The fuel supply system consists of the following components: gasoline supply device, air supply device, combustible gas mixture formation device, and exhaust emission device. 1. Gasoline supply device: fuel tank, fuel pump, fuel pipe, gasoline filter, fuel pressure regulator. Air supply device: air filter. Combustible gas mixture formation device: carburetor, fuel injector; Exhaust emission device: intake pipe, exhaust pipe, exhaust muffler. 2. Function of the fuel supply system: Fully mix air with atomized gasoline to form a combustible mixture, then supply the combustible mixture to the engine, while appropriately controlling the supply quantity and concentration to keep the engine running continuously and stably, and finally discharge the generated exhaust gas through the exhaust emission device. 3. Maintenance of the fuel supply system: Cleaning of the fuel tank and fuel supply pipeline. Cleaning of the fuel injector: Turn off the engine, disconnect the power supply of the fuel pump, remove the fuel pipe, find a suitable connector to connect with the engine fuel rail, add cleaning agent to the equipment liquid storage tank, then connect the power supply, adjust the pressure to the specified pressure of the car, and the cleaning can be completed.

What is the Difference Between 4S Store Spray Paint and Original Factory Paint?

4S store spray paint and original factory paint differ in the following aspects: 1. Variety: Original factory paint refers to the paint applied during production in the factory, with the topcoat typically being amino paint that undergoes high-temperature baking. Currently, 4S stores mainly use polyurethane paint, which cures at room temperature or dries through low-temperature baking. 2. Repair level: While 4S stores can achieve the effect of original factory paint, it is not the genuine original factory paint. Processes like electrophoresis within the original factory paint cannot be replicated by 4S stores or repair shops; they can only repair the top three layers: the primer layer, color layer, and clear coat layer. 3. Lifespan: The lifespan of 4S store spray paint is shorter compared to original factory paint. The quality of the spray paint largely depends on paint mixing, the spraying environment, and the technical skill of the workers. Paint mixing may seem simple, but achieving the right mix is not easy. Complex car paints use color codes and computer analysis for tinting, while simpler ones involve manual addition of colorants and comparative tinting, adjusted bit by bit. It is impossible for the mixed paint to perfectly match the original factory paint, but the color difference is generally unnoticeable to the naked eye.

Why was the Geely Haoyue discontinued?

Body dimensions: The length, width, and height of the Geely Haoyue are 4835 1900 1780mm, with a maximum wheelbase of 2815mm, which is very excellent among models of the same level. The body contour of the Geely Haoyue is very square, and combined with its burly size, it easily gives a sense of oppression. Moreover, the whirlwind-style wheels of the Geely Haoyue are also very handsome, creating a quite strong sporty aura.

How to Use Cruise Control in Volkswagen Lavida?

Here is how to use the cruise control in Volkswagen Lavida: 1. The cruise control switch of Volkswagen Lavida is located on the lower left side of the steering wheel. Its main functions include turning off/resuming cruise control, setting speed limits, speed adjustment, and distance adjustment for the sports version. 2. Pressing CNL cancels the cruise control, while 0/1 turns it off. Press RES to resume cruise control. 3. The cruise control function does not activate immediately after turning on the switch. The SET button is used to set the desired speed. (Note: It can only be activated when the speed is above 30km/h.) 4. The silver buttons are used to adjust the speed value, with the left/right buttons controlling speed decrease/increase respectively. 5. The middle cylindrical button can also be used to manually set the following distance. Precautions for using cruise control are as follows: 1. Cruise control does not have automatic braking function, while adaptive cruise control is more intelligent and solves this problem. However, full automation of electronic devices still needs gradual improvement, so drivers should remain attentive to road conditions. 2. When the driver presses the brake pedal, cruise control stops working. The speed value is not cleared and can be restored to continue cruising. 3. In situations like heavy rain or winding mountain roads, please turn off the cruise function and switch to careful manual driving. 4. On downhill slopes, the vehicle may accelerate. Use the foot brake to assist and turn off cruise control if necessary.
