Technical details and manufacturing context for Fuel Tank

Definition

The fuel tank is a critical component of the fuel system that safely stores liquid fuel (gasoline, diesel, or alternative fuels) and supplies it to the engine via the fuel pump and delivery system. It must maintain structural integrity, prevent leaks, manage fuel vapors, and often includes baffles to prevent sloshing during vehicle motion. This directory entry covers fuel tanks used in motor vehicle manufacturing, with typical parameters for passenger vehicles and light trucks. Common materials include high-density polyethylene (HDPE), steel, and aluminum. Reference parameters include nominal capacity (40–200 L per GB/T 18296), burst pressure (≥3.0 MPa per GB/T 18296), leakage rate (≤0.5 mL/min per GB/T 18296), operating temperature (-40–85 °C per ISO 16750-4), material grade (HDPE per ASTM D4976), wall thickness (3–6 mm), weight (5–15 kg), ingress protection (IP67 per IEC 60529), and electrical resistance (≤10^6 Ω per GB/T 18296). These values are reference ranges and must be confirmed for the specific model and application. The fuel tank operates under atmospheric or slight pressure, with a fuel pump (internal or external) drawing fuel to the engine. Ventilation systems manage vapor pressure, fuel level sensors monitor quantity, and safety features like rollover valves and impact protection are often incorporated. When selecting a fuel tank, verify compatibility with the vehicle's fuel type, mounting constraints, and applicable standards. Maintenance signals include visible damage, leaks, or fuel odor. Failure boundaries include structural rupture, leakage, or vapor emission. Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

Fuel is stored in the tank under atmospheric pressure or slight pressure. A fuel pump (either internal or external) draws fuel from the tank and delivers it to the engine. The tank includes ventilation systems to manage vapor pressure, fuel level sensors to monitor quantity, and often incorporates safety features like rollover valves and impact protection.
