Fuel Leakage Treatment in Diesel Engine

Diesel engines are the most widely used power elements in agriculture and construction equipment, and most agricultural and construction equipment are powered by diesel engines. However, the phenomenon of diesel engine fuel leakage is also common. How to save fuel costs, please deal with the following situations ingeniously.

Fuel injector return: The fuel injector is a precision component. If the diesel engine is not clean or the machine is used for a long time, it will return fuel due to the wear of the injector. However, because the replacement of the fuel injector is expensive and uneconomical, in order to avoid the leakage of the return fuel, the fuel can be led back to the fuel tank through the fuel return pipe, or the diesel fuel filter can be introduced. If the fuel return pipe is damaged, use a piece of plastic pipe to introduce the fuel into a self-contained container, filter it and then pour it back into the fuel tank.

Fuel leakage in the fuel delivery part: It can be handled appropriately according to the situation: the washer of the hollow screw of the oil delivery pipe is not flat, you can remove the washer, grind it flat and then put it on, if the problem cannot be solved, you can replace it with a new washer, or use a thicker soft plastic material Cut it into a washer and replace it; the fuel leakage between the plastic fuel pipe and the metal joint is mostly caused by the hardening or rupture of the plastic fuel pipe. The hardened and broken parts can be cut off, then scalded with hot water to soften, and installed on the metal joint while hot, and then use metal The wire is tightly bound; if the metal fuel pipeline breaks and leaks fuel, the rupture can be welded by brazing. In addition, in order to prevent the rupture of the fuel pipeline, when installing the fuel pipeline, the camber should be appropriate, do not install it by force, and the pipe body should not be in contact with the fuselage to avoid wear and tear.

Valve cover fuel leakage: When the valve cover is installed, if the tightening force is too large, it is easy to deform and leak fuel. At this time, the valve cover of the fuel leakage can be removed, and the valve cover can be carefully pounded with a wooden stick to make the contact surface flat. Then, put the gasket on it and install it.
