What does the inspection validity period mean?

The inspection validity period refers to the validity period of the driver's license inspection. Below are the required documents for driver's license inspection: 1. Identification: Resident ID card (for those holding ID cards from other provinces or cities, a temporary residence permit is also required) and a copy. 2. Original driver's license: The original motor vehicle driver's license and the currently held driver's license. 3. Photos: Three recent 1-inch white-background color photos. 4. Medical report: A qualified medical examination report from a district or county-level hospital or above. Such hospitals usually have medical examination points near the vehicle management office or traffic police station. 5. Application form: The applicant should obtain the 'Motor Vehicle Driver's License Application Form' at the vehicle management office and fill it out according to the instructions.

What Are the Hazards of Flood-Damaged Cars?

Flood-damaged cars have the following hazards: 1. Hazard one: The biggest hazard lies in the electrical circuits, which may malfunction at any time, even leading to the car breaking down and failing to start. These faults are troublesome to diagnose and repair, and the maintenance costs are relatively high. 2. Hazard two: After being soaked in water, interior components such as seat foam, carpets, and soundproofing materials can breed mold and bacteria, leading to unpleasant odors and even viruses that pose health risks to passengers. 3. Hazard three: The metal surfaces of the car body will accumulate mud and sand due to water immersion, and the absorbed moisture will cause rust over time, affecting the strength and rigidity of the car body and creating safety hazards.

What is the position of the car gear lever called?

The position of the car gear lever is called the gear shift console. Here is a detailed introduction about it: 1. Introduction 1: The gear lever, also known as the operation lever, is used on the car transmission and its main function is to support the car's gear shifting. 2. Introduction 2: The gear lever is a rod-like component, commonly divided into 1-2 gear levers, 3-4 gear levers, and five-gear levers. 3. Introduction 3: From a technical perspective, electronic gear levers have a high degree of freedom, with flexible and varied positions and forms. Currently, representative types include BMW's electronic wiring type, Mercedes-Benz's column-mounted type, Land Rover's rotary knob type, and Lincoln's button type.

What is the function of a car tachometer?

The functions of a car tachometer are as follows: 1. Display engine speed: It reflects whether the engine is operating at normal speed and serves as a barometer for the engine's working condition. When the engine is idling or in neutral, the speed should be stable and within a reasonable range. When pressing the accelerator pedal in neutral, the speed should change smoothly with the steady rise and fall of the pedal. When holding the accelerator pedal steady, the tachometer needle should remain fixed at a certain speed mark. 2. Serve as a reference for manual transmission gear shifting: Selecting the appropriate gear shifting timing allows the engine to always operate within the most economical working range. The engine's torque reaches its maximum only within a certain range. Beyond this range, the torque will drop significantly, resulting in insufficient engine power, sluggish car acceleration, or even gear dragging and stalling.

Where is the car air conditioning sight glass hole located?

Car air conditioning sight glass hole is located in the engine compartment. Here are detailed explanations about it: 1. Explanation one: It's normal to see bubbles in the refrigerant sight glass. Every vehicle's air conditioning system will show a small amount of bubbles in the sight window because there's inevitably some gas mixed in when refrigerant is collected into bottles during production. 2. Explanation two: The standard refrigerant charge should be determined either according to the standard refrigerant filling quantity marked on the product nameplate of the air conditioning system, or by roughly estimating the appropriate refrigerant charge based on the operating state parameters of the air conditioning refrigeration system pipelines. 3. Explanation three: Generally, the high pressure of car air conditioning systems is around 150, and the low pressure is around 30 (these two values are marked on refrigerant gauges). This represents the optimal pressure state for most air conditioning systems.

What are the engine specifications of the Touran?

The Touran's engine has a maximum power of 110kW, maximum horsepower of 150, and maximum torque of 250Nm, with the model designation EA111. The Touran engine is a Sino-German joint venture, produced by Shanghai Volkswagen, and is classified as a domestically manufactured engine. For daily maintenance of the Touran engine, the following methods can be used: 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 specified requirements; Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, causing various problems for the engine. To avoid malfunctions, change the oil regularly according to 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 areas, 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 radiator cleaner to clean the radiator. Removing rust and scale deposits not only ensures proper engine operation but also extends the overall lifespan of the radiator and engine.
