If the needle valve and valve body of the fuel injector are not tightly sealed, seized each other or oil dripping occurs, remove the fuel injector first and clean the needle valve and valve body with clean diesel oil. If the sealing cone surface between the needle valve and the valve body When there are slight pits and pits, they should be ground on special equipment or pliers (note that the grinding paste must not enter the sliding surface between the needle valve and the valve body), and then grind with engine oil until the needle valve and the valve body are sealed When the pits and pits on the cone surface disappear and become black and bright, for the injectors that are stuck between the needle valve and the valve body, first take out the needle valve with criss pliers, and then put it in clean diesel oil to clean it. , and then use a relatively fine oil stone or sand bar to grind the stuck protrusion (note that other parts should not be worn), so that the needle valve can slide freely in the valve body, and then grind the sealing cone surface with grinding paste and engine oil up to the above requirements. If there are many pits and pits on the sealing cone surface between the needle valve and the valve body and cannot be repaired, replace the injector with a new one and adjust the fuel injection pressure and fuel atomization quality on the test bench or vehicle to make sure It meets the requirements of use.
