How to Conduct Annual Inspection for China VI Vehicles?

For China VI vehicles, the annual inspection must be conducted within three months before the expiration of the motor vehicle inspection validity period. You need to directly bring the vehicle license, vehicle and vessel tax or tax exemption certificate, and compulsory traffic insurance to the designated processing points to apply for the inspection compliance mark. Inspection stations will no longer handle inspection services for vehicles eligible for exemption. Vehicle annual inspection refers to the annual examination conducted in accordance with relevant regulations for vehicles that have already obtained formal license plates and vehicle licenses. The purpose of the annual inspection is to check the main technical conditions of the vehicle, urge the strengthening of vehicle maintenance, keep the vehicle in good condition, and ensure driving safety. Vehicles with any of the following conditions must be processed according to relevant regulations before inspection: 1. Vehicle conditions do not match those recorded in the vehicle license or archives; 2. License plates or vehicle licenses are damaged, incomplete, illegible, or self-replicated; 3. Vehicle modifications, model changes, or technical transformations have not undergone approval and change procedures; 4. Failure to spray the unit name and enlarged license plate characters as required; 5. Failure to install alarms or indicator lights as required; 6. Failure to pay road maintenance fees and insurance as required.

What Type of Fire Extinguisher Should Be Used for a Car Fire?

For car fires, use a dry powder fire extinguisher or a water-based fire extinguisher. The main component of a water-based fire extinguisher is RO purified water, which features no dust, suffocation prevention, effective fire suppression, and non-toxic environmental protection. It can spray fire suppressant to evaporate heat from the fire scene, rapidly lower the temperature, and inhibit thermal radiation. Surfactants quickly form a water film on the surface of combustibles, isolating oxygen and providing both cooling and isolation effects, while also participating in fire suppression. This achieves the goal of rapid fire extinguishing without re-ignition. Precautions for using water-based fire extinguishers: 1. Water-based foam fire extinguishers are not suitable for electrical fires. When dealing with electrical fires, the power must first be cut off, and live operation is strictly prohibited to avoid electric shock. 2. When performing maintenance and refilling of the fire extinguisher, it must be done according to its requirements and recommendations.

Which Cars Use Rotary Engines?

Mazda's models utilize rotary engines, such as the Mazda RX7 and Mazda RX8. The rotary engine eliminates the reciprocating motion effect of pistons in traditional engine cylinders, directly converting the combustion expansion force of fuel and mixed gases into driving torque. Therefore, in terms of size, the rotary engine is smaller than traditional engines, while also featuring a low center of gravity and lightweight characteristics, which to some extent can enhance the car's handling. The Mazda RX8 is a sports car under Mazda, with dimensions of 4460mm in length, 1770mm in width, and 1340mm in height, and a wheelbase of 2700mm. The Mazda RX8's engine has a maximum power of 170 kilowatts and a maximum torque of 211 Newton-meters. This engine is equipped with direct fuel injection technology and uses an aluminum alloy cylinder head and block.

Is the highway toll-free during the Mid-Autumn Festival?

Highways charge tolls during the Mid-Autumn Festival. According to regulations: the toll-free periods are limited to four national statutory holidays—Spring Festival, Tomb-Sweeping Day, Labor Day, and National Day—as well as the consecutive holidays determined by the State Council in the same year. The toll-free period starts at 00:00 on the first day of the holiday and ends at 24:00 on the last day. Vehicles eligible for toll-free passage on highways are passenger vehicles with seven seats or fewer (including seven seats), as well as motorcycles permitted on ordinary toll roads. During the toll-free period, it is recommended to use ETC lanes for both entering and exiting the highway. If you enter via an ETC lane, you can exit through either an ETC or manual lane without affecting ETC usage. However, if you enter via a manual lane, you must also exit through a manual lane; exiting via an ETC lane will not be possible.

How many kilometers should the Nissan Sylphy's spark plugs be replaced?

Nissan Sylphy's spark plugs should be replaced every 60,000 kilometers. Spark plugs are a crucial component of the gasoline engine's ignition system. They introduce high-voltage electricity into the combustion chamber, causing it to jump across the electrode gap and generate a spark, thereby igniting the combustible air-fuel mixture in the cylinder. To some extent, the performance of the spark plugs directly affects the ignition and combustion of the mixture. The Sylphy is a compact sedan under Nissan, with dimensions of 4,641 mm in length, 1,815 mm in width, and 1,450 mm in height, and a wheelbase of 2,712 mm. In terms of power, the Sylphy is equipped with a 1.6-liter naturally aspirated engine across all models. This engine delivers a maximum power of 99 kW and a maximum torque of 159 Nm. It features EVTC technology and multi-point fuel injection, and utilizes an aluminum alloy cylinder head and block.
