How to Use the Automotive Fuel System?

Automotive fuel system usage method: Regularly add high-quality fuel system cleaner (use once every 20,000 kilometers). It can effectively remove gum, carbon deposits, and deposits from the combustion chamber, intake and exhaust valves, fuel injectors, and fuel lines during vehicle operation, keeping all parts of the fuel system clean. The function of the fuel system is to supply the engine with a certain amount of clean, well-atomized gasoline according to the operating conditions of the engine, so as to mix with a certain amount of air to form a combustible mixture. At the same time, the fuel system also needs to store a considerable amount of gasoline to ensure that the car has a considerable driving range.
The automotive fuel system is actually quite delicate, and I pay special attention to these details when driving. Don't rush to rev the engine when starting; wait for the RPM to stabilize before moving, allowing the fuel pump to build proper pressure. Only refuel at reputable gas stations and use the correct gasoline grade to avoid clogging the fuel injectors. Maintaining a steady speed while driving is the most fuel-efficient, as sudden acceleration wastes fuel and strains the system. Waiting until the fuel tank is nearly empty to refuel is a big no-no—the fuel pump relies on gasoline immersion for cooling, so I always refuel when a quarter remains. Before long highway trips, I add some fuel system cleaner to keep the fuel lines clean, and I replace the fuel filter every 50,000 kilometers to ensure smooth fuel delivery. Seasonal changes require checking fuel lines for aging or cracks, and winter demands extra caution to prevent wax buildup. A car, like a person, needs proper care to last a long time.
I pay special attention to my car's fuel system and monitor it closely during every maintenance. The gasoline filter is replaced approximately every 20,000 kilometers to prevent impurities from entering the injection system. I always refuel at chain gas stations where prices are transparent and fuel quality is guaranteed, avoiding any questionable stations. I never overfill the tank, stopping when the pump clicks off to avoid affecting the charcoal canister's function. Before using the AC in summer, I check fuel consumption—a sudden increase might indicate a fuel pressure valve issue. If the car sits unused for long periods, I keep the tank half full to prevent oxidation and corrosion, and let the engine warm up before driving to circulate the fuel. If I notice unstable idling, I immediately check the fuel injection, using a diagnostic tool to analyze data streams. Maintaining these habits has kept my engine in excellent condition with virtually no fuel-related issues.
Understanding how the automotive fuel system operates is essential for proper usage. Fuel in the tank is pressurized by an electric pump and filtered to remove impurities. It then travels through fuel lines to the engine compartment, where it's distributed by the fuel rail and atomized through injectors. The engine control unit (ECU) regulates fuel injection based on throttle input—pressing the accelerator essentially increases fuel delivery. Avoid abrupt starts to prevent sudden fuel surges; steady driving best preserves the system. Always opt for clean 92 or 95 octane fuel, as off-brand gasoline may contain contaminants that clog injectors. Refuel before the tank empties, as the pump relies on gasoline for cooling. Replace the fuel filter every 30,000-40,000 km to maintain unobstructed fuel flow. System malfunctions may cause engine shuddering or power loss—prompt inspection is crucial.
