CLEAN FUEL TIPS

Avoid Fuel Contamination to Extend Engine Life

Even tiny amounts of dirt and dust in your machine's fuel system can become obstructions to the engine's normal processes. Newer engines are even more susceptible to damage, because the fuel injection pressure is higher, and the smallest particles can impair normal engine functions.

When dirt and dust are introduced to an area in the engine where quick, sliding movements are important, wear can be accelerated when these small particles interfere with the sliding movement. Examples of these parts are inner and outer valves, nozzle needles and seats, and command piston sliding portions. Two areas where dirt and dust can cause particularly harmful damage are at the interface between the injector barrel and plunger and on the control valves.

The amount of fluid required to keep the operation smooth and continuous between the injector barrel and plunger is just 2.5 microns. The introduction of dirt or dust into this area could cause significant interference with this movement.

A decrease in engine power occurs when the control valves, which maintain fuel pressure, begin leaking. Such leaks are caused when contaminants wear away seals.

How to stop dirt and dust from entering the fuel line

Properly maintain all fueling equipment. When you refuel, always replace the nozzle back onto the pump, rather than letting it fall on the ground where it could gather dust.

Construction equipment often operates in a dusty environment. You can prevent dust from entering the fuel system by making sure the vent tube and fuel tank caps are tightly sealed.

While servicing your equipment, minimize the possibility of exposing the engine to the air, which will minimize the risk of introducing dirt and dust into the fuel system. Whenever you change filters, refuel or make any type of engine repairs, accomplish these tasks indoors, if possible, where there is less chance of contamination.
