Regularly Replace Fuel Filters: The fuel filter acts as the "mask" of the fuel supply system. Replace it according to the maintenance schedule to ensure effective filtration and prevent contaminants from entering the injectors.

 

Check Injector Atomization: Periodically inspect injectors for proper atomization. Poor atomization leads to incomplete combustion, reduced power, and increased fuel consumption. ‌

 

‌Maintain Fuel System Sealing‌: Regularly inspect fuel lines, fittings, and other components. Promptly repair leaks to prevent fuel waste and air ingress, which can disrupt injection stability.‌

 

‌Adhere to Maintenance Intervals‌: Perform scheduled engine maintenance to prevent issues like incomplete oil scraping and reduced combustion efficiency caused by abnormal wear (e.g., cylinder liner scoring, piston ring failure).‌
