Can Private Cars Carry Passengers for Hire?

No. Private cars carrying passengers for hire will be ordered to cease operations by the road transport management agencies at or above the county level; if there are illegal gains, such gains will be confiscated and a fine ranging from 2 to 10 times the illegal gains will be imposed. The following is an introduction to illegal operations: Road Passenger Transport Operations: Refers to the activity of transporting passengers or goods on roads using transportation vehicles. Road transport activities can be divided into commercial road transport and non-commercial road transport based on whether they are profit-oriented. Commercial Road Transport: Commercial road transport, also known as road transport operations, mainly refers to road transport that provides services to the public, involves fee settlements, or obtains remuneration. During commercial road transport, various settlement methods are used, including not only separate settlement of freight charges but also combined settlement of freight charges and loading/unloading fees with the price of goods, freight charges and loading/unloading fees with project costs, and freight charges with service fees or contract fees, among others.

What is the Speed Ratio of Pulleys?

The calculation formula for pulley speed: Assuming the diameter and speed of the motor pulley (driving pulley) are d1 and n1, and the diameter and speed of the driven pulley are d2 and n2, the mechanical transmission principle yields the pulley speed calculation formula: d2/d1 = n1/n2 = i; that is, d2 = d1 × (n1/n2). Below are related introductions: Definition: Pulleys belong to the category of hub-like components, generally relatively large in size, and are primarily manufactured through casting or forging in terms of production processes. Larger-sized designs typically employ casting methods, with materials usually being cast iron (which has good casting properties), and rarely cast steel (as steel has poor casting properties). Representation: It is denoted by the symbol "n"; its international standard unit is r/s (revolutions per second) or r/min (revolutions per minute), and it is also represented as RPM (revolutions per minute, mainly used in Japan and Europe). When the unit is r/s, the value is equal to the frequency, i.e., n = f = 1/T, where T is the period of circular motion.

What Causes the Squeaking Sound When Pressing and Releasing the Clutch Pedal?

It is caused by poor lubrication, wear, looseness, or damage of the clutch release bearing. Lubricating oil needs to be added to the clutch release bearing or it should be replaced promptly. Abnormal Clutch Issues in Vehicles: Pay Attention to Clutch Slippage: If the free travel of the clutch pedal is too small, the release bearing frequently presses against the diaphragm spring, keeping the pressure plate in a semi-engaged state. Alternatively, the clutch pressure plate spring may be too soft or broken, or the screws connecting the clutch to the flywheel may be loose. Incomplete Disengagement: With the engine idling, the clutch only disengages when the clutch pedal is pressed almost to the floor. If pressing the clutch pedal makes it difficult to shift gears or causes a harsh grinding noise from the transmission, or if the vehicle starts moving without lifting the clutch pedal after shifting, these indicate incomplete clutch disengagement. Measuring the Pedal Travel: The clutch should firmly engage when the pedal is pressed to 3/4 of its travel. Otherwise, check if the travel is appropriate. Use a ruler to measure the pedal height at its highest position, then measure the height when resistance is felt upon pressing the pedal. The difference between these two values is the clutch pedal travel.

Volkswagen CC 30,000 km Maintenance Items

For the Volkswagen CC's 30,000 km maintenance, replacing the engine oil and oil filter is a mandatory task. Under the high-temperature and high-pressure conditions inside the engine, the shelf life of engine oil is significantly shortened, and its performance greatly deteriorates. Over time, it fails to protect the engine effectively. The oil filter prevents impurities from mixing into the oil, which can cause oxidation, leading to the formation of sludge and clogging the oil passages. Both the engine oil and oil filter should be replaced simultaneously. The air filter should be replaced every 10,000–15,000 km, and the fuel filter every 30,000 km. 1. Engine oil and four filters. The four filters include: oil filter, air filter, fuel filter, and cabin air filter. The oil filter needs to be replaced at every maintenance service, while the air filter is recommended for replacement every 10,000–15,000 km, and the fuel filter every 30,000 km. The cabin air filter is suggested to be replaced every six months. If cost-saving is a priority, the cabin air filter can be skipped. However, the fuel filter must be replaced during the 30,000 km major maintenance. 2. Throttle body cleaning. Throttle body cleaning is unnecessary before 30,000 km. If a 4S shop or repair shop staff recommends this service at 10,000 or 20,000 km, you can directly decline. By 30,000 km, the car has typically been driven for at least a year or more. Over time, the throttle body accumulates carbon deposits at the intake due to prolonged use, leading to reduced airflow. This can cause minor idle instability, idle vibration, sluggish acceleration, and indirectly increase fuel consumption. At this point, it's advisable to inspect the throttle body, spark plugs, and other components that might contribute to these issues. 3. Spark plugs. By 30,000 km, the spark plugs are due for replacement. Although they haven't completely lost their ignition capability, their performance has significantly degraded. Poor ignition directly affects idle vibration, engine misfires, and weak acceleration. Reduced ignition performance also increases engine load, which is one of the factors contributing to higher fuel consumption. 4. Air conditioning system cleaning. Air conditioning cleaning removes dust and dirt from the AC ducts and provides a sterilizing effect. This service is optional. However, if the car has never undergone AC cleaning before 30,000 km, now is a good time to do it.

What does the battery exclamation mark mean in new energy vehicles?

There are five possible scenarios when an exclamation mark appears on the car dashboard: general malfunction, automatic transmission failure, brake system failure, abnormal tire pressure, and lighting malfunction. Below is a detailed analysis of these five situations: General malfunction: A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. It is necessary to visit a 4S shop for inspection to identify the source of the problem. Automatic transmission failure: A yellow gear with an exclamation mark inside is the automatic transmission failure warning light, indicating a transmission malfunction or transmission fluid level below the normal range. Transmission fluid should be replaced promptly. Brake system failure: An exclamation mark inside a circle with parentheses represents a brake system warning, typically indicating brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Abnormal tire pressure: An exclamation mark with a horizontal line below parentheses is the tire pressure monitoring warning light, which illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting malfunction: A yellow bulb with an exclamation mark is the lighting malfunction indicator, signaling a fault in the vehicle's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.

Where to Find the Chassis Number and Engine Number?

The engine number is generally located on the outer surface of the engine block, or on the vehicle's nameplate or the nameplate inside the engine compartment. The simplest and most direct method is to check the vehicle's administrative green book or the vehicle registration certificate. The engine number, like a person's ID number, represents each vehicle and contains very important information about the car. The chassis number is stamped on the vehicle's frame. The specific location varies by manufacturer, so you can refer to your vehicle's manual. The engine model number is an identification code assigned by the engine manufacturer in accordance with relevant regulations, industry practices, and the engine's attributes. It represents information such as the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and static brake power. Engines installed in passenger cars or multi-purpose vehicles are marked with the professional manufacturer's name, model, and production number as required. The chassis number, commonly referred to as the Vehicle Identification Number (VIN), is a unique code assigned by the manufacturer to identify a vehicle. The VIN consists of 17 alphanumeric characters, also known as the 17-digit identification code, chassis number, or 17-digit number. The combination of these characters ensures that no two vehicles of the same model will have the same number within 30 years, making it a unique identifier for the vehicle—often called the 'car's ID card.' It is typically found in the following locations: on the vehicle registration certificate and on the lower left side of the front windshield. It's important to note that the engine number is not the same as the engine model number. The engine model refers to the specifications and size of the engine within the manufacturer's lineup, and multiple engines can share the same model number. The engine number, however, is the production serial number of the engine, and each engine has a unique number. Engine Number Composition: First Part: Includes the product series code, generation symbol, and regional or manufacturer code. Manufacturers may choose appropriate letters, but these must be approved and recorded by the industry standard authority. Middle Part: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Rear Part: Composed of symbols for structural features and usage characteristics. Tail Part: A distinguishing symbol. Manufacturers may use appropriate symbols to differentiate between improved versions or other variations within the same series. The rear and tail parts may be separated by a hyphen. The chassis number consists of 17 characters divided into three parts. Part 1: WMI—World Manufacturer Identifier (positions 1–3); Part 2: VDS—Vehicle Descriptor Section (positions 4–9); Part 3: VIS—Vehicle Identifier Section (positions 10–17).
