Is Fuel System Cleaner Necessary for Maintenance?

It is not necessary; simply changing the engine oil and oil filter is sufficient. Additional extended information is as follows: 1. Introduction to the Fuel System: The fuel system generally consists of the fuel pump, fuel filter, fuel injector, etc., and its function is to ensure the fuel flow required by the engine under various working states and conditions. 2. Function and Principle: The fuel system undertakes fuel filling and transportation, ensuring that fuel smoothly reaches the engine to provide power for its operation. It is also responsible for collecting fuel vapor and filtering it before releasing it into the atmosphere. The adsorption and desorption principle of the evaporation system is that fuel vapor is generated in the fuel tank due to changes in ambient temperature. When the vapor pressure exceeds the system's set pressure, the system's bidirectional valve opens, allowing the fuel vapor to enter the charcoal canister, where it is adsorbed by activated carbon. When the internal pressure of the system is lower than the set pressure, the bidirectional valve opens, allowing outside air to enter the system through the charcoal canister to replenish it. When the engine is running, the ECU detects the conditions for opening the charcoal canister purge valve, the purge valve opens, and the fuel vapor enters the engine under the negative pressure of the intake manifold to participate in combustion.
