How to Maintain the Fuel System?

1 Answers

Automotive fuel system maintenance includes: fuel pump, fuel lines, filter, fuel rail, fuel injectors, fuel pressure regulator, etc. Regular use of fuel additives for cleaning is sufficient. For new vehicles, it is generally recommended to add protective agents when cleaning the fuel system at around 50,000 kilometers. Fuel system maintenance includes: 1. The fuel system consists of the fuel tank, fuel lines, and fuel injectors, with components such as the fuel pump and fuel filter in the system. Fuel enters the combustion chamber through the fuel pump, fuel filter, and fuel injectors to burn and generate power; 2. The fuel lines are filled with gum formed by fuel oxidation. Due to atmospheric phenomena such as rain and car washing, moisture inevitably enters the fuel tank and fuel lines. Excessive gum can cause premature failure of the fuel filter and clogging of fuel injectors, while moisture can lead to premature wear of the fuel pump and rusting of metal components in the fuel lines; 3. Different types and qualities of gasoline can result in varying degrees of gum and moisture accumulation. For example, gasoline in China is currently divided into three categories: unleaded gasoline, ethanol gasoline, and methanol gasoline. Unleaded gasoline is further classified into three types: National IV, National III, and National II. Unleaded gasoline produces more gum than ethanol and methanol gasoline, while ethanol and methanol gasoline are more prone to absorbing moisture.

What Causes a Car to Stall When Starting?

The main reasons for a car stalling when starting are: 1. Fuel quality issues. This is relatively simple to check—just switch to a different fuel type. 2. Excessive carbon buildup in the throttle body. It should be cleaned at a professional repair shop or 4S store. 3. Low fuel pump pressure or malfunction, which can easily lead to insufficient fuel supply. If the vehicle has been parked for a long time, the engine oil may become too viscous, causing the car to stall. Warming up the car after starting can resolve this. Additional Information: Correct steps for starting a car: 1. Press the car's one-touch start button. 2. The car's dashboard lights up, and the vehicle starts. 3. Fully depress the car's clutch pedal. 4. Push the car's gear lever forward. 5. Slowly release the car's clutch pedal. 6. Gradually press the car's accelerator, and the vehicle will start moving.

What does Level 3 waterlogged vehicle mean?

Level 3 waterlogged vehicle means that the water has almost completely submerged the tires, at which point the water level inside the vehicle will completely inundate the seat cushions and the central armrest area, while also affecting a large number of electrical components. Waterlogging Level 1: The water has just reached the vehicle's chassis, and the vehicle floor may become damp, but the likelihood of significant water ingress is low, with minimal impact on the vehicle's electrical components. Waterlogging Level 2: The water has submerged half of the wheels. Due to the vehicle's incomplete sealing, water will begin to enter the interior. For lower-body sedans, the water level inside may affect the seat adjustment motors as well as electrical components like heating and ventilation. Waterlogging Level 3: The water has almost completely submerged the tires, at which point the water level inside the vehicle will completely inundate the seat cushions and the central armrest area, while also affecting a large number of electrical components.

What causes frequent cylinder head cracking in Chaochai NGD engines?

Most cases result from thermal stress caused by cylinder heads operating under abnormally high temperatures. Here are relevant explanations: 1. Temperature: The allowable temperature for gray cast iron cylinder heads is generally below 350°C for standard grades and above 375°C for low-alloy grades. When temperatures exceed the casting's critical threshold, the material's creep strength decreases, causing plastic deformation - the primary source of residual tensile stress. The presence of residual tensile stress is the root cause of thermal fatigue cracks in cylinder heads. 2. Full-load operation: During full-load engine operation, the cylinder head bridge area adjacent to the combustion chamber reaches extremely high temperatures, causing metal expansion. However, this expansion is constrained by surrounding fastening screws, thereby generating compressive stress.

What does GLS mean in vehicles?

GLS in vehicles refers to the high-end configuration, where different configurations of the same model are categorized into: basic configuration, luxury configuration, and high-end configuration. Taking the Mercedes-Benz GLS as an example: this car measures 5214 mm in length, 1956 mm in width, and 1823 mm in height, with a wheelbase of 3135 mm. In terms of power, this car is equipped with a 2.5T turbocharged engine and a 3.0T turbocharged engine, paired with a 9-speed automatic transmission. For the suspension, the front suspension uses a double-wishbone independent suspension, and the rear suspension also uses a double-wishbone independent suspension. In terms of appearance, this car adopts the family design language, featuring the iconic double-slat grille at the front, combined with a honeycomb mesh and the Mercedes logo embedded.

Is it harmful if water reaches the car chassis?

If the water level just reaches the chassis, it generally won't cause significant issues as long as the car isn't submerged for an extended period. Here's the explanation: 1. Hazards of water-damaged vehicles: It's difficult to guarantee the reliability of such vehicles, and the likelihood of future malfunctions increases. Cars contain numerous electronic components that, if water-damaged, can affect long-term reliability—even after replacements. 2. Odor issues: After water damage, common treatments like rinsing, drying, and sun exposure may not reach hidden areas, which can become breeding grounds for bacteria and produce unpleasant odors.

Can non-Beijing residents buy cars in Beijing?

Yes. Here is the relevant information on obtaining a Beijing license plate: 1. Short-term lease: The lessor rents out idle license plates to those in need, typically for a period of 1-5 years. 2. Back-to-back buyout: Pay a certain fee to buy out the right to use the license plate from its owner. 3. Transfer through marriage using a personal license plate: The downside of this method is that you actually need to get married, but the advantage is that it's a permanent solution. 4. Purchase a shell company with a license plate quota: The benefit of this approach is that it's completely legal, but the drawbacks are also obvious—high purchase costs and ongoing maintenance expenses.
