Are the toll fees the same for 7-seater and 5-seater vehicles?

7-seater and 5-seater vehicles have the same toll fees, with no difference in charges. According to the 'Toll Road Vehicle Classification Standards,' both are uniformly classified as Class 1 small passenger vehicles. Therefore, the highway toll standards for these two types of vehicles are the same. More details are as follows: 1. During annual inspections: The annual inspection is likely where 5-seater and 7-seater vehicles differ the most. According to regulations, small passenger vehicles with 7 seats or more continue to follow the original policy of inspection every 2 years, while those with 6 seats or fewer can be inspected every 6 years. 2. Compulsory traffic insurance is mandatory for vehicle owners every year. For 5-seater vehicles, the annual fee is 950 yuan, while for 7-seaters, it is 1100 yuan. Additionally, the seat insurance for the two extra seats in a 7-seater naturally costs more than that for a 5-seater.

What Causes High Exhaust Temperature Alarm in China VI Diesel Vehicles?

China VI diesel vehicles high exhaust temperature alarm causes: The idle switch does not close, the idle contact is disconnected, the ECU determines that the engine is under partial load. At this time, the ECU determines the fuel injection quantity and injection time based on the air flow sensor, crankshaft position, and speed signals. The exhaust temperature increases because modern vehicles are equipped with three-way catalytic converters. Types of exhaust systems: Exhaust temperature protection is one type of compressor temperature protection device. Effects of excessive temperature: During compressor operation, certain factors can cause the exhaust temperature to exceed normal values. This not only increases compressor power consumption but also causes lubricating oil to carbonize, degrading its performance and affecting the compressor's normal operation. To avoid excessively high exhaust temperatures, an injection valve can be used to control the exhaust temperature.

Is Vehicle Title Transfer Necessary When Selling a Car?

Selling a car requires a title transfer. Otherwise, the seller may be held liable in case of an accident. Title Transfer Requirements: To complete the vehicle title transfer process, all prior traffic violations must be resolved, the vehicle must pass inspection, and the physical presence of the vehicle is required. Both the buyer and seller must present their respective identification documents and vehicle paperwork (including the vehicle registration certificate and vehicle license) and jointly visit the local DMV where the vehicle is registered to complete the title transfer procedure. Relevant Laws: "Motor Vehicle Registration Regulations": Article 13 states that when a vehicle owner's residence changes beyond the jurisdiction of the current DMV, the DMV shall, within three days of acceptance, annotate the changes on the vehicle registration certificate, reclaim the license plates and vehicle license, issue a temporary license plate valid for 30 days, and hand over the vehicle's file to the owner. The vehicle owner must apply for vehicle registration transfer at the new residence's DMV within the validity period of the temporary license plate.

What Causes High Engine Temperature Alarm?

Reasons for high engine temperature alarm: Insufficient coolant: Possible causes include insufficient engine coolant, faulty water temperature sensor or gauge, and prolonged low-speed, high-load driving during hot seasons, which can also lead to high temperatures. Overheating: When encountering a high water temperature alarm, first reduce speed and pull over to the roadside. Do not rush to turn off the engine, as excessive heat can cause components like pistons, cylinder walls, and the crankshaft to overheat, thinning the oil and reducing lubrication. Engine seizure: If the engine is turned off at this point, the parts are still in an expanded state with minimal clearance between them. Shutting down can cause soft metals to detach, and in severe cases, lead to engine seizure. Therefore, after noticing overheating, do not immediately turn off the engine; instead, keep it idling to cool down as much as possible. Blockage: When cooling, avoid splashing cold water on the engine to prevent sudden thermal contraction and potential blockage. The correct method is to wear gloves, place a folded wet cloth over the radiator cap, and gently loosen it slightly to allow steam to escape slowly. Once the radiator pressure drops, add cool water or antifreeze.

What does misfire mean?

In fact, misfire refers to engine cylinder misfire. Definition of misfire: Engine misfire means that during normal operation, one or several cylinders fail to combust properly. The air-fuel mixture in these cylinders cannot be ignited, and the unburned mixture is expelled into the exhaust manifold and then enters the catalytic converter. Since the temperature inside the catalytic converter is extremely high, the unburned mixture will combust there. Serious consequences of misfire: Severe misfire can cause the catalytic converter to overheat and burn out (typically, catalytic converters can withstand temperatures up to 1200 degrees Celsius, and under normal engine operation, the temperature does not exceed 920 degrees Celsius). Checking for misfire is simple: after starting the engine, let it idle and observe whether there is abnormal shaking during operation, and whether this shaking has a clear periodic pattern.

Should You Use the External Air Circulation When Running the Car AC in Summer?

You should use the external air circulation when running the car AC in summer. The correct way to turn on the car AC in summer is: first turn on the external air circulation to expel the hot air inside the car. After feeling a significant drop in the cabin temperature, you can then switch to internal air circulation. Internal Air Circulation System: The air exchange channel between the inside and outside of the car is closed. When the fan is off, the airflow inside the car does not circulate. When the fan is on, the inhaled airflow comes only from inside the car, forming an internal airflow circulation. External Air Circulation System: The external air circulation mode uses the fan to draw air from outside the car into the cabin. The air blown by the fan comes from outside the car. Even if the fan is off, airflow is still drawn into the car while driving, replenishing fresh air inside the car.
