What Components Make Up the Gasoline Engine Fuel Supply System?

Gasoline engine fuel supply system mainly consists of fuel tank, fuel line, fuel pump, carburetor, etc. Functions of the fuel supply system: The role of the gasoline engine fuel supply system is to prepare a certain quantity and concentration of combustible mixture according to the requirements of various engine operating conditions, supply it into the cylinder, and ensure it ignites and burns near the end of compression to expand and perform work. Finally, the supply system should also discharge the combustion product—exhaust gas—into the atmosphere. System structural components: Gasoline supply device: fuel tank (stores fuel), fuel pump (pumps fuel), fuel line (transports), fuel filter (cleans), fuel pressure regulator (maintains constant fuel pressure); Air supply device: air filter, intake silencer in cars; Combustible mixture formation device: carburetor, fuel injector; Combustible mixture supply and exhaust emission device: intake manifold, exhaust manifold, exhaust silencer.
The fuel supply system of a gasoline engine is quite complex, including the fuel tank for storing gasoline, the fuel pump for delivering gasoline to the engine, and the filter for removing impurities to prevent clogging. The fuel injector is responsible for atomizing the fuel and spraying it into the cylinder for combustion. After driving for many years, I've found that maintaining this system is crucial: if the filter isn't replaced on time, impurities can clog the injector, leading to a surge in fuel consumption or even a breakdown. The fuel pump relies on gasoline for cooling, so don't let the tank stay empty for too long, as it can damage the pump. Additionally, aging fuel lines and issues with the pressure regulator can cause unstable fuel pressure, affecting acceleration. I always refuel at reputable gas stations to ensure clean fuel and regularly inspect the system to keep the car running smoothly. For long-distance trips, a reliable fuel system is a lifeline—don't take it lightly.
