Where is it not allowed to overtake when driving on the road?

Places where overtaking is not allowed when driving on the road include curves, etc. Below is an introduction to places where overtaking is not allowed: 1. Special road sections where overtaking is not allowed: Overtaking is not allowed on curves. Overtaking is not allowed on slopes because accelerating to overtake is dangerous. Overtaking is not allowed when crossing bridges. Overtaking is not allowed when there are intersections or crossings ahead. Overtaking is not allowed when there is an oncoming vehicle within 200 meters. When driving on highways, overtaking is not allowed after entering deceleration lanes, acceleration lanes, or ramps. Overtaking is not allowed when entering or exiting toll stations and service areas. 2. Unsafe times when overtaking is not allowed: Overtaking is not allowed when the vehicle ahead signals a left turn or U-turn. Overtaking is not allowed if there is a possibility of meeting an oncoming vehicle during the overtaking process. Overtaking is not allowed when the vehicle ahead is overtaking another vehicle. Overtaking is not allowed when the vehicle ahead is a police car, fire truck, etc., performing emergency tasks. Overtaking is not allowed when weather conditions are poor.

What car has an 'L' logo?

There are currently three car brands with an 'L'-shaped logo in the market: 1. Import brand: Lexus: Lexus, formerly known as 'Lingzhi' in Chinese, was established in 1983. It is a luxury car brand under the Toyota Group. Within just over a decade of its founding, Lexus achieved sales in North America comparable to the three major German luxury brands (BBA) and ranked first in the U.S. luxury car sales chart for 11 consecutive years. 2. Joint venture brand: Luxgen: Luxgen originates from Taiwan's largest automobile manufacturer, Yulon Group, which later established a joint venture subsidiary in mainland China. The brand primarily produces MPVs, SUVs, and compact cars. Positioned as 'an indigenous brand with innovative technology, starting late but leading the world,' Luxgen is a car brand that evokes strong reactions. 3. Domestic brand: Lifan: Lifan Group, founded in 1992, is one of China's largest private enterprises. It operates three major automobile production bases: Lifan Passenger Vehicle Company mainly produces cars and commercial vehicles, Lifan Yunnan Dali Junma Company focuses on trucks and lorries, and Lifan Beiquan Automobile Factory specializes in buses.

What Maintenance is Needed for a Car at 30,000 Kilometers?

Generally, the maintenance items for a car at 30,000 kilometers include changing the engine oil, oil filter, air filter, fuel filter, throttle cleaning, and replacing spark plugs. Some 4S shops may recommend additional maintenance items, which can be considered based on personal preference and actual conditions. Below are some extended details: 1. Engine Oil and Four Filters: The four filters in the engine oil system include the oil filter, air filter, fuel filter, and cabin air filter. The oil filter should be replaced at every maintenance interval, while the air filter is recommended to be replaced every 10,000–15,000 kilometers, the fuel filter every 30,000 kilometers, and the cabin air filter every six months. To save costs, you can skip replacing the cabin air filter. However, the fuel filter must be replaced during the major 30,000-kilometer maintenance. 2. Throttle Cleaning: Throttle cleaning is unnecessary before 30,000 kilometers. If a 4S shop or repair shop recommends this service at 10,000 or 20,000 kilometers, you can directly refuse. Over time, carbon deposits accumulate at the throttle valve due to prolonged air intake, leading to reduced airflow. This can cause minor idle instability, idle shaking, weak acceleration, and indirectly increase fuel consumption. 3. Spark Plugs: Spark plugs should be replaced at 30,000 kilometers. Although they may not have completely lost their ignition performance by this point, their efficiency is significantly reduced. Poor ignition performance directly affects idle shaking, engine misfires, and weak acceleration. It also increases engine load, contributing to higher fuel consumption. 4. Air Conditioning Cleaning: Air conditioning cleaning removes dust, dirt, and bacteria from the air conditioning system. This service is optional. If the car has never undergone air conditioning cleaning before 30,000 kilometers, it is advisable to do it now.

How Much Engine Oil in the Car is Considered Normal?

Generally, the engine oil level in a car is considered normal when it is between the upper limit (MAX) and the lower limit (MIN). The optimal oil level is slightly closer to the upper limit. If the oil level is below the lower limit (MIN), it is not normal and requires maintenance. Additionally, when checking the oil level, the dipstick should be fully inserted. Below is more related information: 1. Functions of Engine Oil: "Engine oil" is an essential lubricant for ensuring the normal operation of the engine. Its specific functions include lubricating metal components, reducing friction between parts, dissipating the immense heat generated during engine operation, cleaning fine metal particles produced by wear, as well as providing sealing, vibration damping, and rust prevention. However, when adding engine oil, it is important to ensure the amount is neither too much nor too little. The oil level should be between the "low" (MIN) and "full" (MAX) marks on the dipstick. An oil level that is too low can lead to insufficient oil pressure, while an excessive oil level can increase the working resistance of the crankshaft and connecting rods and accelerate the formation of carbon deposits in the combustion chamber. 2. Precautions: After changing the engine oil in a car, the oil level should generally be between the lower line (MIN) and the upper line (MAX) on the dipstick. It is advisable not to exceed the upper line. Overfilling can cause issues such as foaming due to the crankshaft's agitation, which may damage the engine. Staying below the upper line is safe. After starting the engine, the oil level should ideally be in the middle to upper range. Overfilling may lead to problems like sluggish engine performance and oil seal leakage.

Why Does the Fan Keep Running After the Car Is Turned Off?

Fan keeps running because the engine coolant temperature is too high. Here is some extended information about high engine coolant temperature: 1. Causes: There are several reasons that can cause the engine coolant temperature to rise excessively or even boil over, such as damaged electronic components in the cooling system (thermostat, cooling fan), poor radiator performance, or insufficient coolant. 2. Solutions: Check if the lack of antifreeze is causing the high engine temperature. Also, inspect the coolant circulation to see if it is obstructed. Additionally, components like the coolant temperature sensor, water pump, thermostat, and cooling fan could all contribute to high temperatures. It is recommended to visit a repair shop for maintenance.

How to adjust the valve clearance of the SFH C9 engine?

No need to remove the magneto cover. Insert a 17mm socket into the valve position, shine a light inside, and you will see a marking line. Adjust the valve clearance by aligning with this line. Remove the valve cover, then remove the cylinder head. You will see two screws. First, shake them slightly to feel the clearance, then adjust it to be slightly smaller.
