What is the difference between carburetor version and EFI version?

The differences between carburetor version and EFI version are: 1. Different in later maintenance: The carburetor version has a simple structure, and ordinary users can disassemble, clean and maintain it by themselves; The EFI version has many parts, and maintenance can only be handed over to professionals. 2. Different working principles: The carburetor version is a process in which the motor drives the engine to rotate, transmits the signal to the ECU to trigger the nozzle and ignition coil to work and ignite the engine; The EFI version refers to the process of computer-controlled air-fuel mixture ratio. 3. Different fuel supply systems: The carburetor version relies on the negative pressure generated when air flows through the carburetor venturi to suck gasoline from the float chamber into the venturi and atomize it into combustible mixture with the air flow; The EFI version measures the amount of air sucked into the engine and then supplies gasoline to the engine in a high-pressure injection manner.

How to Deal with a Deformed Car Door?

Deformed car doors can be repaired through panel beating. A car door consists of the door body, door accessories, and interior trim panels. Its functions are to provide access for the driver and passengers, isolate external disturbances, and to some extent, protect occupants from side impacts. Reasons why a car door may not open include: 1. The remote key is out of battery; 2. The remote control malfunctions; 3. The door lock mechanism itself is faulty, or the door lock cable fails; 4. The door has been subjected to external force, causing deformation of the door hinges and lock pillars. Steps for soundproofing a car door are: 1. Remove the interior trim panel and clean the door surface with a cleaning agent; 2. Cut damping material to an appropriate size and paste it inside the door, then smooth it evenly with a glue scraper; 3. Cut sound-reflecting material to a suitable size and paste it on the inner panel, then smooth it evenly with a glue scraper; 4. Apply sealing material around the speakers and fixing plates; 5. Reinstall the interior trim parts from the inside out as they were originally.

Can I Use My Old License Plate When Buying a New Car?

You can use your old car's license plate on a new car, but there are certain conditions that must be met. The details are as follows: 1. The license plate must be under the same vehicle owner's name. This means the owner of both vehicles must be the same person. 2. The registration location must be the same. This is straightforward—the plates must be from the same region. For example: A Lu Q plate can only be exchanged for another Lu Q plate; a Hu A plate can only be exchanged for another Hu A plate; a Jing A plate can only be exchanged for another Jing A plate. 3. The type of license plate must be the same. This means: a yellow license plate can only be exchanged for another yellow plate; a blue license plate can only be exchanged for another blue plate; a green license plate can only be exchanged for another green plate. 4. The vehicle must be non-commercial. In other words, only private household vehicles are eligible for plate exchange; commercial vehicles such as taxis are not eligible.

Which Gear to Use for Climbing Hills?

Manual transmission vehicles can use 2nd or 3rd gear when climbing hills, while automatic transmission vehicles can use S (Sport) mode, L (Low) mode, or D (Drive) mode. Hill climbing requires greater torque output, so the transmission should maintain lower gears to increase wheel torque. There are three common types of automatic transmissions in vehicles: Dual-Clutch Transmission (DCT), Continuously Variable Transmission (CVT), and Automatic Transmission (AT). 1. The Dual-Clutch Transmission is developed based on manual transmission technology, sharing similar structural components. The key difference is that DCT adds an extra clutch assembly and gear-shift control mechanism - one clutch manages odd-numbered gears while the other controls even-numbered gears. 2. AT represents the most mature and widely adopted automatic transmission technology. It utilizes multiple planetary gear sets to achieve gear ratio changes and torque conversion, connected to the engine via a torque converter. 3. CVT features a relatively simple structure consisting of just two cone pulleys and a steel push belt. The belt's movement along the pulleys enables continuous ratio adjustment for torque multiplication.
