaches the "MAXT" mark on the reservoir.

How to Remove Engine Sludge?

You can use a dedicated sludge cleaning oil. After draining all the engine oil, add the cleaning oil to the engine, let the engine idle for 15 minutes, and then drain the cleaning oil. Here is some extended information about the engine: 1. After prolonged use, a car's engine may develop sludge or internal carbon deposits. However, sludge is harmful to the engine as it can clog the oil passages, affecting the engine's lubrication. 2. The engine contains oil, which needs to be pumped by the oil pump to various parts of the engine that require lubrication. If the oil passages are clogged, the oil cannot reach these parts, which will accelerate engine wear.
