EFI fuse refers to the electronic throttle. Below is information about the functions and roles of the electronic throttle. Functions of the electronic throttle: It determines the idle state by signals from the brake light switch and brake pedal switch, disables cruise control, illuminates the EPC light, and stores fault codes in the fault memory. Roles of the electronic throttle: It enables precise control of the throttle opening, which not only improves fuel economy and reduces emissions but also ensures rapid system response for satisfactory handling performance. Additionally, it facilitates idle control, cruise control, and vehicle stability control, simplifying the control system structure. The second role is to monitor the engine's operating conditions. The throttle position sensor has two contacts that determine the working state of the vehicle, ensuring proper operation.

What is the license class for manual transmission vehicles?

Driving a manual transmission car requires a C1 driver's license. C1 is a code for a type of driver's license. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" (Ministry of Public Security Order No. 123), C1 permits driving small and mini passenger vehicles, light and mini cargo vehicles, as well as light and mini special-purpose vehicles. It also allows driving vehicles covered by C2, C3, and C4 license classes. Common types of driver's licenses are as follows: 1. Class A License: Applicants must be at least 18 years old. This license is suitable for 2-wheel, 3-wheel, and 4-wheel motorcycles. 2. Class A1 License: Applicants must be at least 16 years old. This license is suitable for light motorcycles and also covers Class B1 vehicles. 3. Class B License: Applicants must be at least 18 years old. This license is suitable for vehicles with up to 9 seats (including the driver's seat) and a maximum weight of 3.5 tons (including trailers not exceeding 750 kg). Drivers with at least 2 years of experience can also operate motorcycles with engines up to 125cc and 15 horsepower, as well as 3-wheel and 4-wheel heavy motorcycles. 4. Class B1 License: Applicants must be at least 16 years old. This license is suitable for 3-wheel motorcycles and 4-wheel heavy motorcycles with a power output of up to 15 kW and a weight of up to 550 kg. Class C License: Applicants must be at least 18 years old. This license is suitable for trucks weighing over 3.5 tons with trailers not exceeding 750 kg. This license is valid for 5 years and can be renewed after a medical examination. 5. Class D License: Applicants must be at least 21 years old and hold a Class B license. This license is suitable for passenger vehicles with more than 8 seats (excluding the driver) and trailers not exceeding 750 kg.

How to Remove Paint from a Car?

If it is ordinary paint (alkyd enamel), it can be wiped off with thinner; if it is baked paint, mechanical methods are generally required for removal, such as sanding with fine sandpaper first, followed by polishing; if it is water-based paint, simply wash it with car shampoo. Below is relevant information about automotive paint: 1. Function: Automotive paint is a protective film sprayed onto cars, a type of coating that makes the car body less susceptible to corrosion. 2. Precautions: Refer to safety technical data before use; thoroughly stir the paint before use to ensure uniform color; always wear protective gear, including a respirator and work clothes, when using it.

How much over the speed limit is driving at 85 in an 80 zone?

Driving at 85km/h in an 80km/h speed limit zone is considered speeding, exceeding the limit by 6.25% (calculation: (85-80) ÷80x100%=6.25%). Below are the legal regulations regarding speeding from the "Road Traffic Safety Law of the People's Republic of China": 1. Article 42: When driving on the road, motor vehicles shall not exceed the maximum speed indicated by speed limit signs. On road sections without speed limit signs, safe driving speeds shall be maintained. When driving at night or on road sections prone to danger, as well as under weather conditions such as sandstorms, hail, rain, snow, fog, or icy roads, driving speed shall be reduced. 2. Article 44: When passing through intersections, motor vehicles shall proceed according to traffic signals, signs, markings, or the direction of traffic police; when passing through intersections without traffic signals, signs, markings, or traffic police direction, vehicles shall slow down and yield to pedestrians and vehicles with the right of way.

Which is Better: Dry Dual Clutch or Wet Dual Clutch?

Wet dual clutch is better than dry dual clutch, but it is also more expensive. Wet dual clutch refers to a multi-plate clutch system where two sets of clutches, one large and one small, are coaxially installed together. They are housed in a sealed oil chamber filled with hydraulic fluid, giving the wet clutch structure better adjustment capabilities and superior thermal properties. It can transmit larger torque without damage. However, due to layout and friction material selection factors, the overall size of a wet dual clutch is larger than that of a dry dual clutch. Below is a detailed comparison between wet dual clutch and dry dual clutch: 1. Differences: The key difference between wet and dry dual clutches lies in the working environment of their clutch plates. In a wet dual clutch, the clutch plates are immersed in transmission fluid, whereas in a dry dual clutch, the plates directly contact the engine flywheel. From a perspective of technical maturity and reliability, wet dual clutches are more stable because the hydraulic fluid helps dissipate heat from the clutch plates. Dry dual clutches, on the other hand, suffer from poor heat dissipation, making them prone to overheating or even burning in congested urban driving conditions. In this regard, wet dual clutch transmissions are more mature in technology. However, wet dual clutches are more complex in structure, have higher manufacturing costs, and their power transmission efficiency is lower than that of dry dual clutches. 2. Advantages: Wet dual clutches are stable and mature, capable of achieving fast and smooth gear shifts without interruption. Additionally, the fluid helps dissipate heat at low speeds, preventing overheating. 3. Disadvantages: Naturally, due to their complex structure, wet dual clutches are larger and heavier, with significantly higher manufacturing costs compared to dry dual clutches. They also require more time and effort to maintain and need regular cooling fluid replacements.

Should You Shift to Neutral at Red Lights with an Automatic Transmission?

Automatic transmission cars should be shifted to neutral when waiting at red lights. Here is an introduction to gear shifting knowledge for automatic transmission cars: 1. Practice at red lights: The correct approach when waiting at red lights with an automatic transmission is to use 'Neutral gear + handbrake.' This method does not harm the car, as the Neutral gear disconnects the engine from the transmission's power transfer, and the handbrake prevents situations like rolling collisions. 2. Auto Start-Stop function: After activating this function by pressing the button, the vehicle will automatically brake once it comes to a stop, eliminating the need to shift from reverse or drive gears, keeping the vehicle in a parked state. However, not shifting into neutral still poses certain safety risks, such as rapid acceleration if the accelerator is accidentally pressed, which can easily lead to collision accidents.
