Reasons for High Fuel Tank Pressure at Gas Stations?
1 Answers
When driving, the temperature of gasoline also rises, causing slight volatilization. This results in the formation of gasoline vapor inside the fuel tank, leading to increased pressure. However, a charcoal canister is connected at the top of the fuel tank, designed to absorb these gasoline vapors. When pressure builds up, the vapors are absorbed by the charcoal canister, which then releases the pressure. Under specific operating conditions, these vapors are drawn into the engine cylinders and burned. Therefore, a certain level of pressure inside the fuel tank is normal, though generally not excessive, as the fuel tank is a sealed container and gasoline volatilization is limited. The hissing sound when opening the fuel tank cap doesn't necessarily indicate high pressure; it could also suggest low pressure. If the pressure is indeed high, it's essential to have it checked at a specialized 4S shop. Additional Information: 1. Introduction: Fuel additives, commonly known as "fuel enhancers" or gasoline additives, are complex chemical formulations. 2. Function: These products aim to improve combustion efficiency, reduce fuel consumption, enhance power output, clean carbon deposits, and lower emissions. In practice, their primary use is for carbon deposit removal, where they can eliminate minor carbon buildup and slow down the formation of new deposits.
