What Causes the Abnormal Noise in the Kuga Fuel Tank?
1 Answers
Main reason is a clogged carbon canister. Below is an introduction to the carbon canister: 1. Introduction: The carbon canister is usually installed between the fuel tank and the engine. Since gasoline is a volatile liquid, the fuel tank is often filled with vapor at normal temperatures. The fuel evaporation emission control system is designed to direct these vapors into the combustion process and prevent them from escaping into the atmosphere. 2. Working Process: Activated carbon has adsorption properties. When the car is running or turned off, gasoline vapors from the fuel tank enter the upper part of the carbon canister through pipes, while fresh air enters from the lower part. 3. Principle: The carbon canister is actually part of the Evaporative Emission Control System (EVAP), which is introduced to prevent fuel vapors from escaping into the atmosphere after the engine stops running.
