The fuel system is generally composed of components such as the fuel pump, fuel filter, and fuel injector. Its function is to ensure the required fuel flow for the engine under various working conditions and states. Below is some introduction to the fuel system: 1. The fuel system handles fuel filling and transportation, ensuring that fuel smoothly reaches the engine to power it. It is also responsible for collecting fuel vapors and filtering them before releasing them into the atmosphere. 2. The principle of adsorption and desorption in its evaporation system is that fuel vapors are generated in the fuel tank due to changes in environmental temperature. When the vapor pressure exceeds the system's set pressure, the system's bidirectional valve opens, allowing the vapors to enter the charcoal canister, where they are adsorbed by activated carbon.

When I first started driving, I didn't know much about the fuel system, only that it was the gasoline supply pipeline that made the car run. Simply put, the fuel system is a set of devices that starts from the fuel tank and ends at the engine, responsible for storing gasoline and delivering it precisely to the engine for combustion. The main components include the fuel tank for storing fuel, the fuel pump for extracting gasoline to the front of the engine, the filter for purifying impurities in the oil, and the fuel injector for spraying the right amount of oil mist to mix with air. Without it, the engine would be starved, causing unstable idling or even stalling. In daily driving, this system is most afraid of dirt and blockages, such as not changing the filter for a long time or using poor-quality fuel, which can lead to fuel pump wear and increased fuel consumption. I once experienced engine shaking after refueling on the highway, and the repair shop said it was due to a clogged filter. Therefore, regular maintenance is essential; checking it during every oil change can extend the car's lifespan. Modern cars also incorporate electronic controls to adjust fuel injection for improved efficiency. Neglecting maintenance can lead to costly repairs, so driving safety comes first.

Over these years of modifying cars, I've paid special attention to the details of the fuel system. It's far more than just delivering fuel—it's the critical backbone of engine performance. At its core are the fuel tank supply, fuel pump pressurization, filter purification, and fuel injectors atomizing gasoline into the cylinders. A high-quality system can enhance combustion efficiency—for instance, upgrading to high-flow injectors boosts horsepower, but poor matching can damage the engine. I once struggled with sluggish acceleration on the track, only to discover insufficient fuel pump pressure was the bottleneck. For maintenance, timely cleaning of injectors and replacing filters prevent carbon buildup, saving fuel costs with every service. Abnormal fuel consumption often signals leaks or aging components. Remember, regular system inspections are essential to keeping your beloved car in peak condition.

What is the method for adjusting spark plug gap?

The method for adjusting spark plug gap is: 1. Determine the standard gap value for your vehicle's spark plugs. You can use a large flat-head screwdriver with the spark plug metal casing as a fulcrum to pry; 2. Use a feeler gauge to find the appropriate metal blade that matches the spark plug gap; 3. Insert the corresponding thickness blade from the feeler gauge into the spark plug gap - if it fits snugly, it means the spark plug gap matches the blade thickness (multiple feeler gauge blades can be stacked if needed); 4. Select a 0.9mm or 1.0mm blade from the feeler gauge, place it between the spark plug electrodes, and use pliers to adjust until the blade fits snugly; 5. Repeatedly test with the feeler gauge until the blade fits properly.

The Difference Between Plastic Restorer and Dashboard Wax

Dashboard wax primarily consists of methyl silicone oil as its main chemical component, while plastic restorer and yellowing remover can restore the original color of aged and yellowed plastic. Dashboard Wax: Dashboard wax, also known as instrument wax, is a specialized maintenance product designed for the texture of automotive leather trims, instrument panels, and other components. It effectively prevents aging of dashboards and interior trims while offering cleaning and anti-static properties as a liquid wax. Plastic Restorer and Yellowing Remover: It can restore the original color of aged and yellowed plastic, filling the gap where plastic aging issues were previously unsolvable. The product is simple to use—no need to disassemble equipment casings. Applying the product for just 2-4 hours can restore the plastic's original color, making the equipment look brand new.

What is the effect of the Phideon's air suspension?

Phideon's air suspension effect combines the comfort of a sedan with the off-road capability of an SUV. Working principle of air suspension: The air suspension system mainly consists of a control computer, air compressor, pressure storage tank, pneumatic front and rear shock absorbers, and an air distributor. Functions of air suspension: Vehicle level control, vehicle level adjustment, and ADS function. The system uses an air compressor to generate compressed air, which is then delivered to the air chambers of springs and shock absorbers. Height sensors are installed near both front and rear wheels. Based on signals from these height sensors, the vehicle's computer determines changes in vehicle height and controls the compressor and exhaust valve to compress or extend the springs, thereby achieving shock absorption effects and adjusting vehicle height.
