Here is the introduction to the speed limits for 30, 40, 50, and 70 in Subject One: Urban roads without centerlines: The maximum speed limit for urban roads without road centerlines is 30 km/h. Urban roads with centerlines: The maximum speed limit for urban roads with road centerlines is 50 km/h. Highways with centerlines: The maximum speed limit for highways with road centerlines is 70 km/h. Highways without centerlines: The maximum speed limit for highways without road centerlines is 40 km/h. Below is extended information on speed limits for two-lane and three-lane highways: Two-lane highways: The so-called two-lane highway speed refers to highways with two lanes in the same direction. The speed range for the right lane is 60 km/h to 100 km/h, and the speed range for the left lane is 100 km/h to 120 km/h. Three-lane highways: The three-lane highway speed refers to highways with three lanes in the same direction. The speed range for the far-right lane is 60 km/h to 90 km/h, the middle lane is 90 km/h to 110 km/h, and the far-left lane is 110 km/h to 120 km/h. The left lane is the overtaking lane, hence the higher speed limit.

When teaching students to drive, I often emphasize the '30-40-50-70 speed mnemonic' for subject one, which refers to speed limits on different types of roads. 30 represents urban roads without a center line, with a maximum speed of 30 kilometers per hour, suitable for residential areas or small lanes; 40 is for roads without a center line, such as rural roads, with a speed limit of 40; 50 is for urban roads with a center line, where the speed can reach 50 kilometers per hour; and 70 is for roads with a center line, such as national highways or suburban roads, with a speed limit of 70. These numbers serve as a shorthand in exams, helping learners quickly memorize key regulatory points. Mastering it is not just for passing the test but also enhances daily driving safety and reduces accidents. Especially at night or in adverse weather conditions, these lower speed settings provide protection. Beginners often overlook these small details and tend to make mistakes in mock tests. After memorizing the mnemonic, practical application becomes much smoother.

What are the symptoms of a fuel pump detection failure?

The symptoms of a fuel pump detection failure include: weak engine acceleration; difficulty starting the car, requiring multiple ignition attempts; uneven or shaky engine rotation; unusual noises from the engine while driving; a jerking sensation when accelerating sharply; and abnormal engine shaking. Causes and solutions for fuel pump failures: Fuel quality is the most direct cause of fuel pump damage. Solution: Strictly follow the manufacturer's recommended fuel grade and ensure the car never runs out of fuel. Improper refueling practices can damage the fuel pump. Solution: Always refuel according to the specified guidelines. Driving with low fuel levels for extended periods prevents the fuel pump from cooling. Poor fuel quality with excessive impurities can lead to frequent clogging and irregular operation of the fuel pump. Solution: Avoid waiting until the fuel warning light comes on before refueling, as this shortens the fuel pump's lifespan. Running on very low or empty fuel can burn out the pump. Always filling the tank to the brim when refueling. If you frequently drive in the city and have easy access to fuel, there's no need to fill up completely, as this may cause the fuel float and sensor to malfunction, distort the fuel gauge, and increase fuel consumption. Solution: It is recommended to refuel when the fuel level is low but not yet critical.

What is the difference between China V and China VI engines?

The biggest difference between China V and China VI engines lies in the fact that China VI vehicles use a more efficient three-way catalytic converter. Below are detailed introductions about China V and China VI: 1. China V and China VI refer to the national automobile emission standards: Emission standards regulate the content of harmful gases such as carbon monoxide, hydrocarbons (HC), nitrogen oxides (NOx), particulate matter, and soot in vehicle exhaust. 2. China V and China VI have different environmental protection levels: China VI sets higher emission standards for automobile engines and a higher environmental protection level. The China VI standard stipulates that the sulfur content in emissions should not exceed 50mg/kg, while the China V standard stipulates that the sulfur content should not exceed 10mg/kg.

How many cylinders does the Honda XR-V engine have?

The L15B5 is the engine model used in the Honda XR-V, with a maximum horsepower of 131 hp, a maximum power output of 96 KW, a maximum power speed of 6600 rpm, and a peak torque of 155 N.m. The Honda XR-V engine is produced at Dongfeng Honda's Wuhan factory, while the Vezel 1.8 engine is manufactured at the Dongfeng Honda factory. After 2016, the 1.5 engine is produced at Guangqi Honda's Zengcheng third factory. Regular maintenance can be performed using the following methods: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the oil and oil filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine problems. To avoid faults, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication area, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates properly but also extends the overall lifespan of the radiator and engine.

What Costs Are Included in Vehicle Expenses?

In addition to the vehicle price, the costs that need to be paid when purchasing a car include: vehicle purchase tax, vehicle and vessel usage tax (varies by region), compulsory traffic insurance, commercial insurance (optional based on personal needs), and license plate registration fee (varies by region). Below is a detailed introduction: 1. Vehicle Purchase Tax: This is a tax levied on units and individuals purchasing specified vehicles within the country, determined by the vehicle's ex-factory price and engine displacement. The latest policy sets the vehicle purchase tax at 10%. 2. Insurance Costs: This includes compulsory traffic insurance and commercial insurance. Compulsory traffic insurance is mandatory, with a nationally unified fee standard, though the number of car seats can affect the amount. Commercial insurance can be purchased voluntarily, with prices varying. 3. License Plate Registration Fee: After completing insurance and tax payments, you need to take these documents to the vehicle management office for registration, i.e., obtaining a license plate. Only after receiving the vehicle registration certificate and license plate does the car fully belong to you. If you handle the registration yourself, the process can be complex and tedious; if you don't have time, you can opt for a 4S store to handle it, though the fee will be relatively higher. 4. Vehicle and Vessel Tax: This is a behavioral tax levied on vehicles driving on public roads and vessels sailing in domestic rivers, lakes, or territorial ports, calculated based on their type, tonnage, and stipulated tax rates. As a local tax, the vehicle and vessel tax varies by region, with fees categorized by engine displacement.
